amazon-web-services - 如何添加规则以允许AWS EKS上的nodePort在某些端口范围上的流量？

Question

我在nodePort上公开的服务似乎不允许流量通过它。

那么，如何添加规则以允许CLI上的该端口范围的流量不在控制台上？

Answer 1

EC2安全组

屏幕上有一个security group。

查看有关安全组的更多信息:

EC2 Security Groups

Creating a Security Group

CLI的 AWS Security groups
至于使用 CLI的 AWS Security groups，请参见此文章: Creating, Configuring, and Deleting Security Groups for Amazon EC2 - AWS Command Line Interface

$ aws ec2 create-security-group --group-name my-sg --description "My security group" --vpc-id vpc-1a2b3c4d
{
    "GroupId": "sg-903004f8"
}

$ aws ec2 authorize-security-group-ingress --group-id sg-903004f8 --protocol tcp --port 3389 --cidr 203.0.113.0/24

The following command adds another rule to enable SSH to instances in the same security group.

$ aws ec2 authorize-security-group-ingress --group-id sg-903004f8 --protocol tcp --port 22 --cidr 203.0.113.0/24

To view the changes to the security group, run the describe-security-groups command.

$ aws ec2 describe-security-groups --group-ids `sg-903004f8`

O / P为:

{
    "SecurityGroups": [
        {
            "IpPermissionsEgress": [
                {
                    "IpProtocol": "-1",
                    "IpRanges": [
                        {
                            "CidrIp": "0.0.0.0/0"
                        }
                    ],
                    "UserIdGroupPairs": []
                }
            ],
            "Description": "My security group"
            "IpPermissions": [
                {

                        }
                    ]
                    "UserIdGroupPairs": [],
                    "FromPort": 22
                }
            ],
            "GroupName": "my-sg",
            "OwnerId": "123456789012",
            "GroupId": "sg-903004f8"
        }
    ]
}

附言 awless.io-适用于AWS的强大CLI

还有一些过时但仍很方便的 CLI工具:
