This article is to share with you about how docker compose manages containers. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

How does docker-compose manage containers? Docker Compose is very similar to Docker Stack. It can deploy and manage multi-container applications in single-engine mode (Single-Engine Mode) on Docker nodes.

It is difficult to deploy and manage a wide range of container services. And this is the problem that Docker Compose is trying to solve. Here are some commands that are commonly used when using Docker Compose.

1) docker-compose up

Used to deploy a Compose application.

By default, this command reads a file named docker-compose.yml or docker-compose.yaml.

Of course, users can also use-f to specify other file names. Typically, the-d parameter is used to cause the application to start in the background.

2) docker-compose stop

Stops all containers related to the Compose application, but does not delete them.

Stopped applications can be easily restarted with the docker-compose restart command.

3) docker-compose rm

Used to delete stopped Compose applications.

It deletes containers and networks, but does not delete volumes and mirrors.

4) docker-compose restart

Restart the stopped Compose application.

If the user changes the application after stopping it, the content of the change will not be reflected in the restarted application, so you need to redeploy the application to make the change take effect.

5) docker-compose ps

Used to list the containers in the Compose application.

The output includes the current status, the commands the container is running, and the network port.

6) docker-compose down

Stop and delete the running Compose application.

It deletes containers and networks, but does not delete volumes and mirrors.

The above is how docker compose manages containers, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
