Overview

This document outlines the failure scenario when using the Kuma service mesh in Kubernetes mode with a Loft.sh vCluster. The Kuma demo app behaves correctly in bare k3s, Kind, minikube, and bare AWS k8s, and the Loft AWS k8 cluster directly, for certain.

• Install and configure Loft. It may be possible to sidestep this setup by using Kiosk directly, but I have not done so, nor does my use case warrant that.
• Create vcluster (k3s inside k8).
• Install Kuma control plane
• Apply kuma-demo app
• Observe issues

Make sure k3s is executable, it's a Linux only app right now and I'm on Mac 11.0.1 so:

brew cask install multipass

Execute the VM (deliberately large):

multipass launch --name k3s --mem 5G --disk 10G

Trails

Trails you wouldn’t run to from Ann Arbor

Note most of these all require passes to park (metropark vs. state park)

Potowami (Poto) - http://www.michigandnr.com/parksandtrails/Details.aspx?id=229&type=SPTR#map-tab Probably the most popular place to run trails, but also mountain bike in the area. It’s ~25 mins from Westside of Ann Arbor and is rather hilly/technical for the area.

Island Lake - http://www.michigandnr.com/parksandtrails/Details.aspx?id=462&type=SPRK Mostly flat like a pancake with very few hills, this is another popular spot to enjoy the woods, but without the hills to punish. It’s also an incredibly popular MTB spot for beginners.

var request = require('request')
var async = require('async')

var url = "https://yourapi"

// status codes and the number of results
var results = {200 : 0, 500: 0};

var requestIt = function(cb) {
    request(url, function (error, response, body) {

1. Install: https://github.com/julienXX/terminal-notifier
2. Have iterm2: https://www.iterm2.com/
3. In iterm2, setup a trigger on your "Profile" => "Advanced" => "Triggers", like 
https://www.evernote.com/l/AAX11ukjn5pDSYrbR54z_vNJuv-U6jyU6BAB/image.png

Where regexp is: "Deployment .+ for .+ on deployment id .*"
and params are "/usr/local/bin/terminal-notifier -title "Deployment finished" -message "\0"

4. That should do it. You can test it out by running: 
sleep 5 && echo "Deployment succeeded for Peach-API on deployment id d-GXY9RDCGB

var http = require('http');
http.createServer(function (req, res) {
        console.log("Got the request, but I'm not going to do anything about it, hahahahah");

}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
