Nextcloud with Docker compose

This repository contains a Docker compose file which can be used to easily create a Nextcloud instance.

Architecture

Here are the various containers involved.

  • nextcloud: the actual Nextcloud server
  • mysql: the database used by Nextcloud to store its configuration
  • reverse-proxy: a nginx reverse proxy in front of Nextcloud and doing SSL termination
  • letsencrypt-companion: an utility container which issues and renews SSL certificates
  • backups: an utility container which regularly backups the Nextcloud files and database

Usage

Follow the steps below. If you don't want any backups, just remove the backups: section in docker-compose.yml, jump to step 2, and ignore the instructions related to Backblaze B2.

Step 1: Create a Backblaze account and bucket

  • Sign up for a Backblaze account at https://www.backblaze.com/b2/sign-up.html.

  • Write down your Backblaze account ID and secret key (TODO) for later

  • Create a B2 bucket (e.g. christophetd-nextcloud-backups) and write down its name for later

Step 2: Point your subdomain to the appropriate machine

  • If you don't have any, spin up a VPS on any cloud provider (AWS EC2, Digital Ocean, OVH...). If you use the following referral link, you'll benefit from $10 of free credit on Digital Ocean (and I will get $25): https://m.do.co/c/1504134cd374.

  • Point your subdomain (e.g. nextcloud.christophetd.fr) to this newly created VPS

Step 3: Configuration

Edit the .env file, and change at least the following:

  • HOST: the hostname of your VPS (e.g. nextcloud.christophetd.fr)
  • B2_BUCKET: the name of the B2 bucket you created in step 1
  • B2_ID and B2_KEY: your B2 credentials from step 1
  • BACKUP_ENCRYPTION_KEY: set it to a random passphrase. It will be used to encrypt your backups before shipping them to Backblaze.

Step 4: Profit!

Run:

$ docker-compose up -d

You'll need to wait a few minutes on first launch, as there is some certificate generation involved. Then, you should be able to access your Nextcloud instance!

You can now define your administrator credentials and use Nextcloud.
