How to Run an Image with Container Name
If you want to run a Docker image with a specific container name, you can use the --name
flag. This flag allows you to specify a custom name for your container instead of relying on a randomly generated one. Here are the steps:
Step 1: Pull the Image from Docker Hub
The first step is to pull the image you want to run from Docker Hub. You can do this using the following command:
docker pull <image-name>
Replace <image-name>
with the name of the image you want to pull.
Step 2: Run the Image with a Container Name
Once you have pulled the image, you can run it with a custom container name using the following command:
docker run --name <container-name> <image-name>
Replace <container-name>
with the name you want to give your container and <image-name>
with the name of the image you pulled in Step 1.
If you want to run the container in detached mode (i.e., in the background), you can add the -d
flag:
docker run -d --name <container-name> <image-name>
Step 3: Verify the Container is Running
You can verify that your container is running with the custom name using the following command:
docker ps
This will list all running containers on your system. Look for the container with the name you specified in Step 2.
Other Ways to Run an Image with a Container Name
There are other ways to run an image with a custom container name, such as:
- Using a Docker Compose file
- Starting a container with a custom name from a stopped container
- Renaming an existing container using the
docker rename
command
However, the method described above is the simplest and most straightforward way to run an image with a custom container name.
That's it! You now know how to run a Docker image with a specific container name using the --name
flag.
