Container Built with CloudBuilt and Dockerfile isn't listening on port 8080

[eboraks]

I have a cloudbuild job that failed because the container isn't listening on port 8080. But, when I run the container locally, I have no problem accessing it on port 8080. Here are the error, cloudbuild.yaml, and Dockerfile. I need help figuring out where is the problem. 

Error: Default STARTUP TCP probe failed 1 time consecutively for container "icognition-api-img-1" on port 8080. The instance was not started

cloudbuild:
