# Docker guide

You can quickly get a server running using Docker. You need to have
[docker](https://www.docker.com/community-edition) and
[docker-compose](https://docs.docker.com/compose/install/) installed.

## Production

### Build your own Docker image

```bash
$ git clone https://github.com/chocobozzz/PeerTube /tmp/peertube
$ cd /tmp/peertube
$ docker build . -f ./support/docker/production/Dockerfile.stretch
```

### Run a preconfigured setup with all dependencies

PeerTube needs a PostgreSQL and a Redis instance to work correctly. If you want
to quickly set up a full environment, either for trying the service or in
production, you can use a `docker-compose` setup.

```bash
$ git clone https://github.com/chocobozzz/PeerTube /tmp/peertube
$ cd /tmp/peertube/support/docker/production
```

Then tweak the `docker-compose.yml` file there according to your needs. Then
you can use the regular `up` command to set it up, with possible overrides of
the environment variables:

```bash
$ PEERTUBE_HOSTNAME=peertube.lvh.me \
  PEERTUBE_ADMIN_EMAIL=test@example.com \
  PEERTUBE_TRANSCODING_ENABLED=true \
  PEERTUBE_SIGNUP_ENABLED=true \
  PEERTUBE_SMTP_HOST=mail.lvh.me \
  PEERTUBE_SMTP_PORT=1025 \
  PEERTUBE_SMTP_FROM=noreply@peertube.lvh.me \
    docker-compose up
```

Other environment variables are used in
`support/docker/production/config/custom-environment-variables.yaml` and can be
intuited from usage.

For this example configuration, a reverse proxy is quite recommended. The
example Docker Compose file provides example labels for a Traefik load
balancer, although any HTTP reverse proxy will work fine. See the example
Nginx configuration `support/nginx/peertube` file to get an idea of
recommendations and requirements to run PeerTube the most efficiently.

When starting the containers for the first time, you will get permissions errors for the data volume, like this one:

```
Error: EACCES: permission denied, mkdir '/data/logs'
```

The peertube user inside the container has a UID and GID of 991 so you have to change the folder's owner, in the case you're using `./data`:

```
chown -R 991:991 data/
```

**Important**: note that you'll get the initial `root` user password from the
program output, so check out your logs to find them.

## Development

The Docker image that's preconfigured in `support/docker/dev` contains all the
services embedded in one image, so as to work correctly on
[Janitor](https://janitor.technology). It is much not advised to use it in
production.
