Step 1: Install Kubernetes Management Tools If you have a clean OS installation on your bare metal server instance, install dependencies and tools necessary for a Kubernetes cluster deployment. If you don't know the configuration "After the incident", I started to be more careful not to trip over things. When setting up a Kubernetes cluster, the installation of a network plugin is mandatory for the cluster to be operational. The istio-cni plugin is expected to work with any hosted Kubernetes leveraging CNI plugins. Make sure the CNI configuration file for the network add-on is in place under /etc/cni/net.d [root@node1]# ls /etc/cni/net.d 10-flannel.conf Run ifconfig to check docker, flannel bridge and virtual interfaces are up as mentionned here on github https://github.com/kubernetes/kubernetes/issues/36575#issuecomment-264622923 In the Select a dashboard section, choose Choose Add to dashboard to finish. documentation for that Container Runtime, for example: For specific information about how to install and manage a CNI plugin, see the documentation for The plugin is responsible for allocating VPC IP addresses to Kubernetes nodes and configuring the necessary networking for pods on each node. Learn the internal working and setup for Kubernetes cni - EDUCBA It is simple, but not so functional. Perform a quick search across GoLinuxCloud.

Open an issue in the GitHub repo if you want to portmap I hope you have saved the kubeadm join command from the kubeadm init stage which we executed earlier. This tutorial provides a walkthrough of the basics of the Kubernetes cluster orchestration system. Here I have a YAML file for a simple nginx pod: Check the IP assigned to this Pod via Calico network: So the Pod has got the IP from our subnet 10.142.0.0/24 which we assigned while installing the Calico network in our Kubernetes Cluster. This allows the add-on to overwrite any existing custom settings.
