Via Ivan Pepelnjak, I was pointed to Jon Langemak’s in-depth discussion of working with Linux VRFs. The first is a post on Cilium and F5 load balancer integration , while the second discusses implementing Kubernetes network policies with Cilium and Linkerd. Alessandro Perilli has a very lengthy article on NoOps.

Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). Ivan Pepelnjak has a great article that tries to get to the kernel of truth in the middle of the intent-based networking hype. John Kozej walks through how to configure vCenter HA using the NSX load balancer.

Mirantis published an article discussing a framework they built for bare-metal provisioning with OpenStack that allows OpenStack to place workloads onto bare-metal nodes instead of onto a hypervisor. I don’t have anything for this area this time around, but I’ll stay alert for articles to add next time. Servers/Hardware.

OS X provides an SSH agent by default, but on Linux systems you will probably have to manually run an SSH agent and add the appropriate SSH key: eval `ssh-agent -s` ssh-add ~/.ssh/keyfile.pem. This article was originally posted on blog.scottlowe.org. Linux CLI Docker OSS' ssh/keyfile.pem. Courteous comments are always welcome.
