It should definitely fail with error code 1.
does it print a message at the end with something like 
error
in it?

This is one where I got it to fail by using an image that didn’t exist which was expected.

On that first case- it appears the update is indeed succeeding. If the Deployments pods are permanently stuck crash looping, that is unexpected. Do you happen to have a repro that causes this you could share?
s
Hey Luke, I specifically caused the pod to fail by not providing env vars that the node js application inside expects. So the CrashLoopBackOff is expected. What I did not expect was the 
pulumi up
command to pass in that case, as i believe 
kubectl rolling-update
or 
kubectl apply
with a rolling update configured in the deployment with crashing pods on the new revision will eventually fail.
You could simulate by just have a Docker container that runs 
exit 1
as its entrypoint and deploying it out
c
Depends how your liveness/readiness probes are set up
if they’re set up to succeed before the pod crashes, they’ll report success, and we’ll say you succeeded.
we see the first of those outputs all the time under those circumstances.
s
Ahhhhh that makes sense. I had not setup liveness/readiness probes yet. I’ll retry in the morning with those configured. Thanks for the help!
Just wanted to post back in here, adding liveness/readiness checks caused it to fail as expected. Thanks for the help!
