Description

This module will insert a dependency on the completion of the startup script for one or more specified compute VMs and report back if it fails. This can be useful when running post-boot installation scripts that require the startup script to finish setting up a node.

WARNING:: this module is experimental and not fully supported.

Additional Dependencies

  • gcloud must be present in the path of the machine where terraform apply is run.

Example

- id: workstation
  source: modules/compute/vm-instance
  use:
  - network1
  - my-startup-script
  settings:
    instance_count: 4

# Wait for all instances of the above VM to finish running startup scripts.
- id: wait
  source: community/modules/scripts/wait-for-startup
  settings:
    instance_names: $(workstation.name)
