Ansible to create aws security group and add to instance
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am creating an EC2 instance. My creation flow is,
Create Ami
Create security group
Create new Instance from AMI and add to security group
My new security group should only contain private ip of a new instance with appropriate ports open
My concern is, How can I create security group and add EC2 Instance private IP if that instance is yet to be created
Is there any way that I can wait for the Instance creation task first and after it is done I fetch the private IP and use that in above task which is "Security group Creation"?
If you have any suggestions please let me know
Thanks

Sure, that's exactly what ec2: (or the newer ec2_instance:) will do when given the wait: yes argument. By using register: ec2_result you can then use ec2_result.instances[0].private_ip_address (as seen here) inside the ec2_group: module to define the rules for the SG.

Thanks for the response but I need to first create an instance, fetch private ip and add it to SG group which can be done by your answer. whereas I also need to attach that SG to an AWS Instance, In short my flow is, 1. Create instance 2. Create SG 3. Add Private Ip of Instance to SG 4. Add SG to that Instance again

Ok, great; I am about 90% certain that one- ec2: wait=yesfollowed by- ec2_group:followed by a second- ec2: instance_ids: ... security_groups: {{ existing_sg + new_sg_id }}will do what you described
