Triage for current milestone

Getting the board ready

Check for what's missing from the board

Open up Project board https://github.com/orgs/kubernetes/projects/8
Click "Add Cards"
Drag everything to Backlog

Find items on SIG-Windows project missing current milestone

Open https://github.com/kubernetes/kubernetes/issues?q=is%3Aopen+label%3Asig%2Fwindows+no%3Amilestone+project%3Akubernetes%2F8

kubectl create -f iis-multi.yml
Log into the node

I can see the three containers running - pause, iis and windowswebserver. If I do a docker exec ... tasklist on each one, the processes listed are separate.

docker ps |select-string p7rm7

This is a brief brain-dump of the investigations I've done into how to make Kubernetes easier to setup along with some options suggested by others in SIG-Windows.

Getting binaries on the machine

aks-engine set precedence of putting things in c:\k. Is that the best decision? Should executables, logs and config be separated and ACLd more strongly?

Options:

MSI - would need to be built along with binaries. Not useful for configuration management & transitions though

Here's what I tried after reading https://github.com/kubernetes/community/blob/master/contributors/devel/bazel.md

sudo apt install golang
export GOPATH=~/go
go get k8s.io/kubernetes/vendor/github.com/bazelbuild/bazel-gazelle/cmd/gazelle
go install k8s.io/kubernetes/vendor/github.com/bazelbuild/bazel-gazelle/cmd/gazelle
hack/update-bazel.sh # this returned some errors, but the next step still seemed to work
make bazel-build # this failed running out of disk space for me

Setting up a Multi-Arch, Multi OS cluster

I wanted to build a home lab to get some experience with how Kubernetes works in a multi-architecture, multi-OS environment. Here's the worklog. I'll probably turn it into a blog later :)

Setting up a Multi-Arch, Multi OS cluster
- First node - ODroid HC-1
  - Initial setup of the ODroid
ODroid frequency scaling (optional)

Tools

ACS-Engine - Getting started guide for Windows clusters is usually the right place to start. I did a lot of last minute work to move this forward to Windows Server 2019. Right now there isn't a known-good release that's been fully tested with Windows Server 2019, so I'll share the one I used

Helm - no changes

Draft - no changes
