I know there are many questions concerning this aspect... but until now I could not find any answers. I tried two images (Apache Solr and Neo4J). Tried different namespaces, clusterIP, edit /etc/hosts, ingress, tunnel, minikube ip and all my requests got no response.
I tried these images standalone in Docker and they answer properly... with localhost, 127.0.0.1 and my ethernet IP - in case 192.168.0.15. I guessed that could be an internal configuration (from Sol, Neo4J) to allow requests only from localhost... but as they replied the calling from IP address and through a custom domain I set in /etc/hosts, I turned to kubernetes configuration.
Below are the following steps and environment:
1) MacOS 10.15 Catalina
2) minikube version: v1.24.0 - commit: 76b94fb3c4e8ac5062daf70d60cf03ddcc0a741b

The bash steps where executed in that order. I have each yaml configuration in a separated file. I joined they here as just one yaml just to expose then.
What part or parts of the setup process or configuration process am I missing?
Below follows the kubectl describe all with only neo4j. I tried http, https request from all possibles IP... Connected to each pod and perform a curl inside the pod... and got successfully responses.
