Blocks the execution until the defined container is healthy in a Docker Compose environment. Useful if you have to automatize a script after starting some containers (for example in some CI/CD systems like GitLab).
Just install the healthcheck-block package (locally or globally) with npm, yarn, or any other Node dependency manager (for example yarn global add healthcheck-block).
If installed locally with npm, run it with node node_modules/healthcheck-block network container, where network is the name of the network (project), and container is the name of the container (service). For example:
docker-compose up -d
node node_modules/healthcheck-block airbnb php
docker-compose -p airbnb exec php composer updateIf installed locally with yarn, you can also run it with yarn run healthcheck-block. If installed globally (with either npm or yarn), the healthcheck-block console command should be globally available.
As default, we are checking healthiness by executing the healthcheck script (./docker-healthcheck as default), so that your script doesn't have to wait for the next cycle of Docker healthcheck (which is 30 seconds by default). Quite obviously this method does not work, if the healthcheck is defined in the Docker Compose YML file. You can change the script to run with the -script parameter, like:
healthcheck-block airbnb php -script healthcheck.shYou can also wait for a container to be actually marked healthy by Docker with the --wait-healthcheck flag.
If you would like the script to terminate with an error code if the container is still not healthy after a time limit, you can set a timeout in seconds with -timeout, for example:
healthcheck-block airbnb php -timeout 30
