Dawn Chen, TL for SIG-Node and the Google Kubernetes Engine node team, joins Craig and Adam this week. She has worked on containers and container schedulers since 2007 - not a typo. We also bring you the news, in part from the echo chamber of Google Cloud Summit in Sydney.
Do you have something cool to share? Some questions? Let us know:

Process containers (later ‘cgroups’):

The first submission of containers to the Linux kernel
Early coverage of process containers
Paul Menage’s 2007 paper “Adding Generic Process Containers to the Linux Kernel”
Dawn’s first job: tracking processes. Each job had its own GID - she would use netlink connection tracking to map processes and threads to GIDs, and, using procfs, figure out CPU and memory usage.
Dawn’s second job: adjusting CPU usage using nice
Today we just use memcg

How did we get to CRI?

rktnetes was released with Kubernetes 1.3
Hyper_ containers (now Kata Containers)
LXC and LXD
kubevirt for running VMs instead of containers
OCI
CRI was released with Kubernetes 1.5
containerd and CRI-O


Container RuntimeHandler, so some pods can run with one runtime and some with another
