Example service

https://github.com/rumyantseva/go-sofia

Check your Kubernetes-readines

Follow the instruction: https://ui.k8s.community Kubernetes dashboard: https://dash.k8s.community

USER=your_github_user
kubectl run hello-app --image=gcr.io/google-samples/hello-app:1.0 --port=8080 -n ${USER}
kubectl expose deployment hello-app -n ${USER}

Ingress configuration (example):

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: hello-app-ingress
  namespace: rumyantseva
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: "/"
spec:
  rules:
  - host: services.k8s.community
    http:
      paths:
      - path: /rumyantseva/hello
        backend:
          serviceName: hello-app
          servicePort: 8080
  tls:
  - hosts:
    - services.k8s.community
    secretName: tls-secret

kubectl apply -f ingress.yaml

Build a Docker image and run container

docker build -t go-sofia .
docker run -p 8080:8080 -p 8585:8585 -t go-sofia

MVP to complete the workshop

• Set up https://github.com/apps/k8s for your service
• Provide helm configuration and Makefile (you can use https://github.com/rumyantseva/go-sofia as an example)
• Prepare a new "release" branch (e.g. release/0.0.1, release/0.0.2 etc)
• Push changes to the release branch
• You changes should be triggered by the CI and you will see the message next to the commit as soon as the CI process completed
