​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 lscr.io/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
Version Tags
This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.
Tag
Description
latest
Stable Nextcloud releases (currently php7)
php8
Experimental php8 based Nextcloud releases
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:
1
/config/nginx/site-confs/default
Copied!
Then restart the container to replace it with the latest one.
Collaborative Editing
Nextcloud's built-in collaborative editing packages (Collabora/CODE and OnlyOffice) only work on x86_64 systems with glibc, and therefore they are not compatible with our images. You should create separate containers for them and set them up in Nextcloud with their respective connector addons.
If (auto) installed, those built-in packages may cause instability and should be removed.
Usage
To help you get started creating a container from this image you can either use docker-compose or the docker cli.

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.
Miscellaneous Options
Parameter
Function
Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend FILE__.
As an example:
1
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Copied!
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:
1
  $ id username
2
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
Copied!
