A Containerd And Friends Update: What’s New In Runtimes?
summary
containerd ships a new stable 1.6 LTS line extended through 2025 and a 1.7 beta that adds a sandbox API to group containers and swap in hypervisor or remote controllers; a new transfer service moves image pulls into the daemon so plugins can pull directly from S3 or other stores. lazy-loading snapshotters (stargz, Sochi seekable OCI, Nydus) speed starts, nerdctl v1.0 + Lima enable Docker-like UX on macOS, Rust crates (seven) and a Rust shim show production use at >5,000 nodes with ~2x memory improvement, and a CNI reorder fixes an IP-exhaustion bug while loopback plugin deprecation is planned.
