Prerequisites

• Helm (package manager for Kubernetes), see also here

Lint charts

In order to lint charts locally, simply run:

helm lint charts/*

or using helm/chart-testing:

docker run -it --network host --workdir=/data --volume ~/.kube/config:/root/.kube/config:ro --volume $(pwd):/data quay.io/helmpack/chart-testing:v3.7.1 ct lint --chart-dirs . --all --validate-maintainers=false

Please note: changes in README.md are ignored.

Hints for developing helm charts

• You can use https://github.com/terrestris/kind-dev-cluster for deploying a local kubernetes cluster on your machine
• If you want to load an image into your kind cluster, use kind load docker-image <image>:<tag> (you maybe need to use docker pull <image>:<tag> before)
• Install a helm chart initially with helm install postgis charts/postgis/ --values charts/postgis/values.yaml
• Upgrade an existing helm chart with helm upgrade postgis charts/postgis --values charts/postgis/values.yaml
• Check kubectl get pods to see status
• Check kubectl describe pod <podname> to see errors in deployment
• Check kubectl logs -f <podname> for container logs
• !Pods do normally not restart if the image has not changed!
  • Use kubectl delete pod <podname> to explicitly restart a container

Setting up shogun cluster with kind-dev-cluster

# first we need to build a container containing the default realm settings
docker build -t keycloak-data:1.0 data/keycloak/
kind load docker-image --name kind-dev-cluster keycloak-data:1.0 docker.terrestris.de/postgis/postgis:15-3.3-alpine docker-public.terrestris.de/terrestris/shogun-admin:11.4.0 docker-public.terrestris.de/shogun/shogun-boot:18.0.0 docker-public.terrestris.de/terrestris/shogun-gis-client:6.9.0
cd charts/shogun
helm dependency build
helm install shogun ./ --values ./values.yaml
