How to Use the Docker Rename Command

The docker rename command is used to rename a Docker container. It allows you to change the name of an existing container to a new name of your choice.

To use the docker rename command, you can follow these steps:

Make sure you have Docker installed and running on your system.

Open a terminal or command prompt.

To rename a container, you need to know the container’s current name or ID. You can find the name or ID of the container by using the docker ps command:

    docker ps

    
    
         

This will display a list of running containers along with their details.

Once you have the container’s current name or ID, you can use the docker rename command followed by the current name or ID and the new name:

    docker rename {{current-name-or-id}} {{new-name}}

    
    
         

Replace {{current-name-or-id}} with the actual current name or ID of the container you want to rename, and {{new-name}} with the desired new name for the container.

For example, to rename a container with the current name my-container to new-container, you can use:

    docker rename my-container new-container

    
    
         

After running the docker rename command, Docker will update the name of the container to the new name you specified.

You can verify that the container has been renamed by using the docker ps command again. The container should now appear with the new name in the list of running containers.

Please note that the docker rename command only changes the name of the container. It does not affect the container’s ID or any other properties. Renaming a container can be useful for providing more meaningful or descriptive names to your containers.
