Software Update Plugin

The Software Update Plugin allows receiving notifications about new releases of OctoPrint or installed plugins which registered with it and -- if properly configured -- also applying the found updates.

First Steps

Out of the box the Software Update Plugin will be able to notify you of any updates that might be available for your OctoPrint installation or any plugins that registered themselves with it. In order to also be able to update your OctoPrint installation, you'll need to configure at least OctoPrint's checkout folder, and you also should configure the restart commands for OctoPrint and the whole server.

For configuring the plugin you'll need to go into OctoPrint's Settings Dialog, navigate to the Software Upda.. _section therein and once you are there click on the little wrench icon in the upper right corner.

The Software Update plugin configuration dialog

There you can adjust the following settings:

  • OctoPrint checkout folder: This should be the path to OctoPrint's git checkout folder (/home/pi/OctoPrint for OctoPi or manual installs following the Raspberry Pi setup guide). This must be set to allow updating from within OctoPrint

    Note

    OctoPi releases 0.12.0 and later ship with this already setup for you.

    Note

    OctoPi 0.11.0 users: Please also take a look at the note at the very end of this FAQ entry. Due to a little issue in that OctoPi release 0.11.0 you might have to fix the URL your OctoPrint checkout is using for updating. This can easily be done by SSHing into your OctoPi instance and doing this:

    cd ~/OctoPrint
git remote set-url origin https://github.com/foosel/OctoPrint.git
  • OctoPrint version tracking: Whether you want to track OctoPrint releases or every commit. Usually you want to select "Release" here which is also the default, unless you are a developer.
  • OctoPrint Release Channel: The release channel of OctoPrint to track for updates. If you only want stable versions, select "Stable" here which is also the default. "Maintenance RCs" will also allow you to update to maintenance release candidates, "Devel RCs" will also allow you to update to development release candidates. If in doubt, leave it at "Stable". Read more about Release Channels here.
  • Version cache TTL: The "time to live" of the cache OctoPrint will use to temporarily persist the version information for the various components registered with the plugin, so that they don't have to be queried from the internet every time you load the page. Defaults to 24h, you usually shouldn't need to change that value.

More settings are available by editing the correspondi.. _section in config.yaml <sec-bundledplugins-softwareupdate-configuration>.

That restart commands for OctoPrint and the whole server can be configured under Settings > Server.

Command line usage

The functionality of the Software Update Plugin is also available on OctoPrint's command line interface under the plugins sub command. It's is possible to check for updates via octoprint plugins softwareupdate:check and to apply available updates via octoprint plugins softwareupdate:update. Please the corresponding --help pages on details:

$ octoprint plugins softwareupdate:check --help
Usage: octoprint plugins softwareupdate:check [OPTIONS] [TARGETS]...

  Check for updates.

  If any TARGETs are provided, only those components will be checked.

  Examples:
  - octoprint plugins softwareupdate:check
      This will check all components for available updates,
      utilizing cached version information.
  - octoprint plugins softwareupdate:check --force
      This will check all components for available updates,
      ignoring any cached version information even if it's
      still valid.
  - octoprint plugins softwareupdate:check octoprint
      This will only check OctoPrint itself for available
      updates.

Options:
  --force  Ignore the cache for the update check
  --help   Show this message and exit.
$ octoprint plugins softwareupdate:update --help
Usage: octoprint plugins softwareupdate:update [OPTIONS] [TARGETS]...

  Apply updates.

  If any TARGETs are provided, only those components will be updated.

  Examples:
  - octoprint plugins softwareupdate:update
      This will update all components with a pending update
      that can be updated.
  - octoprint plugins softwareupdate:update --force
      This will force an update of all registered components
      that can be updated, even if they don't have an updated
      pending.
  - octoprint plugins softwareupdate:update octoprint
      This will only update OctoPrint and leave any further
      components with pending updates at their current versions.

Options:
  --force  Update even if already up to date
  --help   Show this message and exit.

Configuring the Plugin

plugins:
  softwareupdate:
    # the time-to-live of the version cache, in minutes
    cache_ttl: 60

    # configured version check and update methods
    checks:
      # "octoprint" is reserved for OctoPrint
      octoprint:
        # this defines an version check that will check against releases
        # published on OctoPrint's Github repository and an update method
        # utilizing an (included) update script that will be run on
        # OctoPrint's checkout folder
        type: github_release
        user: foosel
        repo: OctoPrint
        update_script: '{python} "/path/to/octoprint-update.py" --python="{python}" "{folder}" "{target}"'
        update_folder: /path/to/octoprint/checkout/folder

      # further checks may be define here

    # pip command, if another one than the automatically detected one should be
    # used - should normally NOT be necessary and hence set
    pip_command: /path/to/pip

Version checks

  • github_release: Checks against releases published on Github. Additional config parameters:
    • user: (mandatory) Github user the repository to check belongs to
    • repo: (mandatory) Github repository to check
    • prerelease: True or False, default False, set to True to also include releases on Github marked as prerelease.
    • release_branch: Branch name to check against target_comittish field in Github release data - release will only be included if the values match. Defaults to being unset, in which case no match will be performed.
    • release_compare: Method to use to compare between current version information and release versions on Github. One of python (version comparison using pkg_resources.parse_version, newer version detected if remote > current), semantic (version comparison using semantic_version package, newer version detected if remote > current) and unequal (string comparison, newer version detected if remote != current).
  • github_commit: Checks against commits pushed to Github. Additional config parameters:
    • user: (mandatory) Github user the repository to check belongs to
    • repo: (mandatory) Github repository to check
    • branch: Branch of the Github repository to check, defaults to master if not set.
    • current: Current commit hash. Will be updated automatically.
  • bitbucket_commit: Checks against commits pushed to Bitbucket. Additional config parameters:
    • user: (mandatory) Bitbucket user the repository to check belongs to
    • repo: (mandatory) Bitbucket repository to check
    • branch: Branch of the Bitbucket repository to check, defaults to master if not set.
    • current: Current commit hash. Will be updated automatically.
  • git_commit: Checks a local git repository for new commits on its configured remote. Additional config parameters:
    • checkout_folder: (mandatory) The full path to the folder with a valid git repository to check.
  • command_line: Uses a provided script to determine whether an update is available. Additional config parameters:
    • command: (mandatory) The full path to the script to execute. The script is expected to return a 0 return code if an update is available and to return the display name of the available version as the final and optionally the display name of the current version as the next to final line on stdout.
  • python_checker: Can only be specified by plugins through the hook <sec-bundledplugins-softwareupdate-hooks>. Additional config parameters:
    • python_checker: (mandatory) A python callable which returns version information and whether the current version is up-to-date or not, see below for details.

Update methods

  • pip: An URL to provide to pip install in order to perform the update. May contain a placeholder {target} which will be the most recent version specifier as retrieved from the update check.
  • update_script: A script to execute in order to perform the update. May contain placeholders {target} (for the most recent version specified as retrieved from the update check), {branch} for the branch to switch to to access the release, {folder} for the working directory of the script and {python} for the python executable OctoPrint is running under. The working directory must be specified either by an update_folder setting or if the git_commit check is used its checkout_folder setting.
  • python_updater: Can only be specified by plugins through the hook <sec-bundledplugins-softwareupdate-hooks>. A python callable which performs the update, see below for details.

Common configuration patterns

Example for a setup that allows "bleeding edge" updates of OctoPrint under OctoPi (the update_script gets configured correctly automatically by the plugin itself):

plugins:
  softwareupdate:
    checks:
      octoprint:
        type: github_commit
        user: foosel
        repo: OctoPrint
        branch: devel
        update_folder: /home/pi/OctoPrint

Plugin installed via pip and hosted on Github under https://github.com/someUser/OctoPrint-SomePlugin, only releases should be tracked:

plugins:
  softwareupdate:
    checks:
      some_plugin:
        type: github_release
        user: someUser
        repo: OctoPrint-SomePlugin
        pip: 'https://github.com/someUser/OctoPrint-SomePlugin/archive/{target}.zip'

The same, but tracking all commits pushed to branch devel (thus allowing "bleeding edge" updates):

plugins:
  softwareupdate:
    checks:
      some_plugin:
        type: github_commit
        user: someUser
        repo: OctoPrint-SomePlugin
        branch: devel
        pip: 'https://github.com/someUser/OctoPrint-SomePlugin/archive/{target}.zip'
