Fleet vs Kubernetes: What are the differences?
Fleet: Container management and deployment for your cluster. Fleet is a low-level cluster engine that feels like a distributed init system. With fleet, you can treat your CoreOS cluster as if it shared a single init system; Kubernetes: Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops. Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
Fleet and Kubernetes belong to "Container Tools" category of the tech stack.
Some of the features offered by Fleet are:
- Deploy docker containers on arbitrary hosts in a cluster
- Distribute services across a cluster using machine-level anti-affinity
- Maintain N instances of a service, re-scheduling on machine failure
On the other hand, Kubernetes provides the following key features:
- Lightweight, simple and accessible
- Built for a multi-cloud world, public, private or hybrid
- Highly modular, designed so that all of its components are easily swappable
Fleet and Kubernetes are both open source tools. Kubernetes with 55K GitHub stars and 19.1K forks on GitHub appears to be more popular than Fleet with 2.45K GitHub stars and 309 GitHub forks.
