- komljen 11y agoI would say that there is just a little overhead as Postgres data volume is mounted inside Docker container. Running Postgres in docker container without volumes would have a bigger impact. And Docker container is not a VM, so I don't like to use word Virtualization for containers :)
- kennu 11y agoIt would be interesting. But I would also note that Docker doesn't do virtualization. It uses e.g. mount namespaces to mount an existing Linux volume inside the container (http://man7.org/linux/man-pages/man7/namespaces.7.html http://man7.org/linux/man-pages/man7/namespaces.7.html).
