One of the challenges that organizations and administrators need to be familiar is installing patches/updating the Red Hat OpenShift infrastructure. There are two ways to update a cluster: using Web Console or CLI. With both methods, you can achieve the same result and update is smooth.
Docker is an open-source platform that allows you to develop, build, deploy, test, manage and run applications in containers. Containers are standardized units that include libraries, system tools, code, and runtime to run software or application.
etcd is a consistent, open-source and distributed key-value store used in Kubernetes to backing all cluster resources like: configuration data, state data or metadata.
Regular backups of etcd database are crucial habit for Kubernetes clusters. Red Hat OpenShift has build-in mechanism to achieve that.
Red Hat OpenShift Container Platform is a container Kubernetes platform. With OpenShift, organizations can automate application deployment and management.
RH Openshift can be run in a private cloud infrastructure directly on the bare metal servers and on the virtualization platforms like VMware, Nutanix or Openstack. Also, it’s possible to install OCP in the public clouds like AWS, Azure, GCP or Alibaba.
VMware Aria Operations is a tool for monitoring infrastructure, virtual machines, predict resource demands or costs and more. Most of you want to visualize, provide logs and information from the VMware vCenter Server.
In some cases we need to reinstall ESXi host. To avoid time consuming setting up servers, we can quickly backup and restore host configuration. To achieve this, there are three possible ways: ESXi command line, vSphere CLI or PowerCLI
In this article I will show how backup and restore host configuration data using ESXi command line.
