I want to upgrade the kubectl client version to 1.11.3.
I executed brew install kubernetes-cli but the version doesnt seem to be updating.
Install specific version of kubectl
curl -LO https://storage.googleapis.com/kubernetes-release/release/
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)
