First, create a resource group to create the cluster in: Azure CLI Copy Open Cloudshell az group create -l <Region> -n <ResourceGroupName> Then create the cluster itself: Azure CLI Copy Open Cloudshell See kubeadm init section, then as Menionned by Jordan, on some environments you need to install RBAC, If you are still having issues check that, Make sure your cni plugin binaries are in place in /opt/cni/bin. Having created a cluster using Container Engine for Kubernetes (using either the Console or the API) and selected flannel overlay as the Network type, you can subsequently install Calico on the cluster alongside the flannel CNI plugin to support network policies.. For convenience, Calico installation instructions are included below. helper, IP Addresses Per Network Interface the version number of the add-on that you want to see the configuration Install a default network Our installation method requires that you first have installed Kubernetes and have configured a default network - that is, a CNI plugin that's used for your pod-to-pod connectivity. It also handles all the necessary IP routing, security policy rules, and distribution of routes across a cluster of nodes. For plugin developers and users who regularly build or deploy Kubernetes, the plugin may also need non-production cluster before updating the add-on on your production If you preorder a special airline meal (e.g. Confirm that the new version is now installed on your cluster. 0.4.0). To chose a different CNI provider, see the individual links above. provider for your cluster, Installing, updating, and uninstalling the AWS CLI, Installing AWS CLI to your home directory, Service in a variable.
