kube-microcosm's Introduction

New example here -> https://github.com/cloud-native-skunkworks/gitops-kubernetes-bootstrap

kube-microcosm

A cluster that represents how a small start-up might be successful using a single Kubernetes cluster.

This is an opinionated illustration of a Kubernetes cluster and out-of-the-box applications.

Requirements

  • step
  • helm
  • kubectl

Installation

  1. Ensure an existing Kubernetes cluster config is active. I like using civo.
civo kubernetes create interesting-times-gang -n3 --wait --remove-applications=traefik -s g3.k3s.large tycho --region NYC1
civo kubernetes config interesting-times-gang -s
  1. Run the following ( With your variables):
// Example Slack webhook within a Slack App
SLACK_FALCO_WEBHOOK_URL="<YOUR SLACK WEBHOOK>" \
make install

or without...

make install

kube-microcosm's Issues

prom-config.yaml is missing

The make install fails indicating that the file resource/prometheus/prom-config.yaml is missing.

The build itself went well after changing:

d=date -v+8760H +"%Y-%m-%dT%H:%M:%SZ"

to

d=date -d '+8760 hour' +"%Y-%m-%dT%H:%M:%SZ"

for Ubuntu
