--------------------------------------------------------------
We do need to build a new CLC because upgrade lets user modify the
artifacts/env/configs of their service. Likely scenario is that the version of
the component (docker based) changed. I haven't tested with a docker based app,
but I think this re-init should work seamlessly in the docker case. If it
doesn't then that would be a bug.
I don't clearly understand [~eyang]'s comments on the improvement that is being
proposed.
was (Author: csingh):
I looked at the {{ContainerImpl}} code and I think re-init already uses the
re-launch logic.
As [~shaneku...@gmail.com] pointed out, re-init first will deactivate the
existing container then do a relaunch with a new {{ContainerLaunchContext}}.
