# Container builds

## Builds the application container image locally
build: test-runner
	$(dockerLocal) build -t=$(image):$(tag) .

## Build the test running container
test-runner:
	$(dockerLocal) build -f test/Dockerfile -t=$(test_image):$(tag) .

## Push the current application container images to the Docker Hub
push:
	$(dockerLocal) push $(image):$(tag)

## Tag the current images as 'latest' and push them to the Docker Hub
ship:
	$(dockerLocal) tag $(image):$(tag) $(image):latest
	$(dockerLocal) push $(image):$(tag)
	$(dockerLocal) push $(image):latest


# ------------------------------------------------
# Test running

## Pull the container images from the Docker Hub
pull:
	docker pull $(image):$(tag)
