In Chapter 3 of your book on ConfigMap:

kubectl exec -it redis-master-<pod-id> redis-cli
I have below:
$ kubectl exec -it redis-master-78b48bc9df-kn5dd redis-cli
kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.
127.0.0.1:6379>

How can we have the same output as from your book?
Thanks.

While I was running aks code accordingly, I found an error for frontend application " ImagePullBackOff"

error: unable to recognize "certificate-issuer.yaml": no matches for kind "Issuer" in version "cert-manager.io/v1alpha2"

How to solve above error in Chapter 06 p.151?
Thank you!

Hello,

Apparently, HorizontalPodAutoscaler scenario described on page 91 require small change to make it work

--- a/Chapter04/hpa.yaml
+++ b/Chapter04/hpa.yaml
@@ -4,7 +4,7 @@ metadata:
   name: frontend-scaler

Ch 6 pg 149, 150

Followed steps twice from scratch with same result.

kubectl get certificate and kubectl describe certificaterequest

Both return
"No resources found in default namespace."

Thank you

Issue description

If you run following command in the chapter 08
helm repo add svc-cat https://svc-catalog-charts.storage.googleapis.com
you will get like
Error: looks like "https://svc-catalog-charts.storage.googleapis.com" is not a valid chart repository or cannot be reached: failed to fetch https://svc-catalog-charts.storage.googleapis.com/index.yaml : 403 Forbidden

Solution

please refer https://svc-cat.io/docs/install/ this web page to get latest install instruction of service catalog.

In Chapter 3, within the "Installing complex Kubernetes applications using Helm" section (in particular, page 75), you instruct us to run the following 2 commands:

helm repo add stable https://kubernetes-charts.storage.googleapis.com/
helm install handsonakswp stable/wordpress

While the first command completes without issue, the second one returns a warning message as follows:

WARNING: This chart is deprecated
Error: Kubernetes cluster unreachable: Get https://aksworksho-aksworkshop-ee2d54-2227f1c8.hcp.eastus.azmk8s.io:443/version?timeout=32s: dial tcp: lookup aksworksho-aksworkshop-ee2d54-2227f1c8.hcp.eastus.azmk8s.io on 168.63.129.16:53: no such host

Even though I am able to search the repo/hub for alternative Wordpress Helm charts (using helm search repo wordpress) and there are alternatives listed (from the hub specifically), it is not clear how to use one of these as an alternative deployment.
