A decade on and despite success among telcos and internal IT departments, OpenStack is now being mentioned in the same breath as Kubernetes â just not in a good way. There are several projects that automate deploying Kubernetes on top of OpenStack, like OpenShift, OpenStack Magnum, KubeSpray, and Airship. The official document about how to create a single control-plane cluster can be found from the Creating a single control-plane cluster with kubeadm documentation. In fact, those guiding the project are looking at a future where Kubernetes could replace OpenStack and VMware as the basis for cloud-native infrastructure. The OpenStack cloud provider uses the instance name (as determined from OpenStack metadata) as the name of the Kubernetes Node object. In this config we specify to use an external OpenStack cloud provider, and where to find its config. This guide describes how to simply stand up a multinode Kubernetes cluster via the OpenStack-Helm gate scripts, which use KubeADM and Ansible. Note that the instance name â¦ Node Name. Submit YAML â¦ Today, the OpenStack foundation made it even easier for you deploy and manage clusters of Docker containers on OpenStack clouds by including Kubernetes in its Community App Catalog. OpenStack supports the largest number of enterprise storage and networking systems today, and running Kubernetes with OpenStack allows you to seamless integrate containers into your environment. Rather, they could work together to deliver greater value to both service consumers and operators. The controller communicates with Kubernetes APIs and Cinder APIs to create/attach/detach/delete Cinder volumes. If Kubernetes wants to attach a persistent volume to a pod, it can find out which OpenStack VM the pod is running on from the mapping, and attach the underlying OpenStack volume to the VM accordingly. This post has been translated and edited for context with permission -- originally published on the Yahoo! If you are running on Rackspace public cloud, you can use the included heat template and script to set up an appropriate ssh tunnel: Hi folks, I've set up a single openstack "stein" node on rather beefy hardware (HPE DL380G7, 128GB RAM, 24 cores, 1,5TB Raid-6) in order to experiment with terraform & kubernetes on openstack. Mihaela Constantinescu will also be at the Summit in Berlin. Then we can create a PVC with this class.
