Centurion vs k3s: 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, k3s is detailed as "Lightweight Kubernetes. 5 less than k8s (by Rancher Labs)". Certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. Supports something as small as a Raspberry Pi or as large as an AWS a1.4xlarge 32GiB server.

Centurion and k3s can be primarily classified as "Container" tools.

Some of the features offered by Centurion are:

• Rake application tasks and dependencies
• Talk to a fleet of Docker servers at once
• Does rolling deployment

On the other hand, k3s provides the following key features:

• ARM64 and ARMv7 support
• Simplified installation
• SQLite3 support

Centurion and k3s are both open source tools. It seems that k3s with 7.81K GitHub stars and 483 forks on GitHub has more adoption than Centurion with 1.72K GitHub stars and 111 GitHub forks.
