# This script sets up cigocacher, but should never fail the build if unsuccessful.
|
|
# It expects to run on a GitHub-hosted runner, and connects to cigocached over a
|
|
# private Azure network that is configured at the runner group level in GitHub.
|
|
#
|
|
# Usage: ./action.sh
|
|
# Inputs:
|
|
# URL: The cigocached server URL.
|
|
# HOST: The cigocached server host to dial.
|
|
# Outputs:
|
|
# success: Whether cigocacher was set up successfully.
