krepl — An interactive REPL for Kubernetes

krepl is an interactive REPL for managing Kubernetes clusters and is inspired by Click. One of its goals is best-effort Click compatibility, so Click users can also use krepl in an intuitive way. It maintains context, namespace, and selected object state between commands, so you do not need to pass --context and --namespace flags or object names on every invocation. It also supports a few capabilities Click does not currently support, including editing Kubernetes objects and running without a dependency on the kubectl binary.
