# nebula ![Nebula header image](https://cdn.spacetelescope.org/archives/images/thumb700x/heic0707a.jpg) >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](https://captnemo.in/blog/2017/09/17/home-server-build/) 2. [Part 2, Terraform/Docker](https://captnemo.in/blog/2017/11/09/home-server-update/) 3. [Part 3, Learnings](https://captnemo.in/blog/2017/12/18/home-server-learnings/) 4. [Part 4, Migrating from Google (and more)](https://captnemo.in/blog/2017/12/31/migrating-from-google/) The canonical URL for this repo is https://git.captnemo.in/nemo/nebula/. A mirror is maintained on GitHub. # 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. # Service List Currently running the following (all links are to the `store.docker.com` links for the docker images that I'm using: | image | tag | size | category/module | |--------------------------------|---------|------|-----------------| | prom/node-exporter | v0.15.2 | 22.8 | monitoring | | redis | alpine | 27.8 | gitea | | linuxserver/transmission | latest | 43.9 | media | | traefik | 1.6 | 51.8 | docker | | google/cadvisor | latest | 62.2 | monitoring | | odarriba/timemachine | latest | 77.2 | backup | | gitea/gitea | 1.4 | 77.4 | gitea | | linuxserver/heimdall | latest | 101 | general | | linuxserver/tt-rss | latest | 108 | tt-rss | | prom/prometheus | latest | 113 | monitoring | | linuxserver/ubooquity | latest | 114 | docker | | captn3m0/speedtest-exporter | alpine | 115 | monitoring | | tomsquest/docker-radicale | latest | 130 | radicale | | linuxserver/lychee | latest | 154 | lychee | | linuxserver/resilio-sync | latest | 167 | resilio | | emby/embyserver | latest | 202 | media | | linuxserver/airsonic | latest | 239 | media | | grafana/grafana | latest | 301 | monitoring | | requarks/wiki | latest | 317 | wiki | | percona/percona-server-mongodb | latest | 321 | wiki | | mariadb | 10.3 | 402 | db | | linuxserver/jackett | latest | 556 | media | | linuxserver/sonarr | latest | 562 | media | | linuxserver/radarr | latest | 566 | media | | linuxserver/lidarr | latest | 574 | media | ## 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: 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 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. 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) 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. # 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) # License All code in this repository is shared under the [MIT License](https://nemo.mit-license.org/).
