Table of Contents
Project Lifecycle
Projects will fall into one of the three following categories:
- Incubating
- Graduated
- Retired
Incubating projects are experimental or prototypal. They're being actively developed and aren't ready for production deployment. These projects may appear and disappear without warning and are not stable. There is no minimum requirement for a project to be in incubation.
Graduated projects are in-use, stable, and production ready. They met the graduation requirements and are actively maintained.
Retired projects are no longer in use or recommended. They are kept for reference. Retired projects must meet the retirement requirements
Supported Projects
All projects will fall into one of the following categories:
- hardware
- infrastructure
- cloud
- systemd
- podman
- docker
- kubernetes
Hardware will contain projects that relate to specific machines or equipment. 3D printers, Raspberry Pis, and other IOT devices qualify as specialized hardware that needs documentation and configuration.
Infrastructure will contain projects that set up the environments for the remaining listed project types. For example, infrastructure will contain "how to set up a linux box with docker" or "how to set up a k3s cluster for kubernetes".
Cloud projects are for specific cloud providers.
Systemd projects are designed to be installed with ansible and run via systemd on a linux VM or other linux hardware.
Podman projects are either designed to be run as quadlets or as podman containers outright.
Docker projects are either docker-compose or some form of docker run command.
Kubernetes projects are helm, kustomize, kubectl, or some other kubernetes compliant deployment.

Apps (TODO: Move these into their respective folders)
Gitea
Gitea provides a helm chart here. We're not going to modify much, but we are going to solidify some of the default values in case they decide to change things. This is the first chart (besides ingress-nginx) where we need to pay attention to the MetalLB annotation. This has been set in the values.yaml file.
Staging
There is a gitea-staging.yaml file with staging values. This should be installed in
the gitea-staging namespace. Follow the instructions below, but replace the gitea
namespace with gitea-staging. Staging is useful for testing major release upgrades,
especially since Gitea tends to change how values.yaml is structured.
Install
First we need to create the gitea admin secret
kubectl create namespace gitea
kubectl create secret generic gitea-admin-secret \
-n gitea \
--from-literal=username='gitea-admin' \
--from-literal=password="$(pwgen -c -s 64 | head -n 1)" \
--from-literal=email=''
helm repo add gitea-charts https://dl.gitea.io/charts/
helm repo update
helm upgrade --install \
gitea \
gitea-charts/gitea \
--values gitea/gitea-values.yaml \
--namespace gitea \
--create-namespace
If you need to backup your database you can run:
# Backup
kubectl exec -it -n gitea gitea-postgresql-0 -- \
pg_dump \
--no-owner \
--dbname=postgresql://gitea:gitea@localhost:5432 > gitea_backup.db
# Take gitea down to zero pods
kubectl scale statefulset gitea --replicas 0
# Drop the existing database
kubectl exec -it -n gitea gitea-postgresql-0 -- psql -U gitea
\c postgres;
drop database gitea;
CREATE DATABASE gitea WITH OWNER gitea TEMPLATE template0 ENCODING UTF8 LC_COLLATE 'en_US.UTF-8' LC_CTYPE 'en_US.UTF-8';
exit
# restore from backup
kubectl exec -it -n gitea gitea-postgresql-0 -- \
psql \
postgresql://gitea:gitea@localhost:5432 gitea < gitea_backup.db
# Restore gitea to 1 pod
kubectl scale statefulset gitea --replicas 1
Minecraft
Minecraft is available through the custom helm chart (including a server downloader). The example below installs nimcraft. For each installation you'll want to create your own values.yaml with a new port. The server-downloader is called "minecraft_get_server" and is available on Github.
Testing
helm upgrade --install \
testcraft \
./minecraft \
--namespace minecraft \
--create-namespace
Nimcraft
helm upgrade --install \
nimcraft \
./minecraft \
--namespace minecraft \
--create-namespace
Courtnie
helm upgrade --install \
courtniecraft \
./minecraft \
--namespace minecraft \
--create-namespace
Snapdrop
Snapdrop is a file sharing app that allows airdrop-like functionality over the web
helm upgrade --install \
snapdrop \
./snapdrop \
--namespace snapdrop \
--create-namespace
Jellyfin
This assumes you have a media NFS share.
helm upgrade --install \
jellyfin \
./jellyfin \
--namespace jellyfin \
--create-namespace
Iperf3
This creates a basic iperf3 server.
helm upgrade --install \
iperf3 \
./iperf3 \
--namespace iperf3 \
--create-namespace
Wordpress
The bitnami wordpress chart allows enough customization to
work on a custom K3S server. With some tweaks it's quite
good. Use the values in bitnami/wordpress.yaml as a starting
point.
helm upgrade --install \
wordpress \
-f bitnami/wordpress.yaml \
--set wordpressUsername=admin \
--set wordpressPassword=password \
--set mariadb.auth.rootPassword=secretpassword \
oci://registry-1.docker.io/bitnamicharts/wordpress
Grafana
https://grafana.com/docs/grafana/latest/setup-grafana/installation/kubernetes/
Grafana has a kubernetes yaml they prefer you use. See kubectl/grafana.yaml.
kubectl apply -f kubectl/grafana.yaml
