usage_description="
|
|
Run a command against each GCP project in the current account
|
|
|
|
This is powerful so use carefully!
|
|
|
|
Requires GCloud SDK to be installed and configured and 'gcloud' to be in the \$PATH
|
|
|
|
Sets the core/project in each iteration, and sets back to the original project upon any exit (except kill -9)
|
|
This allows easy chaining with other scripts that operate on the current project
|
|
|
|
All arguments become the command template
|
|
|
|
The command template replaces the following for convenience in each iteration:
|
|
|
|
{id} - with the project id
|
|
{name} - with the project name
|
|
|
|
eg.
|
|
${0##*/} 'echo GCP project has id {id} and name {name}'
|
|
|
|
