I'm taking my first major stab at keystores and It is not as simple to workout as it reads at high level.
My use case:
Implement MTLS for java microservices A and B using microprofile (e.g. helidon mp 2x.)
Microservice A is deployed to a Kubernetes cluster behind an nginx ingress controller with a wild card TLS certificate applied for domain *.myapps.com .
Microservice A is accessible via https://apps.myapps.com/microservicea/api/dosomething
No explicit SSL configuration has been applied in Microservice A's config files thus internally it is running in Non SSL mode.
Microservice B is in development and running on my development pc.
Microservice B has a rest client to microservice B https://apps.myapps.com/microservicea/api/dosomething
I have the .crt and .key files for *.myapps.com
Question:
What steps do I need to take to ensure both microservices have the necessary certificates to communicate with each other and get past the SSL handshake exceptions?
