ENOTFOUND when creating an alarm trigger

[mluds]

I'm trying to create a cron trigger using this command: wsk trigger create mytrigger --feed /whisk.system/alarms/alarm --param cron '0 * * * *'

However I get what seems to be a DNS related error:

ok: deleted trigger mytrigger

The host parameter looked off so I checked the environment configuration, but it looks ok.

root@openwhisk-alarmprovider-fccf54c4f-vxwzf:/# echo $ENDPOINT_AUTH
openwhisk.mydomain.org:443
root@openwhisk-alarmprovider-fccf54c4f-vxwzf:/# echo $ROUTER_HOST
openwhisk.mydomain.org:443

I also verified that DNS does work.

> dns.resolve('www.google.com', (error, addresses) => { console.error(error); console.log(addresses); });

I'm running this on Openwhisk installed on Kubernetes using the Helm chart, and configured to use the openwhisk/alarmprovider:2.2.0 image. Here is my Helm config (I changed some variables, including the domain, for security reasons):

Any help would be appreciated.

This error "message": "getaddrinfo ENOTFOUND https https:443", suggests the the API host for the alarm service wasn't configured or cannot be resolved correctly. The action whisk.system/alarms/alarm needs to be able to reach the Alarm API host.

I wasn't able to track down the exact issue, but upgrading openwhisk-deploy-kube from commit 3899c47cd87b06c7fd3b1753a06b3d630684b364 to f58729b8265fe47f663dd1fd4e8b798391c45e86 seemed to resolve it. Thank you
