docker-test.sh v0.0.6

Docker Test

Set of bash programs to test a project that uses a Dockerfile to create a runnable image.

Use

npm install docker-test.sh

Implement bin/COMMAND_NAME-hook.sh for each binary you'd like to use. You'll need to expose all non-optional callback functions - just define bash functions of the same name. You'll also need to define the non-optional variables - either set them as env vars at runtime, or define in the hook file.

The binaries are exposed via npm, so ensure your path includes local node_modules/.bin. Run the commands from a directory relative to your bin folder that contains the hooks.

Binaries

docker-test-jenkins

Runs a build for jenkins, where the repo has been checked out.

Hook file: docker-test-jenkins.sh

Variables

Either specify when running the bin, or in callbacks.sh.

# tag for image
IMAGE_TAG=auth-server

# (optional) the repo to tag built images on
DOCKER_REPO_URL=docker-registry.development.yourdomain.com:5000

# (optional) if you have a separate image-file for testing (e.g that installs with 
# testing dependencies) specify its path
TEST_DOCKERFILE=test/Dockerfile

# (optional) CSV of branches to deploy after a test that passes (see run_test_container)
DEPLOY_BRANCHES=dev,master,staging

Public API

build_test_image

Creates an image from a clean version of the git commit. Tags as $IMAGE-TAG-$GIT_COMMIT. By default this is called by test_setup.

Callbacks

test_setup() (optional)

Runs before test container, here you ensure your test environment is ready.

Default is to call build_test_image.

run_test_container()

Executes test. Ensure exit status is 1 on test failures.

test_teardown() (optional)

Cleans up after test run.

after_push() (optional)

Run a functional after an image is pushed (and thus tests have passed).
