Healthchecks are a great way to achieve this. As this repository mentions, this is the example using PostgreSQL. depends_on:
postgres-database:
condition: service_healthy healthcheck:
test: ["CMD-SHELL", "pg_isready"]
interval: 10s
timeout: 5s
retries: 5 However, PostgreSQL has already a command for this called pg_isready. How is this going to work for other cases such as MySQL? |

You could do a query like SHOW DATABASES as a healthcheck for mysql.
