If you want to access a database service in OpenShift from an application, which approach is recommended?

In OpenShift, applications connect to a database by using the database service’s DNS name and credentials stored in a Secret. This approach leverages in-cluster service discovery so the app can reach the database through a stable endpoint that remains valid even if pod IPs or database pods change. Credentials belong in a Secret, then are injected into the application as environment variables or mounted as files, keeping sensitive data out of code and non-secret configuration. Hard-coding the host ties the app to a fixed, brittle endpoint; using external IPs is similarly fragile and defeats internal service discovery; and ConfigMaps are not designed for secrets, so they risk exposure of passwords. Using the service DNS plus Secrets provides a secure, resilient, and maintainable connection method.
