[Here's a guide to understanding Github](https://guides.github.com/introduction/flow/). #### Forking the Azure/Guest-Configuration-Extension repository Unless you are working with multiple contributors on the same file, we ask that you fork the repository and submit your Pull Request from there. [Here's a guide to forks in Github](https://guides.github.com/activities/forking/). ### Code of Conduct This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/). For more information see the [Code of Conduct FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or contact [opencode@microsoft.com](mailto:opencode@microsoft.com) with any additional questions or comments. ## Making Changes ### Pull Requests You can find all of the pull requests that have been opened in the [Pull Request](https://github.com/Azure/Guest-Configuration-Extension/pulls) section of the repository. To open your own pull request, click [here](https://github.com/Azure/WALinuxAgent/compare). When creating a pull request, keep the following in mind: - Make sure you are pointing to the fork and branch that your changes were made in - Choose the correct branch you want your pull request to be merged into - The pull request template that is provided **should be filled out**; this is not something that should just be deleted or ignored when the pull request is created - Deleting or ignoring this template will elongate the time it takes for your pull request to be reviewed ### Pull Request Guidelines A pull request template will automatically be included as a part of your PR. Please fill out the checklist as specified. Pull requests **will not be reviewed** unless they include a properly completed checklist. #### Cleaning up Commits If you are thinking about making a large change, **break up the change into small, logical, testable chunks, and organize your pull requests accordingly**. Often when a pull request is created with a large number of files changed and/or a large number of lines of code added and/or removed, GitHub will have a difficult time opening up the changes on their site. This forces the Azure Guest-Configuration-Extension team to use separate software to do a code review on the pull request. If you find yourself creating a pull request and are unable to see all the changes on GitHub, we recommend **splitting the pull request into multiple pull requests that are able to be reviewed on GitHub**. If splitting up the pull request is not an option, we recommend **creating individual commits for different parts of the pull request, which can be reviewed individually on GitHub**. For more information on cleaning up the commits in a pull request, such as how to rebase, squash, and cherry-pick, click [here](https://github.com/Azure/azure-powershell/blob/dev/documentation/cleaning-up-commits.md). #### General guidelines The following guidelines must be followed in **EVERY** pull request that is opened. - Title of the pull request is clear and informative - There are a small number of commits that each have an informative message - A description of the changes the pull request makes is included, and a reference to the issue being resolved, if the change address any - All files have the Microsoft copyright header #### Testing Guidelines The following guidelines must be followed in **EVERY** pull request that is opened. - Pull request includes test coverage for the included changesAzure-WALinuxAgent-a976115/.github/ISSUE_TEMPLATE/000077500000000000000000000000001510742556200211155ustar00rootroot00000000000000Azure-WALinuxAgent-a976115/.github/ISSUE_TEMPLATE/bug_report.md000066400000000000000000000016351510742556200236140ustar00rootroot00000000000000--- name: Bug report about: Create a report to help us improve title: "[BUG] Bug Title" --- **Describe the bug: A clear and concise description of what the bug is.** Note: Please add some context which would help us understand the problem better 1.

Our daily automation tests most of these distributions. The Agent can be used on other distributions as well, but development, testing and support for those are done by the open source community. This repo contains community-driven support for some distributions which are not officially supported by Azure. Testing is done using the develop branch, which can be unstable. For a stable build please use the master branch instead. [![CodeCov](https://codecov.io/gh/Azure/WALinuxAgent/branch/develop/graph/badge.svg)](https://codecov.io/gh/Azure/WALinuxAgent/branch/develop) ## Introduction The Microsoft Azure Linux Agent (waagent) manages Linux provisioning and VM interaction with the Azure Fabric Controller. It provides the following functionality for Linux IaaS deployments: * Image Provisioning * Creation of a user account * Configuring SSH authentication types * Deployment of SSH public keys and key pairs * Setting the host name * Publishing the host name to the platform DNS * Reporting SSH host key fingerprint to the platform * Resource Disk Management * Formatting and mounting the resource disk * Configuring swap space * Networking * Manages routes to improve compatibility with platform DHCP servers * Ensures the stability of the network interface name * Kernel * Configure virtual NUMA (disable for kernel <2.6.37) * Configure SCSI timeouts for the root device (which could be remote) * Diagnostics * Console redirection to the serial port * SCVMM Deployments * Detect and bootstrap the VMM agent for Linux when running in a System Center Virtual Machine Manager 2012R2 environment * VM Extension * Inject component authored by Microsoft and Partners into Linux VM (IaaS) to enable software and configuration automation * VM Extension reference implementation on [GitHub](https://github.com/Azure/azure-linux-extensions) ## Communication The information flow from the platform to the agent occurs via two channels: * A boot-time attached DVD for IaaS deployments. This DVD includes an OVF-compliant configuration file that includes all provisioning information other than the actual SSH keypairs. * A TCP endpoint exposing a REST API used to obtain deployment and topology configuration. ### HTTP Proxy The Agent will use an HTTP proxy if provided via the `http_proxy` (for `http` requests) or `https_proxy` (for `https` requests) environment variables. Due to limitations of Python, the agent *does not* support HTTP proxies requiring authentication. Similarly, the Agent will bypass the proxy if the environment variable `no_proxy` is set. Note that the way to define those environment variables for the Agent service varies across different distros. For distros that use systemd, a common approach is to use Environment or EnvironmentFile in the [Service] section of the service definition, for example using an override or a drop-in file (see "systemctl edit" for overrides). Example ```bash # cat /etc/systemd/system/walinuxagent.service.d/http-proxy.conf [Service] Environment="http_proxy=http://proxy.example.com:80/" Environment="https_proxy=http://proxy.example.com:80/" # ``` The Agent passes its environment to the VM Extensions it executes, including `http_proxy` and `https_proxy`, so defining a proxy for the Agent will also define it for the VM Extensions. The [`HttpProxy.Host` and `HttpProxy.Port`](#httpproxyhost-httpproxyport) configuration variables, if used, override the environment settings. Note that this configuration variables are local to the Agent process and are not passed to VM Extensions. ## Requirements The following systems have been tested and are known to work with the Azure Linux Agent. Please note that this list may differ from the official list of supported systems on the Microsoft Azure Platform as described [here](https://docs.microsoft.com/en-us/azure/virtual-machines/linux/endorsed-distros). Waagent depends on some system packages in order to function properly: * Python 2.6+ * OpenSSL 1.0+ * OpenSSH 5.3+ * Filesystem utilities: sfdisk, fdisk, mkfs, parted * Password tools: chpasswd, sudo * Text processing tools: sed, grep * Network tools: ip-route, iptables ## Installation Installing via your distribution's package repository is the only method that is supported. You can install from source for more advanced options, such as installing to a custom location or creating custom images. Installing from source, though, may override customizations done to the Agent by your distribution, and is meant only for advanced users. We provide very limited support for this method. To install from source, you can use **setuptools**: ```bash sudo python setup.py install --register-service ``` For Python 3, use: ```bash sudo python3 setup.py install --register-service ``` You can view more installation options by running: ```bash sudo python setup.py install --help ``` The agent's log file is kept at `/var/log/waagent.log`. Lastly, you can also customize your own RPM or DEB packages using the configuration samples provided in the deb and rpm sections below. This method is also meant for advanced users and we provide very limited support for it. ## Upgrade Upgrading via your distribution's package repository or using automatic updates are the only supported methods. More information can be found here: [Update Linux Agent](https://learn.microsoft.com/en-us/azure/virtual-machines/extensions/update-linux-agent) To upgrade the Agent from source, you can use **setuptools**. Upgrading from source is meant for advanced users and we provide very limited support for it. ```bash sudo python setup.py install --force ``` Restart waagent service,for most of linux distributions: ```bash sudo service waagent restart ``` For Ubuntu, use: ```bash sudo service walinuxagent restart ``` For CoreOS, use: ```bash sudo systemctl restart waagent ``` ## Command line options ### Flags `-verbose`: Increase verbosity of specified command `-force`: Skip interactive confirmation for some commands ### Commands `-help`: Lists the supported commands and flags. `-deprovision`: Attempt to clean the system and make it suitable for re-provisioning, by deleting the following: * All SSH host keys (if Provisioning.RegenerateSshHostKeyPair is 'y' in the configuration file) * Nameserver configuration in /etc/resolv.conf * Root password from /etc/shadow (if Provisioning.DeleteRootPassword is 'y' in the configuration file) * Cached DHCP client leases * Resets host name to localhost.localdomain **WARNING!** Deprovision does not guarantee that the image is cleared of all sensitive information and suitable for redistribution. `-deprovision+user`: Performs everything under deprovision (above) and also deletes the last provisioned user account and associated data. `-version`: Displays the version of waagent `-serialconsole`: Configures GRUB to mark ttyS0 (the first serial port) as the boot console. This ensures that kernel bootup logs are sent to the serial port and made available for debugging. `-daemon`: Run waagent as a daemon to manage interaction with the platform. This argument is specified to waagent in the waagent init script. `-start`: Run waagent as a background process `-collect-logs [-full]`: Runs the log collector utility that collects relevant agent logs for debugging and stores them in the agent folder on disk. Exact location will be shown when run. Use flag `-full` for more exhaustive log collection. ## Configuration A configuration file (/etc/waagent.conf) controls the actions of waagent. Blank lines and lines whose first character is a `#` are ignored (end-of-line comments are *not* supported). A sample configuration file is shown below: ```yml Extensions.Enabled=y Extensions.GoalStatePeriod=6 Provisioning.Agent=auto Provisioning.DeleteRootPassword=n Provisioning.RegenerateSshHostKeyPair=y Provisioning.SshHostKeyPairType=rsa Provisioning.MonitorHostName=y Provisioning.DecodeCustomData=n Provisioning.ExecuteCustomData=n Provisioning.PasswordCryptId=6 Provisioning.PasswordCryptSaltLength=10 ResourceDisk.Format=y ResourceDisk.Filesystem=ext4 ResourceDisk.MountPoint=/mnt/resource ResourceDisk.MountOptions=None ResourceDisk.EnableSwap=n ResourceDisk.EnableSwapEncryption=n ResourceDisk.SwapSizeMB=0 Logs.Verbose=n Logs.Collect=y Logs.CollectPeriod=3600 OS.AllowHTTP=n OS.RootDeviceScsiTimeout=300 OS.EnableFIPS=n OS.OpensslPath=None OS.SshClientAliveInterval=180 OS.SshDir=/etc/ssh HttpProxy.Host=None HttpProxy.Port=None ``` The various configuration options are described in detail below. Configuration options are of three types : Boolean, String or Integer. The Boolean configuration options can be specified as "y" or "n". The special keyword "None" may be used for some string type configuration entries as detailed below. ### Configuration File Options #### __Extensions.Enabled__ _Type: Boolean_ _Default: y_ This allows the user to enable or disable the extension handling functionality in the agent. Valid values are "y" or "n". If extension handling is disabled, the goal state will still be processed and VM status is still reported, but only every 5 minutes. Extension config within the goal state will be ignored. Note that functionality such as password reset, ssh key updates and backups depend on extensions. Only disable this if you do not need extensions at all. _Note_: disabling extensions in this manner is not the same as running completely without the agent. In order to do that, the `provisionVMAgent` flag must be set at provisioning time, via whichever API is being used. We will provide more details on this on our wiki when it is generally available. #### __Extensions.WaitForCloudInit__ _Type: Boolean_ _Default: n_ Waits for cloud-init to complete (cloud-init status --wait) before executing VM extensions. Both cloud-init and VM extensions are common ways to customize a VM during initial deployment. By default, the agent will start executing extensions while cloud-init may still be in the 'config' stage and won't wait for the 'final' stage to complete. Cloud-init and extensions may execute operations that conflict with each other (for example, both of them may try to install packages). Setting this option to 'y' ensures that VM extensions are executed only after cloud-init has completed all its stages. Note that using this option requires creating a custom image with the value of this option set to 'y', in order to ensure that the wait is performed during the initial deployment of the VM. #### __Extensions.WaitForCloudInitTimeout__ _Type: Integer_ _Default: 3600_ Timeout in seconds for the Agent to wait on cloud-init. If the timeout elapses, the Agent will continue executing VM extensions. See Extensions.WaitForCloudInit for more details. #### __Extensions.GoalStatePeriod__ _Type: Integer_ _Default: 6_ How often to poll for new goal states (in seconds) and report the status of the VM and extensions. Goal states describe the desired state of the extensions on the VM. _Note_: setting up this parameter to more than a few minutes can make the state of the VM be reported as unresponsive/unavailable on the Azure portal. Also, this setting affects how fast the agent starts executing extensions. #### __AutoUpdate.UpdateToLatestVersion__ _Type: Boolean_ _Default: y_ Enables auto-update of the Extension Handler. The Extension Handler is responsible for managing extensions and reporting VM status. The core functionality of the agent is contained in the Extension Handler, and we encourage users to enable this option in order to maintain an up to date version. When this option is enabled, the Agent will install new versions when they become available. When disabled, the Agent will not install any new versions, but it will use the most recent version already installed on the VM. _Notes_: 1. This option was added on version 2.10.0.8 of the Agent. For previous versions, see AutoUpdate.Enabled. 2. If both options are specified in waagent.conf, AutoUpdate.UpdateToLatestVersion overrides the value set for AutoUpdate.Enabled. 3. Changing config option requires a service restart to pick up the updated setting. For more information on the agent version, see our [FAQ](https://github.com/Azure/WALinuxAgent/wiki/FAQ#what-does-goal-state-agent-mean-in-waagent---version-output).
For more information on the agent update, see our [FAQ](https://github.com/Azure/WALinuxAgent/wiki/FAQ#how-auto-update-works-for-extension-handler).
For more information on the AutoUpdate.UpdateToLatestVersion vs AutoUpdate.Enabled, see our [FAQ](https://github.com/Azure/WALinuxAgent/wiki/FAQ#autoupdateenabled-vs-autoupdateupdatetolatestversion).
#### __AutoUpdate.Enabled__ _Type: Boolean_ _Default: y_ Enables auto-update of the Extension Handler. This flag is supported for legacy reasons and we strongly recommend using AutoUpdate.UpdateToLatestVersion instead. The difference between these 2 flags is that, when set to 'n', AutoUpdate.Enabled will use the version of the Extension Handler that is pre-installed on the image, while AutoUpdate.UpdateToLatestVersion will use the most recent version that has already been installed on the VM (via auto-update). On most distros the default value is 'y'. #### __Provisioning.Agent__ _Type: String_ _Default: auto_ Choose which provisioning agent to use (or allow waagent to figure it out by specifying "auto"). Possible options are "auto" (default), "waagent", "cloud-init", or "disabled". #### __Provisioning.Enabled__ (*removed in 2.2.45*) _Type: Boolean_ _Default: y_ This allows the user to enable or disable the provisioning functionality in the agent. Valid values are "y" or "n". If provisioning is disabled, SSH host and user keys in the image are preserved and any configuration specified in the Azure provisioning API is ignored. _Note_: This configuration option has been removed and has no effect. waagent now auto-detects cloud-init as a provisioning agent (with an option to override with `Provisioning.Agent`). #### __Provisioning.MonitorHostName__ _Type: Boolean_ _Default: n_ Monitor host name changes and publish changes via DHCP requests. #### __Provisioning.MonitorHostNamePeriod__ _Type: Integer_ _Default: 30_ How often to monitor host name changes (in seconds). This setting is ignored if MonitorHostName is not set. #### __Provisioning.UseCloudInit__ _Type: Boolean_ _Default: n_ This options enables / disables support for provisioning by means of cloud-init. When true ("y"), the agent will wait for cloud-init to complete before installing extensions and processing the latest goal state. _Provisioning.Enabled_ must be disabled ("n") for this option to have an effect. Setting _Provisioning.Enabled_ to true ("y") overrides this option and runs the built-in agent provisioning code. _Note_: This configuration option has been removed and has no effect. waagent now auto-detects cloud-init as a provisioning agent (with an option to override with `Provisioning.Agent`). #### __Provisioning.DeleteRootPassword__ _Type: Boolean_ _Default: n_ If set, the root password in the /etc/shadow file is erased during the provisioning process. #### __Provisioning.RegenerateSshHostKeyPair__ _Type: Boolean_ _Default: y_ If set, all SSH host key pairs (ecdsa, dsa and rsa) are deleted during the provisioning process from /etc/ssh/. And a single fresh key pair is generated. The encryption type for the fresh key pair is configurable by the Provisioning.SshHostKeyPairType entry. Please note that some distributions will re-create SSH key pairs for any missing encryption types when the SSH daemon is restarted (for example, upon a reboot). #### __Provisioning.SshHostKeyPairType__ _Type: String_ _Default: rsa_ This can be set to an encryption algorithm type that is supported by the SSH daemon on the VM. The typically supported values are "rsa", "dsa" and "ecdsa". Note that "putty.exe" on Windows does not support "ecdsa". So, if you intend to use putty.exe on Windows to connect to a Linux deployment, please use "rsa" or "dsa". #### __Provisioning.MonitorHostName__ _Type: Boolean_ _Default: y_ If set, waagent will monitor the Linux VM for hostname changes (as returned by the "hostname" command) and automatically update the networking configuration in the image to reflect the change. In order to push the name change to the DNS servers, networking will be restarted in the VM. This will result in brief loss of Internet connectivity. #### __Provisioning.DecodeCustomData__ _Type: Boolean_ _Default: n_ If set, waagent will decode CustomData from Base64. #### __Provisioning.ExecuteCustomData__ _Type: Boolean_ _Default: n_ If set, waagent will execute CustomData after provisioning. #### __Provisioning.PasswordCryptId__ _Type: String_ _Default: 6_ Algorithm used by crypt when generating password hash. * 1 - MD5 * 2a - Blowfish * 5 - SHA-256 * 6 - SHA-512 #### __Provisioning.PasswordCryptSaltLength__ _Type: String_ _Default: 10_ Length of random salt used when generating password hash. #### __ResourceDisk.Format__ _Type: Boolean_ _Default: y_ If set, the resource disk provided by the platform will be formatted and mounted by waagent if the filesystem type requested by the user in "ResourceDisk.Filesystem" is anything other than "ntfs". A single partition of type Linux (83) will be made available on the disk. Note that this partition will not be formatted if it can be successfully mounted. #### __ResourceDisk.Filesystem__ _Type: String_ _Default: ext4_ This specifies the filesystem type for the resource disk. Supported values vary by Linux distribution. If the string is X, then mkfs.X should be present on the Linux image. SLES 11 images should typically use 'ext3'. BSD images should use 'ufs2' here. #### __ResourceDisk.MountPoint__ _Type: String_ _Default: /mnt/resource_ This specifies the path at which the resource disk is mounted. #### __ResourceDisk.MountOptions__ _Type: String_ _Default: None_ Specifies disk mount options to be passed to the mount -o command. This is a comma separated list of values, ex. 'nodev,nosuid'. See mount(8) for details. #### __ResourceDisk.EnableSwap__ _Type: Boolean_ _Default: n_ If set, a swap file (/swapfile) is created on the resource disk and added to the system swap space. #### __ResourceDisk.EnableSwapEncryption__ _Type: Boolean_ _Default: n_ If set, the swap file (/swapfile) is mounted as an encrypted filesystem (flag supported only on FreeBSD.) #### __ResourceDisk.SwapSizeMB__ _Type: Integer_ _Default: 0_ The size of the swap file in megabytes. #### __Logs.Verbose__ _Type: Boolean_ _Default: n_ If set, log verbosity is boosted. Waagent logs to /var/log/waagent.log and leverages the system logrotate functionality to rotate logs. #### __Logs.Collect__ _Type: Boolean_ _Default: y_ If set, agent logs will be periodically collected and uploaded to a secure location for improved supportability. NOTE: This feature relies on the agent's resource usage features (cgroups); this flag will not take effect on any distro not supported. #### __Logs.CollectPeriod__ _Type: Integer_ _Default: 3600_ This configures how frequently to collect and upload logs. Default is each hour. NOTE: This only takes effect if the Logs.Collect option is enabled. #### __OS.AllowHTTP__ _Type: Boolean_ _Default: n_ If SSL support is not compiled into Python, the agent will fail all HTTPS requests. You can set this option to 'y' to make the agent fall-back to HTTP, instead of failing the requests. NOTE: Allowing HTTP may unintentionally expose secure data. #### __OS.EnableRDMA__ _Type: Boolean_ _Default: n_ If set, the agent will attempt to install and then load an RDMA kernel driver that matches the version of the firmware on the underlying hardware. #### __OS.EnableFIPS__ _Type: Boolean_ _Default: n_ If set, the agent will emit into the environment "OPENSSL_FIPS=1" when executing OpenSSL commands. This signals OpenSSL to use any installed FIPS-compliant libraries. Note that the agent itself has no FIPS-specific code. _If no FIPS-compliant certificates are installed, then enabling this option will cause all OpenSSL commands to fail._ #### __OS.EnableFirewall__ _Type: Boolean_ _Default: n (set to 'y' in waagent.conf)_ Creates firewall rules to allow communication with the VM Host only by the Agent. #### __OS.MonitorDhcpClientRestartPeriod__ _Type: Integer_ _Default: 30_ The agent monitor restarts of the DHCP client and restores network rules when it happens. This setting determines how often (in seconds) to monitor for restarts. #### __OS.RootDeviceScsiTimeout__ _Type: Integer_ _Default: 300_ This configures the SCSI timeout in seconds on the root device. If not set, the system defaults are used. #### __OS.RootDeviceScsiTimeoutPeriod__ _Type: Integer_ _Default: 30_ How often to set the SCSI timeout on the root device (in seconds). This setting is ignored if RootDeviceScsiTimeout is not set. #### __OS.OpensslPath__ _Type: String_ _Default: None_ This can be used to specify an alternate path for the openssl binary to use for cryptographic operations. #### __OS.RemovePersistentNetRulesPeriod__ _Type: Integer_ _Default: 30_ How often to remove the udev rules for persistent network interface names (75-persistent-net-generator.rules and /etc/udev/rules.d/70-persistent-net.rules) (in seconds) #### __OS.SshClientAliveInterval__ _Type: Integer_ _Default: 180_ This values sets the number of seconds the agent uses for the SSH ClientAliveInterval configuration option. #### __OS.SshDir__ _Type: String_ _Default: `/etc/ssh`_ This option can be used to override the normal location of the SSH configuration directory. #### __HttpProxy.Host, HttpProxy.Port__ _Type: String_ _Default: None_ If set, the agent will use this proxy server for HTTP/HTTPS requests. These values *will* override the `http_proxy` or `https_proxy` environment variables. Lastly, `HttpProxy.Host` is required (if to be used) and `HttpProxy.Port` is optional. #### __CGroups.EnforceLimits__ _Type: Boolean_ _Default: y_ If set, the agent will attempt to set cgroups limits for cpu and memory for the agent process itself as well as extension processes. See the wiki for further details on this. #### __CGroups.Excluded__ _Type: String_ _Default: customscript,runcommand_ The list of extensions which will be excluded from cgroups limits. This should be comma separated. #### __Protocol.EndpointDiscovery__ _Type: String_ _Default: dhcp_ Determines how the agent will discover the [WireServer endpoint](https://learn.microsoft.com/en-us/azure/virtual-network/what-is-ip-address-168-63-129-16). Agent will use DHCP by default to discover the WireServer endpoint, but if this setting is 'static' the agent will use the known WireServer address (168.63.129.16). Possible options are "dhcp" (default) or "static". ### Telemetry WALinuxAgent collects usage data and sends it to Microsoft to help improve our products and services.

Flush - move all state files to a new directory under .../history/timestamp/. 2. Archive - enumerate all directories under .../history/timestamp and create a .zip file named timestamp.zip. Delete the archive directory 3. Purge - glob the list .zip files, sort by timestamp in descending order, keep the first 50 results, and delete the rest. ... is the directory where the agent's state resides, by default this is /var/lib/waagent.

Most subcommands are not meant to be run directly by the user. However, some subcommands may be useful for debugging (such as collect-logs, version, and show-configuration) and deprovisioning. .SH SUBCOMMANDS .TP \fB-collect-logs\fR Runs the log collector utility that collects relevant agent logs for debugging and stores them in the agent folder on disk. Exact location will be shown when run. Use flag \fB-full\fR for more exhaustive log collection. .TP \fB-configuration-path FILE\fR Used together with \fB-start\fR or \fB-daemon\fR to specify configuration file. Default to /etc/waagent.conf. .TP \fB-daemon -start\fR Run waagent as a daemon in background. .TP \fB-deprovision\fR Attempt to clean the system and make it suitable for re-provisioning. WARNING: Deprovision does not guarantee that the image is cleared of all sensitive information and suitable for redistribution. .TP \fB-deprovision+user\fR Same as \fB-deprovision\fR, but also removes the last provisioned user account. .TP \fB-register-service\fR Register waagent as a service and enable it. .TP \fB-run-exthandlers\fR Run check for updates to waagent and extension handler. Note that outputs to /dev/console will be temporarily suspended. .TP \fB-setup-firewall=IP\fR Set up firewall rules for endpoint \fBIP\fR. .TP \fB-show-configuration\fR Print the current configuration, including values read from waagent.conf. .TP \fB-help\fR Display usage information. .TP \fB-version\fR Show the current version of the agent. .SH CONFIGURATION The agent is configured via this file by default: .B /etc/waagent.conf This file contains key=value settings that control agent behavior, including provisioning, disk formatting, resource limits, and certificate handling. Example entries: .RS Provisioning.Enabled=y ResourceDisk.Format=y ResourceDisk.MountPoint=/mnt/resource RSA.KeyLength=2048 Logs.Verbose=y .RE .SH FILES AND DIRECTORIES .TP \fB/etc/waagent.conf\fR Main configuration file. .TP \fB/var/lib/waagent\fR State files and provisioning artifacts. .TP \fB/var/log/waagent.log\fR Agent log file. .SH SERVICES On systemd systems, the agent runs as: .RS .B systemctl start .B systemctl enable .RE .SH EXIT STATUS Zero on success, non-zero on error. .SH EXAMPLES .TP Deprovision before capturing an image: .RS waagent -deprovision+user && rm -rf /var/lib/waagent && shutdown -h now .RE .SH SEE ALSO .BR systemctl (1), .BR cloud-init (1) .SH HOMEPAGE .B https://github.com/Azure/WALinuxAgent .B https://learn.microsoft.com/en-us/azure/virtual-machines/extensions/agent-linux .SH COPYRIGHT Copyright 2018 Microsoft Corporation .SH AUTHORS Microsoft Azure Linux Team Azure-WALinuxAgent-a976115/init/000077500000000000000000000000001510742556200163355ustar00rootroot00000000000000Azure-WALinuxAgent-a976115/init/arch/000077500000000000000000000000001510742556200172525ustar00rootroot00000000000000Azure-WALinuxAgent-a976115/init/arch/waagent.service000066400000000000000000000005371510742556200222670ustar00rootroot00000000000000[Unit] Description=Azure Linux Agent Wants=network-online.target sshd.service sshd-keygen.service After=network-online.target ConditionFileIsExecutable=/usr/bin/waagent ConditionPathExists=/etc/waagent.conf [Service] Type=simple ExecStart=/usr/bin/python -u /usr/bin/waagent -daemon Restart=always RestartSec=5 [Install] WantedBy=multi-user.target Azure-WALinuxAgent-a976115/init/azure-vmextensions.slice000066400000000000000000000002141510742556200232410ustar00rootroot00000000000000[Unit] Description=Slice for Azure VM Extensions DefaultDependencies=no Before=slices.target [Slice] CPUAccounting=yes MemoryAccounting=yes Azure-WALinuxAgent-a976115/init/azure.slice000066400000000000000000000001471510742556200205060ustar00rootroot00000000000000[Unit] Description=Slice for Azure VM Agent and Extensions DefaultDependencies=no Before=slices.target Azure-WALinuxAgent-a976115/init/chainguard/000077500000000000000000000000001510742556200204425ustar00rootroot00000000000000Azure-WALinuxAgent-a976115/init/chainguard/90-waagent.preset000066400000000000000000000000171510742556200235400ustar00rootroot00000000000000enable waagent Azure-WALinuxAgent-a976115/init/chainguard/waagent.service000066400000000000000000000006211510742556200234510ustar00rootroot00000000000000[Unit] Description=Azure Linux Agent Wants=network-online.target sshd.service sshd-keygen.service After=network-online.target ConditionFileIsExecutable=/usr/bin/waagent ConditionPathExists=/etc/waagent.conf [Service] Type=simple ExecStart=waagent -daemon Restart=always RestartSec=5 Environment=PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin [Install] WantedBy=multi-user.target Azure-WALinuxAgent-a976115/init/clearlinux/000077500000000000000000000000001510742556200205035ustar00rootroot00000000000000Azure-WALinuxAgent-a976115/init/clearlinux/waagent.service000066400000000000000000000005661510742556200235220ustar00rootroot00000000000000[Unit] Description=Azure Linux Agent Wants=network-online.target sshd.service sshd-keygen.service After=network-online.target ConditionFileIsExecutable=/usr/bin/waagent ConditionPathExists=/usr/share/defaults/waagent/waagent.conf [Service] Type=simple ExecStart=/usr/bin/python -u /usr/bin/waagent -daemon Restart=always RestartSec=5 [Install] WantedBy=multi-user.target Azure-WALinuxAgent-a976115/init/coreos/000077500000000000000000000000001510742556200176275ustar00rootroot00000000000000Azure-WALinuxAgent-a976115/init/coreos/cloud-config.yml000066400000000000000000000023511510742556200227240ustar00rootroot00000000000000#cloud-config coreos: units: -

It can be useful in tests that need to execute commands or access/modify files that are not available in all platforms, or require root privileges, or can change global system settings. For a sample usage see the mock_cgroup_environment() function. Currently, MockEnvironment mocks subprocess.Popen(), fileutil.mkdir(), os.path.exists() and the builtin() open function (it mocks fileutil.mkdir() instead od os.mkdir() because the agent's code users the former since it provides backwards compatibility with Python 2). The mock for Popen looks for a match in the given 'commands' and, if found, forwards the call to the mock_command.py, which produces the output specified by the matching item. Otherwise it forwards the call to the original Popen function. The mocks for the other functions first look for a match in the given 'files' array and, if found, map the file to the corresponding path in the matching item (if the mapping points to an Exception, the Exception is raised). If there is no match, then it checks if the file is included in the given 'paths' array and maps the path to the given 'tmp_dir' (e.g. "/lib/systemd/system" becomes "/lib/systemd/system".) If there no matches, the path is not changed. Once this mapping has completed the mocks invoke the corresponding original function. Matches are done using regular expressions; the regular expressions in 'paths' must create group 0 to indicate the section of the path that needs to be mapped (i.e. use parenthesis around the section that needs to be mapped.) The items in the given 'data_files' are copied to the 'tmp_dir'. The add_*() methods insert new items int the list of mock objects.
