# Builds a cached .tar.gz of the master branch with full history and
|
|
# uploads it to Google Cloud Storage. This archive is downloaded by a
|
|
# script defined by a CI/CD variable named CI_PRE_CLONE_SCRIPT. This has
|
|
# two benefits:
|
|
#
|
|
# 1. It speeds up builds. A 800 MB download only takes seconds.
|
|
# 2. It significantly reduces load on the file server. Smaller deltas
|
|
# means less time spent in git pack-objects.
|
|
#
|
|
# Since the destination directory of the archive depends on the project
|
|
# ID, this is only run on GitLab.com.
|
|
#
|
|
# CI_REPO_CACHE_CREDENTIALS contains the Google Cloud service account
|
|
# JSON for uploading to the gitlab-ci-git-repo-cache bucket. These
|
|
# credentials are stored in the Production vault.
|
|
#
|
|
# Note that this bucket should be located in the same continent as the
|
|
# runner, or network egress charges will apply:
|
|
# https://cloud.google.com/storage/pricing
