Answer 1

There is a indent issue in first deployment object
change it from
spec:
replicas: 1
selector:
matchLabels:
app.kubernetes.io/name: quality-control-frontend
app.kubernetes.io/instance: RELEASE-NAME
to
spec:
replicas: 1
selector:
matchLabels:
app.kubernetes.io/name: quality-control-frontend
app.kubernetes.io/instance: RELEASE-NAME
Also there is indent problem in service list, need to change it from
- apiVersion: v1
kind: Service
metadata:
name: quality-control-backend
labels:
app.kubernetes.io/name: quality-control-backend
helm.sh/chart: quality-control-0.1.0
app.kubernetes.io/instance: RELEASE-NAME}
app.kubernetes.io/managed-by: Tiller
to
- apiVersion: v1
kind: Service
metadata:
name: quality-control-backend
labels:
app.kubernetes.io/name: quality-control-backend
helm.sh/chart: quality-control-0.1.0
app.kubernetes.io/instance: RELEASE-NAME
app.kubernetes.io/managed-by: Tiller
