Sample-helm

Sample helm based web application using an init container

Needs: minikube and helm

1. Build images

To build the images inside minikube use:

./images/dump-envs/build.sh
./images/env-web-server/build.sh

2. Install chart

To install the chart:

helm install test-env-web charts/env-web-server

3. Debug

To access the actual applications from your machine:

minikube service test-env-web

To visualize the state of the system:

kubectl get all

or, if you prefer a visual dashboard:

minikube dashboard

To visualize the logs:

# show pods
kubectl get pods
kubectl logs <pod-id>

To visualize the logs for an init container

kubectl logs <pod-id> -c <init-container-name> # (in our case "test-env-web-init")

Deploy with argo-cd

Needs: argo-cd and an authenticated argo cli

To create as argocd app

argocd app create test-env-web \
  --repo https://github.com/lmammino/minikube-helm-init-container \
  --path argocd \
  --dest-namespace default \
  --dest-server https://kubernetes.default.svc \
  --directory-recurse

Keep in mind that the images in this project are NOT published anywhere, so you need to build them locally before you can deploy the app.

This particular setup requires manual synchronisation of deployments (it will not check git)
