After I have run helm list I got following error:
Error: incompatible versions client[v2.9.0] server[v2.8.2]
I did a helm init to install the compatible tiller version "Warning: Tiller is already installed in the cluster. (Use --client-only to suppress this message, or --upgrade to upgrade Tiller to the current version.)".
Any pointers?
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
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.
Another alternative, if changing the server version is not an option, is to use the helm installer script
The script lets you chose a specific version like so
./get_helm.sh -v v2.13.1
Another approach to using different versions through Docker.
https://hub.docker.com/r/alpine/helm
Example: list helm packages installed
docker run -it --rm \
-v ~/.kube/config:/root/.kube/config \
-v ~/.helm:/root/.helm alpine/helm:2.9.1 \
list
This is a long command; but it can be shortened with an alias
alias helm_2_9_1="docker run -ti --rm \
-v $(pwd):/apps -v ~/.kube/config:/root/.kube/config \
-v ~/.helm:/root/.helm alpine/helm:2.9.1"
And then the command is
helm_2_9_1 list
This answer is for who want to choose(downgrade) helm client version, and the brew install is not work.You can just manually install the binary file from here.
example:
you can unlink the current helm
brew unlink kubernetes-helm
choose and download the helm version you want in github helm------v2.8.2
unzip the file and put the helm unix executable binary file into /usr/local/bin directory
go to the directory you just downloaded
cd /Users/your_name/Downloads
unzip the file
gunzip -c helm-v2.8.2-darwin-amd64.tar.gz | tar xopf -
copy to the bin directory
cp darwin-amd64/helm /usr/local/bin
now you will see the right version of helm you want
helm version
This probably isn't the most advanced answer... but my team runs kubernetes clusters that already have tiller installed. While setting up a new laptop, I wanted my helm to match the tiller version, so I found it like this:
TILLER_POD=`kubectl get pods -n kube-system | grep tiller | awk '{print $1}'`
kubectl exec -n kube-system $TILLER_POD -- /tiller -version
Then I just used the normal helm install instructions from that release number (being on Linux, its basically just curl and unzip to /usr/local/bin).
If you are windows user and installed helm through choco, firstly go its folder (mine is C:\ProgramData\chocolatey) and delete helm.exe from bin folder.
Then, corresponding heml.exe file should be downloaded. By using the above comments, decide the location where you will download exe from. For instance, I used that path: https://get.helm.sh/helm-v2.14.3-windows-amd64.tar.gz
Finally extract the helm.exe from tar and move into choco bin folder. Of course, you can directly add this exe into the path.
I experienced same issue, but in my case I wanna only to upgrade Tiller to specific version (because helm client is running remotely).
So, error was:
Error: UPGRADE FAILED: incompatible versions client[v2.11.0] server[v2.9.1]
Accordingly to documentation I've run:
$ kubectl --namespace=kube-system set image deployments/tiller-deploy tiller=gcr.io/kubernetes-helm/tiller:v2.11.0
deployment.extensions/tiller-deploy image updated
