When trying to run the frontend in K8s I am now having issues with requests

It was working previously. Any suggestions on where to look?

DATAHUB_GMS_HOST, KAFKA_BOOTSTRAP_SERVER, and ELASTIC_CLIENT_HOST are all populated.
e
Can you post the list of env variables set for the frontend pod? Are you using our helm charts to deploy to k8s?
s
Yes I am using your helm charts

The env looks correct. @big-carpet-38439 @green-football-43791 any idea why this error would pop up on front-end?
Are you testing on local portforward? Are all requests failing with this error?
s
No port forwarding
This is on initially trying to start up in the cluster
g
it sounds like the frontend is having trouble connecting to either Kafka or GMS?
Are those error logs coming from the frontend container?
Out of curiosity- what is the behavior when you access the frontend? can you view entities?
e
What does frontend try to access on start up? Unlike the other pods, it doesn’t use dockerize to wait for other services to start up.
@green-football-43791
s
The error logs are coming from the frontend container
g
and after that, does the container shut down?
or does it continue to wait?
s
It keeps repeating the same errors. Ultimately it will probably timeout but I did not wait that long. I can wait to see if it does.

Like @early-lamp-41924 mentioned, is it doing pre-flight checks before loading?
e
Can we also get the image and tag being deployed in this pod?
s
@early-lamp-41924 That is what I needed to find my error. There was some bad copy/paste going on. Thank you.
e
Awesome!!! Glad it worked out
g
