 # Planned
 
-1.  ~Setup DigitalOcean~
-2.  Add DO infrastructure via ansible
-3.  ~Add traefik for proper proxying~
-4.  Maybe add docker swarm (or k8s?) across both the servers. Might setup the k8s API on the Raspberry Pi.

+## Databases
 
-## Docker Notes
+- [MariaDB](https://store.docker.com/images/mariadb) for a simple database backend
+- [MongoRocks](https://store.docker.com/community/images/jadsonlourenco/mongo-rocks) as a mongoDB server. Uses RocksDB as the backend
 
-- Lots of the above images are from the excellent [LinuxServer.io](https://www.linuxserver.io), and they're doing great work :+1:
-- Most images are running the latest beta (if available) or stable versions.
-- Traefik is running with wildcard certificates.
+## Media
+
+- [Emby](https://store.docker.com/community/images/emby/embyserver) Media Server
+- ~[CouchPotato](https://store.docker.com/community/images/linuxserver/couchpotato), auto-download movies~
+- [Radarr](https://store.docker.com/community/images/linuxserver/radarr), auto-download movies
+- [Sonarr](https://store.docker.com/community/images/linuxserver/sonarr), auto-download TV Shows
+- [Transmission](https://store.docker.com/community/images/linuxserver/transmission), to download torrents
+- [AirSonic](https://store.docker.com/community/images/airsonic/airsonic), for a music server
+- [Ubooquity](https://store.docker.com/community/images/linuxserver/ubooquity), EBooks server with OPDS support
+- [Lychee](https://store.docker.com/community/images/linuxserver/lychee), as a simple image-sharing/hosting service
+
+## Plumbing
+
+- [Traefik](https://store.docker.com/images/traefik) as a reverse-proxy server, and TLS termination
+- [CAdvisor](https://store.docker.com/community/images/google/cadvisor), for basic monitoring
+
+## Misc
+
+- [Wiki.JS](https://store.docker.com/community/images/requarks/wiki) as a simple home-wiki
+- [Radicale](https://store.docker.com/community/images/tomsquest/docker-radicale), for a CalDav/Carddav server
+- [Gitea](https://store.docker.com/community/images/gitea/gitea), git server
+
+Lots of the above images are from the excellent [LinuxServer.io](https://www.linuxserver.io), and they're doing great work :+1:
+
+## Security Headers Note
+
+The following security headers are applied using traefik on all traefik frontend docker backends:
+
+- HSTS
+- Redirect HTTP->HTTPS
+- contentTypeNosniff: true
+- browserXSSFilter: true
+- XFO: Allow-From home.bb8.fun
+- referrerPolicy: no-referrer
+- X-Powered-By: Allomancy
+- X-Server: BlackBox
+- X-Clacks-Overhead "GNU Terry Pratchett" (On some domains)
+
+~~Currently waiting on traefik 1.5.0-rc2 to fix security specific headers issue (marked as TODO above).~~ (Now resolved with new traefik release)
 
 ## Upstream
 
-I've been using this as a contributing opportunity and reporting/fixing issues upstream:
+Issues I've faced/reported as a result of this project:
 
-1.  Airsonic HTTPS proxying is broken. Reported: https://github.com/airsonic/airsonic/issues/641. Turned out to be a known issue: https://github.com/airsonic/airsonic/issues/594. Now fixed.
-2.  Traefik docker backend security headers were broken with dashes. I [reported it here](https://github.com/containous/traefik/issues/2493), and fixed by https://github.com/containous/traefik/pull/2496 :white_check_mark:
-3.  Headphones dies repeatedly with no error logs. Yet-to-report. (Already reported, fails due to classical artists)
-4.  Terraform doesn't parse mariadb version numbers. Report: https://github.com/terraform-providers/terraform-provider-mysql/issues/6. Filed a [PR to fix](https://github.com/hashicorp/go-version/pull/34) and [to bump the go-version dependency](https://github.com/terraform-providers/terraform-provider-mysql/pull/27) :white_check_mark:
-5.  `elibsrv` didn't support ebook-convert, only mobigen. PR is at https://github.com/captn3m0/elibsrv/pull/1. Merged to `elibsrv` trunk, will be part of next release.
-6.  `ubooquity` docker container doesn't let you set admin password: https://github.com/linuxserver/docker-ubooquity/issues/17. (Couldn't reproduce, closed) :white_check_mark:
-7.  Traefik customresponseheaders can't contain colons on the docker backend: https://github.com/containous/traefik/issues/2517. Fixed with https://github.com/containous/traefik/pull/2509 :white_check_mark:
-8.  Traefik Security headers don't overwrite upstream headers: https://github.com/containous/traefik/issues/2618 :white_check_mark:
-9.  Transmission exporter broke with different data types while unmarshalling JSON in go. I filed a PR https://github.com/metalmatze/transmission-exporter/pull/2 :white_check_mark:
-10. Radarr official docker container was [running a very old `mediainfo`](https://github.com/Radarr/Radarr/issues/2668#issuecomment-376310514). [Filed a fix to upgrade `mediainfo` on the official radarr image](https://github.com/linuxserver/docker-baseimage-mono/pull/3) :white_check_mark:
-11. Patched the [speedtest-exporter](https://github.com/stefanwalther/speedtest-exporter/pull/7) to use Alpine and upgraded Node.JS for a smaller updated build.
-12. Faced (4) above again because mariadb decided to add `:` in the version response. [Workaround was to force set `--version=10.3-mariadb`](https://git.captnemo.in/nemo/nebula/commit/5f47a08bb55eea2c708c41668657ac1efa84c72a)
-13. Reported [2 critical security issues in Abstruse CI](https://github.com/bleenco/abstruse/issues/363). :white_check_mark:
-14. Faced (13) above again with postgres, thankfully [someone already fixed version parsing](https://github.com/terraform-providers/terraform-provider-postgresql/pull/31) :white_check_mark:
-15. RSS Bridge was missing an official Docker Image. [I Filed a PR](https://github.com/RSS-Bridge/rss-bridge/pull/720) :white_check_mark:
+1. Airsonic HTTPS proxying is broken. Reported: https://github.com/airsonic/airsonic/issues/641. Turned out to be a known issue: https://github.com/airsonic/airsonic/issues/594.
+2. Traefik docker backend security headers were broken with dashes. Reported at https://github.com/containous/traefik/issues/2493, and fixed by https://github.com/containous/traefik/pull/2496 :white_check_mark:

+4. Terraform doesn't parse mariadb version numbers. Report: https://github.com/terraform-providers/terraform-provider-mysql/issues/6. Got this fixed myself by filing a PR: https://github.com/hashicorp/go-version/pull/34. Another PR pending in the [provider](https://github.com/terraform-providers/terraform-provider-mysql/pull/27) to bump the go-version dependency. :white_check_mark:
+5. `elibsrv` didn't support ebook-convert, only mobigen. PR is at https://github.com/captn3m0/elibsrv/pull/1. I've to get this merged upstream for the next release.
+6. `ubooquity` docker container doesn't let you set admin password: https://github.com/linuxserver/docker-ubooquity/issues/17. (Couldn't reproduce, closed) :white_check_mark:

 # Plumbing
 
 Their is a lot of additional infrastructure that is _not-yet_ part of this repo. This includes:
 
-1.  The Digital Ocean droplet running DNSCrypt and simpleproxy to proxy over a openvpn connection to this box.
-2.  openbox, kodi configuration to run on boot along with the Steam Controller for the HTPC setup
-3.  Docker main configuration with half-baked CA setup
-4.  btrfs-backed subvolumes and snapshotting for most things in /mnt/xwing/ (in-progress)
-5.  User-creation on the main server. (I'm using a common user for media applications and specific users for other applications)
