Installing charts from Flant's ChartMuseum

Our main directory for public charts is https://charts.flant.com/common/github. To use it, you need to add this repository to your Helm (e.g. it will be called flant_common_github):

helm repo add flant_common_github https://charts.flant.com/common/github
helm repo update

Now you can helm install the charts you need. Currently, we have the following charts (generated automatically via GitHub Actions):

• k8s-image-availability-exporter — k8s-iae is a Prometheus exporter that warns you proactively about images that are defined in Kubernetes objects but are not available in the container registry;
• loghouse — loghouse is a log management solution for Kubernetes based on ClickHouse and Fluentd;
• flant-lib — Flant's Helm library with useful helpers/functions.

Using ChartMuseum in your apps

To use these charts in your apps, you need to add the corresponding .helm/requirements.yaml file.

For example, to use a chart for the Loghouse, you'll need to put the following in its requirements.yaml:

dependencies:
- name: loghouse
  version: ~0.3
  repository: https://charts.flant.com/common/github
  condition: loghouse.enabled

Adding a new chart

1. Place a chart in .helm/charts/<new chart name>
2. Add a dependency for it:

   .helm/requirements.yaml:
   ===============================
   - name: <new chart name>
     condition: <new chart name>.enabled
     version: ~<major version only, minor/patch not required>
   

3. Chart should be disabled by default:

   .helm/charts/<new chart name>/values.yaml:
   =================================================
   enabled: false
