    Architecture and default ports

    1.6 consists of kc-server, kc-agent, kcctl, Console, and platform etcd. It distributes tasks using built-in or external NATS. This differs from the API-driven Operation v2 architecture in 1.7.

    Command differences from 1.7

    • 1.6 uses kcctl operation terminate; 1.7 uses cancel.
    • 1.6 does not provide kcctl status or kcctl doctor; inspect node services and logs instead.
    • Use the 1.6 matrix, NATS configuration, and task model with 1.6 binaries.
