Ansible - find the maximum value of a hostvar and the name of that host [closed]
My solution: - name: Find max id host set_fact: id_max_host={{ groups['nodes'] | sort('id' | int) | last }} - name: Find max id set_fact: id_max={{ hostvars[id_max_host]['id'] }} It takes the list of hosts in group nodes, sorts by the hostvar 'id' (which it casts to int, because they're usually strings),...

AWS ELB Server certificate trust

why does my domain name immediately switch to showing its ip address once page loads?
In this case I had mistakenly updated the DNS record for forwarding rather than for the @ tag, so it was forwarding to the site.
What happens with data when I stop EBS backed instances
amazon-web-services,amazon-ec2,amazon-ebs

python,amazon-web-services,amazon-ec2,boto,aws-ec2
You can't have an instance without a root volume. So there will always be at least one volume listed in the block device mapping. I'm wrong about that. It has been so long since I launched an instance store backed AMI that I kind of forgot they even existed....
