This is part of a series of posts about my experience working with OpenShift and CNV. In this post, I’ll look at how the recently released CNV 2.4 resolves some issues in managing virtual machines that are attached directly to local layer 2 networks In an earlier post, I discussed some issues around the management of virtual machine MAC addresses in CNV 2.3: in particular, that virtual machines are assigned a random MAC address not just at creation time but every time they boot.
This is the second in a series of posts about my experience working with OpenShift and CNV. In this post, I’ll be taking a look at how to expose services on a virtual machine once you’ve git it up and running. TL;DR Overview Connectivity options Direct attachment Using an OpenShift Service Exposing services on NodePorts Exposing services on cluster external IPso Exposing services using a LoadBalancer TL;DR Networking seems to be a weak area for CNV right now.
This is the first in a series of posts about my experience working with OpenShift and CNV (“Container Native Virtualization”, a technology that allows you to use OpenShift to manage virtualized workloads in addition to the containerized workloads for which OpenShift is known). In this post, I’ll be taking a look at the installation experience, and in particular at how restrictions in our local environment interacted with the network requirements of the installer.
