linuxserver/nextcloud

Nextcloud gives you access to all your files wherever you are.

Where are your photos and documents? With Nextcloud you pick a server of your choice, at home, in a data center or at a provider. And that is where your files will be. Nextcloud runs on that server, protecting your data and giving you access from your desktop or mobile devices. Through Nextcloud you also access, sync and share your existing data on that FTP drive at the office, a Dropbox or a NAS you have at home.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling linuxserver/nextcloud should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Usage

Here are some example snippets to help you get started creating a container from this image.

docker

docker create \
  --name=nextcloud \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 443:443 \
  -v /path/to/appdata:/config \
  -v /path/to/data:/data \
  --restart unless-stopped \
  linuxserver/nextcloud

docker-compose

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  nextcloud:
    image: linuxserver/nextcloud
    container_name: nextcloud
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - /path/to/appdata:/config
      - /path/to/data:/data
    ports:
      - 443:443
    restart: unless-stopped

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Parameter	Function
443	WebUI

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=Europe/London	Specify a timezone to use EG Europe/London.

Volume Mappings (-v)

Volume	Function
/config	Nextcloud configs.
/data	Your personal data.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Application Setup

Access the webui at https://<your-ip>:443, for more information check out Nextcloud.

Docker image update and recreation of container alone won't update nextcloud version.

In order to update nextcloud version, you have two options, firstly make sure you are using the latest docker image,then either

1. Perform the in app gui update.
2. Use the CLI version by running docker exec -it nextcloud updater.phar (Both of these are described here)

Note: Both occ and updater.phar can be run without prepending with sudo -u abc php or sudo -u www-data php

If you are not customizing our default nginx configuration you will need to remove the file:

/config/nginx/site-confs/default

Then restart the container to replace it with the latest one.

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) can be accessed via the dynamic badge above.

Support Info

• Shell access whilst the container is running:
  • docker exec -it nextcloud /bin/bash
• To monitor the logs of the container in realtime:
  • docker logs -f nextcloud
• Container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' nextcloud
• Image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/nextcloud
