This script creates the file ".kube/config" in the home folder of the
logged in user and sets/replaces the value of variable KUBECONFIG inside
file ".profile". Currently, the main use case that involves this K8S
config file is the K8S authentication through OIDC token.
Test Plan:
PASS: Deploy an IPv4 AIO-SX with an image containing this change and
verify that the script is available at "/usr/local/bin/kubeconfig-setup"
with permissions "-r-xr-xr-x", owner root, group root. Setup OIDC app,
create local linux user "tu1" and create a ClusterRoleBinding in K8S for
tu1 user as cluster-admin.
PASS: Using the deployed AIO-SX, SSH to the controller using "tu1".
Execute "kubeconfig-setup; source .profile", verify that the file
"/home/tu1/.kube/config" was created, execute "oidc-auth" and then
"kubectl get pods -A -v=6", verifying in the output that the file
"/home/tu1/.kube/config" is being used by kubectl.
PASS: Using the deployed AIO-SX, edit the file ".profile" of "tu1"
replacing 'export KUBECONFIG="/home/tu1/.kube/config"' by "export
KUBECONFIG="invalid_value"' and then repeat the previous test, that will
be successful. After, verify that KUBECONFIG is set to 'export
KUBECONFIG="/home/tu1/.kube/config"' in ".profile".
PASS: Using the deployed AIO-SX, SSH again to the controller using "tu1"
and just execute "kubectl get pods -A -v=6", verifying in the output
that the file "/home/tu1/.kube/config" is being used by kubectl.
PASS: Repeat all tests above using an IPv6 AIO-SX.
