Logs scrolled past, line after line, until one error stopped everything: Infrastructure Resource Profiles missing the correct internal port.
Infrastructure Resource Profiles define the exact shape of compute, memory, storage, and network access in your environment. They describe how services run, where they run, and what limits they obey. The internal port is a key part of that profile. Without the correct port, traffic inside your system will never reach the service.
An internal port is not the same as an external endpoint. External ports face the outside world; internal ports control communication within your private network or cluster. They let services talk to each other behind the firewall. Configuring this correctly inside an Infrastructure Resource Profile is essential for fast and reliable deployments.
When defining the internal port, make it explicit in the configuration file. Many orchestration platforms will fall back to defaults if you omit it, and defaults are rarely correct across different environments. Every microservice, job runner, or daemon that expects inbound requests from other services must have its internal port set and mapped in the resource profile.
