M3s - Apache Mesos Kubernetes Framework

Introduction

M3s is a Golang based Apache Mesos Framework to run and deploy Kubernetes through K3s from Rancher.

Requirements

Apache Mesos min 1.6.0
Mesos with SSL and Authentication is optional
Persistent Storage to store Kubernetes data

How To use

Before we can run the following M3s example, we have to creat a docker network.


docker network create --subnet 10.32.0.0/24 mini

Afte that, we can create a docker-compose file to run the services we need.


version: '3'
services:
  redis:
    image: redis
  m3s:
    image: avhost/mesos-m3s:master
    depends: redis
    environment:
    - LOGLEVEL="debug"
    - DOMAIN=.mini
    - DOCKER_CNI=mini
    - K3S_AGENT_COUNT=1
    - REDIS_SERVER=redis.mini:6379
    - K3S_TOKEN=l9WpVPQQw2sfNQRbxJDXjZx61wMpXDaB
    - VOLUME_K3S_SERVER="local_k3sserver"
    - AUTH_USERNAME=user
    - AUTH_PASSWORD=password
    ports:
      - 10000

After that, we can execute docker-compose in the same directory where we have created our compose file.


docker compose up

If Kubernetes is running inside of M3s, we can export the kubeconfig file with our mesos-cli or with a simple API call.


curl -k -X GET http://127.0.0.1:10000/api/m3s/v0/server/config

No we can use kubectl and all other Kubernetes specified commands.


kubectl get nodes
NAME                     STATUS   ROLES                  AGE   VERSION
m3sserver.mini           Ready    control-plane,master   18h   v1.24.4+k3s1
m3sagent.mini-8aee249f   Ready    <none>                 17h   v1.24.4+k3s1

Get the token and start the proxy.



kubectl -n kubernetes-dashboard create token admin-user
kubectl proxy

And then open the browser:

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/
