IdeaBot Local Dev Workflow with MINC and Tilt

2026-05-27T15:10:18Z by Showboat 0.6.1

This document demonstrates the local Kubernetes development workflow for IdeaBot using MINC (MicroShift in Container) and Tilt. The entire environment runs inside a Docker-in-Docker devcontainer — no cloud cluster required.

Prerequisites

The devcontainer comes with all tools pre-installed: Docker (via Docker-in-Docker), Helm, Tilt, MINC, and kubectl. Let's verify:

	FROM registry.access.redhat.com/ubi9:latest

	RUN rpm -i http://mirror.stream.centos.org/9-stream/BaseOS/x86_64/os/Packages/attr-2.5.1-3.el9.x86_64.rpm

	ADD script.sh /
	RUN chmod a+rx /script.sh

	CMD [ "/script.sh" ]

	#! /bin/bash

	set -e -o pipefail

	function usage {
	cat - <<USAGE
	Usage:
	$0 -n namespace -s source -d destination
	USAGE
	}

	# Taken from kubectl create -k "github.com/kubernetes-sigs/aws-ebs-csi-driver/deploy/kubernetes/overlays/alpha/?ref=master" --dry-run -oyaml
	# Changes:
	# Change secret info
	# Set hostNetwork for controller
	# Remove liveness probe container
	# Remove healthz ports from controller
