I am currently learning more about docker on how to use it at development and production.
Recently I just worked through the docker docs and some other tutorial stuff on the internet and was always looking at what is happening on my machine to understand what happens.
I know have no more running or stopped containers - the output of
docker ps -a is empty.
I now have a look at
docker volume ls and can see many volumes with a driver type local.
I have two questions now regarding this:
1) Are those the volume containers that were used by an earlier run container and shouldn't those be removed after i removed the container? Most of the time I ran the container without a specific volume but some of those created their own volume with the
2) How can I know that I can safeley delete such a volume if these aren't removed when I remove the container they belonged to.
Thanks for helping out.
