I have a development cluster running in Azure with a single node to save costs. Some new container-based services require the ManagedIdentityTokenService and I'm trying to add it according to the documentation here but are prevented by ARM templates not allowing updates to single-node clusters.
Is there some workaround to recreating the entire cluster which is a bit of work? I don't care if the cluster is down while it's updating.
(The production cluster is running on five nodes so it won't be an issue upgrading there.)
The error message:
{
"error": {
"code": "SingleNodeClusterUpdateNotAllowed",
"message": "Single node cluster update not allowed. Updates are allowed for clusters having node count equal or greater than 3.",
"details": []
}
}
Unfortunately no. You'll need to delete and recreate the cluster, instead of trying to update an existing one.
If you have a development cluster, where more than one Service Fabric node is on a single physical or virtual machine, you must re-create the cluster with the new version.
