I had the same issue and it was because of invalid characters. My image name was keycloak_blog. I changed it to keycloakblog and it started to work

Your question says: I am trying to do a httpRequest from library to people-service

From that I assume the request would be initiated in library. Then the URL should look like http://people-service:8080. But from the error message I'd assume your library is not able to run http requests - regardless of where they are going to, which is a bit strange. Investigate on that first, using simple urls like http://stackoverflow.com (which will return http status 301).
