Azure Pipelines - Error deploying manifest to Kubernetes cluster

I was trying to deploy a manifest through the Kubernetes manifest task  but the task failed with the following error message:

              error: error validating "/home/vsts/work/_temp/Ingress_tags-api-ingress_1622817055216": error validating data: [ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "serviceName" in io.k8s.api.networking.v1.IngressBackend, ValidationError(Ingress.spec.rules[0].http.paths[0].backend): unknown field "servicePort" in io.k8s.api.networking.v1.IngressBackend]; if you choose to ignore these errors, turn validation off with --validate=false

Before I was using the Kubectl task which didn’t complain at all!?

The Kubernetes manifest task validates the manifest before it deploys it (which is in fact a good thing). So let’s have a look what is wrong with the manifest I try to deploy…

Here is the original manifest file:

The problem is that I’m still using the beta syntax for the ingress controller where my apiversion is pointing to v1. In v1 the syntax changed to specify the service Port and Name. Let’s fix this:

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
