How to Set Up and Use Ksail
KSail is an all-in-one Kubernetes SDK and CLI that lets you create, manage, and operate Kubernetes clusters across multiple distributions — Kind, K3d, Talos, VCluster, KWOK, and AWS EKS — with a single tool. It includes built-in GitOps support via Flux and ArgoCD, secrets management with SOPS and Age encryption, manifest validation with Kubeconform, and an integrated MCP server and AI chat assistant. This makes KSail useful for developers who want to spin up local development clusters, manage GitOps pipelines, and interact with their Kubernetes workloads through natural language via Claude or GitHub Copilot.
Prerequisites
- Docker Desktop or a cloud provider account (EKS) — KSail's local modes require Docker
- Go 1.26.1+ if installing from source, or Homebrew for macOS/Linux binary install
- kubectl installed and available in PATH for cluster interaction
- An MCP-compatible client such as Claude Desktop, Claude Code, or VS Code with GitHub Copilot for AI-assisted operations
Install KSail via Homebrew
Install the KSail binary using Homebrew on macOS or Linux. This is the simplest installation method and keeps KSail up to date.
brew install --cask devantler-tech/tap/ksailScaffold a new cluster project
Use ksail cluster init to generate a project scaffold with sensible defaults. This creates the directory structure and configuration files for your cluster.
ksail cluster init --name my-appCreate the cluster
Spin up the Kubernetes cluster locally using Docker. KSail handles the Kind/K3d bootstrapping, networking, and initial GitOps engine deployment automatically.
ksail cluster createConnect to the cluster with K9s
Open the built-in K9s terminal UI to browse and interact with cluster resources visually.
ksail cluster connectConfigure the KSail MCP server for Claude
Install the KSail plugin for Claude Code CLI, which registers the MCP server and enables natural-language cluster management.
/plugin marketplace add devantler-tech/ksail
/plugin install ksail@ksailKsail Examples
Client configuration
claude_desktop_config.json entry to run KSail as an MCP server subprocess. KSail must be installed and accessible in PATH.

}Prompts to try
Natural-language prompts for managing Kubernetes clusters through an AI assistant connected to KSail.
- "Create a new Kind cluster named dev-cluster with Flux GitOps enabled"
- "Show me all pods in the kube-system namespace and their status"
- "Deploy the manifests from ./k8s/base using Kustomize"
- "Rotate the SOPS encryption keys for my cluster's secrets"
- "Validate all Kubernetes manifests in the ./manifests directory against the 1.30 schema"
- "Stop and delete the my-app cluster"Troubleshooting Ksail
ksail cluster create fails with Docker not found
KSail's local cluster modes (Kind, K3d) require Docker to be running. Start Docker Desktop and verify with `docker info`. If using Talos or EKS, consult the KSail docs for cloud provider credential setup.
brew install fails: tap not found
Run `brew tap devantler-tech/tap` first to add the custom tap, then `brew install --cask ksail`. Alternatively, install from source with Go: `go install github.com/devantler-tech/ksail/v7@latest`.
GitOps reconciliation does not start after cluster creation
Ensure your Git repository URL is correctly set in the cluster init config and that the Flux or ArgoCD bootstrap has SSH or HTTPS access to the repo. Run `ksail cluster status` to inspect the GitOps engine's reconciliation state.
