Changing secrets of kiali in istio is not working

问题

I have deployed istio in my eks cluster with demo profile. demo has kiali deployment with it. The access secret for kiali dashboard is ( username:admin,password:admin ).I was able to access my dashboard with this credentials. Then I created my own secrets.

$ echo shajaltest | base64
$ c2hhamFsdGVzdAo=

Deleted the secrets for kiali.

$ kubectl delete secrets kiali -n istio-system

Deployed the secrets again with this yaml

apiVersion: v1
kind: Secret
metadata:
  name: kiali
  namespace: istio-system
  labels:
    app: kiali
type: Opaque
data:
  username: c2hhamFsdGVzdAo=
  passphrase: c2hhamFsdGVzdAo=

After all of that I deleted the pod of kiali. After that I can not access my dashboard with this username and password. What should I do ?

I also checked the secrets of kiali. It has updated with recent secret value.

Here is the log of kiali pod.

Have you tried to follow the istio documentation about changing the credentials in kiali?

I made a reproduction of your issue with below steps and everything worked just fine.

Enter a Kiali username when prompted:

KIALI_USERNAME=$(read -p 'Kiali Username: ' uval && echo -n $uval | base64)

Enter a Kiali passphrase when prompted:

KIALI_PASSPHRASE=$(read -sp 'Kiali Passphrase: ' pval && echo -n $pval | base64)

To create a secret, run the following commands:

NAMESPACE=istio-system

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
  name: kiali
  namespace: $NAMESPACE
  labels:
    app: kiali
type: Opaque
data:
  username: $KIALI_USERNAME
  passphrase: $KIALI_PASSPHRASE
EOF

And simply recreate the kiali pod with

kubectl delete pod <name_of_the_kiali_pod> -n istio-system

EDIT

As @Shajal Ahamed mentioned in comments the problem was absence of -n, if you want to use just echo, then use.

echo -n username | base64
echo -n passphrase | base64
