SecurityGroupRule class

Provides a security group rule resource. Represents a single ingress or egress group rule, which can be added to external Security Groups.

> NOTE: Avoid using the aws.ec2.SecurityGroupRule resource, as it struggles with managing multiple CIDR blocks, and, due to the historical lack of unique IDs, tags and descriptions. To avoid these problems, use the current best practice of the aws.vpc.SecurityGroupEgressRule and aws.vpc.SecurityGroupIngressRule resources with one CIDR block per rule.

> WARNING: You should not use the aws.ec2.SecurityGroupRule resource in conjunction with aws.vpc.SecurityGroupEgressRule and aws.vpc.SecurityGroupIngressRule resources or with an aws.ec2.SecurityGroup resource that has in-line rules. Doing so may cause rule conflicts, perpetual differences, and result in rules being overwritten.

> NOTE: Setting protocol = "all" or protocol = -1 with fromPort and toPort will result in the EC2 API creating a security group rule with all ports open. This API behavior cannot be controlled by this provider and may generate warnings in the future.

> NOTE: Referencing Security Groups across VPC peering has certain restrictions. More information is available in the VPC Peering User Guide.

Example Usage

Basic usage

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

const example = new aws.ec2.SecurityGroupRule("example", {

Usage With Prefix List IDs

Prefix Lists are either managed by AWS internally, or created by the customer using a Managed Prefix List resource. Prefix Lists provided by AWS are associated with a prefix list name, or service name, that is linked to a specific region.

Prefix list IDs are exported on VPC Endpoints, so you can use this format:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// ...
const myEndpoint = new aws.ec2.VpcEndpoint("my_endpoint", {});
const allowAll = new aws.ec2.SecurityGroupRule("allow_all", {
    type: "egress",
    toPort: 0,
    protocol: "-1",
    prefixListIds: [myEndpoint.prefixListId],
    fromPort: 0,
    securityGroupId: "sg-123456",
});

import pulumi
import pulumi_aws as aws

# ...
my_endpoint = aws.ec2.VpcEndpoint("my_endpoint")
allow_all = aws.ec2.SecurityGroupRule("allow_all",
    type="egress",
    to_port=0,
    protocol="-1",
    prefix_list_ids=[my_endpoint.prefix_list_id],
    from_port=0,
    security_group_id="sg-123456")

        PrefixListIds = new[]
        {

Import

Import a rule with various IPv4 and IPv6 source CIDR blocks:

Import a rule, applicable to all ports, with a protocol other than TCP/UDP/ICMP/ICMPV6/ALL, e.g., Multicast Transport Protocol (MTP), using the IANA protocol number. For example: 92.

Import a default any/any egress rule to 0.0.0.0/0:

Import an egress rule with a prefix list ID destination:

Import a rule applicable to all protocols and ports with a security group source:

Import a rule that has itself and an IPv6 CIDR block as sources:

Using pulumi import to import Security Group Rules using the securityGroupId, type, protocol, fromPort, toPort, and source(s)/destination(s) (such as a cidrBlock) separated by underscores (_). All parts are required. For example:

NOTE: Not all rule permissions (e.g., not all of a rule's CIDR blocks) need to be imported for this provider to manage rule permissions. However, importing some of a rule's permissions but not others, and then making changes to the rule will result in the creation of an additional rule to capture the updated permissions. Rule permissions that were not imported are left intact in the original rule.

Import an ingress rule in security group sg-6e616f6d69 for TCP port 8000 with an IPv4 destination CIDR of 10.0.3.0/24:

$ pulumi import aws:ec2/securityGroupRule:SecurityGroupRule ingress sg-6e616f6d69_ingress_tcp_8000_8000_10.0.3.0/24
