KSail is a tool that bundles common Kubernetes tooling into a single binary. It provides a VSCode Extension, CLI, AI-Enabled Chat TUI or MCP interface to create clusters, deploy workloads, and operate cloud-native stacks across different distributions and providers.
Setting up and operating Kubernetes clusters often requires juggling multiple CLI tools, writing bespoke scripts, and dealing with inconsistent workflows. KSail removes the tooling overhead so you can focus on your workloads.
No Vendor Lock-In: KSail works with native distribution configurations (Kind's kind.yaml, K3d's config, Talos patches) β you can run the same cluster outside KSail using the underlying tools directly. KSail is a superset that provides a unified workflow while preserving full compatibility with Kind, K3d, and Talos.
- π¦ One Binary β Embeds cluster provisioning, GitOps engines, and deployment tooling. No tool sprawl.
- βΈοΈ Simple Clusters β Spin up Vanilla, K3s, or Talos clusters with one command. Same workflow across distributions.
- π No Lock-In β Uses native configs (
kind.yaml,k3d.yaml, Talos patches). Run clusters with or without KSail. - π₯ Mirror Registries β Avoid rate limits, and store images once. Same mirrors used by different clusters.
- π Everything as Code β Cluster settings, distribution configs, and workloads in version-controlled files.
- π GitOps Native β Built-in Flux or ArgoCD support with bootstrap, push, and reconcile commands.
- βοΈ Customizable Stack β Select your CNI, CSI, policy engine, cert-manager, and mirror registries.
- π SOPS Built In β Encrypt, decrypt, and edit secrets with integrated cipher commands.
- π€ AI Assistant β Interactive chat powered by GitHub Copilot for configuration and troubleshooting.
- π» VSCode Extension β Manage clusters from VSCode with wizards, sidebar views, and command palette.
KSail works on all major operating systems and CPU architectures:
| OS | Architecture |
|---|---|
| π§ Linux | amd64, arm64 |
| macOS | arm64 |
| β Windows (native untested; WSL2 recommended) | amd64, arm64 |
Docker is required for local clusters. Install Docker Desktop/Engine and ensure docker ps works.
Supported distributions run on different infrastructure providers:
| Provider | Vanilla | K3s | Talos |
|---|---|---|---|
| Docker | β (Kind) | β (K3d) | β |
| Hetzner | β | β | β |
See the Installation Guide for detailed installation instructions.
For VSCode users, install the KSail extension to manage clusters directly from your editor. See the extension documentation for features and usage.
# 1. Initialize a new project with your preferred stack
ksail cluster init \
--name <cluster-name> \
--distribution <Vanilla|K3s|Talos> \
--cni <Default|Cilium|Calico> \
--csi <Default|Enabled|Disabled> \
--metrics-server <Default|Enabled|Disabled> \
--cert-manager <Enabled|Disabled> \
--policy-engine <None|Kyverno|Gatekeeper> \
--gitops-engine <None|Flux|ArgoCD> \
--mirror-registry <host>=<upstream>
# 2. Create and start the cluster
ksail cluster create
# 3. Add your manifests to the k8s/ directory
# 4. Deploy your workloads
ksail workload apply -k ./k8s # kubectl workflow
ksail workload reconcile # gitops workflow
# 5. Update cluster configuration (modify ksail.yaml, then run)
ksail cluster update # Apply configuration changes
# 6. Connect to the cluster with K9s
ksail cluster connectKSail generates standard distribution configuration files that you can use directly with the underlying tools:
# After ksail cluster init, you'll find native configs:
# - kind.yaml (for Vanilla/Kind clusters)
# - k3d.yaml (for K3s clusters)
# - talos/ (for Talos clusters)
# You can use these configs directly without KSail:
kind create cluster --config kind.yaml
k3d cluster create --config k3d.yaml
talosctl cluster create --config-patch @talos/cluster/patches.yaml
# Or let KSail manage the lifecycle:
ksail cluster createThis means you're never locked into KSail β you can migrate away at any time or use both KSail and native tools interchangeably.
