+# Gogs via Docker
+
+## Concept
+
+* nginx reverse proxy (in docker container), automatically configured (except for the ssl certificates)
+* backend gogs instance (in docker container)
+
+## Getting the images
+
+Just pull them:
+```sh
+docker pull hasufell/alpine-gogs
+docker pull hasufell/alpine-nginx-proxy
+```
+
+## Configuration
+
+Gogs is configured via the web interface once the instance has started.
+
+In addition, the following environment variables can be passed via `-e` to
+`docker run`:
+* `VIRTUAL_HOST`: sets the hostname for connecting to the gogs backend server
+* `VIRTUAL_PORT`: tells the front proxy on which port to contact the backend server
+* `GOGS_SSH_PORT`: this only changes the port of the sshd service, you will still have to adjust it in the web configuration interface (optional, default 22)
+
+### Certificates
+
+We need certificates which are named according to the hostname
+of the gogs instance (e.g. if you will access gogs via
+`https://gogs.foo.com`, then you name your certificates files
+`gogs.foo.crt` and `gogs.foo.key`).
+
+Just drop these in a directory. We will mount this directory into the
+container later.
+
+## Running for the first time
+
+Create the volumes. This will create a persistent data volume container.
+You should not remove it (keep in mind that this container is not running).
+```sh
+docker run \
+	--name=gogs-volumes \
+	-v /data \
+	hasufell/alpine-gogs \
+	echo gogs-volumes
+```
+
+Now we start the front proxy.
+```sh
+docker run -ti -d \
+	-v /var/run/docker.sock:/tmp/docker.sock:ro \
+	-v <full-path-to-nginx-certs>:/etc/nginx/certs \
+	-p 80:80 \
+	-p 443:443 \
+	hasufell/alpine-nginx-proxy
+```
+
+Now we can start the gogs instance.
+
+```sh
+docker run -ti -d \
+	--volumes-from gogs-volumes \
+	--name=gogs \
+	-e VIRTUAL_HOST=<hostname> \
+	-e VIRTUAL_PORT=3000 \
+	-e GOGS_SSH_PORT=<ssh-port> \
+	-p <sshport>:<sshport> \
+	hasufell/alpine-gogs
+```
+
+Note that `VIRTUAL_HOST` and `VIRTUAL_PORT` are __strictly__ necessary,
+because they are used by the front proxy to update its configuration
+automatically.
+
+## Initial web configuration
+
+Make sure:
+* `Database Type` is SQLite3
+* `Domain` is set to your domain
+* `SSH Port` is set to what you specified in `GOGS_SSH_PORT` (or 22 for default)
+* `Application URL` is `https://<domain>/` (not `http`) _without_ the Port 3000
+
+## Update procedure
+```sh
+docker stop gogs
+docker rm gogs
+docker pull hasufell/alpine-gogs
+docker run -ti -d \
+	--volumes-from gogs-volumes \
+	--name=gogs \
+	-e VIRTUAL_HOST=<hostname> \
+	-e VIRTUAL_PORT=3000 \
+	-e GOGS_SSH_PORT=<ssh-port> \
+	-p <sshport>:<sshport> \
+	hasufell/alpine-gogs
+```
