Use one AWS Elastic IP for several instances

阅读更多关于 Use one AWS Elastic IP for several instances

问题 I need to provide my customers with fixed urls that don't change when the EC2 instances are stopped/started because sometimes we need to change the size of the EC2 and when we restart the instance the public IP has changed. I thought on using Elastic IPs so I can keep the same public IP when the instance is rebooted, but I've seen that Amazon tells you that you only have 5 Elastic IPs. If you ask them they say that they can give you more, but I guess they're not giving you 10.000 of them. How

Assigning static IPs to auto scaled EC2 instance

阅读更多关于 Assigning static IPs to auto scaled EC2 instance

问题 We have a 3rd party integration which needs the EC2 instance IP to be whitelisted. The 3rd party whitelists the IP on their server and then only the EC2 instance can communicate with them. In the case of single instance this works. However when auto scaling kicks in, we would end up in more than 1 instance. These new instances automatically get new IPs for every autoscale action. Is it possible for us to ask AWS to assign IPs from a say a set of 4 predefined Elastic IPs? ( Assumption is that

However, I'm not sure how to do that using --query . I know that the --query option uses JMESPath to filter results, but I have no idea how to tell it to return me all results that do not have an AssociationId . Any help? Thanks. 回答1: You can
