Traefik Let's Encrypt & Docker

Networking

$ docker network create web

Start the traefik

Now, let's create a directory on the server where we will configure the rest of Traefik:

$ mkdir -p /opt/traefik
$ cp traefik/docker-compose.yml /opt/traefik/
$ cp traefik/traefik.toml /opt/traefik/
$ touch /opt/traefik/acme.json && chmod 600 /opt/traefik/acme.json

Run the traefik service

$ cd /opt/traefik && docker-compos up -d

Start golang appa service

replace the following host name in docker-compose.yml

- "traefik.basic.frontend.rule=Host:demo1.ggz.tw"
- "traefik.basic.frontend.rule=Host:demo2.ggz.tw"

and start the app service

$ docker-compose up -d

Test your app

$ curl -v https://demo1.ggz.tw
