Kubectl Plugins 101
summary
Shows how kubectl plugins work by example: a tiny flags plugin that prints all kubectl-provided environment variables, a Go kill plugin that strips finalizers and force-deletes pods, and the full-featured svcat binary used both standalone and as a plugin to surface Service Catalog brokers/classes/bindings. Covers using client-go, Cobra and Viper, a plugin-utils library to parse global flags, generating plugin YAML from a Cobra app, and alpha-state gotchas like reserved flags and broken boolean flag handling.
