Getting started

See Helm’s documentation to get started with Helm.

See the GOV.UK Kubernetes Cluster User Docs for an introduction to the cluster or ask #govuk-platform-engineering in Slack.

Local development

Most of the charts in this repository are designed to be installed via Argo CD rather than by helm. We hope to improve portability over time.

Prerequisites

Install Helm and yq
```
brew install helm yq
```

Clone the repository

git clone git@github.com:alphagov/govuk-helm-charts.git

Configure git hooks

cd govuk-helm-charts &&
git config core.hooksPath git-hooks

Installing an application chart without Argo CD

cd charts/app-config

ENVIRONMENT=integration
APP=content-publisher
helm install $USER-${APP?} ../generic-govuk-app --values <(
  helm template . --values values-${ENVIRONMENT}.yaml |
  yq e '.|select(.metadata.name=="'$APP'").spec.source.helm.values'
) --set sentry.enabled=false --set rails.createKeyBaseSecret=false

You can inspect the final template output by running helm template instead of helm install.

Chart repository

Some of the charts in this git repository are published via GitHub Actions to a chart repository hosted on GitHub Pages.

To add the chart repo to Helm:

helm repo add govuk-helm-charts https://alphagov.github.io/govuk-helm-charts/

You can then run helm search repo <alias> to see the charts. helm repo update retrieves the latest versions of the packages.

Schemas

kubeconform runs as a pre-merge check. The JSON schemas that it validates against are in the schemas/ directory.
