Custom CentOS AMI builds on AWS
summary
Automated CI builds CentOS AMIs on AWS using Packer builders and Git-based pipelines (GitHub Actions in demos) that output an AMI ID and publish it (marked public and copied per-customer with encryption). Images are EBS-backed, start from CentOS release tarballs (no official CentOS 8 AMI available at the time), provision with scripted chroot steps, and validate with Goss tests (optionally Test-Kitchen). The pipeline achieves reproducible AMIs and the build+test+publish flow runs end-to-end.
