Error "DContainer matching query does not exist."

Rock-ons
1

Hi,

Im trying to build a nextcloud rock-on based on this docker container: https://hub.docker.com/r/wonderfall/nextcloud/ with mariadb. I wrote a nextcloud.json (see below) file and saved it in “/opt/rockstor/rockons-metastore/” directoy. When I hit “Update” in the rock-on web ui I get the follwing error. What is wrong with my json-file?

Errors occurred while processing updates for following Rock-ons. Nextcloud: DContainer matching query does not exist.

Traceback (most recent call last):

I found the error: In the “container_links” section i tried to add a link for the owncloud container instead of the nextcloud container (copy paste). The error message could be better though.

@Tschaul Welcome to Rockstor. Well done on getting your Rock-on sorted.

Do you fancy submitting your working Rock-on to the Rockon-registry as a pull request. It would seem like a nice addition and we even have an open issue with 3 contributor’s comments already:

I plan to submit it once its running. Unfortunately i didn’t manage to get it running yet. Mostly because of permission problems. I decided to get my server operational with the owncloud-official rock-on first. I also need some other rock-ons that are not on the registry like tiny-tiny-rss and lychee. I will start with building these first because they seam easier. Then i will get back to the nextcloud rock-on when i understand more about docker and rock-ons :slight_smile:

@Tschaul Turns out that the current version of Rockstor does not allow to use environment section on linked containers. Here is the modified version with hardcoded mysql info. I also forked the wonderfall/nextcloud to add SSL and Let’s Encrypt support.
