murmur patch - Murmur

Performs a partial update on a catalog resource. Only the specified fields are changed — all other fields are preserved.

Synopsis

murmur patch <kind> <name> --set field=value [--file-field field.path=filename ...]

Name	Type	Required	Description
`kind`	string	yes	The catalog resource kind. Run `murmur describe` to list available kinds.
`name`	string	yes	The resource name to update.
`--set`	string	yes (unless `--file-field` is provided)	Set a field to a value. Format: `field=value`. Repeatable. Supports dotted paths for nested fields (e.g. `gcp.project=my-project`).
`--file-field`	string	no	Inject file content at a dotted field path. Format: `field.path=filename`. Repeatable.

At least one --set or --file-field is required.

The --set flag infers the value type automatically:

Input	Inferred type	Example
Integer string	integer	`--set max_vms=100`
`true` / `false`	boolean	`--set paused=true`
Anything else	string	`--set machine_type_ref=murmur-n2-standard-16`

Code	Meaning	What to do
`NOT_FOUND`	No resource with that kind and name exists.	Check the name. Run `murmur get` `<kind>` to list available resources.
`UNAUTHENTICATED`	Identity token is missing or expired.	Run `murmur auth` or check your `murmur.local.yaml` configuration.
`INVALID_ARGUMENT`	The kind is not recognized or a field name or value is invalid.	Run `murmur describe` to check the kind’s schema.
`PERMISSION_DENIED`	The resource is a platform builtin and cannot be modified.	Platform-managed resources are immutable. Create your own resource with a different name.
