 # Apache FPM container based on phusion
 Simple apache-vhost that serves content from /var/www/web - php-requests are
 proxied to a linked fpm-container named "fpm" on port 9000.
+
+
+# Dory
+
+Use the following if you use [dory](https://github.com/FreedomBen/dory) (much of the same applies for  [nginx-proxy](https://github.com/jwilder/nginx-proxy) and [dinghy-http-proxy](https://github.com/codekitchen/dinghy-http-proxy) which Dory is based on).
+
+```yaml
+    environment:
+      VIRTUAL_HOST: example.docker
+      VIRTUAL_PORT: 80
+      # Use the following if you want to handle redirects from http to https yourself.
+      HTTPS_METHOD: noredirect
+
+```
+
+## Using autogenerated certificates
+This require Dory version 1.0.3, use `dory upgrade` to upgrade
+
+If you don't already have a Dory configuration-file, have it generate one by running `dory config` then update the update `ssl_certs_dir` configuration:
+
+```yaml
+  nginx_proxy:
+    enabled: true
+    container_name: dory_dinghy_http_proxy
+    https_enabled: true
+    # Update the follow line to point at the dev_certificates
+    ssl_certs_dir: <your homedir>/.local/share/dev_certificates
+```
+
+Then mount that directory into the apache-fpm container so that its auto-generated certificates will be accessible to Dory.
+
+```yaml
+    volumes:
+      - '${HOME}/.local/share/dev_certificates:/cert:rw'
+```
+
+Then follow the steps in the mkcert sections to specify which certificates to generate and have your OS trust them.
+
+# mkcert
+
+This image has [mkcert](https://github.com/FiloSottile/mkcert)
+builtin.
+
+Install `mkcert` on your host machine and generate and install a root
+certificate by running `mkcert -install` on your host machine.
+
+Then you add the generated CAROOT as a volume (the path on the host
+machine is the output of `mkcert -CAROOT`).
+
+In your `docker-compose.yml` supply one or more host names to be be
+used for HTTPS. Host names will be search for in these location and in
+this order:
+
+1. environment variable `MKCERT_DOMAINS` (several hostnames separated
+   by space is possible, you can even supply a wildcard domain),
+1. the environment variable `VIRTUAL_HOST` (as used by [Dinghy HTTP
+   Proxy](https://github.com/codekitchen/dinghy-http-proxy)), or
+1. the output of `hostname -f` in the container (which can be set with
+   the `hostname` and `domainname` options).
+
+```yaml
+    volumes:
+      - '${HOME}/Library/Application Support/mkcert:/mkcert/mac:ro'
+      - '${HOME}/.local/share/mkcert:/mkcert/linux:ro'
+
+    environment:
+      MKCERT_DOMAINS: "example.docker *.example.docker local.docker"
+
+    hostname: example
+    domainname: docker
+```
+
+# Full example configuration
+
+```yaml
+    volumes:
+      - '${HOME}/Library/Application Support/mkcert:/mkcert/mac:ro'
+      - '${HOME}/.local/share/mkcert:/mkcert/linux:ro'
+      - '${HOME}/.local/share/dev_certificates:/cert:rw'
+
+    environment:
+      MKCERT_DOMAINS: "example.docker *.example.docker local.docker"
+      VIRTUAL_HOST: example.docker
+      VIRTUAL_PORT: 80
+      HTTPS_METHOD: noredirect
