# Installing with Docker

ownCloud can be installed using Docker, using the official ownCloud Docker image. This official image is designed to work with a data volume in the host filesystem and with separate MariaDB and Redis containers. The configuration:

- exposes ports 80 and 443, allowing for HTTP and HTTPS connections.
- mounts the data and MySQL data directories on the host for persistent storage.

## Installation on a Local Machine

To use it, first create a new project directory and download `docker-compose.yml` from the ownCloud Docker GitHub repository into that new directory. Next, create a .env configuration file, which contains the required configuration settings. Only a few settings are required, these are:

Setting Name | Description | Example
--- | --- | ---
`VERSION` | The ownCloud version | `latest`
`DOMAIN` | The ownCloud domain | `localhost`
`ADMIN_USERNAME` | The admin username | `admin`
`ADMIN_PASSWORD` | The admin user’s password | `admin`
`HTTP_PORT` | The HTTP port to bind to | `80`
`HTTPS_PORT` | The HTTP port to bind to | `443`

Then, you can start the container, using your preferred Docker command-line tool. The example below shows how to use Docker Compose.

Note

You can find instructions for using plain docker in the GitHub repository.

    # Create a new project directory
    mkdir owncloud-docker-server

    cd owncloud-docker-server

    # Copy docker-compose.yml from the GitHub repository
    wget https://raw.githubusercontent.com/owncloud-docker/server/master/docker-compose.yml

    # Create the environment configuration file
    cat << EOF > .env
    VERSION=10.0.4
    DOMAIN=localhost
    ADMIN_USERNAME=admin
    ADMIN_PASSWORD=admin
    HTTP_PORT=80
    HTTPS_PORT=443
    EOF

    # Build and start the container
    docker-compose up -d

When the process completes, then check that all the containers have successfully started, by running `docker-compose ps`. If they are all working correctly, you should expect to see output similar to that below:

             Name                     Command               State                     Ports
    -------------------------------------------------------------------------------------------------------
    server_db_1         /usr/bin/entrypoint /bin/s ...   Up      3306/tcp
    server_owncloud_1   /usr/local/bin/entrypoint  ...   Up      0.0.0.0:443->443/tcp, 0.0.0.0:80->80/tcp
    server_redis_1      /bin/s6-svscan /etc/s6           Up      6379/tcp

In it, you can see that the database, ownCloud, and Redis containers are running, and that ownCloud is accessible via ports 443 and 8080 on the host machine.

Note

Just because all the containers are running, it takes a few minutes for ownCloud to be fully functional. If you run `docker-compose logs --follow owncloud` and see a significant amount of information logging to the console, then please wait until it slows down to attempt to access the web UI.

### Logging In

To log in to the ownCloud UI, open `https://localhost` in your browser of choice, where you see the standard ownCloud login screen, as in the image below.

The username and password are the admin username and password which you stored in `.env` earlier.

Note

The first time that you access the login page via HTTPS, a browser warning appears, as the SSL certificate in the Docker setup is self-signed. However, the self-signed certificate can be overwritten with a valid cert, within the host volume.

### Stopping the Containers

Assuming you used docker-compose, as in the previous example, to stop the containers use `docker-compose stop`. Alternatively, use `docker-compose down` to stop and remove containers, along with the related networks, images, and volumes.

### Upgrading ownCloud on Docker

When a new version of ownCloud gets released, you should update your instance. To do so, follow these simple steps.

First, go to your docker directory where your `.yaml` or `.env` file exists. Second, put ownCloud into maintenance mode; you can do so using the following command:

    docker-compose exec server occ maintenance:mode --on

Third, create a backup in case something goes wrong during the upgrade process, using the following command:

    docker-compose exec db backup

Note

This assumes that you are using the default database container from Webhippie.

Fifth, shutdown the containers.

    docker-compose down

Sixth, update the version number of ownCloud in your `.env` file or the YAML file. You can use sed for it, as in the following example.

    # Make sure that you adjust the example to match your installation.
    sed -i 's/^owncloud_version=.*$/owncloud_version=<newVersion>/' /compose/*/.env

Seventh, view the file to ensure the changes has been implemented.

>     cat .env

Eighth, start your docker instance again.

    docker-compose up -d

Now you should have the current ownCloud running with docker-compose.
