The following article explains How to Manage Docker Images and Containers.
In order to manage Docker images and containers, we have the Docker CLI commands or a Docker GUI tool. The following list shows some of the basic commands for managing Docker images and containers.
- Docker images. In order to manage images, we use these commands.
docker images.This command lists all the Docker images that are currently available on your system.docker rmi <IMAGE ID>. Similarly, this command removes the Docker image specified by the <IMAGE ID> parameter.docker pull <IMAGE NAME>:<TAG>. Likewise, this command pulls a Docker image from a registry, such as Docker Hub.
- Docker containers. For the purpose of managing containers, we use these commands.
docker ps. This command lists all the running Docker containers.docker ps -a. Similarly, this command lists all the Docker containers, including those that are not running.docker start <CONTAINER ID>. This command starts a stopped Docker container.docker stop <CONTAINER ID>. Similarly, this command stops a running Docker container.docker rm <CONTAINER ID>. This command removes a Docker container specified by the <CONTAINER ID> parameter.docker exec -it <CONTAINER ID> <COMMAND>. This command executes a command inside a running Docker container.
- Docker Compose. Similarly, we use these commands for Docker Compose.
docker-compose up. In order to start the container, we use this command. So, his command starts the Docker containers defined in the docker-compose.yml file.docker-compose down. Similarly, this command stops and removes the Docker containers created by the docker-compose up command.
In fact, these are just a few examples of the many commands available for managing Docker images and containers. Furthermore, Docker also provides a range of other commands for managing networks, volumes, and other Docker resources.
