helm not creating the resources

Question

I have tried to run Helm for the first time. I am having deployment.yaml, service.yaml and ingress.yaml files alongwith values.yaml and chart.yaml.

deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: abc
  namespace: xyz
  labels:
    app: abc
    app.kubernetes.io/managed-by: {{ .Release.Service }}
spec:
  replicas: 3
  template:
    spec:
      containers:
        - name: abc
          image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
          ports:
            -
              containerPort: 8080

service.yaml

apiVersion: v1
kind: Service
metadata:
  name: abc
  labels:
    app.kubernetes.io/managed-by: {{ .Release.Service }}
  namespace: xyz
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-ssl-cert: {{ .Values.service.sslCert }}
spec:
  ports:
    - name: https
      protocol: TCP
      port: 443
      targetPort: 8080
    - name: http
      protocol: TCP
      port: 80
      targetPort: 8080
  type: ClusterIP
  selector:
    app: abc

ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: "haproxy-ingress"
  namespace: xyz
  labels:
    app.kubernetes.io/managed-by: {{ .Release.Service }}
  annotations:
    kubernetes.io/ingress.class: alb

From what I can see I do not think I have missed putting app.kubernetes.io/managed-by but still, I keep getting an error:

rendered manifests contain a resource that already exists. Unable to
continue with install: Service "abc" in namespace "xyz" exists and
cannot be imported into the current release: invalid ownership
metadata; label validation error: missing key
"app.kubernetes.io/managed-by": must be set to "Helm"; annotation
validation error: missing key "meta.helm.sh/release-name": must be set
to "abc"; annotation validation error: missing key
"meta.helm.sh/release-namespace": must be set to "default"

It renders the file locally correctly.

helm list --all --all-namespaces returns nothing. Please help.

You already have some resources, e.g. service abc in the given namespace, xyz that you're trying to install via a Helm chart.

Delete those and install them via helm install.

$ kubectl delete service -n <namespace> <service-name>
$ kubectl delete deployment -n <namespace> <deployment-name>
$ kubectl delete ingress -n <namespace> <ingress-name>

Once you have these resources deployed via Helm, you will be able to perform helm update to change properties.

Remove the "app.kubernetes.io/managed-by" label from your yaml's, this will be added by Helm.
