In this post we’ll look at how to Install NextCloud on a Raspberry Pi 4 with OpenMediaVault and Docker.
We’re going to use the setup from https://hub.docker.com/_/nextcloud, but we’re going to change one thing: the database.
The database that is being used in the docker-compose file on the site isn’t compatible with ARM processors, so we’ll need to change that in a bit.
But first, we need to get logged in to our Raspberry Pi’s Portainer. This tutorial assumes that you already have Docker and Portainer installed, most likely via OpenMediaVault.
- You’ll need a domain name.
- You’ll need to a CloudFlare account with your domain name pointed to it.
- You’ll need to point a subdomain to your home’s IP address. Make sure that Proxy Status is “DNS Only”. Also make sure that you change SSL/TLS to “Full”.
- You’ll need to forward ports 80 and 443 to your Raspberry Pi.
- You’ll need NGINX Proxy Manager installed.
- You’ll need to create a volume in OpenMediaVault for your NextCloud file storage.
Open Portainer on your Raspberry Pi and create a new Stack.
Paste the following into your new stack:
version: '2' volumes: nextcloud: db: services: db: image: yobasystems/alpine-mariadb:latest command: --transaction-isolation=READ-COMMITTED --binlog-format=ROW restart: always volumes: - db:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD=password #Change This - MYSQL_PASSWORD=password #Change This - MYSQL_DATABASE=nextcloud - MYSQL_USER=nextcloud app: image: nextcloud ports: - 8080:80 links: - db volumes: - nextcloud:/var/www/html #Change 'nextcloud' to your external drive volume if available restart: always
Change the few things as noted above.
Click the “Deploy the Stack” button.
Next, go to your NGINX Proxy Manager dashboard. Create a new Proxy Host.
- Fill in the domain name (or subdomain) you designated for your NextCloud install.
- Scheme should be http.
- Forward Hostname/IP should be your Raspberry Pi’s IP address.
- Foward port should be 8080.
- Click the “Block Common Exploits” toggle.
Go to the SSL tab.
- Change “None” to “Request a New SSL Certificate”.
- Click the “Force SSL” and “HTTP/2 Support” toggles.
- You can click the HSTS toggles if you’ve enabled HSTS in CloudFlare.
- Click “Save”.
After a moment, you should see that everything has deployed correctly.
Next, go to https://nextcloud.yourdomain.com (change this to your actual domain) and you should see the NextCloud install page.
- Enter an Admin username and password.
- Change the database type to MySQL/MariaDB.
- Enter the username, password, and database name as you have them in your Portainer Stack.
- Change Database location to from “localhost” to “db” (without quotes).
- Toggle the option for additional app installation to meet your needs.
- Click “Finish setup”.
At this point, you can go get some lunch or something as the install process will take a while since we’re on a 4 core ARM processor.
Once the install is complete, you’ll be taken to the NextCloud dashboard and then you should be good to go!
