Kubernetes vs Flux CD: What are the differences?
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; 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.
Kubernetes and Flux CD can be categorized as "Container" tools.
Some of the features offered by Kubernetes are:
- 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
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
Kubernetes is an open source tool with 65.5K GitHub stars and 23.3K GitHub forks. Here's a link to Kubernetes's open source repository on GitHub.
