Storage

Bytes go to the blob backend; the catalog is Cloud metadata. → Storage concept

Storage → Create bucket, then choose a file and Upload (the key defaults to the file name). Rows show state, size, content_type, etag; Download and Delete… per object.

hcloud storage buckets create prj_… assets
hcloud storage put prj_… assets ./hello.txt docs/hello.txt --content-type text/plain
hcloud storage ls  prj_… assets
hcloud storage get prj_… assets docs/hello.txt ./hello.copy.txt
hcloud storage rm  prj_… assets docs/hello.txt

await cloud.storage.buckets.create(project.id, "assets");
const obj = await cloud.storage.upload(project.id, { bucket: "assets", key: "docs/hello.txt", body: "hello", contentType: "text/plain" });
const { objects } = await cloud.storage.list(project.id, "assets");
const bytes = await cloud.storage.download(project.id, { bucket: "assets", key: "docs/hello.txt" });
await cloud.storage.remove(project.id, { bucket: "assets", key: "docs/hello.txt" });
// With a project key instead of the session:
const data = cloud.data(project.id, { key });
await data.storage.upload({ bucket: "assets", key: "app.json", body: JSON.stringify({ ok: true }), contentType: "application/json" });

Objects are capped at 32 MiB by default (413 payload_too_large beyond). Bucket names: 3–63 chars of a-z 0-9 -. Only the session may create buckets; a project key may do everything else.
