+# Halcyon Docker
+
+This Docker setup for Halcyon includes just Halcyon, php-fpm and the necessary locales for internationalization support in Halcyon.
+
+You'll need to use the main repo's nginx/apache/caddy configs for reverse proxy to the container. traefik will likely work but is untested.
+
+# Build Halcyon Container
+
+``` sh
+
+cd /opt/halcyon/docker
+docker build -t halcyon/halcyon:latest .
+
+```
+
+# Configuration
+
+The container has the official example configs stored at ```/var/www/html/config``` inside the image. You can copy the examples from the container to the server via a temporary container and volume.
+
+The configs must be adjusted ahead of running the container for production use.
+
+Please note: The container build will checkout the latest release of Halcyon which may *not* match the current master brach HEAD. It's advisable to use the below to copy the configs so you're using the same config examples as the version deployed in the container.
+
+Example:
+
+``` sh
+
+cd /opt/halcyon
+mkdir config
+docker run --rm -it \
+    --entrypoint /bin/sh \
+    -v /opt/halcyon/config:/var/www/html/config \
+    halcyon/halcyon:latest
+cp /var/www/html/config.example/* /var/www/html/config/
+exit
+
+```
+
+# Running
+
+An example for running the container is below.
+
+``` sh
+
+docker run \
+    --name halcyon \
+    --restart unless-stopped \
+    --net docker-private \
+    --ip 172.30.12.13 \
+    -e TZ=UTC \
+    -e DEBUG=1 \
+    -v /opt/halcyon/config:/var/www/html/config \
+    halcyon/halcyon:latest
+
+```
