[Nextcloud](https://nextcloud.com/) 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](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/). 

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 | arm32v6-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=1001 \
  -e PGID=1001 \
  -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.

```yaml
---
version: "2"
services:
  nextcloud:
    image: linuxserver/nextcloud
    container_name: nextcloud
    environment:
      - PUID=1001
      - PGID=1001
      - TZ=Europe/London
    volumes:
      - </path/to/appdata>:/config
      - <path/to/data>:/data
    ports:
      - 443:443
    mem_limit: 4096m
    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=1001` | for UserID - see below for explanation |
| `PGID=1001` | 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. |



## 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=1001` and `PGID=1001`, to find yours use `id user` as below:

```
  $ id username
    uid=1001(dockeruser) gid=1001(dockergroup) groups=1001(dockergroup)
```

## Application Setup

Access the webui at `<your-ip>:443`, for more information check out [Nextcloud][appurl].

Please note you will need a MySQL/MariaDB or other backend database to set this up.  Also please look [here](https://docs.nextcloud.com/server/11/admin_manual/installation/system_requirements.html#database-requirements-for-mysql-mariadb) for how to configure your database with regard to binlog format and installation.

If updating to nextcloud 12 you will need to comment out line `add_header X-Frame-Options "SAMEORIGIN";` in the file /config/nginx/site-confs/default
