Create the Namespace in Kubernetes

 

Create the Namespace in Kubernetes

when trying to create the ConfigMap in that namespace. You need to create the namespace first before creating resources within it. Here's how you can do it:

1. Create the Namespace:

   Run the following command to create the "datacenter" namespace:

#   kubectl create namespace datacenter

2. Create the ConfigMap:

   After creating the namespace, run the ConfigMap creation command:

#   kubectl create configmap time-config --from-literal=TIME_FREQ=7 -n datacenter

  

This sequence of commands should first create the necessary namespace and then create the ConfigMap in that namespace. You can then proceed with the other steps to create the pod and associated resources as described in the previous response.
