Testing if a Docker container is healthy in a Makefile
Published on 2021-02-27 • Modified on 2021-02-27
In this snippet, we will see how to test if a Docker container is healthy in a Makefile. The goal is to use this check before running the tests, for example. They will fail if the database container is not up and ready to be used.
test: phpunit.xml check ## Run main functional and unit tests
check: ## Docker check
@$(DOCKER) info > /dev/null 2>&1 # Docker is up
@test '"healthy"' = `$(DOCKER) inspect --format "{{json .State.Health.Status }}" strangebuzz-db-1` # Db container is up and healthy
