+# API Only: Docker
+
+## Only installs the API (webserver) and not the Pritunl VPN itself.
+This approach runs this API, either on port 80 or behind Traefik, either on docker swarm or single daemon.
+
+You need to have docker up and running on your server.
+
+- In your server, clone this repo, then `cd` to the cloned folder.
+- Copy the docker-compose file provided in `<repo_root>/docker/api-only/docker-compose.yml` to
+  the root of the cloned folder. 
+  
+  You shall now have: `<repo_root>/docker-compose.yml`
+- Modify the `<repo_root>/docker-compose.yml` to fit your needs and config
+
+  _Watch for volumes, docker swarm or single daemon, behind Traefik or not and the HOST value if behind traefik:_
+
+   In case you run behind Traefik, you need to setup the traefik router HOST
+
+   You need correctly setup traefik and docker network (here called proxy_external)
+
+   **(!) Make sure the mount volumes match correctly.**
+
+   * The first volume is the path to the www folder from the root of this repo.
+
+   The path shall be a full path, or be next to this docker-compose.yml file. 
+
+   No parent folder navigation like `../../../` is allowed by docker.
+
+   * The second volume is the path to the nginx server config file.
+   
+   This needs the commited nginx server config (or your own adapted version) to work properly.
+   
+   See the file `<repo_root>/docker/api-only/conf.d/pritunl-fake-api.conf` for more details.
+- Run the updated `docker-compose.yml` file in daemon mode with:
+
+  `docker-compose up -d`
