# Nextcloud

## Running the `occ` CLI as `www-data` user

To run `occ` as the `www-data` user in the Nextcloud container:

```bash
$ POD_NAME=$(kubectl get pod -n nextcloud --selector=app.kubernetes.io/name=nextcloud -o jsonpath='{.items[0].metadata.name}')
$ kubectl exec -n nextcloud -it $POD_NAME -- bash

root@nextcloud-6d465f97c-f7tg5:/var/www/html# 
root@nextcloud-7d75b866f5-n5rnt:/var/www/html# runuser --user www-data -- bash

www-data@nextcloud-7d75b866f5-n5rnt:~/html$ php occ list

```

## Transfer ownership of files and calendars between user accounts

Sometimes a person changes institutions and needs to log in via a new identity provider. This generates a new Keycloak user account with a new ID. Transfer the old account's files and calendars to the new account using the example below:

```bash
www-data@nextcloud-6d465f97c-f7tg5:~/html$ ./occ files:transfer-ownership keycloak-old-user  keycloak-new-user
