Lens | The Kubernetes IDE

Lens is the only IDE you’ll ever need to take control of your Kubernetes clusters. It is a standalone application for MacOS, Windows and Linux operating systems. It is open source and free.

What makes Lens special?

• Amazing usability and end-user experience
• Multi cluster management: support for hundreds of clusters
• Standalone application: no need to install anything in-cluster
• Real-time cluster state visualization
• Resource utilization charts and trends with history powered by built-in Prometheus
• Terminal access to nodes and containers
• Performance optimized to handle massive clusters (tested with a cluster running 25k pods)
• Full support for Kubernetes RBAC

Installation

Download a pre-built package from the releases page. Lens can be also installed via snapcraft (Linux only).

Alternatively on Mac:

brew cask install lens

Development

Prerequisites: Nodejs v12, make, yarn

• make init - initial compilation, installing deps, etc.
• make dev - builds and starts the app
• make test - run tests

Development (advanced)

Allows for faster separate re-runs of some of the more involved processes:

1. yarn dev:main compiles electron's main process app part
2. yarn dev:renderer compiles electron's renderer app part
3. yarn dev:extension-types compile declaration types for @k8slens/extensions
4. yarn dev-run runs app in dev-mode and auto-restart when main process file has changed

Development (documentation)

Run a local instance of mkdocs serve in a docker container for developing the Lens Documentation.

Prerequisites: docker, yarn

• yarn mkdocs-serve-local - local build and serve of mkdocs with auto update enabled

Go to localhost:8000

Developer's RTFM recommended list:

• TypeScript (front-end/back-end)
• ReactJS (front-end, ui)
• MobX (app-state-management, back-end/front-end)
• ElectronJS (chrome/node)
• NodeJS (api docs)
