SeaweedFS (S3-compatible Object Store)

Description

SeaweedFS is a fast, distributed object store with an Apache-2.0 license. This showcase deploys a single-pod, all-in-one SeaweedFS instance that exposes an S3-compatible endpoint inside the cluster. It serves as a lightweight, license-friendly alternative to MinIO for demos that need an object store — for example as the backup target for the Velero showcase.

Installation

cd examples/seaweedfs
bash setup.sh

Optionally pass an additional bucket name to create:

bash setup.sh my-extra-bucket

The setup script:

• Creates the seaweedfs namespace
• Deploys SeaweedFS as a StatefulSet running weed server -filer -s3 (master, volume, filer and S3 gateway in one pod)
• Provisions a 10 GiB PVC for object data
• Creates a default bucket called demo

Endpoint and credentials

Property	Value
In-cluster S3 endpoint	http://seaweedfs-s3.seaweedfs.svc.cluster.local:8333
Filer HTTP API	http://seaweedfs.seaweedfs.svc.cluster.local:8888
Master HTTP API	http://seaweedfs.seaweedfs.svc.cluster.local:9333
Access key	seaweedadmin
Secret key	seaweedadminsecret

The credentials are static and committed to this repo. They are intended for local Lab use only — never reuse them in any environment that is reachable beyond your machine.

Smoke test with the AWS CLI

From inside the cluster (or via kubectl run with the amazon/aws-cli image):

kubectl run aws-cli --rm -it --restart=Never \
  --image=amazon/aws-cli:latest \
  --env=AWS_ACCESS_KEY_ID=seaweedadmin \
  --env=AWS_SECRET_ACCESS_KEY=seaweedadminsecret \
  -- s3 --endpoint-url http://seaweedfs-s3.seaweedfs:8333 ls

Managing buckets via weed shell

kubectl -n seaweedfs exec -it seaweedfs-0 -- \
  sh -c "echo 's3.bucket.list' | weed shell -master localhost:9333 -filer localhost:8888"

Used by

• Velero Backup & Restore — uses SeaweedFS as the backup storage location.

Cleanup

kubectl delete namespace seaweedfs
