Ultimately, there are a myriad of ways to deploy web apps, but this is the toolkit we're using at [37signals](https://37signals.com) to bring [HEY](https://www.hey.com) [home from the cloud](https://world.hey.com/dhh/why-we-re-leaving-the-cloud-654b47e0) without losing the advantages of modern containerization tooling.
## Running MRSK from Docker
MRSK is packaged up in a Docker container similarly to [rails/docked](https://github.com/rails/docked). This will allow you to run MRSK (from your application directory) without having to install any dependencies other than Docker. Add the following alias to your profile configuration to make working with the container more convenient:
```bash
alias mrsk="docker run -it --rm -v '${PWD}:/workdir' -v '${SSH_AUTH_SOCK}:/ssh-agent' -v /var/run/docker.sock:/var/run/docker.sock -e 'SSH_AUTH_SOCK=/ssh-agent' ghcr.io/mrsked/mrsk:latest"
```
Since MRSK uses SSH to establish a remote connection, it will need access to your SSH agent. The above command uses a volume mount to make it available inside the container and configures the SSH agent inside the container to make use of it.
## Configuration

### MRSK env variables
The following env variables are set when your container runs:
`MRSK_CONTAINER_NAME` : this contains the current container name and version
### Using different roles for servers

You can specialize the default Traefik rules by setting labels on the containers that are being started:
```
```yaml
labels:
traefik.http.routers.hey.rule: Host(\`app.hey.com\`)
traefik.http.routers.hey.rule: Host(`app.hey.com`)
```
Note: The escaped backticks are needed to ensure the rule is passed in correctly and not treated as command substitution by Bash!
Note: The backticks are needed to ensure the rule is passed in correctly and not treated as command substitution by Bash!
This allows you to run multiple applications on the same server sharing the same Traefik instance and port.
