Use the alias “db” that you have defined in file to refer to the database host name. Containers for the linked service will be reachable at a hostname identical to the alias, or the service name if no alias was specified. Source: https://docs.docker.com/compose/compose-file/compose-file-v2/#links
Since nginx 1.19 you can now use environment variables in your configuration with docker-compose.

The second issue is that volumes are not automatically updated … Read more
You can add this to your docker-compose.yml (assuming your user inside container is root): volumes: – ~/.ssh:/root/.ssh Also you can check for more advanced solution with ssh agent (I did not tried it myself)
Links have been replaced by networks. Docker describes them as a legacy feature that you should avoid using. You can safely remove the link and the two containers will be able to refer to each other by their service name (or container_name). With compose, links do have a side effect of creating an implied dependency. … Read more
Environment variables in docker-compose.yml file should not have quotes when using array definition: db: image: mysql:5.7 ports: – “3306:3306” environment: – MYSQL_ROOT_PASSWORD=secret – MYSQL_USER=django – MYSQL_PASSWORD=secret – MYSQL_DATABASE=myAppDB If you use them in your docker-compose.yml file: db: image: mysql:5.7 ports: – “3306:3306″ environment: – MYSQL_ROOT_PASSWORD=”secret” – MYSQL_USER=”django” – MYSQL_PASSWORD=”secret” – MYSQL_DATABASE=”myAppDB” and run: $ docker-compose … Read more
