[Nextcloud] Run NextCloudPi Docker with external storage

Links

NextCloudPi (Docs)
NextCloudPi on DockerHub
Current installation process (Outdated installation process, but contains some usefull information)

Installation

If you want to use the external storage app to mount an NFS share in Nextcloud, there are two ways when using Docker. Mount the NFS share directly inside the Docker container. This would be easier when the container is already up and runing. Or mount the NFS share on the Host and pass the mountpoint as an argument when creating the Docker container: -v /mnt/nfs/:/mnt/nfs/

DOMAIN=your.domain.com
docker run -ti -d -p 4443:4443 -p 443:443 -p 80:80 -v ncdata:/data -v /mnt/nfs/:/mnt/nfs/ --name nextcloudpi ownyourbits/nextcloudpi $DOMAIN --restart=unless-stopped

Now wait until you see ‘Init done’ in the logs.

docker logs -f nextcloudpi

ncdata

If you ever need direct access to your storage, you can find out where your files are located with:

docker inspect nextcloudpi

Scroll up to “Mounts” and look for the path behind “Source”.

"Source": "/var/lib/docker/volumes/ncdata/_data"

Now you still have to navigate through a few folders. I finally found my files here:

ls /var/lib/docker/volumes/ncdata/_data/nextcloud/data/ncp/files/

Update to latest NCP version

docker exec -it nextcloudpi ncp-update

[Docker] Wallabag installation

https://www.wallabag.org
https://github.com/wallabag/docker

Just replace https://your_domain with your domain.

docker run -d --name wallabag --restart=always -v /opt/wallabag/data:/var/www/wallabag/data -v /opt/wallabag/images:/var/www/wallabag/web/assets/images -p 80:80 -e SYMFONY__ENV__DOMAIN_NAME=https://your_domain -e SYMFONY__ENV__FOSUSER_REGISTRATION=false wallabag/wallabag

Check with docker ps if the docker container is successfully up and running. Now just add a new subdomain with ssl in your nginx-proxy-manager.
Default login is wallabag:wallabag.
