Breakpoint Provisioner

Type: breakpoint

The breakpoint provisioner will pause until the user presses "enter" to resume the build. This is intended for debugging purposes, and allows you to halt at a particular part of the provisioning process.

This is independent of the -debug flag, which will instead halt at every step and between every provisioner.

Basic Example

{
  "type": "breakpoint",
  "note": "foo bar baz"
}

Configuration Reference

Optional

• disable (boolean) - If true, skip the breakpoint. Useful for when you have set multiple breakpoints and want to toggle them off or on. Default: false

• note (string) - a string to include explaining the purpose or location of the breakpoint. For example, you may find it useful to number your breakpoints or label them with information about where in the build they occur

Usage

Insert this provisioner wherever you want the build to pause. You'll see ui output prompting you to press "enter" to continue the build when you are ready.

For example:

==> docker: Pausing at breakpoint provisioner with note "foo bar baz".
==> docker: Press enter to continue.

Once you press enter, the build will resume and run normally until it either completes or errors.
