usage_description="
|
|
Parses Terraform Plan output, find all github_team_repository references that would be added, queries the GitHub API to determine if they exist, and if so imports them
|
|
|
|
Terraform Plan is used because the team_id is also needed for import but is often a terraform reference which only resolves at runtime
|
|
|
|
|
|
The GitHub Organization must be specified as the first arg or found in \$GITHUB_ORGANIZATION environment variable
|
|
|
|
If \$TERRAFORM_PRINT_ONLY is set to any value, prints the commands to stdout to collect so you can check, collect into a text file or pipe to a shell or further manipulate, ignore errors etc.
|
|
|
|
Requires Terraform and GitHub CLI to be installed and configured. Tested on Terraform 1.1.6
