The Importance of Using Docker Volumes and How it Saves Time for Developers

Docker volumes can be an incredibly useful tool for developers, allowing them to persist data and configuration changes across multiple runs of a container. By adding a volume to an existing Docker container, developers can save time and effort, and make their development workflows more efficient.

Adding a volume to an existing Docker container can be a useful way to persist data or configuration changes across multiple runs of the container. In this article, we’ll look at a simple example of how to add a volume to an existing Docker container.

First, let’s assume that we have an existing Docker container to that we want to add a volume to. We can use the docker ps command to list all of our runnings and stopped containers:

$ docker ps -a

4b6b1a974213   python  "bash" 3 days ago   Up 40 minutes    trusty_allen

This will show us a list of all of our containers, including their IDs, images, commands, and status.

Next, let’s assume that we want to add a volume to the container with ID 4b6b1a974213. To do this, we first need to create a new image based on the existing container. We can do this using the docker commit command:

$ docker commit 4b6b1a974213 python_pandas_stats

This will create a new image called python_pandas_stats based on the container with an ID 4b6b1a974213. We can now use this image to run a new container with a…
