Docker Volume

If you copy or create a file in a container when you stop that container that file or the other files we created or copied will be deleted.Solution for this is using Docker Volume.

There are 4 commands that we will work with them:

• docker volume ls
• docker volume create
• docker volume inspect
• docker volume rm

we start with docker volume create:

docker volume create --name data

Now if we use docker volume ls it will show the volume.

If you want to see full descriptions about a volume we can use docker volume inspect data.

There are 3 important parts in the outcome one of them is driverif you run it on a network you can mount it or its on a local host.

We need 2 directories for Docker volume:

• We saw the first one in docker volume inspect data
• The second one is where we want to save our files on it.

This command will mount a volume inside a container:

docker run --name youcanputanythinghere -d -v data:/var/data ubuntu
