Running plans

Sections

Bolt plans allow you to tie together complex workflows that include multiple tasks, scripts, commands, and even other plans. Bolt is packaged with a collection of modules that contain useful plans to support common workflows. For details, see Packaged modules.

To execute a plan, run bolt plan run and specify:

  • The full name of the plan, formatted as <MODULE>::<PLAN>.

  • Any plan parameters, as <PARAMETER>=<VALUE>.

  • (If required) The username and password to access the target. Pass these in as --user and --password command-line options.

For example, imagine a plan that deploys a load balancer. The plan is located at mymodule/plans/myplan.pp and accepts a load_balancer parameter, which is the target that the plan runs its tasks or functions on. If your load balancer was lb.myorg.com, you would use the following command to run the plan:

  • *nix shell command

    bolt plan run mymodule::myplan load_balancer=lb.myorg.com
  • PowerShell cmdlet

    Invoke-BoltPlan -Name mymodule::myplan load_balancer=lb.myorg.com

Remember: You can find the documentation and required parameters for a plan using the bolt plan show <PLAN NAME> command, or the Get-BoltPlan -Name <PLAN NAME> PowerShell cmdlet.

You can pass a comma-separated list of target names, wildcard patterns, or group names to a plan parameter of type TargetSpec. For more information on the TargetSpec type, see Writing plans in the Puppet language.

Plan location

In order for Bolt to find a plan, the plan must be in a module on the modulepath or in a plans/ directory in your Bolt project. If you are developing a new plan, you can create a Bolt project, develop your task in <PROJECT DIRECTORY>/plans/, and run Bolt from the root of your Bolt project directory to test the task.

Passing structured data into a plan

If one of your plan parameters accepts structured data like an array or hash, you can pass the data into the plan as JSON from the command line. The parsed value must match the parameter's type specification in the plan definition.

To pass a single parameter as JSON, use the syntax <PARAMETER>=<VALUE>. Make sure you wrap the JSON value in single quotes to prevent " characters from being swallowed by the shell. For example:

  • *nix shell command

    bolt plan run mymodule::myplan load_balancers='["lb1.myorg.com", "lb2.myorg.com"]'
  • PowerShell cmdlet

    Invoke-BoltPlan -Name mymodule::myplan load_balancers='["lb1.myorg.com", "lb2.myorg.com"]'

If you want to pass multiple structured values or are having trouble with the magic parsing of single parameters, you can pass a single JSON object for all parameters with the params command-line option. For example:

  • *nix shell command

    bolt plan run mymodule::myplan --params '{"load_balancers": ["lb1.myorg.com", "lb2.myorg.com"]}'
  • PowerShell cmdlet

    Invoke-BoltPlan -Name mymodule::myplan -Params '{"load_balancers": ["lb1.myorg.com", "lb2.myorg.com"]}'

You can also load parameters from a file by putting @ before the file name. For example:

  • *nix shell command

    bolt plan run mymodule::myplan --params @param_file.json
  • PowerShell cmdlet

    Invoke-BoltPlan -Name mymodule::myplan -Params '@param_file.json'
