Building an image pipeline using CentOS Stream and Image Builder
summary
Builds reproducible AMIs from CentOS Stream 8 using osbuild/composer, running builds inside ephemeral m5metal or c5metal instances, driving the process from a Jenkins pipeline that invokes an Ansible Linux System Role to run blueprints, pull content from GitHub, produce OCI/Docker/Podman artifacts and upload to S3 then register snapshots as AMIs. Release 26 adds ostree support, images reach AWS Marketplace, and an AWS Parameter Store tag points “latest” to the current AMI so updates replace images without long first-boot updates.
