Hi Everyone,
We are currently experiencing an issue with our Oracle OKE 1.29 cluster related to inter-service communication within the cluster.
Issue Description
Our application, deployed on the OKE cluster, has services that need to communicate with each other using their public URLs over HTTPS from within the cluster containers. However, when a service tries to hit its domain/URL from a container using HTTPS, the request fails.
Observations
- Communication with external domains hosted outside the cluster works without issues, confirming there is no ACL blocking HTTP or HTTPS traffic for outgoing requests.
- We are using NGINX ingress controller for traffic routing within the cluster.
Request for Assistance
We would like your help in identifying and resolving the issue. Specifically:
- Could there be any specific configurations or limitations in OKE 1.29 that block HTTPS traffic for internal domains from within the cluster?
- Are there adjustments required in the NGINX ingress controller or other network settings to enable HTTPS traffic for inter-service communication?
We appreciate your support in resolving this matter and look forward to your guidance.
