Instead, I ended up configuring a static route for the (large) minikube cluster IP range on my router (or locally with route). How to reproduce it (as minimally and precisely as possible): Start minikube using no vm-driver option and then without deleting machine try deploying using xhyve. When using Hyper-V, a virtual machine runs in the background which can be managed from the Hyper-V manager. Windows Subsystem for Linux 2 sports an actual Linux kernel, supporting real Linux containers and Docker. Make sure to run the following command as a user instead of root so the configuration will be stored for the user instead of root. In our tutorial, instead of using a virtual network interface on the host, we can leverage a Minikube option that is available when using the hyperv driver: --hyperv-virtual-switch. Complete this Guided Project in under 2 hours. Minikube runs within the Hyper-V VM. Use minikube start to boot up the cluster. Prerequisites You can use Minikube to run Kubernetes (k8s) on your local machine. most of tutorials about ingress (networking, not network policy) which I saw on internet is based on minikube. It is better to create a service using kubectl expose deployment_name --port=3000 --type=NodePort --name=service_name since it saves you the hassle of writing a yaml . We now have two environments that can be used instead of Docker Desktop: minikube and multipass. If you prefer to use bash instead of the windows command line you can install the Windows Subsystem for Linux (WSL). Instead it uses a "hypervisor", e.g. It is perfect for people that are using multiple OS machines and have some basic familiarity with Kubernetes and Docker. As a bonus you can also run Kubernetes pods :D For only testing purposes you can use port-forwarding. We are going to deploy and run the Python REST API on MInikube in this article. Instead of stopping the Kubernetes cluster and Hyperkit VM, we can pause it. Granting access to the docker socket grants privileges equivalent to the root user. After deleting my Minikube cluster and creating new one, I noticed that the above approach stopped working. Show activity on this post. These examples will use minikube, but production-ready Kubernetes setups should work very similarly. Minikube can function as a fair replacement for Docker Desktop without too much additional work. The mi n ikube docker daemon needs to be used instead of the host docker daemon, this can be done by running: $ eval $(minikube docker-env) To view the resources that exist on the local cluster, the minikube dashboard will be utilized using the command: $ minikube dashboard You can login to this VM with user root. I created a new VM called "kube2" and installed contianerd, kubeadm, kubectl, and kubelet, same as before.Now instead of using the kubeadm init command, we'll use the kubeadm join command we saved from the previous kubeadm init.. Now let's check it out, listing the nodes back at the main host with kubectl get nodes. Be sure to run it as administrator.. With Minikube, if I shutdown the cluster (and the Hyperkit VM) with minikube stop, it removes the Docker images and all persistent volumes. kubeadm. Run a quick example: create a Pod which prints a message. When creating cluster, instead of specifying the cluster imperatively, the configuration (e.g. minikube is a Kubernetes SIGs project and has been started more than three years ago. Here's how: If you already have Docker Desktop installed, remove it and reboot. I used KVM2, and you can also use Virtualbox. minikube is local Kubernetes, focusing on making it easy to learn and develop for Kubernetes.. Why write an article on installing minikube on Ubuntu with Windows Subsystem Linux (WSL) 2 backend?
