Minio

src

Minio is a high performance distributed object storage server, designed for large-scale private cloud infrastructure. Minio is a self-hosted alternative to AWS S3.

We will use it for fun as a way to store files and images for our local cloud services.

But we will also use it for our Grafana instance services to store logs and traces.

Setup​

Lets start by creating a new directory for our minio instance.

mkdir -p ~/local-cloud/minio
cd ~/local-cloud/minio

Now we can create a docker-compose.yml file to start our minio instance.

version: '3.8'

networks:
  proxy:
    external: true

volumes:
  buckets:

services:
  minio:
    container_name: minio 
    hostname: minio
    image: minio/minio:latest
    restart: unless-stopped
    entrypoint: 
      - sh 
      - -euc 
      - mkdir -p /data/tempo && mkdir -p /data/loki-data && mkdir -p /data/loki-ruler && minio server /data --console-address ':9001'
    networks:
      - proxy
    environment:
      - MINIO_ROOT_USER=automation
      - MINIO_ROOT_PASSWORD=supersecret
    volumes:
      - buckets:/data
    ports:
      - 9001:9001
      - 9000:9000
    labels:
    - "traefik.enable=true"
    - "traefik.http.routers.minio.rule=Host(`minio.localhost`) || Host(`minio.dev.localhost`)"
    - "traefik.http.routers.minio.entrypoints=web,websecure"
    - "traefik.http.routers.minio.tls=true"
    - "traefik.http.routers.minio.service=minio@docker"
    - "traefik.http.services.minio.loadBalancer.server.port=9001"
    - "traefik.http.services.minio.loadBalancer.server.scheme=http"
    
    - "traefik.http.routers.s3.rule=Host(`s3.localhost`) || Host(`s3.dev.localhost`)"
    - "traefik.http.routers.s3.entrypoints=web,websecure"
    - "traefik.http.routers.s3.tls=true"
    - "traefik.http.routers.s3.service=s3@docker"
    - "traefik.http.services.s3.loadBalancer.server.port=9000"
    - "traefik.http.services.s3.loadBalancer.server.scheme=http"
  • Volumes - We are creating a volume for our minio buckets to persist data.
  • Entrypoint - We are creating directories for our logs and traces and starting minio server on port 9001. These directories will show up as buckets in minio UI.
  • Ports - We are exposing minio on port 9000 and 9001. 9000 is the default port for minio and 9001 is the console port.
  • Labels - We are using traefik to route traffic to minio. We are exposing minio ui on minio.localhost and minio api s3.localhost.

Root User and Pass​

We are setting the root user and password for minio to automation and supersecret. You can change this to whatever you like in the variables.

Start Minio​

Now we can start our minio instance.

docker compose up -d

You should be able to access Minio UI

Minio Console

Login with root user

src

Then you will get taken to the dashboard and see the buckets we generated at startup.

Next Steps​

Now that we have Minio setup we can use it to store files and images for our local cloud services.
