devops-stack-module-minio

A DevOps Stack module to deploy MinIO.

The MinIO chart used by this module is shipped in this repository as well, in order to avoid any unwanted behaviors caused by unsupported versions.

Usage

This module can be declared by adding the following block on your Terraform configuration:

module "minio" {
  source = "git::https://github.com/camptocamp/devops-stack-module-minio.git?ref=<RELEASE>"

  cluster_name     = local.cluster_name
  base_domain      = local.base_domain
  cluster_issuer   = local.cluster_issuer
  argocd_namespace = module.argocd_bootstrap.argocd_namespace

  enable_service_monitor = false # Needs to be false for the first deployment

  config_minio = local.minio_config

  oidc = module.oidc.oidc

  dependency_ids = {
    argocd = module.argocd_bootstrap.id
  }
}

The config_minio variable is where you create the necessary policies, users and buckets. In this example, we defined them inside a Terraform local variable:

resource "random_password" "loki_secretkey" {
  length  = 32
  special = false
}
resource "random_password" "thanos_secretkey" {
  length  = 32
  special = false
}

locals {
  minio_config = {
    policies = [
      {
        name = "loki-policy"
        statements = [
          {
            resources = ["arn:aws:s3:::loki-bucket"]
            actions   = ["s3:CreateBucket", "s3:DeleteBucket", "s3:GetBucketLocation", "s3:ListBucket", "s3:ListBucketMultipartUploads"]
          },
          {
            resources = ["arn:aws:s3:::loki-bucket/*"]
            actions   = ["s3:GetObject", "s3:PutObject", "s3:DeleteObject"]
          }
        ]
      },
      {
        name = "thanos-policy"
        statements = [
          {
            resources = ["arn:aws:s3:::thanos-bucket"]
            actions   = ["s3:CreateBucket", "s3:DeleteBucket", "s3:GetBucketLocation", "s3:ListBucket", "s3:ListBucketMultipartUploads"]
          },
          {
            resources = ["arn:aws:s3:::thanos-bucket/*"]
            actions   = ["s3:GetObject", "s3:PutObject", "s3:DeleteObject"]
          }
        ]
      }
    ],
    users = [
      {
        accessKey = "loki-user"
        secretKey = random_password.loki_secretkey.result
        policy    = "loki-policy"
      },
      {
        accessKey = "thanos-user"
        secretKey = random_password.thanos_secretkey.result
        policy    = "thanos-policy"
      }
    ],
    buckets = [
      {
        name = "loki-bucket"
      },
      {
        name = "thanos-bucket"
      }
    ]
  }
}
Check the KinD deployment tutorial and example to get a better idea of how these buckets are configured and used.

WebUI Login

This module is configured to used OIDC out-of-the-box, as long as the proper scope is passed. You can check the official documentation page to get more information about the way this is configured.

However, there is no way to configure the OIDC login as default on the login page, so take note that in order to use the OIDC login you need to click on Other Authentication Methods then Login using SSO ()_, as shown in the screenshot below.
