README.md

nebula

Nebula header image

Where stars are born.

Manages the local infrastructure of my home server. I'm also doing blog posts around the same:

  1. Part 1, Hardware
  2. Part 2, Terraform/Docker
  3. Part 3, Learnings
  4. Part 4, Migrating from Google (and more)
  5. Part 5, Networking

The canonical URL for this repo is https://git.captnemo.in/nemo/nebula/. A mirror is maintained on GitHub at https://github.com/captn3m0/nebula

modules

  1. docker: to actually run the services. Catch-all for miscellaneous containers
  2. cloudflare: to manage the DNS.
  3. mysql: to create mysql users and databases.
  4. media: Media related containers (Jackett, Lidarr, Radarr, Sonarr)
  5. Monitoring: Monitoring related resources (Cadvisor, Grafana, NodeExporter, Prometheus, Transmission-Exporter)
  6. Gitea: Just git.captnemo.in
  7. tt-rss: Tiny-Tiny RSS Web reader
  8. Radicale: CardDav/CalDav webserver

Self-learning project for terraform/docker.

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, 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:

  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, 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 and 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. 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. Filed a fix to upgrade mediainfo on the official radarr image :white_check_mark:
  11. Patched the speedtest-exporter 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
  13. Reported 2 critical security issues in Abstruse CI. :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)
