# Install from scratch.

This is a tiny guide to install cryptgeon on (probably) any unix system (and maybe windows?) from scratch using traefik as the proxy, which will manage certificates and handle https for us.

1. Install Docker & Docker Compose.
2. Install Traefik.
3. Run the cryptgeon.

## Install Docker & DOcker Compose

- [Docker](https://docs.docker.com/engine/install/)
- [Compose](https://docs.docker.com/compose/install/)

## Install Traefik 2.0

```sh
/foo/bar/traefik/
├── docker-compose.yaml
└── traefik.yaml
```

```yaml
# docker-compose.yaml

version: '3.8'
services:
  traefik:
    image: traefik:2.6
    restart: unless-stopped
    ports:
      - '80:80'
      - '443:443'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./traefik.yaml:/etc/traefik/traefik.yaml:ro
      - ./data:/data
    labels:
      - 'traefik.enable=true'

      # HTTP to HTTPS redirection
      - 'traefik.http.routers.http_catchall.rule=HostRegexp(`{any:.+}`)'
      - 'traefik.http.routers.http_catchall.entrypoints=insecure'
      - 'traefik.http.routers.http_catchall.middlewares=https_redirect'
      - 'traefik.http.middlewares.https_redirect.redirectscheme.scheme=https'
      - 'traefik.http.middlewares.https_redirect.redirectscheme.permanent=true'

networks:
  default:
    external: true
    name: proxy
```

```yaml
# traefik.yaml

api:
  dashboard: true

# Define HTTP and HTTPS entrypoint
entryPoints:
  insecure:
    address: ':80'
  secure:
    address: ':443'

# Dynamic configuration will come from docker labels
providers:
  docker:
    endpoint: 'unix:///var/run/docker.sock'
    network: 'proxy'
    exposedByDefault: false

# Enable acme with http file challenge
certificatesResolvers:
  le:
    acme:
      email: me@example.org
      storage: /data/acme.json
      httpChallenge:
        entryPoint: insecure
```

**Run**

```sh
docker network create proxy
docker-compose up -d
```

## Cryptgeon

Create another docker-compose.yaml file in another folder.

```sh
/foo/bar/cryptgeon/
└── docker-compose.yaml
```

```yaml
version: '3.8'

networks:
  proxy:
    external: true

services:
  memcached:
    image: memcached:1-alpine
    restart: unless-stopped
    entrypoint: memcached -m 256M -I 4M # Limit to 128 MB Ram, customize at free will.

  app:
    image: cupcakearmy/cryptgeon:latest
    restart: unless-stopped
    depends_on:
      - memcached
    environment:
      SIZE_LIMIT: 4 MiB
    networks:
      - default
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.cryptgeon.rule=Host(`cryptgeon.example.org`)
      - traefik.http.routers.cryptgeon.entrypoints=secure
      - traefik.http.routers.cryptgeon.tls.certresolver=le
```

**Run**

```sh
docker-compose up -d
```
