Purpose of this cluster was to build an AKS cluster for the express purpose of using it to setup a Cilium ClusterMesh with my Free Tier GKE cluster.
I chose AKS because like Google, Azure also has a free tier offering for their managed Kubernetes service that is pretty decent.
One of the Terraform outputs will include the command to install Cilium and it will look something similar to the one shown below. The cluster.id needs to be unique across clusters in your cluster mesh and hence I've based the Resource Group name on the variables, aks_cluster_name_prefix and cluster_id to help ensure uniqueness.
- example:
cilium install \
--version 1.14.3 \
--set cluster.name="playground-aks-6" \
--set cluster.id=6 \
--set azure.resourceGroup="playground-aks-6-rg" \
--set ipam.operator.clusterPoolIPv4PodCIDRList='{10.100.0.0/18}'- example output:
