Traefik v2 HTTPS SSL Localhost

This project provides a Docker Compose template for setting up Traefik v2 with HTTPS and SSL support for localhost. It also includes an example template for setting up multiple Postgres connections.

Setup

To get started, create a Docker network using the following command:

# Create a Docker network
docker network create traefik

You will also need to generate SSL certificates for the domain "docker.localhost" and "domain.local" along with their sub-domains. You can use mkcert to generate the certificates. Install mkcert using the command mkcert -install and then generate the certificates using the following command:

# Generate certificates
mkcert -cert-file certs/local-cert.pem -key-file certs/local-key.pem "localhost" "*.localhost" "localhost"

Make sure to place the generated certificates in the certs directory of this project.

Multiple Postgres Connections

You can use the provided Docker Compose template to set up multiple Postgres connections. Here's an example template for the Postgres service:

services:
  db:
    hostname: ${POSTGRES_HOST}
    image: postgres:12.0-alpine
    restart: unless-stopped
  
    environment:
      POSTGRES_USER: ${POSTGRES_USER:-user}
      POSTGRES_PASSWORD: ${POSTGRES_PASSWORD:-changeme}
      POSTGRES_DB: ${POSTGRES_DB:-db}

    labels:
      - traefik.enable=true
      - traefik.tcp.routers.postgres.tls=true
      - traefik.tcp.routers.postgres.rule=HostSNI(`${DB_HOST}`)
      - traefik.tcp.routers.postgres.entrypoints=postgres
      - traefik.tcp.services.postgres.loadbalancer.server.port=5432
  
    expose:
      - 5432

    networks:
      - traefik

This template sets up a Postgres service with Traefik labels for enabling HTTPS, SSL, and routing based on the Host SNI (Server Name Indication) header. It also exposes port 5432 and connects to the traefik Docker network.

Don't forget to add the $POSTGRES_HOST to your /etc/hosts file.
