Namespaces not found
13,636
Solution 1
I had previously created two contexts and my minikube cluster was set to still be in the n2
context. I deleted the context, re-ran the command and it worked.
Solution 2
Add namespace: n3 to deployment spec
Solution 3
In my case I created context and set --namespace to not existing one, the solution was switch namespace only using the kubectl commands:
kubectl config set-context --current --namespace=<namespace>
You can check if in your situation is the same problem using:
kubectl get svc -o wide
kubectl describe sa default | grep Namespace

I see the following error when I run my deployment:
Error from server (NotFound): error when creating "n3deployment.yaml": namespaces "n2" not found
My n3deployment.yaml has no reference to n2?
Step By Step
- Ensure everything is empty
c:\temp\k8s>kubectl get pods No resources found. c:\temp\k8s>kubectl get svc No resources found. c:\temp\k8s>kubectl get deployments No resources found. c:\temp\k8s>kubectl get namespaces NAME STATUS AGE default Active 20h docker Active 20h kube-public Active 20h kube-system Active 20h
- Create files
n3namespace.yaml apiVersion: v1 kind: Namespace metadata: name: n3 n3service.yaml apiVersion: v1 kind: Service metadata: name: my-app-n3 namespace: n3 labels: app: my-app-n3 spec: type: LoadBalancer ports: - name: http port: 80 targetPort: http protocol: TCP selector: app: my-app-n3 n3deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: my-app-n3 labels: app: my-app-n3 spec: replicas: 1 selector: matchLabels: app: my-app-n3 template: metadata: labels: app: my-app-n3 spec: containers: - name: waiter image: waiter:v1 ports: - containerPort: 80
- Apply configuration
c:\temp\k8s>kubectl apply -f n3namespace.yaml namespace "n3" created c:\temp\k8s>kubectl apply -f n3service.yaml service "my-app-n3" created c:\temp\k8s>kubectl apply -f n3deployment.yaml Error from server (NotFound): error when creating "n3deployment.yaml": namespaces "n2" not found
I used to have a namespace called
n2
but, as you can see, it no longer exists.
