summary: "Send modifications to the cluster layout"
description: |
Send modifications to the cluster layout. These modifications will be included in the staged role changes, visible in subsequent calls of `GET /layout`. Once the set of staged changes is satisfactory, the user may call `POST /layout/apply` to apply the changed changes, or `POST /layout/revert` to clear all of the staged changes in the layout.
Note that setting the capacity to `null` will configure the node as a gateway.
Setting the capacity to `null` will configure the node as a gateway.
Otherwise, capacity must be now set in bytes (before Garage 0.9 it was arbitrary weights).
For example to declare 100GB, you must set `capacity: 100000000000`.
Garage uses internally the International System of Units (SI), it assumes that 1kB = 1000 bytes, and displays storage as kB, MB, GB (and not KiB, MiB, GiB that assume 1KiB = 1024 bytes).

To add a new node to the layout or to change the configuration of an existing node, simply set the values you want (`zone`, `capacity`, and `tags`).

Similarly to the CLI, the body must include the version of the new layout that will be created, which MUST be 1 + the value of the currently existing layout in the cluster.
