Centurion vs k8s-sidecar-injector: 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, k8s-sidecar-injector is detailed as "Kubernetes sidecar injection service". It is a small service that runs in each Kubernetes cluster, and listens to the Kubernetes API via webhooks. For each pod creation, the injector gets a (mutating admission) webhook, asking whether or not to allow the pod launch, and if allowed, what changes we would like to make to it.
Centurion and k8s-sidecar-injector can be categorized as "Container" tools.
Centurion and k8s-sidecar-injector are both open source tools. It seems that Centurion with 1.72K GitHub stars and 111 forks on GitHub has more adoption than k8s-sidecar-injector with 143 GitHub stars and 19 GitHub forks.
