Helm: Incompatible versions between client and server
Like the OP, I had this error:
$ helm list
Error: incompatible versions client[v2.10.0] server[v2.9.1]
Updating the server wasn't an option for me so I needed to brew install a previous version of the client. I hadn't previously installed client[v2.9.1] (or any previous client version) and thus couldn't just brew switch kubernetes-helm 2.9.1
. I ended up having to follow the steps in this SO answer: https://stackoverflow.com/a/17757092/2356383
Which basically says
- Look on Github for the correct kubernetes-helm.rb file for the version you want (2.9.1 in my case): https://github.com/Homebrew/homebrew-core/search?q=kubernetes-helm&type=Commits
- Click the commit hash (78d6425 in my case)
- Click the "View" button to see the whole file
- Click the "Raw" button
- And copy the url: https://raw.githubusercontent.com/Homebrew/homebrew-core/78d64252f30a12b6f4b3ce29686ab5e262eea812/Formula/kubernetes-helm.rb
Now that I had the url for the correct kubernetes-helm.rb file, I ran the following:
$ brew unlink kubernetes-helm
$ brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/78d64252f30a12b6f4b3ce29686ab5e262eea812/Formula/kubernetes-helm.rb
$ brew switch kubernetes-helm 2.9.1
Hope this helps someone.
To upgrade your tiller version to the same version of the client, just run helm init --upgrade
NOTE: If you're trying to downgrade the server version to match your local client version, run the following instead:
helm init --upgrade --force-upgrade
