Some Tips and Tricks for using application.

Removing a container service¶

Docker Standalone¶

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.

docker-compose.yml

services:
  webserver:
    scale: 0
    image: nginx

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.

To delete volumes, networks, and images, you can use the destroy option in the deployment configuration file (See Destroy settings).

Docker Swarm¶

Add the following line to the deploy section of the service in the docker-compose.yml file to remove a service (container) in Docker Swarm mode:

docker-compose.yml

services:
  webserver:
    deploy:
      replicas: 0
    image: nginx
