From 09048731000e73b44a0243a0339d8c122eb8a165 Mon Sep 17 00:00:00 2001 From: Brent Baude Date: Thu, 27 Feb 2020 10:59:53 -0600 Subject: rework apiv2 wait endpoint|binding added the ability to wait on a condition (stopped, running, paused...) for a container. if a condition is not provided, wait will default to the stopped condition which uses the original wait code paths. if the condition is stopped, the container exit code will be returned. also, correct a mux issue we discovered.
