listgroupmembers

Documentation

Overview

Package listgroupmembers extract all members from a group in GCI directory using the Admin SDK API

Triggered by

PubSub messages from the GCI groups topic.

Instances

Only one.

Output

PubSub messages to a dedicated topic formated like Cloud Asset Inventory feed messages.

Cardinality

One-many: one group may have many members.

There is no limit in GCI on the number of members in a group.

Automatic retrying

Yes.

Domain Wide Delegation

Yes. The service account used to run this cloud function must have domain wide delegation and the following Oauth scopes:

- https://www.googleapis.com/auth/admin.directory.group.member.readonly

Key rotation strategy

Same as listgroups microservice.

Implementation example

package p
import (
    "context"

    "github.com/BrunoReboul/ram/services/listgroupmembers"
    "github.com/BrunoReboul/ram/utilities/ram"
)
var global listgroupmembers.Global
var ctx = context.Background()

// EntryPoint is the function to be executed for each cloud function occurence
func EntryPoint(ctxEvent context.Context, PubSubMessage gps.PubSubMessage) error {
    return listgroupmembers.EntryPoint(ctxEvent, PubSubMessage, &global)
}

func init() {
    listgroupmembers.Initialize(ctx, &global)
}

Functions

func EntryPoint

func EntryPoint(ctxEvent context.Context, PubSubMessage gps.PubSubMessage, global *Global) error

EntryPoint is the function to be executed for each cloud function occurence

func Initialize

func Initialize(ctx context.Context, global *Global)

Initialize is to be executed in the init() function of the cloud function to optimize the cold start

Types

type Global

type Global struct {
	// contains filtered or unexported fields
}

Global structure for global variables to optimize the cloud function performances

type InstanceDeployment

type InstanceDeployment struct {
	DumpTimestamp time.Time `yaml:"dumpTimestamp"`
	Core          *deploy.Core
	Settings      struct {
		Service struct {
			GSU                     gsu.Parameters
			IAM                     iamgt.Parameters
			GCB                     gcb.Parameters
			GCF                     gcf.Parameters
			KeyJSONFileName         string `yaml:"keyJSONFileName"`
			LogEventEveryXPubSubMsg uint64 `yaml:"logEventEveryXPubSubMsg"`
			MaxResultsPerPage       int64  `yaml:"maxResultsPerPage"`
		}
		Instance struct {
			GCF gcf.Event
			GCI struct {
				SuperAdminEmail string `yaml:"superAdminEmail"`
			}
		}
	}
}

InstanceDeployment settings and artifacts structure

func NewInstanceDeployment

func NewInstanceDeployment() *InstanceDeployment

NewInstanceDeployment create deployment structure with default settings set

func (*InstanceDeployment) Deploy

func (instanceDeployment *InstanceDeployment) Deploy() (err error)

Deploy a service instance

func (*InstanceDeployment) ReadValidate

func (instanceDeployment *InstanceDeployment) ReadValidate() (err error)

ReadValidate reads and validates service and instance settings

func (*InstanceDeployment) Situate

func (instanceDeployment *InstanceDeployment) Situate() (err error)

Situate complement settings taking in account the situation for service and instance settings
