Build on Kubernetes with confidence

Carvel provides a set of reliable, single-purpose, composable tools that aid in your application building, configuration, and deployment to Kubernetes.

Pick the tools you need or use the whole suite:

  • ytt

    Template and overlay Kubernetes configuration via YAML structures, not text documents. No more counting spaces, or manual quoting.

  • kbld

    Build or reference container images in Kubernetes configuration in an immutable way.

  • kapp

    Install, upgrade, and delete multiple Kubernetes resources as one "application". Be confident your application is fully reconciled.

  • imgpkg

    Bundle and relocate application configuration (with images) via Docker registries. Be assured app contents are immutable.

  • kapp-controller

    Capture application deployment workflow declaratively via App CRD. Reliable GitOps experience powered by kapp.

  • vendir

    Declaratively state what files should be in a directory.

Experimental Tools

  • kwt Expose Kubernetes overlay network to your machine. No more port mapping, or starting multiple proxies.

  • terraform-provider-k14s Use ytt, kbld, and/or kapp in your Terraform module.

  • secretgen-controller Controller to generate various types of Secrets in-cluster.
