Capturing the exit status of commands inside the container about ruby-lxc

[ranjib]

Have u tried returning $?.

I use shellout or popen3 API calls for this. You can also use pipes to
communicate , e.g.

runs inside the container. I had a look at #attach and #run_command but
couldn't find a way to capture the exit status. I naively tried somethings
like:

container = LXC::Container.new('foo')
container.start
status = nil
container.attach(wait: true) do
status = system("false")
p status #=> falseend
p status #=> nil

Has anyone had this issue before? Any suggestions to get hold of the exit
status?

Thanks for the suggestion @ranjib. I tried to return $? from the block passed to attach but it doesn't seem to return the same value as $?. I've switched to using IO.pipe to return the exit status as a workaround for now. I think we can close this issue, but would be a good if the gem supported something like this though.
