caddy to serve hasura

The greatest adventage of using Caddy is because it automates the SSL certificate generation and renewal:

docker-compose.yaml:

version: "3.6"
services:
  postgres:
    image: postgres:12
    restart: always
    volumes:
      - db_data:/var/lib/postgresql/data
    environment:
      POSTGRES_PASSWORD: postgrespassword
  graphql-engine:
    image: hasura/graphql-engine:v1.1.1
    depends_on:
      - "postgres"
    restart: always
    environment:
      # database url to connect
      HASURA_GRAPHQL_DATABASE_URL: postgres://postgres:postgrespassword@postgres:5432/postgres
      # enable the console served by server
      HASURA_GRAPHQL_ENABLE_CONSOLE: "true" # set "false" to disable console
      ## uncomment next line to set an admin secret key
      HASURA_GRAPHQL_ADMIN_SECRET: secret
    command:
      - graphql-engine
      - serve
  caddy:
    image: abiosoft/caddy:0.11.0
    depends_on:
      - "graphql-engine"
    restart: always
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - ./Caddyfile:/etc/Caddyfile
      - caddy_certs:/root/.caddy
volumes:
  db_data:
  caddy_certs:

Caddyfile:

# replace :80 with your domain name to get automatic https via LetsEncrypt
:80  {
    proxy / graphql-engine:8080 {

    }
