Description

Versioning tools for Dockerfile source repos.

• dockerfiles generates versionsed Dockerfiles from on a common template.
• cloudbuild generates a configuration file to build these Dockerfiles using Google Container Builder.

Installation

• Install bazel: https://bazel.build
• Clone this repo:

git clone github.com/GoogleCloudPlatform/runtimes-common
cd runtimes-common/versioning

• Build:

bazel build scripts:all

• Set the path to the built scripts:

export PATH=$PATH:$PWD/bazel-bin/scripts

Create versions.yaml

At root of the Dockerfile source repo, add a file called versions.yaml. Follow the format defined in versions.go. See an example on github.

Primary folders in the Dockerfile source repo:

• templates contains Dockerfile.template, which is a Go template for generating Dockerfiles.
• tests contains any tests that should be included in the generated cloud build configuration.
• Version folders as defined in versions.yaml. The Dockerfiles are generated into these folders. The folders should also contain all supporting files for each version, for example docker-entrypoint.sh files.

Usage of dockerfiles command

cd path/to/dockerfile/repo
dockerfiles

Usage of cloudbuild command

cd path/to/dockerfile/repo
cloudbuild > cloudbuild.yaml

You can use the generated cloudbuild.yaml file as followed:

gcloud container builds submit --config=cloudbuild.yaml .
