@devimc please rebase this PR in order to get the CI properly running.

sboeuf

Looks good, but I would prefer the CLI params to be parsed before to call into ps()

sboeuf · 2017-10-30T16:52:43Z

+	SkipArgReorder: true,
+}
+
+func ps(context *cli.Context) error {


I would prefer a function prototype like this:
funcps(containerID, formatstring) error {
since we could reuse this function. Also it is clearer to parse the arguments into the Action callback.

That (not terribly helpful) error seems to be coming from:

https://github.com/containers/virtcontainers/blob/master/pkg/hyperstart/hyperstart.go#L444

There isn't anything else useful in journald fwics.

I've just re-tested with latest runtime + latest agent but same problem :(

(It would be great to get this landed soon as I know how tricky it's been to add the required functionality to various parts of the system).

devimc · 2017-11-27T13:54:09Z

Hi @jodh-intel , still waiting for clearcontainers/agent#90

@jodh-intel it works for me

probably we are doing something different

jodh-intel · 2017-11-28T15:35:36Z

I'm still seeing the problem with image 18860 and also using osbuilder + latest agent. I've tested with busybox and debian docker images. Could you try on another system, or else maybe someone else can try testing this?

devimc · 2017-11-28T16:03:36Z

I added the procps package (like clearcontainers/osbuilder#41), but I'm still seeing ERROR received from VM agent.

jodh-intel · 2017-12-05T10:48:33Z

After a rebase (required due to proxy changes), I am now getting the correct ps output! ;)

Could you rebase and we can get this merged?

Hi @devimc - could you re-push? The CI seems to have got confused.
