# 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.

## Docker Notes
- 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.
## Upstream
Issues I've faced/reported as a result of this project:
I've been using this as a contributing opportunity and reporting/fixing issues upstream:
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:

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:
# 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)
