I have set up an AWS Elastic Load Balancer and AutoScaling Group of 30 instances. こんにちは、AWSで1台のEC2に対してロードバランサを設定してアクセスしたいと思っています。 理由としてはロードバランサにAWSで発行される証明書を設定するためです。 まずテストとして、ロードバランサ無しで80番ポートでEC2まで届くものを作成しようと思い以下のような構成にしました To ensure that the load balancer can scale properly, verify that each subnet for the load balancer has a CIDR block with at least a /27 bitmask (for example, 10.0.0.0/27) and has at least 8 free IP addresses. delete - (Default 10m) How long to retry on DependencyViolation errors during security group deletion from lingering ENIs left by certain AWS services such as Elastic Load Balancing. AWSの基本サービスであるEC2のセキュリティグループの設定を変更してみましょう。ここでは外部からPingが通る設定と、Webサーバの機能を試してみます。EC2を再起動することなく設定が反映されます。 1. aws_security_group provides the following Timeouts configuration options: create - (Default 10m) How long to wait for a security group to be created. Run describe-security-groups command (OSX/Linux/UNIX) using each security group ID exposed in the previous step to determine if the security group is invalid: Your load balancer uses these IP addresses to establish connections with the backend instances; for more information, see VPCs and Subnets.

Kubernetes and AWS: Set LoadBalancer to use predefined Security Group. This resource can prove useful when a module accepts a Security Group id as an input variable and needs to, for example, determine the id of the VPC that the security group belongs to.
