    • Let’s add the Kubernetes Services to connect the Ingress we just created and the Deployments we will create, as we did in previous chapters.

    Create two files named helm/buttons/templates/nginx-service.yaml and helm/buttons/templates/python-service.yaml.

    On the first one, add the following content:

    apiVersion: v1
kind: Service
metadata:
  name: {{ .Values.nginx.name }}
  labels:
    {{- include "button.labels" . | nindent 4 }}
spec:
  type: {{ .Values.nginx.service.type }}
  ports:
    - port: {{ .Values.nginx.service.port }}
      targetPort: http
      protocol: TCP
      name: http
  selector:
    app: {{ .Values.nginx.name }}

    As you can see, the content from this file is coming from .Values.nginx. So let’s update our helm/buttons/values.yaml with the newly required parameters:

    nginx:
  name: nginx
  service:
    type: ClusterIP
    port: 80

    Now a challenge!

    Create yourself the python-service.yaml template and change the values.yaml file accordingly.

    Commit your changes, go to your EC2 instance and upgrade the Helm installation with the new Services. If you don’t remember the commands, check the PROJECT: Creating the Ingress for tips!
