Bolt can't find my task

Run bolt task show and look for any warnings related to your task metadata.

Make sure your task name is valid: Task names must

  • Be lowercase

  • Start with a letter

  • Can only contain letters, numbers and underscores

Make sure your task executable is named the same as your task metadata. For example, if your task is named mytask.rb, you must name your metadata file mytask.json.

My task fails mysteriously

Try running Bolt with --debug to see the exact output from your task.

Make sure your task executable starts with a shebang (#!) line indicating the interpreter to use and verify that the executable is present on the target system. For example, if you write a Python task and include the line: #!/usr/bin/env python, Bolt attempts to execute the script using the default python executable on the target system.

Bolt can't connect to my hosts over SSH

Host key verification failures

This will show up as an error similar to the following:

fingerprint SHA256:6+fv7inQSgU2DuYF5NolTlGF6xM8RBRTw1W6B9rbHkc is unknown for "hostname.example.com,10.16.112.82"

When connecting over SSH, Bolt checks the host key against the fingerprint in ~/.ssh/known_hosts to verify the host is the one it's expecting to connect to. This error means that there is no key for the host in ~/.ssh/known_hosts, so Bolt doesn't know how to tell if it's the right host.

If you can connect to the host over SSH outside Bolt, you can store the SSH host key fingerprint with ssh-keyscan hostname.example.com >> ~/.ssh/known_hosts.

You can disable this check entirely with --no-host-key-check on the CLI or the host-key-check: false option under the ssh section of bolt.yaml. Note that doing so will reduce the security of your SSH connection.

Timeout or connection refused

By default, Bolt tries to connect over the standard SSH port 22. If you need to connect over a different port, either include the port in the name of the target (hostname.example.com:2345) or set it in your Bolt config or inventory.

Bolt can't connect to my Windows hosts

Timeout or connection refused

By default, Bolt tries to connect over SSH. Make sure you've specified the winrm protocol for the target. There are three ways to specify winrm:

  • Include the winrm in the name of the target. For example: winrm://hostname.example.com

  • Pass --transport winrm on the CLI

  • Set the winrm transport in your Bolt config or inventory: For example:

    ...
    config:
      transport: winrm

Puppet log functions are not logging to the console

The default log level for the console is warn. If you use a notice function in a plan, Bolt does not print it to the console. When you have messages you want to be printed to the console regardless of log level you should use the out::message plan function. The out::message function is not available for use in an apply block and only accepts string values.

If you need to send a message that is not a string value or is in an apply block, you can use the warning Puppet log function.

If you only wish to see the output in the console when executing your plan with the --debug flag, use the notice Puppet log function. The notice function sets the console log level to debug for that run.

For more information, see the docs for configuring Bolt's log level.

'Extensions are not built' error message

If you see a gem related error similar to the following:

    Ignoring nokogiri-1.10.2 because its extensions are not built. Try: gem pristine nokogiri --version 1.10.2
    Ignoring unf_ext-0.0.7.5 because its extensions are not built. Try: gem pristine unf_ext --version 0.0.7.5

Use the Bolt-provided gem command to reinstall/install these gems. For example:

    sudo /opt/puppetlabs/bolt/bin/gem pristine nokogiri --version 1.10.2
    sudo /opt/puppetlabs/bolt/bin/gem pristine unf_ext --version 0.0.7.5
