How to upgrade kubectl client version

So, to upgrade kubectl on mac:

brew upgrade kubectl

Then you 'll probably need:

brew link --overwrite kubernetes-cli

I had installed kubectl using google-cloud-sdk. So in my path kubectl was pointing to this location. That is why the version did not update. Kubectl got updated after I removed that from the path.

If you have installed it with brew, you can just run brew upgrade kubernetes-cli.

Install specific version of kubectl

curl -LO https://storage.googleapis.com/kubernetes-release/release/<specific-kubectl-version>/bin/darwin/amd64/kubectl

For your case if you want to install version v1.11.3 then replace specific-kubectl-version with v1.11.3

Then make this binary executable

chmod +x ./kubectl

Then move this binary to your PATH

sudo mv ./kubectl $(which kubectl)
