Yep. My team wrote this in 2014 or 2015, the features and conf file almost identical. We’d had to extract out of a custom Ansible module to better do the full dance.

Shared the approach with AWS ProServe, Stelligent (now Mphasis), and others as well, also discussed briefly with Atlassian architects probably in 2015-2016 timeframe.

Surprised if this isn’t one of those lots of folks just knocked out and didn’t think much of, and really should be in AWS toolkit.

And there are commercial products that do this and more that have been around for years [0].
