Updates an IAM policy for the specified object.

Scopes

You will need authorization for at least one of the following scopes to make a valid call:

  • https://www.googleapis.com/auth/cloud-platform
  • https://www.googleapis.com/auth/devstorage.full_control
  • https://www.googleapis.com/auth/devstorage.read_write

If unset, the scope for this method defaults to https://www.googleapis.com/auth/cloud-platform. You can set the scope for this method like this: storage1 --scope <scope> objects set-iam-policy ...

Required Scalar Arguments

  • <bucket> (string)
    • Name of the bucket in which the object resides.
  • <object> (string)
    • Name of the object. For information about how to URL encode object names to be path safe, see Encoding URI Path Parts.

Required Request Value

The request value is a data-structure with various fields. Each field may be a simple scalar or another data-structure. In the latter case it is advised to set the field-cursor to the data-structure's field to specify values more concisely.

For example, a structure like this:

Policy:
  etag: string
  kind: string
  resource-id: string
  version: integer

can be set completely with the following arguments which are assumed to be executed in the given order. Note how the cursor position is adjusted to the respective structures, allowing simple field names to be used most of the time.

  • -r . etag=amet.
    • HTTP 1.1 Entity tag for the policy.
  • kind=est
    • The kind of item this is. For policies, this is always storage#policy. This field is ignored on input.
  • resource-id=gubergren
    • The ID of the resource to which this policy belongs. Will be of the form projects//buckets/bucket for buckets, projects//buckets/bucket/objects/object for objects, and projects//buckets/bucket/managedFolders/managedFolder. A specific generation may be specified by appending #generationNumber to the end of the object name, e.g. projects//buckets/my-bucket/objects/data.txt#17. The current generation can be denoted with #0. This field is ignored on input.
  • version=26
    • The IAM policy format version.

About Cursors

The cursor position is key to comfortably set complex nested structures. The following rules apply:

  • The cursor position is always set relative to the current one, unless the field name starts with the . character. Fields can be nested such as in -r f.s.o .
  • The cursor position is set relative to the top-level structure if it starts with ., e.g. -r .s.s
  • You can also set nested fields without setting the cursor explicitly. For example, to set a value relative to the current cursor position, you would specify -r struct.sub_struct=bar.
  • You can move the cursor one level up by using ... Each additional . moves it up one additional level. E.g. ... would go three levels up.

Optional Output Flags

The method's return value a JSON encoded structure, which will be written to standard output by default.

  • -o out
    • out specifies the destination to which to write the server's result to. It will be a JSON-encoded structure. The destination may be - to indicate standard output, or a filepath that is to contain the received bytes. If unset, it defaults to standard output.

Optional Method Properties

You may set the following properties to further configure the call. Please note that -p is followed by one or more key-value-pairs, and is called like this -p k1=v1 k2=v2 even though the listing below repeats the -p for completeness.

  • -p generation=string

    • If present, selects a specific revision of this object (as opposed to the latest version, the default).

  • -p user-project=string

    • The project to be billed for this request. Required for Requester Pays buckets.

Optional General Properties

The following properties can configure any call, and are not specific to this method.

  • -p alt=string

    • Data format for the response.

  • -p fields=string

    • Selector specifying which fields to include in a partial response.

  • -p key=string

    • API key. Your API key identifies your project and provides you with API access, quota, and reports. Required unless you provide an OAuth 2.0 token.

  • -p oauth-token=string

    • OAuth 2.0 token for the current user.

  • -p pretty-print=boolean

    • Returns response with indentations and line breaks.

  • -p quota-user=string

    • An opaque string that represents a user for quota purposes. Must not exceed 40 characters.

  • -p upload-type=string

    • Upload protocol for media (e.g. "media", "multipart", "resumable").

  • -p user-ip=string

    • Deprecated. Please use quotaUser instead.
