Unable to add 1.24.0 Kubernetes cluster #9422

waltforme · 2022-05-16T16:36:55Z

Checklist:

I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
I've included steps to reproduce the bug.
I've pasted the output of argocd version.

Describe the bug

When I tried to add a freshly created v1.24.0 Kubernetes cluster to argocd, I got timeout (see the Logs for details). The cluster can't be added.

Then I created a fresh v1.23.6 cluster, I can add it successfully.

I'm using kubeadm to create my Kubernetes clusters. The only difference between the two creation is one single parameter passed to kubeadm init, which is --kubernetes-version.

This may be related to changes for serviceaccount token in 1.24:

The error is coming from here in code:

argo-cd/util/clusterauth/clusterauth.go

Line 244 in 8cd7d47

return "", fmt.Errorf("Failed to wait for service account secret: %v", err)

So to support 1.24 @danielhelfand : Do you think that argocd to create a secret and then annotate with argocd-manager service account?
like here

I guess not.

waltforme · 2022-05-16T18:03:43Z

@danielhelfand What I tried on my two clusters supports your comment:

On the 1.24.0 cluster:

root@ip-192-168-1-38:~# kc version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.24.0

root@ip-192-168-1-38:~# kc get secret -n kube-system | grep argo
No resources found in kube-system namespace.

On the 1.23.6 cluster:

So to support 1.24 @danielhelfand : Do you think that argocd to create a secret and then annotate with argocd-manager service account? like here

I guess not.

I think the goal should be to support the TokenRequest API, but that will be a bigger change.

The short term solution may be to have the token controller populate a secret created when adding clusters. I haven't weighed the pros/cons of this quite yet.

waltforme · 2022-05-16T21:06:57Z

Just want to share my (hacky) work around on this.

Create a service account token Secret in the kube-system namespace, making sure that the annotation refers to the argocd-manager service account;

apiVersion: v1
kind: Secret
metadata:
  annotations:
    kubernetes.io/service-account.name: argocd-manager
  name: argocd-manager-token
  namespace: kube-system
type: kubernetes.io/service-account-token

Yes, kubernetes 1.24 populates data into the newly created secret;
But the secret is not associated with the sa, the sa still has 0 secrets;

root@ip-192-168-1-38:~# kubectl get sa -n kube-system
NAME                                 SECRETS   AGE
argocd-manager                       0         5d4h

I did kubectl edit sa -n kube-system argocd-manager to manually add the secret to the service account:

secrets:
- name: argocd-manager-token

Now the service account has 1 secret;
And I can add the 1.24.0 cluster now.

root@ip-172-31-55-65:~# argocd cluster add --kubeconfig ./config_kyst_us-west-1 kyst-backend-us-west-1
WARNING: This will create a service account `argocd-manager` on the cluster referenced by context `kyst-backend-us-west-1` with full cluster level admin privileges. Do you want to continue [y/N]? y

Cluster 'https://<hide-my-ip-here>:6443' added

With that, to fix this by the 'short term solution', we may need to not only create a service account token Secret, but also add the secret to the argocd-manager service account.

danielhelfand · 2022-05-19T15:35:59Z

In reviewing this a bit further, I am wondering if the clusterauth package's GetBearerToken function can be altered to always create the secret, bind it to the serviceaccount, and wait for the token controller to appropriately populate the secret. The downside of this is creating an additional token in previous k8s versions.

danielhelfand · 2022-05-24T16:33:23Z

It turns out the TokenRequest API is pretty straight forward to use. Here's a hacky WIP commit to show what it looks like. I have tried both approaches (creating secret and using token request API), and the TokenRequest API seems to resolve the issue. Still need to work through the best approach for maintaining backwards compatibility with the Secret approach for older versions of k8s.

danielhelfand · 2022-05-26T15:47:37Z

Adding in a research doc I have been throwing together.

rishabh625 · 2022-05-31T17:31:55Z

Also i was wondering, that other service account eg: argocd-application-controller will not have secret mounted, so how argocd controller is able to do api call to kube-api server without token and ca.crt

abdennour · 2022-10-05T07:52:07Z

I do confirm . Issue appeared in OCP 4.11 which is based on kubernetes 1.24
I would say this is a bug in kubernetes.
Because I can see this behavior is broken with prometheus in openshift . i.e. oc sa get-token prometheus-k8s -n openshift-monitoring did not work as well.

So this means that parsing the token of an SA has been changed since k8s 1.24

resolution

ns=kube-system
sa_token=$(kubectl -n $ns get secret | grep argocd-manager-token | awk '{print $1}')
kubectl -n $ns patch sa argocd-manager -p '{"secrets": [{"name": "'"${sa_token}"'"}]}'
# then run "argocd cluster add" command again

vedarths · 2022-11-25T11:20:05Z

Hello! Please could someone let me know what version of Argocd we are looking at with the fix for this issue?

I am presuming the only work around for now is to go with what @waltforme has suggested above?

Thanks!

raj13aug · 2022-12-13T11:53:15Z

Currently we are using argocd 2.3.1 and are facing same issue.

Which version of Argocd is suitable to add and register 1.24 Kubernetes cluster?

Thanks

doyelese · 2023-03-08T20:49:06Z

+1 on this, has anyone fixed this?

crenshaw-dev · 2023-03-08T20:52:09Z

The fix was released in 2.3.7 and 2.4.0 onward.

piotrmarczydlo · 2023-03-11T13:00:11Z

can confirm, latest (2.6.4) works also for 1.25

jyothish516 · 2023-05-16T07:24:50Z

@ravindraprasad85 workaround already shared above

Make sure your client is updated also not just your argocd server

Hey @crenshaw-dev we're facing this issue even in v2.7.5+a2430af.dirty.

Is the fix not stable?

josephvano · 2023-10-10T15:28:47Z

I experienced this issue on Argo CD v2.7.2

The workaround was as described above in two separate posts.

For completeness here is my solution.

My context was for local testing multiple clusters

docker desktop k8s with Argo CD installed
kind dev cluster also locally

Steps to solve

Create a kind cluster with an apiServerAddress that is accessible for your Argo CD instance (not localhost). Most likely your IP "192.x.x.x:8443"

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
name: dev-cluster
networking:
  # WARNING: It is _strongly_ recommended that you keep this the default
  # (127.0.0.1) for security reasons. However it is possible to change this.
  apiServerAddress: "<your-local-ip>"
  # By default the API server listens on a random open port.
  # You may choose a specific port but probably don't need to in most cases.
  # Using a random port makes it easier to spin up multiple clusters.
  apiServerPort: 8443

kind docs ref

kind create cluster --config config.yaml

Run the argocd command to add a cluster

argocd cluster add kind-dev-cluster

It will fail with a timeout. That's when have to switch to the kind dev cluster context and create the additional secret for the service account and associate the argocd-manager service account with the new secret.

In your dev-cluster context

kubectl config use-context kind-dev-cluster

Create service account secret

apiVersion: v1
kind: Secret
type: kubernetes.io/service-account-token
metadata:
  annotations:
    kubernetes.io/service-account.name: argocd-manager
  name: argocd-manager-token
  namespace: kube-system

Add secret to service account

apiVersion: v1
kind: ServiceAccount
metadata:
  creationTimestamp: "2023-10-10T15:02:41Z"
  name: argocd-manager
  namespace: kube-system
  resourceVersion: "1526"
  uid: 89721095-63b2-42d0-8dd9-29c2f9fe0379
secrets:
- name: argocd-manager-token
