How to Run Container in Docker Ubuntu

Docker is a powerful tool that allows you to run applications inside isolated environments called containers. In this guide, we will walk you through the steps to run a container in Docker on an Ubuntu system.

Step 1: Install Docker on Ubuntu

The first step is to install Docker on your Ubuntu system. You can do this by following the official Docker installation guide for Ubuntu. Once Docker is installed, you can start using the docker command to interact with containers.

Step 2: Pull a Docker Image

Before you can run a container, you need to pull a Docker image from Docker Hub or another container registry. You can do this by using the docker pull command followed by the name of the image you want to pull.

Step 3: Run a Docker Container

Now that you have a Docker image, you can run a container using the docker run command. Make sure to specify the image name with the command, and you can also use flags to customize how the container runs.

• For example, to run a container in the background, you can use the -d flag.
• To map ports between the host and the container, you can use the -p flag.
• To mount volumes from the host to the container, you can use the -v flag.

Step 4: Interact with the Container

Once the container is running, you can interact with it using the docker exec command. This allows you to execute commands inside the container, view logs, and more.

Step 5: Stop and Remove the Container

When you are done using the container, you can stop it using the docker stop command followed by the container ID or name. If you want to remove the container, you can use the docker rm command.

Conclusion

Running containers in Docker on Ubuntu is a straightforward process once you get the hang of it. With these steps, you can start running containers and experimenting with different applications in isolated environments.
