This is a list of Docker Desktop for Mac development builds which contain mutagen. These are based on Edge, but may contain unexpected bugs. They should be used for testing the Mutagen feature rather than for production work.

2020-07-14: development snapshot: https://desktop-stage.docker.com/mac/edge/46638/Docker.dmg

Exclude files from a mutagen sync based on the .dockerignore file.
Flush around docker exec as well as docker run for more reliable scripting.
Fix a bug which could result in duplicates in the list of synchronised directories.
Allow the sync to be bypassed by using :consistent or :cached. In particular this means if you want the previous :delegated behaviour before mutagen, switch to :cached. This

vsock notes

about vsocks

Vsocks are a means of providing socket communication (either stream or datagram) directly between VMs and their host operating system. The host and each VM have a 32 bit CID (Context IDentifier) and may connect or bind to a 32 bit port number. Ports < 1024 are privileged ports.

Vsock communication between VMs does not seem to work.
Only one vsock device per VM is supported.

Kubernetes Master Nodes Backup for Kops on AWS - A step-by-step Guide

For those who have been using kops for a while should know the upgrade from 1.11 to 1.12 poses a greater risk, as it will upgrade etcd2 to etcd3.

Since this upgrade is disruptive to the control plane (master nodes), although brief, it's still something we take very seriously because nearly all the Buffer production services are running on this single cluster. We felt a more thorough backup process than the currently implemented Heptio Velero was needed.

To my surprises, my Google searches didn't yield any useful result on how to carry out the backup steps. To be fair, there are a few articles that are specifically for backing up master nodes created by kubeedm but nothing too concrete for `kop
