simple local https setup for development purpose based on docker, caddy, and mkcert

• mkcert
• docker
• docker-compose

1. Install the prerequisites
2. Run mkcert install mkcert -install
3. Create new cert for your desired hostname mkcert example.com "*.example.com"

• It will generate e.g example.com+1.pem & example.com+1-key.pem
• Place it in the certs directory

4. Create Caddyfile, place it in the root of this directory alongside the docker-compose.yml

• you can use the Caddyfile.base to as a base for your config
• there is some working example in Caddyfile.sample
  • hostname = alan.dev, with app running on port 9000

5. Run docker-compose up and it's done!

• PS the container is configured to always restart so you won't need to redo this, and your https://example.com can be accessed everytime you startup your machine, make sure your app is running on the configured port!
