Tips and Tricks

Some Tips and Tricks for using application.

Removing a container service

You can add the scale: 0 option in the docker-compose.yml file to remove a service (container). The scale option sets the number of containers to run for the service. Setting it to 0 will scale the service down to zero containers.

Tip

If you set the scale: 0 option to all services in the docker compose file, the entire project will be stopped and removed, excluding any volumes, networks, and images (See Known Limitations).

Example

In this example, we add the scale: 0 option to the webserver service and push the change to the repository. The webhook will then trigger the deployment, which will stop and remove the container for the webserver service.

services:
  webserver:
    scale: 0  # Add this line to remove the service remotely
    image: nginx
