NetworkEndpointGroup class

Network endpoint groups (NEGs) are zonal resources that represent collections of IP address and port combinations for GCP resources within a single subnet. Each IP address and port combination is called a network endpoint.

Network endpoint groups can be used as backends in backend services for HTTP(S), TCP proxy, and SSL proxy load balancers. You cannot use NEGs as a backend with internal load balancers. Because NEG backends allow you to specify IP addresses and ports, you can distribute traffic in a granular fashion among applications or containers running within VM instances.

Recreating a network endpoint group that's in use by another resource will give a resourceInUseByAnotherResource error. Use lifecycle.create_before_destroy to avoid this type of error.

Example Usage

Import

NetworkEndpointGroup can be imported using any of these accepted formats:

• projects/{{project}}/zones/{{zone}}/networkEndpointGroups/{{name}}
• {{project}}/{{zone}}/{{name}}
• {{zone}}/{{name}}
• {{name}}

When using the pulumi import command, NetworkEndpointGroup can be imported using one of the formats above. For example:

$ pulumi import gcp:compute/networkEndpointGroup:NetworkEndpointGroup default projects/{{project}}/zones/{{zone}}/networkEndpointGroups/{{name}}
$ pulumi import gcp:compute/networkEndpointGroup:NetworkEndpointGroup default {{project}}/{{zone}}/{{name}}
$ pulumi import gcp:compute/networkEndpointGroup:NetworkEndpointGroup default {{zone}}/{{name}}
$ pulumi import gcp:compute/networkEndpointGroup:NetworkEndpointGroup default {{name}}

Constructors

NetworkEndpointGroup(String name, {NetworkEndpointGroupArgs? args, CustomResourceOptions? options})

Creates a new NetworkEndpointGroup. name The Pulumi resource name. args Arguments used to configure this NetworkEndpointGroup. The set of arguments for NetworkEndpointGroup. options Resource options controlling this resource's behavior.

NetworkEndpointGroup.reference(String urn)

Creates a typed reference to an existing NetworkEndpointGroup resource.

Properties

childResources → Set<Resource>

final, inherited

completionSources ↔ Map<String, IOutputCompletionSource>

late, final, inherited

defaultPort ↔ Output<int?>

The default port used if the port number is not specified in the network endpoint.

late, final

deletionPolicy ↔ Output<String>

Whether Terraform will be prevented from destroying the resource. Defaults to DELETE. When a 'terraform destroy' or 'pulumi up' would delete the resource, the command will fail if this field is set to "PREVENT" in Terraform state. When set to "ABANDON", the command will remove the resource from Terraform management without updating or deleting the resource in the API. When set to "DELETE", deleting the resource is allowed.

late, final

description ↔ Output<String?>

An optional description of this resource. Provide this property when you create the resource.

late, final

generatedId ↔ Output<int>

The uniquely generated identifier for the resource. This identifier is defined by the server.

late, final

hashCode → int

The hash code for this object.

no setter, inherited

id ↔ Output<String>

getter/setter pair, inherited

isCustom → bool

Returns whether this resource is provider-managed.

no setter, inherited

isProtected → bool

Returns whether this resource is protected from deletion.

no setter, inherited

isRemote → bool

Whether this resource is registered as remote.

no setter, inherited

isResourceReference → bool

Whether this instance represents a resource value returned over RPC.

final, inherited

name ↔ Output<String>

Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression a-z? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

late, final

network ↔ Output<String>

The network to which all network endpoints in the NEG belong. Uses "default" project network if unspecified.

late, final

networkEndpointType ↔ Output<String?>

Type of network endpoints in this network endpoint group. NON_GCP_PRIVATE_IP_PORT is used for hybrid connectivity network endpoint groups (see https://cloud.google.com/load-balancing/docs/hybrid). Note that NON_GCP_PRIVATE_IP_PORT can only be used with Backend Services that 1) have the following load balancing schemes: EXTERNAL, EXTERNAL_MANAGED, INTERNAL_MANAGED, and INTERNAL_SELF_MANAGED and 2) support the RATE or CONNECTION balancing modes. Possible values include: GCE_VM_IP, GCE_VM_IP_PORT, NON_GCP_PRIVATE_IP_PORT, INTERNET_IP_PORT, INTERNET_FQDN_PORT, SERVERLESS, and PRIVATE_SERVICE_CONNECT. Default value is GCE_VM_IP_PORT. Possible values are: GCE_VM_IP, GCE_VM_IP_PORT, NON_GCP_PRIVATE_IP_PORT, INTERNET_IP_PORT, INTERNET_FQDN_PORT, SERVERLESS, PRIVATE_SERVICE_CONNECT, GCE_VM_IP_DEDICATED_BACKEND.

late, final

project ↔ Output<String>

The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

late, final

resourceTransforms → List<ResourceTransform>

Inherited/explicit async transforms.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

selfLink ↔ Output<String>

The URI of the created resource.

late, final

size ↔ Output<int>

Number of network endpoints in the network endpoint group.

late, final

subnetwork ↔ Output<String?>

Optional subnetwork to which all network endpoints in the NEG belong.

late, final

transformations → List<ResourceTransformation>

Inherited/explicit legacy transformations.

no setter, inherited

urn ↔ Output<String>

late, final, inherited

zone ↔ Output<String>

Zone where the network endpoint group is located.

late, final
