Problem installing on GKE

[MrPallaBall]

Hi,
I have several problems installing strimzi-kafka-operator on GKE using the official Quickstart https://strimzi.io/docs/operators/latest/quickstart.html#proc-install-product-str

I edit the install/cluster-operator/060-Deployment-strimzi-cluster-operator.yaml file and set the STRIMZI_NAMESPACE environment variable as is:

env:
- name: STRIMZI_NAMESPACE
  value: my-kafka-project

When I execute the command on the official guide I have this stack trace:

Where are my mistakes?

Thaks a lot

You have two kinds of errors. This one:

Error from server (AlreadyExists): error when creating "install/cluster-operator/020-ClusterRole-strimzi-cluster-operator-role.yaml": clusterroles.rbac.authorization.k8s.io "strimzi-cluster-operator-namespaced" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/021-ClusterRole-strimzi-cluster-operator-role.yaml": clusterroles.rbac.authorization.k8s.io "strimzi-cluster-operator-global" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/021-ClusterRoleBinding-strimzi-cluster-operator.yaml": clusterrolebindings.rbac.authorization.k8s.io "strimzi-cluster-operator" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/030-ClusterRole-strimzi-kafka-broker.yaml": clusterroles.rbac.authorization.k8s.io "strimzi-kafka-broker" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/030-ClusterRoleBinding-strimzi-cluster-operator-kafka-broker-delegation.yaml": clusterrolebindings.rbac.authorization.k8s.io "strimzi-cluster-operator-kafka-broker-delegation" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/031-ClusterRole-strimzi-entity-operator.yaml": clusterroles.rbac.authorization.k8s.io "strimzi-entity-operator" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/032-ClusterRole-strimzi-topic-operator.yaml": clusterroles.rbac.authorization.k8s.io "strimzi-topic-operator" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/033-ClusterRole-strimzi-kafka-client.yaml": clusterroles.rbac.authorization.k8s.io "strimzi-kafka-client" already exists
Error from server (AlreadyExists): error when creating "install/cluster-operator/033-ClusterRoleBinding-strimzi-cluster-operator-kafka-client-delegation.yaml": clusterrolebindings.rbac.authorization.k8s.io "strimzi-cluster-operator-kafka-client-delegation" already exists

Means exactly what it says - you are trying to create a resource which already exists. Probably because you or someone else using your cluster already created it. You can for example use kubectl replace -f to replace the resources. But ideally if you have shared cluster you should know who created these and why as you might overwrite someone else's resources.

The second error:

Error from server (Invalid): error when creating "install/cluster-operator/060-Deployment-strimzi-cluster-operator.yaml": Deployment.apps "strimzi-cluster-operator" is invalid: spec.template.spec.containers[0].env[0].valueFrom: Invalid value: "": may not be specified when `value` is not empty

Again means exactly what it says. You broker the YAML file probably when editing the namespace. So you need to fix it. Without seeing the complete YAML file, I cannot be more specific than the error message is.

Ok, great. It looks like you configured the environment variable incorrectly. You have there this:

            - name: STRIMZI_NAMESPACE
              value: my-kafka-project
              valueFrom:
                fieldRef:
                  fieldPath: metadata.namespace

But it has to be only this:

            - name: STRIMZI_NAMESPACE
              value: my-kafka-project

[MrPallaBall]

So the guide is incorrect.
https://strimzi.io/docs/operators/latest/quickstart.html#proc-install-product-str

Edit the install/cluster-operator/060-Deployment-strimzi-cluster-operator.yaml file and set the STRIMZI_NAMESPACE environment variable to the namespace my-kafka-project.

# ...
env:
- name: STRIMZI_NAMESPACE
  value: my-kafka-project
# ...

It means to delete what I have by default and add my value as you described

Thanks

[scholzj]

TBH, so far everyone understood correctly what does it mean and what does need to be replaced. But if you think it should be more clear, feel free to open an issue or PR with some suggestion how would you expect it.

[MrPallaBall]

Sorry @scholzj,
but if I follow a quickstart guide line and the software doesn't start quickly there are some problems in guide line.

Now I edited the configuration as you described and my pod is in pedding status and I cannot view any log:

kubectl logs deployment.apps/strimzi-cluster-operator
Error from server (NotFound): deployments.apps "strimzi-cluster-operator" not found

I'll continue with the chapter 2.4 Creating a cluster and if there are some problems I'll write here all

[scholzj]

but if I follow a quickstart guide line and the software doesn't start quickly there are some problems in guide line.

Then please do what I suggested help make the Quickstart guide better.

Now I edited the configuration as you described and my pod is in pedding status and I cannot view any log:

kubectl logs deployment.apps/strimzi-cluster-operator
Error from server (NotFound): deployments.apps "strimzi-cluster-operator" not found

Then you would need to share the status of the deployments, the events and the pods to figure out why is it in Pending status.
