Playing With Busybox
Now that we have everything setup, it’s time to get our hands dirty. In this section, we are going to run a Busybox container on our system and get a taste of the docker run
command.
To get started, let’s run the following in our terminal:
$ docker pull busybox
Note: Depending on how you’ve installed docker on your system, you might see a
permission denied
error after running the above command. If you’re on a Mac, make sure the Docker engine is running. If you’re on Linux, then prefix yourdocker
commands withsudo
. Alternatively, you can create a docker group to get rid of this issue.
The pull
command fetches the busybox image from the Docker registry and saves it to our system. You can use the docker images
command to see a list of all images on your system.
$ docker images
