问题
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.
Client Version: version.Info{Major:"1", Minor:"10", GitVersion:"v1.10.7", GitCommit:"0c38c362511b20a098d7cd855f1314dad92c2780", GitTreeState:"clean", BuildDate:"2018-08-20T10:09:03Z", GoVersion:"go1.9.3", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.4", GitCommit:"bf9a868e8ea3d3a8fa53cbb22f566771b3f8068b", GitTreeState:"clean", BuildDate:"2018-10-25T19:06:30Z", GoVersion:"go1.10.3", Compiler:"gc", Platform:"linux/amd64"}
I'm trying to get the logs for a cell by running this command.
kubectl logs -l groupname/cell=my-cell --all-containers=true
This works in my VM which has client version 1.11.3. But in my mac it gives me an error saying --all-containers=true flag is not available for kubectl logs command.
回答1:
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)

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.
回答4:
To install OR upgrade the version of kubectl Server and Client on MacOS X is very easy if you follow the detailed install guide on the Kubernetes install page https://kubernetes.io/docs/tasks/tools/install-kubectl/#install-kubectl-on-macos
Hope it helps :)
