K3s is a lightweight Kubernetes distribution designed for resource-constrained environments such as edge computing and IoT. It is also a good choice for development and testing environments. K3s is smaller, faster, and easier to use than stock Kubernetes, but it is not a replacement for Kubernetes in all cases.
We've built a platform to automate incident response and forensics in AWS, Azure, and GCP you can grab a demo here. You can also download free playbooks we've written on how to respond to security incidents in AWS, Azure, and GCP.
Here are some of the key features of K3s:- Lightweight: K3s has a smaller footprint than other Kubernetes distributions. This makes it ideal for resource-constrained environments.
- Easy to install and manage: K3s can be installed with a single command. It is also easy to manage, with a simple command-line interface.
- High availability: K3s can be configured for high availability, with multiple control plane nodes.
- Air gap installation: K3s can be installed in an air gap environment, without internet access.
- Worker node deployment: K3s can be used to deploy worker nodes to the edge.
K3s vs. Kubernetes
K3s and Kubernetes are both Kubernetes distributions, but they have some key differences. K3s is smaller, faster, and easier to use than Kubernetes, but it is not as feature-rich. Kubernetes is better for complex deployments and those that require high availability.
When to use K3s
K3s is a good choice for the following:
- Edge computing and IoT: K3s is small and efficient, making it ideal for resource-constrained environments.
- Development and testing: K3s is easy to install and manage, making it a good choice for development and testing environments.
- Small workloads: K3s is sufficient for small workloads that do not require all the features of Kubernetes.
When to use Kubernetes
Kubernetes is a good choice for the following:
- Complex deployments: Kubernetes is more feature-rich than K3s, making it better suited for complex deployments.
- High availability: Kubernetes can be configured for high availability, with multiple control plane nodes and worker nodes.
- Large workloads: Kubernetes can handle large workloads more efficiently than K3s.
