I am trying to setup spinnaker with kubernetes and getting an error: user cannot list namespace.
I don't have access to list namespace in cluster scope. Is it possible to set up and apply hal configuration without access to list namespaces at cluster scope? if yes, please let me know the steps.
Below I mention the command out for reference:
hal deploy apply
+ Get current deployment
Success
- Prep deployment
Failure
Problems in default.provider.kubernetes.my-k8s-account:
! ERROR Unable to communicate with your Kubernetes cluster: Failure

? Unable to authenticate with your Kubernetes cluster. Try using
kubectl to verify your credentials.

Short answer: no.
You can try to get your admin to give you access to a ClusterRole
+RoleBinding
that has access to namespaces read.
Something like this:
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: namespace-reader
rules:
- apiGroups: [""]
resources: ["namespaces"]
verbs: ["get", "watch", "list"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: read-all-namespaces
subjects:
- kind: User
name: your-user
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
name: namespace-reader
apiGroup: rbac.authorization.k8s.io
You can do it without ClusterRole. Tested, works as expected.
See instruction.
Configure Spinnaker to install in Kubernetes
Important: This will by default limit your Spinnaker to deploying to the namespace specified. If you want to be able to deploy to other namespaces, either add a second cloud provider target or remove the --namespaces
flag.
Use the Halyard hal command line tool to configure Halyard to install Spinnaker in your Kubernetes cluster
hal config deploy edit \
--type distributed \
--account-name ${ACCOUNT_NAME} \
--location ${NAMESPACE}
