+# Miniflux
+
+Miniflux is a lightweight RSS reader, developed by [Frédéric Guillot](https://github.com/fguillot). (Who also happens to be the developer of the favorite Open Source Kanban app, [Kanboard](https://kanboard.net/))
+
+Features (among many) that I appreciate:
+
+* Compatible with the Fever API, read your feeds through existing mobile and desktop clients (_This is the killer feature for me. I hardly ever read RSS on my desktop, I typically read on my iPhone or iPad, using [Fiery Feeds](http://cocoacake.net/apps/fiery/) or my new squeeze, [Unread](https://www.goldenhillsoftware.com/unread/)_)
+* Send your bookmarks to Pinboard, Wallabag, Shaarli or Instapaper (_I use this to automatically pin my bookmarks for collection on my [blog](https://www.funkypenguin.co.nz/blog/)_)
+* Feeds can be configured to download a "full" version of the content (_rather than an excerpt_)
+* Use the Bookmarklet to subscribe to a website directly from any browsers
+
+
+## Ingredients
+
+1. [Docker swarm cluster](/ha-docker-swarm/) with [persistent shared storage](/ha-docker-swarm/shared-storage-ceph.md)
+2. [Traefik](/ha-docker-swarm/traefik) configured per design
+
+## Preparation
+
+### Setup data locations
+
+Create the location for the bind-mount of the application data, so that it's persistent:
+
+```
+mkdir -p /var/data/miniflux
+```
+
+
+### Setup Docker Swarm
+
+Create a docker swarm config file in docker-compose syntax (v3), something like this:
+
+```
+version: '3'
+
+services:
+  miniflux:
+    image: saghul/miniflux
+    volumes:
+     - /etc/localtime:/etc/localtime:ro
+     - /var/data/miniflux/:/config/
+    networks:
+    - traefik
+    deploy:
+      labels:
+        - traefik.frontend.rule=Host:miniflux.example.com
+        - traefik.docker.network=traefik
+        - traefik.port=80
+
+networks:
+  traefik:
+    external: true
+```
+
+
+## Serving
+
+### Launch Miniflux stack
+
+Launch the Huginn stack by running ```docker stack deploy miniflux -c <path -to-docker-compose.yml>```
+
+Log into your new instance at https://**YOUR-FQDN**. Default credentials are admin/admin, after which you can change (under 'profile') and add more users.
+
+## Chef's Notes
+
+1. I chose [saghul/miniflux](https://hub.docker.com/r/saghul/miniflux/)'s over the "official" [miniflux/miniflux](https://hub.docker.com/r/miniflux/miniflux/) image, because currently the official image doesn't log to stdout (which you want, for docker logging commands), and because I have an expectation that nginx is more lightweight (faster) than apache.
+2. Find the bookmarklet under the "about" page. I know, it took me ages too.
