I am currently upgrading my terraform stack with azurerm from the version 1.x to the version 2.x.
I make all the changes from the terraform files, but when trying to apply the configuration, I am getting the following error:
default_node_pool: The Default Agent Pool “” was not found
After some investigation in a new deployed stack and the old one, I can see that the block
agent_pool_profile is existing in the old terraform state file, but has been replaced by
default_node_pool in the new terraform state file.
Which is also mentioned here https://www.terraform.io/docs/providers/azurerm/guides/2.0-upgrade-guide.html#removal-of-deprecated-fields-data-sources-and-resources
How can I upgrade my stack using k8s with that kind of changes? (I just hope I should not update the tfstate file manually )
Having the same issue trying to migrate from 1.x to 2.x. I’ve modified the block to
default_node_pool but appears that its still attempting to check for a
Defautl Agent Pool "" even though there’s a
name within the
Any advice on migrating?
I had identical issue. The problem was that my AKS cluster default nodepool had mode USER instead of SYSTEM. Old output from az aks nodepool list
Name OsType VmSize Count MaxPods ProvisioningState Mode
------- -------- --------------- ------- --------- ------------------- ------
default Linux Standard_DS4_v2 0 110 Succeeded User
So the fix was to change the mode to SYSTEM
az aks nodepool update -g GROUP--cluster-name CLUSTER_NAME -n default --mode system
and then everything worked
Thanks Bud, This solved the issue.
I was really hoping that this would resolve my issue but i get new error when running the az aks nodepool update command
“BadRequestError: Operation failed with status: ‘Bad Request’. Details: AgentPool APIs supported only for clusters with VMSS agentpools. For more information, please check https://aka.ms/multiagentpoollimitations”
might be useful for folks who are wondering , how to check if your cluster is User/SYSTEM
az aks nodepool show --cluster-name name -g resource-group --name default --output table
