Traefik App runner

README.md

Setup

Image

• Create an ecr registry called mytraefik
• Update app1 and app2 server urls in dynamic_conf.yml to point to other apprunner urls you already have
• Update .example.com usage in dynamic_conf.yml to a domain you have and will link to
• Build image locally docker image build -t mytraefik:latest .
• Tag image docker tag mytraefik:latest <yourawsaccount>.dkr.ecr.us-east-1.amazonaws.com/mytraefik:latest
• Push image to ecr docker push <yourawsaccount>.dkr.ecr.us-east-1.amazonaws.com/mytraefik:latest

Apprunner

• Create a new app in apprunner called mytraefik
• Make sure port 80 is set
• Link a custom domain the same one you use in the dynamic_conf.yml config and enter as a wildcard e.g *.example.com

Once deployed you should be able to visit app1.example.com and app2.example.com but have the apprunner containers you already have be served to you
