Upon some digging, one of the reasons this happens is that we are trying to run an arm64 image (built on M1 MacBook) on a different host platform.\n\nGCP does mention on this page here that Executables in the container image must be compiled for Linux 64-bit. Cloud Run specifically supports the Linux x86_64 ABI format.\n\nI guess that explains why building the image on Cloud Build works from the other answer in this post.","confidence":0.95,"source":"stackoverflow","source_url":"https://stackoverflow.com/questions/66127933/cloud-run-failed-to-start-and-then-listen-on-the-port-defined-by-the-port-envi","votes":45,"created_at":"2026-04-19T04:51:19.424808+00:00","updated_at":"2026-04-19T04:51:19.424808+00:00"}
