A comment on Show HN: Is_ready – Wait for many services to become available – 0 Dependencies. Parent comment
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.
