This quick tutorial is going to cover how to pull a Docker image and run a container.

1. List or Search For a Docker Image

Before we can pull a Docker image and run a container, we should know its name first. And to do that, we can go to the Docker hub or Docker store to search for any name.

The alternative way is to use the docker search command to list or search for a Docker image. Let’s see the following example which we search for an Ubuntu docker from the default public registry:

After we pull a Docker image from Docker registry, to run a Docker container from that image, we can use the docker run command which has basic syntax as following:

Let’s see an example which we run the above ubuntu docker image:
