+# Docker Compose local HTTPS
+
+> Examples of local HTTPS with docker-compose + mkcert
+
+## Prerequisites
+
+- [mkcert](https://github.com/FiloSottile/mkcert)
+- [Docker Desktop](https://www.docker.com/products/docker-desktop)
+
+Run `mkcert -install`
+
+Run `./init.sh` (creates local certificates using mkcert and copies them to where the Caddy and nginx examples expect them)
+
+## The setup
+
+Each example has a barebones Node app running on the official Node 10 Docker image running on port 8080.
+
+The Node code is at [./caddy/app/index.js](./caddy/app/index.js) and [./nginx/app/index.js](./caddy/app/index.js).
+
+It also has a reverse-proxy set up using Caddy and nginx respectively which
+
+## Caddy Example
+
+> Caddy is the HTTP/2 web server with automatic HTTPS.
+> 
+> https://caddyserver.com/
+
+See [./caddy](./caddy), uses https://github.com/abiosoft/caddy-docker Docker image.
+
+To run it:
+
+```sh
+cd caddy
+docker-compose up
+```
+
+Then either nagivate to https://foo.test or `curl https://foo.test`.
+
+> Note: the nginx example needs to be stopped before starting the Caddy example
+
+## nginx Example
+
+> [nginx](https://www.nginx.com/) is a web server which can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.
+> 
+> Wikipedia
+
+See [./nginx](./nginx), uses https://github.com/jwilder/nginx-proxy Docker image.
+
+```sh
+cd nginx
+docker-compose up
+```
+
+Then either nagivate to https://foo.test or `curl https://foo.test`.
+
+> Note: the Caddy example needs to be stopped before starting the nginx example
