Error deploying Chirpstack V4 portainer stack - mosquitto.conf can't mount #8

Closed Aweptimum closed 5 months ago

Aweptimum commented 5 months ago

In creating the chirpstack v4 image available in portainer, the process errors out when trying to start the mosquitto container. I've copied a portion of the event log below, but the full one (with really bad formatting, sorry) is here: https://pastebin.com/L9V9xe0E

                Check if the specified host path exists and is the expected type

I can confirm the config file is on the host at the expected path: image

/data/compose/4/Stack/ChirpStack4/configuration/mosquitto/mosquitto.conf

So for some reason it isn't mounting to the image, and I can't find much helpful info for fixing this error. It's usually caused by accidentally mapping a directory to a file or entering an incorrect host path (docker will just implicitly create a folder), but neither seems to be the case here. Anyone got any ideas?

Hi @Aweptimum , that stack mounts a local file to configure the mosquitto service. AFAIK this is not supported by Portainer CE, correct me if I'm wrong. I'd suggest to use rakpios-cli or use docker container directly on the stack folder to bring it up.

Sorry for the long silence (life got busy)

I haven't used portainer before, so your guess is better than mine. Both the cli tool and docker compose worked just fine. I was able to access the chirpstack web interface and ensure everything worked. Probably can close, but it would be nice if Portainer CE's lack of local mounting was confirmed and then added to the Portainer Services Documentation

You are right. Will add a notice to the documentation about it. Closing the issue.

Aweptimum commented 5 months ago

Cool, thanks :)

Actually, I have already pushed a change to the stack that solves the issue. Since named volumes work just fine with Portainer I bring up an initial service to copy the configurations to one such named volume shared with the rest of services, hence they can access the configuration data.
