How to use the command 'docker rename' (with examples)
This article will demonstrate how to use the ‘docker rename’ command and provide examples of its use cases.
Command Description:
The ‘docker rename’ command is used to rename a Docker container. It allows users to give a container a more descriptive or meaningful name without having to recreate the container. This can be useful when managing and organizing a large number of containers.
Use case 1: Rename a container
Code:
docker rename container new_name
Motivation:
Renaming a container can be useful for better identification and organization. This makes it easier to recognize the purpose or role of a container when managing multiple instances.
Explanation:
- ‘docker rename’ is the command used to rename a container.
- ‘container’ is the current name of the container you want to rename.
- ’new_name’ is the name you want to assign to the container.
Example output:
If we have a container named ‘webapp’ and want to rename it to ‘my_webapp’, we would run the following command:
docker rename webapp my_webapp
Use case 2: Display help
Code:
docker rename --help
Motivation:
When first using a command or when unsure about its usage, it is often helpful to consult the built-in help documentation. The ‘–help’ option provides a detailed description of the command and its available options.
Explanation:
- ‘docker rename’ is the command for which we want to display help information.
- ‘–help’ is the option used to request the command’s built-in documentation.
Example output:
Running the command ‘docker rename –help’ will display the help documentation for the ‘docker rename’ command, including information about its usage and available options.
