S3 buckets
S3-compatible object storage for your services.
An S3 bucket is a service in a project with its own access keys. Create one with a name: 3–63 lowercase letters, digits and hyphens. Names are unique across the whole platform and cannot change later.
Access
The bucket's Overview shows its endpoint, bucket name, region, access key ID and, on request, the secret access key. The keys reach only this bucket.
A Kubernetes Secret in the project holds the keys under the names AWS SDKs
read: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_ENDPOINT_URL and
AWS_REGION, plus S3_BUCKET with the bucket name. The endpoint is reachable from services in this cluster only.
Regenerate keys
Settings → Regenerate keys replaces both keys, and the current ones stop working immediately. Services that read the keys from the Secret keep the old ones until they restart, so restart them. Tools configured by hand need the new keys too.
Files
The Explore tab browses the bucket's files, creates folders and uploads files.
Deleting a bucket deletes every object in it and its access keys.
Object storage
Every bucket, PostgreSQL backup and static site file is stored in one RustFS instance on a Longhorn volume. While it restarts, buckets and backups are unavailable, and new static site instances cannot start.
