# TODO(https://github.com/googleapis/google-cloud-python/issues/14142):

# Reduce this timeout by moving the installation of Python runtimes to a separate base image

timeout: 7200s # 2 hours for the first uncached run, can be lowered later.

steps:

# STEP 1: Pull the latest version of the image to use as a cache.

# The '|| exit 0' part ensures the build doesn't fail if the image

# doesn't exist yet (e.g., on the very first run).

- name: 'gcr.io/cloud-builders/docker'

entrypoint: 'bash'

args: ['-c', 'docker pull gcr.io/$PROJECT_ID/python-librarian-generator:latest || exit 0']

# STEP 2: Build the new image, using the pulled image as a cache source.

- name: 'gcr.io/cloud-builders/docker'

args:

- 'build'

- '--tag=gcr.io/$PROJECT_ID/python-librarian-generator:latest'

- '--cache-from=gcr.io/$PROJECT_ID/python-librarian-generator:latest'

- '--file=.generator/Dockerfile'

- '.'

# STEP 3: Push the newly built image to the registry so it can be used

# as the cache for the next run. Cloud Build does this automatically if

# the image is listed in the 'images' section.

images:

- 'gcr.io/$PROJECT_ID/python-librarian-generator:latest'

# This section automatically creates a storage bucket for storing docker build logs.
