Setting up Minio

This is a Docker Compose configuration example on deploying MinIO object storage.

MinIO is a high performance object storage and is API compatible with Amazon S3 cloud storage service. It's been a while since last time I setup Minio and boy has it improved. One of the changes is that it now has two endpoints, one for the API and one for the console (WebUI). If the API receives a request from a browser it will redirect the request to the console URL. That is why we need to create two routes in Traefik.

Docker Compose

Below is as docker compose that deploys Minio with my usual Traefik setup.

  • Create two random strings, with below command, for the MINIO_ROOT_USER and MINIO_ROOT_PASSWORD environment variables.
  • Change the minio.example.org and minio-console.example.org domain names.
  • Set the minio data folder.
openssl rand -base64 32
