borescope

borescope gives you a prompt that feels like bash but talks to a Kubernetes
charm workload container's Pebble instead of a real shell — handy when the
rock has no shell at all. It uses your existing Juju authority (juju ssh),
needs no kubectl/cluster-admin, and puts Pebble's vocabulary (services, logs,
plan, ...) front and centre alongside familiar commands (ls, cat, grep, ...).
