Running into a PKIX error when having one of our pods communicate with another one via https. I have deployed one of our pods via helm-charts, and the other through yaml files via DevOps pipelines.
In both deployments we have created tls-secrets and I can see the secret in the namespace. Seeing as that is already there I would assume I shouldn’t need to add another tls secret to the namspace.

I know the PKIX is a java cacerts issue but not sure how I can load the tls cert into that truststore.

Any help and a step-by-step walkthrough on this would be very beneficial.

Thanks!
