Using colima and Docker Engine on Apple Silicon (M1 Chip)

This tutorial uses Homebrew to install colima and Docker.

It was tested on Apple MacBook Pro (13-inch, M1, 2020) 8G and macOS Monterey version 12.1 (21C52).

Uninstall any Docker version

Make sure you have fully uninstall any versions of Docker. You can check using:

vjt

As painless does not support \n, as per https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-literals.html you have to get ASCII newline 0x0a, cast to char and then cast to string https://www.elastic.co/guide/en/elasticsearch/painless/current/painless-casting.html#character-string-casting

So to split your string in Painless on newline you have to

_source['message'].splitOnToken((String)(char)0x0a);

And yes that sounds retarted.

This is my current "dev workflow" for quickly bootstrapping an Spring app on a Kubernetes cluster. The general approach is polyglot but you will need to use something like https://buildpacks.io instead of Jib to support non-JVM projects

This example uses skaffold and kapp so you will need to install from https://skaffold.dev/docs/install/ & https://k14s.io/ You will also need kubectl installed and a Kubernetes cluster targetted. You can use Minikube, Kind or K3S for lightweight, local Kubernetes environment

Introduction

Did you know that you can have multiple helm tillers running in a cluster?
This may actually be useful to us for both security as well as isolating what our cluster ops team does from what our customers can do.

Background

Current Helm Access Control

Helm security is such that "If you can talk to tiller, you can use that tiller" To be able to contact tiller, one needs to be able to create a pod in the namespace tiller resides in. Otherwise you will get an error message like:
