Istio is built out of a number of repositories. This page provides some guidance to help orient yourself.

• istio/api. Holds the definitions for the Istio configuration model (it's API)

• istio/pkg. Holds common Go packages used by many other repos.

• istio/bots. Holds the Go sources for automation bots used by the Istio project.

• istio/tools. Holds the Go sources for tools used by the Istio project.

• istio/istio. The primary Istio repo where we produce release and track issues. This currently includes sources for the major Istio components (Pilot, Galley, Citadel, Mixer), but we plan on moving those out to separate repos.

• istio/operator. The Go sources for the Istio operator component.

• istio/installer. The source material for the Istio installer.

• istio/cni. The Go sources for the Istio CNI plugin.
