persistent data hint

[dmnc-net]

Hi, I never worked with docker before so you may find me very confused, please be patient.

I'm running docker for testing/dev purposes on my Arch Linux laptop and I'm following the Portainer docs, so I did this:

$ docker volume create portainer_data
$ docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

Next, in the Persist Portainer data section I'm confused with "You’ll need to persist Portainer data to keep your changes after restart/upgrade of the Portainer container". But I don't want do a bind mount, I've created the volume which is located in /var/lib/docker/volumes/portainer_data. What do you mean by restart of the Portainer container? That means that docker will delete/recreate the volume every time when the service will be started/restarted (i.e. laptop reboot)? This makes on sense to me. Thanks for clarifying

Hi @dmnc-net

Following the instructions in the quick start section will create a Docker volume and persist the Portainer data inside the volume.

The instruction in the Persist Portainer data section simply shows an example on how to persist Portainer data via a bind mount.

What could we change to make it clearer?

I also got confused after reading the guide. I think it needs a little info when persiting via volume is enough and when persisting via a bind mount is better.

Sorry for commenting on this, but to me it wasn't clear that the data was going to be persisted when created using the command in the quick start section. I found the persist section after I launched the container. By finding this I was certain that my data was going to still be there on a reboot.
