⁠Introduction

Dockerfile to create a Docker⁠ container image for Nextcloud⁠.

Nextcloud is a self-hosted open source application for file hosting and sharing.

⁠Contributing

If you find this image useful here's how you can help:

• Send a pull request with your awesome features and bug fixes
• Help users resolve their issues⁠.
• Support the development of this image with a donation⁠

⁠Issues

Before reporting your issue please try updating Docker to the latest version and check if it resolves the issue. Refer to the Docker installation guide⁠ for instructions.

SELinux users should try disabling SELinux using the command setenforce 0 to see if it resolves the issue.

If the above recommendations do not help then report your issue⁠ along with the following information:

• Output of the docker version and docker info commands
• The docker run command or docker-compose.yml used to start the image. Mask out the sensitive bits.
• Please state if you are using Boot2Docker⁠, VirtualBox⁠, etc.

⁠Getting started

⁠Installation

Automated builds of the image are available on Dockerhub⁠ and is the recommended method of installation.

docker pull sameersbn/nextcloud:18.0.2

Alternatively you can build the image yourself.

docker build -t sameersbn/nextcloud github.com/sameersbn/docker-nextcloud

⁠Quickstart

The quickest way to start using this image is with docker-compose⁠.

wget https://raw.githubusercontent.com/sameersbn/docker-nextcloud/master/docker-compose.yml

Update the NEXTCLOUD_URL environment variable in the docker-compose.yml file with the url from which Nextcloud will be externally accessible.

docker-compose up

Alternatively, you can start Nextcloud manually using the Docker command line.

Step 1. Launch a PostgreSQL container

docker run --name nextcloud-postgresql -itd --restart=always \
  --env 'DB_NAME=nextcloud_db' \
  --env 'DB_USER=nextcloud' --env 'DB_PASS=password' \
  --volume /srv/docker/nextcloud/postgresql:/var/lib/postgresql \
  sameersbn/postgresql:9.6-2

Step 2. Launch the Nextcloud php-fpm container

docker run --name nextcloud -itd --restart=always \
  --env NEXTCLOUD_URL=http://cloud.example.com:10080 \
  --link nextcloud-postgresql:postgresql \
  --volume /srv/docker/nextcloud/nextcloud:/var/lib/nextcloud \
  sameersbn/nextcloud:18.0.2 app:nextcloud

Step 3. Launch a NGINX frontend container

docker run --name nextcloud-nginx -itd --restart=always \
  --link nextcloud:php-fpm \
  --publish 10080:80 \
  sameersbn/nextcloud:18.0.2 app:nginx

Point your browser to http://cloud.example.com:10080 and login using the default username and password:

• username: admin
• password: password

⁠Persistence

For Nextcloud to preserve its state across container shutdown and startup you should mount a volume at /var/lib/nextcloud.

SELinux users should update the security context of the host mountpoint so that it plays nicely with Docker:

mkdir -p /srv/docker/nextcloud
chcon -Rt svirt_sandbox_file_t /srv/docker/nextcloud

⁠Maintenance

⁠Creating backups

The image allows users to create backups of the Nextcloud installation using the app:backup:create command or the nextcloud-backup-create helper script. The generated backup consists of configuration files, uploaded files and the sql database.

Before generating a backup — stop and remove the running instance.

docker stop nextcloud && docker rm nextcloud

Relaunch the container with the app:backup:create argument.

docker run --name nextcloud -it --rm [OPTIONS] \
  sameersbn/nextcloud:18.0.2 app:backup:create

The backup will be created in the backups/ folder of the Persistent⁠ volume. You can change the location using the NEXTCLOUD_BACKUPS_DIR configuration parameter.

By default backups are held indefinitely. Using the NEXTCLOUD_BACKUPS_EXPIRY parameter you can configure how long (in seconds) you wish to keep the backups. For example, setting NEXTCLOUD_BACKUPS_EXPIRY=604800 will remove backups that are older than 7 days. Old backups are only removed when creating a new backup, never automatically.

⁠Restoring Backups

Backups created using instructions from the Creating backups⁠ section can be restored using the app:backup:restore argument.

Before restoring a backup — stop and remove the running instance.

docker stop nextcloud && docker rm nextcloud

Relaunch the container with the app:backup:restore argument. Ensure you launch the container in the interactive mode -it.

docker run --name nextcloud -it --rm [OPTIONS] \
  sameersbn/nextcloud:18.0.2 app:backup:restore

A list of existing backups will be displayed. Select a backup you wish to restore.

To avoid this interaction you can specify the backup filename using the BACKUP argument to app:backup:restore, eg.

docker run --name nextcloud -it --rm [OPTIONS] \
  sameersbn/nextcloud:18.0.2 app:backup:restore BACKUP=1417624827_nextcloud_backup.tar

⁠Upgrading

To upgrade to newer releases:

1. Download the updated Docker image:

docker pull sameersbn/nextcloud:18.0.2

1. Stop the currently running image:

docker stop nextcloud

1. Remove the stopped container

docker rm -v nextcloud

1. Start the updated image

docker run -name nextcloud -itd \
  [OPTIONS] \
  sameersbn/nextcloud:18.0.2

⁠Shell Access

For debugging and maintenance purposes you may want access the containers shell. If you are using Docker version 1.3.0 or higher you can access a running containers shell by starting bash using docker exec:

docker exec -it nextcloud bash
