How to make Docker Compose wait for container X before starting Y?
You can make Docker Compose wait for a container X to be fully up and running before starting container Y by using the
depends_on option in your
depends_on option allows you to specify dependencies between services. By default, Docker Compose starts all services simultaneously, but you can use
depends_on to specify that a service should wait for another service to be fully up and running before starting.
Here is an example
docker-compose.yml file that shows how to use the
version: "3" services: service-x: build: . ports: - "8080:8080" service-y: build: . ports: - "8081:8081" depends_on: - service-x
In this example, we have two services,
depends_on option is used to specify that
service-y should wait for
service-x to be fully up and running before starting. This means that Docker Compose will start
service-x first and wait for it to be fully up and running before starting
Note that the
depends_on option does not guarantee that the dependent service is fully up and running, it only waits for the container to be started. It is recommended to use a health check to make sure that the dependent service is fully up and running before starting the dependent service.
