Ask Question. Asked 4 years, 8 months ago. So volumes are a really powerful technique, and really come into their own when your container needs to store data that needs to live beyond the lifetime of the container. And that can be done by creating your own dockerfile. This is about the simplest sort of dockerfile you can create:. With our dockerfile in place, we need to build an image with the docker build command, giving it a name I chose datatest4:v1 , and then we can create a container from that image with docker run , just as we did before.

The great thing about this approach is that now we have an image of our website that we can deploy anywhere. Technique 1: Edit in the Container The first technique is the least practical, but demonstrates a very powerful feature of Docker containers. So while our datatest1 container is running IIS, we can also run PowerShell in it like this: docker exec -it datatest1 powershell This gives us an interactive command prompt inside our container. So we can create our own index.

Technique 2: Copy into a Container The second technique is to use the docker cp command. For example, here is a running container, id is dda5fc , later we will copy files from and to this container. S The docker cp command works similar to the SSH scp command.

As more of our applications are deployed to cloud environments, working with Docker is becoming a necessary skill for developers. Often when debugging applications, it is useful to copy files into or out of our Docker containers. In this tutorial, we'll look at some different ways we can copy files to and from Docker containers. The quickest way to copy files to and from a Docker container is to use the docker cp command. This command closely mimics the Unix cp command and has the following syntax:.

Before we look at some examples of this command, let's assume we have the following Docker containers running:. We can also copy an entire directory instead of single files. The docker cp command does have some limitations. First, we cannot use it to copy between two containers. It can only be used to copy files between the host system and a single container. Second, while it does have the same syntax as the Unix cp command, it does not support the same flags.

In fact, it only supports two:. Another way to copy files to and from Docker containers is to use a volume mount.
