VMware vSphere VM iPXE Boot without DHCP
Network booting operating systems isn’t a new concept and has been around for years. Bare metal deployments are typically where network booting is …
Containers has been on a steady march to replace virtual machines as the primary computing model for which applications are developed. The use of containers provide a self-contained means of application deployment that is faster to develop against.
Containers with all of their benefits still need to run on an underlying operating system. That operating system often runs on a virtual machine or instance.
There are a number of operating systems that are purpose built for simply running containers. Fedora/Red Hat CoreOS, Flatcar Linux, VMware Photon and others.
Stateless Configuration
In this example we’ll walk through booting
