Applies changes to selected instances on the managed instance group. This method can be used to apply new overrides and/or new versions.

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/compute

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: compute1 --scope <scope> instance-group-managers apply-updates-to-instances ...

Required Scalar Arguments

  • <project> (string)
    • Project ID for this request.
  • <zone> (string)
    • The name of the zone where the managed instance group is located. Should conform to RFC1035.
  • <instance-group-manager> (string)
    • The name of the managed instance group, should conform to RFC1035.

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:

InstanceGroupManagersApplyUpdatesRequest:
  all-instances: boolean
  instances: [string]
  minimal-action: string
  most-disruptive-allowed-action: string

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 . all-instances=false
    • Flag to update all instances instead of specified list of “instances”. If the flag is set to true then the instances may not be specified in the request.
  • instances=eirmod
    • The list of URLs of one or more instances for which you want to apply updates. Each URL can be a full URL or a partial URL, such as zones/[ZONE]/instances/[INSTANCE_NAME].
    • Each invocation of this argument appends the given value to the array.
  • minimal-action=dolore
    • The minimal action that you want to perform on each instance during the update: - REPLACE: At minimum, delete the instance and create it again. - RESTART: Stop the instance and start it again. - REFRESH: Do not stop the instance. - NONE: Do not disrupt the instance at all. By default, the minimum action is NONE. If your update requires a more disruptive action than you set with this flag, the necessary action is performed to execute the update.
  • most-disruptive-allowed-action=accusam
    • The most disruptive action that you want to perform on each instance during the update: - REPLACE: Delete the instance and create it again. - RESTART: Stop the instance and start it again. - REFRESH: Do not stop the instance. - NONE: Do not disrupt the instance at all. By default, the most disruptive allowed action is REPLACE. If your update requires a more disruptive action than you set with this flag, the update request will fail.

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 General Properties

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

  • -p $-xgafv=string

    • V1 error format.
  • -p access-token=string

    • OAuth access token.
  • -p alt=string

    • Data format for response.
  • -p callback=string

  • -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

    • Available to use for quota purposes for server-side applications. Can be any arbitrary string assigned to a user, but should not exceed 40 characters.
  • -p upload-type=string

    • Legacy upload protocol for media (e.g. "media", "multipart").
  • -p upload-protocol=string

    • Upload protocol for media (e.g. "raw", "multipart").
  • -p user-ip=string
