Centurion vs RailCar: What are the differences?

Developers describe Centurion as "A mass deployment tool for Docker fleets". A deployment tool for Docker, made by New Relic. Takes containers from a Docker registry and runs them on a fleet of hosts with the correct environment variables, host volume mappings, and port mappings. Supports rolling deployments out of the box, and makes it easy to ship applications to Docker servers. New Relic is using it to run their production infrastructure. On the other hand, RailCar is detailed as "Rust implementation of oci-runtime (by Oracle)". railcar is a rust implementation of the opencontainers initiative's runtime spec. It is similar to the reference implementation runc, but it is implemented completely in rust for memory safety without needing the overhead of a garbage collector or multiple threads.

Centurion and RailCar can be categorized as "Container" tools.
