This building block consumes 6 input parameters
Name | Format | Description |
---|---|---|
project Required |
STRING |
Project ID for this request |
zone Required |
STRING |
The name of the zone where the managed instance group is located |
filter |
STRING |
A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either =, !=, >, or <. For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance. You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake"). By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example, (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) |
maxResults |
INTEGER |
The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500) |
orderBy |
STRING |
Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by name or creationTimestamp desc is supported |
pageToken |
STRING |
Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results |

Name | Format | Description |
---|---|---|
id |
STRING |
[Output Only] Unique identifier for the resource; defined by the server |
items[] |
OBJECT |
Represents a Managed Instance Group resource. An instance group is a collection of VM instances that you can manage as a single entity. For more information, read Instance groups. For zonal Managed Instance Group, use the instanceGroupManagers resource. For regional Managed Instance Group, use the regionInstanceGroupManagers resource. (== resource_for beta.instanceGroupManagers ==) (== resource_for v1.instanceGroupManagers ==) (== resource_for beta.regionInstanceGroupManagers ==) (== resource_for v1.regionInstanceGroupManagers ==) |

items[].autoHealingPolicies[].initialDelaySec |
INTEGER |
The number of seconds that the managed instance group waits before it applies autohealing policies to new instances or recently recreated instances. This initial delay allows instances to initialize and run their startup scripts before the instance group determines that they are UNHEALTHY. This prevents the managed instance group from recreating its instances prematurely. This value must be from range [0, 3600] |
items[].baseInstanceName |
STRING |
The base instance name to use for instances in this group. The value must be 1-58 characters long. Instances are named by appending a hyphen and a random four-character string to the base instance name. The base instance name must comply with RFC1035 |

items[].targetPools[] |
STRING |

However, if the Updater determines that the minimal action you specify is not enough to perform the update, it might perform a more disruptive action |
items[].updatePolicy.type |
ENUMERATION |
The type of update process. You can specify either PROACTIVE so that the instance group manager proactively executes actions in order to bring instances to their target versions or OPPORTUNISTIC so that no action is proactively executed but the update will be performed as part of other actions (for example, resizes or recreateInstances calls) |

[Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding) |
