The intention is that if supply a dedicated kubeconfig location for the k3s-ansible controlled clusters, we don't do any merging or overriding. |

In order for this to not affect user defined kubeconfigs, we need to check and see if the kubeconfig is still equal to our variable default.

We also need to override the default kubeconfig at the end

mv ${TFILE} {{ kubeconfig }} |

mv ${TFILE} ~/.kube/config |
There is also the block which can cause a full overwrite. |
Changes
Since the existing config file was not in scope, the commands did not perform anything.
To fix it, I include the existing kubeconfig path in KUBECONFIG variable such that the YAML contents are merged when it prints out via
kubectl config view --flatten
Also, replacing keyword "default" with ansible variable
kube_config
can also help replace thecurrent-context
in the kubeconfig file.Linked Issues
