Add Chart Repo to Use these charts

helm repo add homeylab https://homeylab.github.io/helm-charts/
helm repo update homeylab

Search For Apps and Versions

helm search repo homeylab

OCI Support

An OCI supported registry is available for all charts, example using unpoller chart.

Click to Show Example Commands

# pulls chart files locally for you to inspect
helm pull oci://registry-1.docker.io/homeylabcharts/unpoller --version 2.X.X

# outputs all the chart files as stdout
helm show all oci://registry-1.docker.io/homeylabcharts/unpoller --version 2.X.X

# outputs manifests as if an install was being made
# - optionally can use your own values file:  `-f custom-values.yaml`
helm template unpoller oci://registry-1.docker.io/homeylabcharts/unpoller --version 2.X.X

# install chart into your namespace
# - optionally can use your own values file:  `-f custom-values.yaml`
helm install unpoller -n <namespace> oci://registry-1.docker.io/homeylabcharts/unpoller --version 2.X.X

# upgrade existing chart in your namespace
# - optionally can use your own values file:  `-f custom-values.yaml`
helm upgrade unpoller -n <namespace> oci://registry-1.docker.io/homeylabcharts/unpoller --version 3.X.X

Chart Collection

A collection of helm charts that I created for some apps that either do not have an existing chart or the chart has grown stale.

For customizations, it is recommended to use your own values file and specify it when using helm with the -f flag. See Recommendations section below for more details.

Apps available

Application	Description
unpoller	unpoller is a Prometheus exporter that connects to an Unifi Controller(s) and scrapes metrics from your network and devices.
bookstack	bookstack is an app for self and/or collaborated documentation similar to confluence. This chart includes an option to install mariadb alongside it.
nut_exporter	nut_exporter is a Prometheus exporter that connects to a NUT server(s) and scrapes UPS backup metrics.
exportarr	exportarr is a Prometheus exporter that connects to Arr applications and scrapes metrics. This chart has an option to additionally deploy qbittorrent-exporter and tdarr-exporter charts.
qbittorrent-exporter	qbittorrent-exporter is a Prometheus exporter that connects to a qbittorrent instance and scrapes metrics.
tdarr-exporter	tdarr-exporter is a Prometheus exporter that connects to a Tdarr instance and scrapes general statistics for nodes and their running worker processes including transcode and health check jobs.
pihole-exporter	pihole-exporter is a Prometheus exporter that connects to one or more Pi-hole instances and scrapes metrics.

Recommendations

Create A Values File

Use a values file to make changes and save your custom configuration. When using upstream helm charts and specifying your own values file, variables are handled like so:

• First the base default values.yaml in the project/bundle is evaluated and all variables and values loaded.
• When you specify your own file, your configuration is applied on top and overrides (or merges depending on value type) existing configuration loaded from the base values.yaml.

General recommendation is only specify in your own values file what you are customizing or overriding. You may also include variables that are defaulted to a specific value that you need to stay constant, just in case the upstream helm chart changes. This allows you to keep your files minimal and easy to upgrade when values change since your scope is smaller.

Use the -f flag like so, example

helm install -f my-values.yaml unpoller homeylab/unpoller -n unpoller --create-namespace

Use Versioning

Use chart versioning when installing/upgrading charts. This can help prevent unexpected changes/issues from occuring if the upstream chart has been updated in a breaking manner. Example

# Get version to install
helm search repo homeylab/unpoller
NAME             	CHART VERSION	APP VERSION	DESCRIPTION
homeylab/unpoller	1.0.0        	2.8.1      	A Helm chart for Kubernetes

# Install a specific version
helm install -f my-values.yaml unpoller homeylab/unpoller -n unpoller --create-namespace --version 1.0.0

Tested On

All charts are currently tested on:

• k8s v1.29.4+k3s1
• Helm v3.15.1

Chart Testing

WIP Section

To contribute, there are a many ways to do testing and many are valid. I am using Dev Containers extension from VScode to set up a consistent environment across my devices.

To use the same Dev Containers, ensure you have the extension enabled and add a copy of your kubectl config in .devcontainer/. Name it kube_config and it will be ignored by git (in .gitignore) and will be used during Dev Container build.

The provided makefile can then be used for testing via helm and chart-testing.

Example:

# Use `app=` for targeting a chart
# below runs chart-testing for the specified chart/app
make test app=bookstack
