How to setup Caddy (with Docker)

Untested

Folders

Create the folder structure.

# Create main service directory
mkdir -p /home/dan/services

# Create the Caddy directories
mkdir -p /home/dan/services/caddy/{config,data}

Caddyfile

cd /home/dan/services
nano Caddyfile

Paste the following content:

{
    # uncomment the next line if you plan on using grafana and prometheus
    # metrics 

    log {
        # can also be format json
        format console {
            time_format iso8601
        }
    }
}

Docker

Create the Docker Compose File

nano docker-compose.yml

Paste the following content:

services:
  caddy:
    image: caddy:alpine
    restart: unless-stopped
    container_name: caddy
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile
      - ./caddy/config:/config
      - ./caddy/data:/data
    network_mode: "host"

Download and start the caddy docker service:
```
docker compose up -d caddy
```
Check if Caddy was able to start successfully.
```
docker ps
```
If something doesn't look right, you can inspect the logs:

bash docker compose logs -f caddy
