Who Lives in Our Garden: Understanding Cloud Foundry’s Container Manager
summary
Garden is a Go reimplementation of Warden that splits the container runtime into a server and pluggable back-ends, currently garden-linux, a Windows back-end, and Guardian (runc) as an OCI runtime, with Guardian at 0.9 and 1.0 imminent. Garden-linux can run Docker images by mounting image layers but requires Registry v2 and pulls on each scale event unless using an incubator BOSH release that caches images. Containers use namespaces, cgroups, per-container subnets and firewall rules; cf ssh gives direct shells for debugging.
