Clair vs Rancher: What are the differences?

What is Clair? Open Source Vulnerability Analysis for your Containers. Clair is a container vulnerability analysis service by CoreOS. It provides the list of vulnerabilities that threaten each container and can sends notifications whenever new vulnerabilities that affect existing containers are released.

What is Rancher? Open Source Platform for Running a Private Container Service. 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.

Clair and Rancher belong to "Container Tools" category of the tech stack.

Some of the features offered by Clair are:

api defines how users interact with Clair and exposes a documented HTTP API.
worker extracts useful informations from layers and store everything in the database.
updater periodically updates Clair's vulnerability database from known vulnerability sources.

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

Manage Hosts, Deploy Containers, Monitor Resources
User Management & Collaboration
Native Docker APIs & Tools

Clair and Rancher are both open source tools. It seems that Rancher with 11.9K GitHub stars and 1.34K forks on GitHub has more adoption than Clair with 5.41K GitHub stars and 696 GitHub forks.

What are some alternatives to Rancher, Clair?

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.

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

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 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

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

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

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

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 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.
