Introduction to System Containers. As part of our effort to reduce the number of packages that are shipped with the Atomic Host image, we faced the problem of how to containerize services that are needed before Docker itself is running. The result: system containers, a way to run containers in production using read only images.Oct 04, 2021 · etcd-cloud-operator. Maintained by a former CoreOS engineer and inspired from the etcd-operator designed for Kubernetes, the etcd-cloud-operator automatically bootstraps, monitors, snapshots and recovers etcd clusters on cloud providers. The primary concern of just issuing USER XYZ in the Dockerfile, or even trying to be clever with adjusting permissions before dropping privileges would be the upgrade path for users already managing the user ID or permissions with currently available features of the runtime.
