Storage
Object storage organized into buckets that hold objects (files). Policies govern access to a bucket, and each object has a public/private visibility.
What it is
Object storage organized into buckets that hold objects (files). Policies govern access to a bucket, and each object has a public/private visibility.
How it relates
- Belongs to a project.
- Functions read and write objects at runtime.
- Policies control access; they can be managed with the CLI or declared in
the declarative config (an omitted
policieskey leaves a bucket's policies untouched).
