  2. At 2:40 you say it's better to create a namespace with a config file, but the file shown is for a ConfigMap (which uses a namespace)
    Is that a mistake ?

  3. Great video on the specific topic for sure, thanks for that.. But moreover its a great demo how tech videos should be done without much fuss & straight to the point and actual problem.. Hats off to that approach.

  4. Great video!. I am not able to install kubectx on ubuntu 18. Getting Unable to locate package kubectx.

  5. Hi Nana, I have a question. If I have 3 worker nodes, can I set affinity of a namespace to particular 2 worker nodes? This requirement came to me to segregate 2 projects with different cost approvals.

  6. Ive gone through so many of your videos regarding kubernetes, and they have been exceptionally helpful, especially for a young dev ops engineer. Thank you!!

  7. Can we create ephemeral namespaces ? if namespace A is in use and in high load scenario we can spawn Namespace B with same set of resources using by A

  8. Its very nice and comprehensive video about namespaces.
    One use case of namespace is to organize the Objects/Resources.
    Labels are also used to categorized and organized the Resources/Objects so what is the difference between namespace and labels for that specific use case.

  9. Hi Nana. Thank you for you videos! What do you think about using Rancher? With Rancher you can separate namespaces in different projects.
