manifests/0prometheus-operator-0alertmanagerCustomResourceDefinition.yaml cannot be validated

[ghost]

What did you do?
I got the project via "go get" and also via "git clone".
Executing kubectl create -f bundle.yaml and then kubectl create -f contrib/kubernetes-prometheus/manifests
What did you expect to see?
A flawless deploy.
What did you see instead? Under which circumstances?
In both cases I saw errors being raised.
The yml-files appear to be recreating state already present elsewhere and not all of them can be validated.

[metalmatze]

Can you please elaborate on this?

The yml-files appear to be recreating state already present elsewhere and not all of them can be validated.

Thanks.

[ghost]

Running kubectl create -f bundle.yaml will create e.g. a clusterrole.
Running kubectl create -f contrib/kubernetes-prometheus/manifests will try to create a clusterrole with the same name.
That's where the 2 Error from server (AlreadyExists): are coming from in my last post.

The validation-thing is the one most concerning for me though.

[brancz]

Sorry for taking so long, but I realized you apply the bundle and then the entire stack again. The bundle is just for a quickstart. The kube-prometheus stack is the entire stack, the bundle is a subset of kube-prometheus, as you seem to want the whole stack, just apply the latter 🙂 .

(fwiw I just tried and successfully deployed the whole stack on a new cluster without any issues)

[alok87]

[brancz]

I am unable to reproduce this with a minikube cluster. Do you have any steps for reproducing your cluster that yields this?

[ghost]

brancz,

Now it is me who has to apologize for being late. -.-
I did as you suggested above but just one of the commands to create the cluster is not working either.
Here is a minimal configuration that allows you to get a cluster-configuration that might be able to reproduce the error.
(Was done with K8s 1.11, upgraded to 1.13 since then but issue still persists).
The OS is Ubuntu Xenial .

echo 1 > /proc/sys/net/ipv4/ip_forward
&& swapoff -a
&& apt-get update && apt-get install -y apt-transport-https
&& curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
&& echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" > /etc/apt/sources.list.d/kubernetes.list
&& apt-get update
&& apt-get install -y kubelet kubeadm kubernetes-cni
&& apt-get install -y docker.io
&& systemctl enable docker && systemctl start docker
&& kubeadm init --pod-network-cidr=10.244.0.0/16
&& mkdir $HOME/.kube
&& cat /etc/kubernetes/admin.conf > $HOME/.kube/config
&& kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/v0.10.0/Documentation/kube-flannel.yml
&& kubectl taint node onlyNodeInCluster node-role.kubernetes.io/master:NoSchedule-

It is for a single node "cluster" but since the configuration-file is not understood by Kubernetes I think the fact that there are no minions does not matter.

[s-urbaniak]

@asodastreamer I was able to reproduce this on minikube when I explicitely install kubectl in v1.9.3. I believe kubernetes only guarantees one minor version compatibility difference, i.e. 1.9 and 1.10, but in your case you have a hop of 4 minor versions to 1.13 and 2 minor version hops between 1.9 and 1.11.

Please install the same version of kubectl as your server has to have the strongest conversion guarantee.

[s-urbaniak]

@alok87 do you mind to also verify if bumping your kubectl client resolves the issue?

[wtan825]

I got the same issue with Client Version 1.9.3 and Server Version 1.11.5. As @s-urbaniak suggested, it is solved by installing the same version of kubectl as my server.

[brancz]

I'm closing this as we have multiple reports of @s-urbaniak's answer being correct. Should this not be the case for you and the problem continues to exist, please comment here or open a new issue. Thanks!
