有旧版本的谷歌云平台工具：Docker

Question

After updating gcloud I get this warning, but how do I do it(Should I remove Docker)?

WARNING:   There are older versions of Google Cloud Platform tools on your system PATH.
  Please remove the following to avoid accidentally invoking these old tools:

  /Applications/Docker.app/Contents/Resources/bin/kubectl

I have this in my.zshrc:

# The next line updates PATH for the Google Cloud SDK.
if [ -f '/Users/<NAME>/google-cloud-sdk/path.zsh.inc' ]; then source '/Users/<NAME>/google-cloud-sdk/path.zsh.inc'; fi

# The next line enables shell command completion for gcloud.
if [ -f '/Users/<NAME>/google-cloud-sdk/completion.zsh.inc' ]; then source '/Users/<NAME>/google-cloud-sdk/completion.zsh.inc'; fi

[ -f ~/.fzf.zsh ] && source ~/.fzf.zsh

Answer 1

TLDR

/usr/local/bin/kubectl is a link installed by Docker: ls -l /usr/local/bin/kubectl => /usr/local/bin/kubectl -> /Applications/Docker.app/Contents/Resources/bin/kubectl . Removing the link has no side effects and solves the conflict:

rm /usr/local/bin/kubectl

Justification

The conflict is with the Docker-provided version of kubectl so it makes sense to check what Docker docs have to say about it. https://docs.docker.com/docker-for-mac/#kubernetes

Extract:

In Docker Desktop for Mac 17.12 Edge (mac45) and higher, and 18.06 Stable (mac70) and higher, a standalone Kubernetes server is included that runs on your Mac, so that you can test deploying your Docker workloads on Kubernetes.

The Kubernetes client command, kubectl , is included and configured to connect to the local Kubernetes server.

....

If you installed kubectl with Homebrew, or by some other method, and experience conflicts, remove /usr/local/bin/kubectl .

Answer 2

This happens because docker-for-mac installs a bin for kubectl, and gcloud-sdk also installs another bin with gcloud components install kubectl .

My recommendation is to uninstall kubectl as component from gcloud, overwrite the symlink from docker-for-mac, and only use the homebrew installed bin.

Try this commands:

gcloud components remove kubectl

brew install kubernetes-cli

brew link --overwrite kubernetes-cli

Answer 3

Here is my case you can refer to. After running gcloud components update , I got this warning:

WARNING: There are older versions of Google Cloud Platform tools on your system PATH. Please remove the following to avoid accidentally invoking these old tools:

/usr/local/Cellar/kubernetes-cli/1.10.2/bin/kubectl

I check this tool using brew list

☁  issue [master] brew list
coreutils       gdbm            git-lfs         icu4c           kops            kubectx         libpng          mtr             openssl         python@2        sqlite          tree            wxmac
erlang          geoip           git-redate      jpeg            kube-ps1        kubernetes-cli  libtiff         node            pcre            readline        telnet          watchman

After reading the doc . I decided to uninstall kubernetes-cli and its dependencies kops , kube-ps1 , and kubectx to avoid the conflicts.

☁  issue [master] brew uninstall kops kube-ps1 kubectx
Uninstalling /usr/local/Cellar/kops/1.9.0... (5 files, 129.8MB)
Uninstalling /usr/local/Cellar/kube-ps1/0.6.0... (6 files, 29.0KB)
Uninstalling /usr/local/Cellar/kubectx/0.5.0... (12 files, 27.8KB)
☁  issue [master] brew uninstall kubernetes-cli
Uninstalling /usr/local/Cellar/kubernetes-cli/1.10.2... (178 files, 52.8MB)
☁  issue [master] gcloud components update

All components are up to date.

This warning is gone.

我刚刚进入 Docker 文件的 bin 文件夹并将 kubectl 移到垃圾箱。

Answer 5

Do echo $PATH and check which folder takes precedence. In my case it is like .../Users/myname/google-cloud-sdk/bin:/usr/local/bin:/usr/bin:... . Here the kubectl in gcloud is actually before the kubectl from Docker Desktop (which is in /usr/local/bin/kubectl ) so there is no problem. If this is also your case you don't need to do anything.

Of course, if you want to completely remove confusion you can just delete the link /usr/local/bin/kubectl -> /Applications/Docker.app/Contents/Resources/bin/kubectl , or rename it.

Update:

In the recent docker desktop releases they actually provided another link /usr/local/bin/kubectl.docker -> /Applications/Docker.app/Contents/Resources/bin/kubectl to differentiate it from other kubectl so it is not a bad idea to just simply delete the link /usr/local/bin/kubectl -> /Applications/Docker.app/Contents/Resources/bin/kubectl
