Flux CD vs RancherOS

RancherOS vs Flux CD: What are the differences?

RancherOS: A Lightweight Container Operating System. It makes it simple to run containers at scale in development, test and production. By containerizing system services and leveraging Docker for management, the operating system provides a very reliable and easy to manage containers; Flux CD: The GitOps operator for Kubernetes. It is a tool that automatically ensures that the state of your Kubernetes cluster matches the configuration you’ve supplied in Git. It uses an operator in the cluster to trigger deployments inside Kubernetes, which means that you don’t need a separate continuous delivery tool.

RancherOS and Flux CD are primarily classified as "Operating Systems" and "Container" tools respectively.

Some of the features offered by RancherOS are:

• Lightweight
• Rancher Integration
• Kuberenetes Integration

On the other hand, Flux CD provides the following key features:

• Describe the entire desired state of your system in Git. This includes apps, configuration, dashboards, monitoring, and everything else
• Use YAML to enforce conformance to the declared system. You don’t need to run kubectl because all changes go through Git. Use diffing tools to detect divergence between observed and desired state and receive notifications
• Everything is controlled through pull requests, which means no learning curve for new developers. Just use your standard PR process. Your Git history provides a sequence of transactions, allowing you to recover system state from any snapshot. Fix a production issue via pull request rather than making changes to the running system

RancherOS is an open source tool with 5.85K GitHub stars and 599 GitHub forks. Here's a link to RancherOS's open source repository on GitHub.
