Kamal Deploy with a self signed certificate for SSL
Use Traefik's own self signed certificate feature out of the box
If you use Kamal Deploy behind a service like Cloudflare or some Load Balancer which terminates SSL, and using Let's Encrypt is not an option, you can setup Traefik to use a self signed certificate.
Simply modify the servers and traefik part of your deploy.yml as following:
1 servers:
2 web:
3 hosts:
4 - your-host
5 labels:
6 traefik.http.routers.yourservice.entrypoints: websecure
7
8 traefik:
9 options:
10 publish:
11 - "443:443"
12 args:
13 entryPoints.websecure.address: ":443"
14 entrypoints.websecure.http.tls: trueAnd now you can access your server using a https:// link (beware of the ssl error warning of your browser) OR tell Cloudflare to encrypt end-to-end, using a self signed certificate on the server.
