Docker is a well-known technology for project development and deployment. It introduces the concept of Docker containerization for project deployment. Containers are a fundamental Docker component that contains all dependencies and libraries required for project deployment. When users generate a Docker image, a new container is built automatically, and developers can now name or rename the container.
This post will demonstrate how to name or rename a Docker container.
How to Name or Rename Docker Container?
To name or rename a container, create a container through the Docker images and specify the container name. Developers can also rename the container name later using the “docker rename <old-name> <new-name>” command.
Step 1: Open Terminal
First, open your favorite terminal from the Windows Start menu. For instance, we will use the “Git Bash” terminal:
Step 2: Open Project Directory
Utilize the “cd” command to open the project directory:
List down all files and directories using the “ls” command. Here, you can see we have a Dockerfile. The Docker file contains all instructions that will create a Docker image to instruct the container:
Step 3: Build a Docker Image
Now, build the Docker image with the help of provided command:
Step 4: Create a New Container
In order to build a new container using the newly created Docker image, utilize the “docker container create” command. Here, “i” is used as the interactive flag, the “-t” option is utilized to allocate a pseudo tty terminal that helps in connecting with the container, and the “–name” flag is used to name the container:
Let’s see if the container was created or not by running the “docker ps -a” command:
Step 5: Rename a Container
In order to rename the container, the “docker rename” command can be effective enough:
Again, check the container list to verify if we have successfully renamed the container or not:
We have demonstrated how to name and rename Docker containers.
Conclusion
To name or rename the Docker container, first, create a new Docker image by utilizing the Dockerfile. After that, create a new container and name the container using the “docker container create -i -t –name <container-name> demo” command. In order to rename the container, use the “docker rename <old-name> <new-name>” command. We have elaborated on how to name or rename a Docker container.
