Nextcloud using podman behind a firewall - joefidler/joefidler.github.io GitHub Wiki

Run a containerized Nextcloud behind your routers firewall using Podman. Uses Nextcloud's built-in web-server and does not support HTTPS secured sessions, but it is an quick, easier way to start getting familiar with Nextcloud. Do not expose this setup outside your network's firewall or use it for anything requiring security or high volume traffic.

Firewalld redirect ports

This is explored more here but basically we use the hosts firewall to direct port 80 to 8000. This step is optional (it's more for convenience) - if you don't want to do it simply use http://servers-ip-address:8000 when connecting to Nextcloud.

forward-ports: 
port=80:proto=tcp:toport=8000:toaddr=

Create a pod for Nextcloud and the database

podman pod create --hostname nextcloud_pod --name nextcloud_pod -p 8000:80

Create the Mariadb database

podman run --name mariadb \
--pod nextcloud_pod \
-v db:/var/lib/mysql:Z \
-e MYSQL_USER="nextcloud" \
-e MYSQL_PASSWORD="sql-password" \
-e MYSQL_ROOT_PASSWORD="sql-root-password" \
-e MYSQL_DATABASE="nextcloud" \
-d --restart=always \
docker.io/library/mariadb:latest

Create the Nextcloud instance

podman run --name nextcloud \
--pod nextcloud_pod \
-v html:/var/www/html:z \
-d --restart=always \
-e MYSQL_HOST="127.0.0.1" \
-e MYSQL_USER="nextcloud" \
-e MYSQL_PASSWORD="sql-password" \
-e MYSQL_DATABASE="nextcloud" \
docker.io/library/nextcloud:latest

Confirm all is good

podman pod list gives a list of your pods

podman ps gives a list of your active containers and their IDs

podman volume list gives a list of the podman managed volumes

podman logs CONTAINER_ID gives the logs of a container if needed

Connect to your Nextcloud

First start can take a few moments to get done. Your Nextcloud logs should show that it's "ready for connections" when it's ready.

In a browser go to http://your-server-ip-address and you should see a page to setup the admin login.

You are now ready to setup user accounts, apps and remote connect devices. Have fun !

Going forward

You can start (or stop) Nextcloud using the pod command

podman pod start nextcloud_pod

Monitoring health and activity

http://your-server-ip/settings/admin/serverinfo

Updating the Nextcloud version. When running in a version updates are normally done by updating the container image.

$ podman pull nextcloud     (defaults to latest container image)
$ podman ps                 (confirm container names or ID- I have assumed the names we used before)
$ podman stop nextcloud     (stop the container)
$ podman rm nextcloud       (scary but it's the container not the data)
$ podman run   nextcloud  - use the full command above to create the new instance
$ podman ps                 (confirm we are running again)
