az aks mesh enable --name $env:CLUSTER --resource-group $env:RESOURCE_GROUP

returns

Hi, @SompoMHeckmann! Thank you for your feedback.

I was able to successfully run az aks mesh enable --name $CLUSTER --resource-group $RESOURCE_GROUP on an existing cluster without receiving an error message. I then created another cluster and ran the az aks mesh enable --name $CLUSTER --resource-group $RESOURCE_GROUP --revision 'asm-1-19' command on it, which was also successful. As it stands, I don't see an issue with the documentation itself.

I feel like I might be missing a bit of context here, so I'd appreciate if you could provide a bit more clarity. From my understanding, your running of az aks mesh enable --name $CLUSTER --resource-group $RESOURCE_GROUP (without the revision parameter) returned a revision-related error message? Is that correct? Did you try to run az aks mesh enable --name $CLUSTER --resource-group $RESOURCE_GROUP --revision 'asm-1-19' afterward?

Thank you!

That is correct. I tried to install and received the error message. I had az preview installed a while back, but had it removed while attempting. Thinking that may be the cause, I reinstalled it and installed istio successfully with az aks mesh enable --name $CLUSTER --resource-group $RESOURCE_GROUP. Then I uninstalled istio and AK preview. Tried to install istio again with the same error message. I then added the revision and successfully installed. Researching the error, I came across another user having the same issue on https://serverfault.com/questions/1155856/azure-istio-revision-asm-1-17-is-not-supported-by-the-service-mesh-add-on/1155942#1155942 .

This was done from Azure Cloud Shell using powershell.

I was able to run az aks mesh disable --name $env:CLUSTER --resource-group $env:RESOURCE_GROUP and az aks mesh enable --name $env:CLUSTER --resource-group $env:RESOURCE_GROUP successfully today.
