Kubernetes Integration with Python-CGI
This time create webUI page as such that using normal English conversation your all commands can run in background.
Example — when we write ‘run deployment using httpd image’ then it run complete deployment command in backend.
Feature necessary -
👉 It can launch pods with specific name given by user.
👉 Run deployment using image and name given by user.
👉 Expose services on given user input port number.
👉 Scale the replica according to user need.
👉 Delete complete environment created.
👉 Delete specific resources given by user.
👉 Extra features related to k8s ( Optional)
