minio-ha

MinIO HA

MinIO is a popular distributed object storage system that allows organizations to deploy highly available and scalable storage infrastructure. In order to achieve high availability (HA) for MinIO, a cluster of multiple MinIO nodes must be deployed backed by their own set of PVCs.

Requirements

• Kubernetes >= 1.23.0
• Kustomize >= v3.5.3
• prometheus-operator from KFD monitoring module

Prometheus Operator is necessary since we configure a ServiceMonitor to make some metrics available from minio on prometheus

Image repository and tag

• MinIO image: minio/minio
• MinIO repo: MinIO on GitHub

Configuration

MinIO HA is deployed in the following configuration:

• Three Pod MinIO statefulset with 2 PVCs per Pod
• Custom init Job to initialize buckets (loki and errors) and default retention (7 days on errors bucket)

Deployment

You can deploy minio-ha by running the following command in the root of the project:

kustomize build | kubectl apply -f -
