Understanding Volume Mounts

[ndanyluk]

Hi, I'm trying to get Nextcloud set up with some existing PVCs. Unfortunately, I can't seem to wrap my head around how the data is structured on the pvc. My prior NC install had everything in /var/www/nextcloud/.

From what I understand the NC chart creates this:
NC main PVC -> /var/www/
NC data PVC -> /var/www/html/data

Here's where I get confused:

• NC data persistence puts data a folder called "data" at the root of the PVC path, i.e. /my/folder/on/host/data/[stuff goes here] gets mounted to /var/www/html/data[stuff goes here]
• NC main PVC doesn't seem to follow this. it's getting mounted to /var/www/ instead of the expected /var/www/html, and seems to expect the config to be placed at /var/www/config and the rest of the files within /var/www/html?

How should I be configuring this?

Sorry for the delay, @ndanyluk! 🙏

You are correct, you can use two separate PVCs for "main" and "data", but you don't have to! :) You can disable the separate PVC for data and just use one PVC with:

persistence:
  nextcloudData:
    enabled: false

NC data persistence puts data a folder called "data" at the root of the PVC path, i.e. /my/folder/on/host/data/[stuff goes here] gets mounted to /var/www/html/data[stuff goes here]

yep, that's correct, although I do kind of agree that it is a little confusing 🤔 because I am currently using the persistence.nextcloudData.enabled = false like mentioned above, and it results in an empty /var/www/html/data directory, but a /data directory that actually contains stuff like this:

root@machine /var/lib/rancher/k3s/storage/pvc-123456_nextcloud_nextcloud-files # ls
config  custom_apps  data  html  root  themes  tmp

root@machine /var/lib/rancher/k3s/storage/pvc-123456_nextcloud_nextcloud-files# ls data/
appdata_ock4vq5tff9l  audit.log  files_external  index.html appdata_ocprwvfxi7k4  __groupfolders  jessebot

root@machine /var/lib/rancher/k3s/storage/pvc-123456_nextcloud_nextcloud-files# ls -hal html/data/
total 8.0K
drwxr-xr-x  2 root     root     4.0K Jul  1 15:08 .
drwxrwxrwx 15 www-data www-data 4.0K Jul  1 15:08 ..

NC main PVC doesn't seem to follow this. it's getting mounted to /var/www/ instead of the expected /var/www/html, and seems to expect the config to be placed at /var/www/config and the rest of the files within /var/www/html?

yes, that's also correct. The configs should be automatically created as k8s ConfigMaps based on what values are provided for:

• nextcloud.phpConfigs
• nextcloud.defaultConfigs
• nextcloud.configs

Then those are mounted to /var/www/config as you mentioned.

I apologize for my own confusion, but what is there something else that is unclear? I'm very happy to help further, but was it just a confirmation you were looking for? Are you trying to setup backups or perform any other task that I can help with?
