containerd vs Rancher Fleet: What are the differences?

What is containerd? An industry-standard container runtime with an emphasis on simplicity,robustness and portability. An industry-standard container runtime with an emphasis on simplicity, robustness, and portability.

What is Rancher Fleet? Manage large fleets of Kubernetes clusters. It is a Kubernetes cluster fleet controller specifically designed to address the challenges of running thousands to millions of clusters across the world. While it's designed for massive scale the concepts still apply for even small deployments of less than 10 clusters. It is lightweight enough to run on the smallest of deployments too and even has merit in a single node cluster managing only itself.

containerd and Rancher Fleet can be primarily classified as "Container" tools.

Some of the features offered by containerd are:

  • OCI Image Spec support
  • OCI Runtime Spec support (aka runC)
  • Image push and pull support

On the other hand, Rancher Fleet provides the following key features:

  • Kubernetes cluster fleet controller
  • Designed for massive scale
  • Lightweight

Rancher Fleet is an open source tool with 338 GitHub stars and 22 GitHub forks. Here's a link to Rancher Fleet's open source repository on GitHub.

What are some alternatives to containerd, Rancher Fleet?

Kubernetes

Kubernetes

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.

Rancher

Rancher

Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.

Docker Compose

Docker Compose

With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.

Docker Swarm

Docker Swarm

Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.

Tutum

Tutum

Tutum lets developers easily manage and run lightweight, portable, self-sufficient containers from any application. AWS-like control, Heroku-like ease. The same container that a developer builds and tests on a laptop can run at scale in Tutum.

Portainer

Portainer

It is a universal container management tool. It works with Kubernetes, Docker, Docker Swarm and Azure ACI. It allows you to manage containers without needing to know platform-specific code.

Codefresh

Codefresh

Automate and parallelize testing. Codefresh allows teams to spin up on-demand compositions to run unit and integration tests as part of the continuous integration process. Jenkins integration allows more complex pipelines.

CAST.AI

CAST.AI

It is an AI-driven cloud optimization platform for Kubernetes. Instantly cut your cloud bill, prevent downtime, and 10X the power of DevOps.

k3s

k3s

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.

Flocker

Flocker

Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.
