Review the following settings in your configuration: Public and Elastic IP addresses. Verify that your instance has an associated public IP address or Elastic IP address using Determining Your Public, Private, and Elastic IP Addresses.Be sure to use this IP address when connecting to the instance. i would like to find the public IP address of my EC2 instance from within the server itself.I know it is possible using ec2-describe-instances. But i want to do it assuming ec2-api-tools are not # Basic provisioning example-ec2: key_name: mykey instance_type: t2.micro image: ami-123456 wait: yes group: webserver count: 3 vpc_subnet_id: subnet-29e63245 assign_public_ip: yes # Advanced example with tagging and CloudWatch-ec2: key_name: mykey group: databases instance_type: t2.micro image: ami-123456 wait: yes wait_timeout: 500 count: 5 Most EC2 instances are not intended to be publicly accessible, being assigned private IP addresses valid only within a specific virtual private cloud. However, sometimes an EC2 instance needs to be accessible to the public, like a web front end that needs to be accessible via the Internet. AWS makes this possible through the use of elastic IP addresses, and here Brien Posey shows you how to do But for our public subnet, we need to auto assign a public IP address. otherwise, we won't be able to access the public internet after we provisioned any EC2 inside this public subnet. A full list of EC2 instance types can be found here. As you have probably noticed this instance has been associated with the public subnet that was specified earlier, subnet_id = "${aws_subnet.public.id}". The associate_public_ip_address = "true" property associates a public elastic IP address with the instance. This means that the instance

The private DNS name of the specified instance. For example: ip-10-24-34-.ec2.internal. PrivateIp. The private IP address of the specified instance. For example: 10.24.34.. PublicDnsName. The public DNS name of the specified instance. For example: ec2-107-20-50-45.compute-1.amazonaws.com. PublicIp. The public IP address of the specified instance. For example, if you're connecting to a server, consider allowing traffic on HTTP port 80 and HTTPS port 443, using the destination IP address 0.0.0.0/0. For more information, see Amazon EC2 security groups for Linux instances or Amazon EC2 security groups for Windows instances.
amazon ec2 - Can't access AWS EC2 instance via public IP
For EC2-VPC, this is only available if you've enabled DNS hostnames for your VPC public_ip - The public IP address assigned to the instance, if applicable. NOTE: If you are using an aws_eip with your instance, you should refer to the EIP's address directly and not use public_ip, as this field will change after the EIP is attached. An Elastic IP address ensures that the IP address of your Amazon EC2 instance will never change. A registered domain name. You can use Amazon Route 53 as your domain registrar, or you can use a different registrar. If you didn't associate an Elastic IP with the instance, get the value of IPv4 Public IP. 詳細ペインで、[IPv4 Public IP] フィールドからパブリック IP アドレスを、[Public DNS (IPv4)] フィールドから外部 DNS ホスト名を取得します。 1 つ以上の Elastic IP アドレスがインスタンスに関連付けられている場合は、Elastic IP アドレスを [ Elastic IPs ] フィールド Select the EC2 instance without a public DNS. Then Actions - Associate Address. The Address field, select the new elastic IP address. The Associate to private IP address field, select the private IP address with no public DNS. Click Associate Address. Your EC2 instance should now have a public DNS. Assign, reassign, remove an Elastic IP address - An instance (in EC2-Classic) can only have one public IP address at any given time. An instance (in a VPC) can have multiple public ip addresses. When an instance is assigned an Elastic IP, the EIP becomes its new public IP address and its previous public IP address (if one has already been Then associate these public subnets to the internet-facing load balancer. Public subnet. If a subnet's default traffic is routed to an internet gateway, the subnet is known as a public subnet. For example, an instance launched in this subnet is publicly accessible if it has an Elastic IP address or a public IP address associated with it.
