# Deployment using Docker

Using Docker is the most easy and recommended way to run PsiTransfer. There is an 
[official Container](https://hub.docker.com/r/psitrax/psitransfer/) which is 
updated whenever a GitHub push occurs.

```bash
docker run -d -v $PWD/data:/data -p 3000:3000 psitrax/psitransfer
```
The above command starts the PsiTransfer Docker container and 
 * `-d` puts the process into background (daemon mode)
 * `-v` mounts the data volume into the container
 * `-p` forwards the traffic from port 3000 into the container

**Protipp**: There are several [container tags](https://hub.docker.com/r/psitrax/psitransfer/tags/)
if you want to use a specific version. E.g. `1` is always the latest stable `1.x.x` and `1.1`
correlates with `1.1.x`.

If you want to customize some PsiTransfer configurations use environment parameters
by adding `-e` flags to the `docker run` command.

```bash
docker run -v $PWD/data:/data -p 3000:8080 \
  -e PSITRANSFER_PORT=8080 \
  -e PSITRANSFER_DEFAULTRETENTION=3600 \
  psitrax/psitransfer
```

**Protipp**: By adding `--restart always` Docker will autostart the container after reboots.
