Debug Docker Container Immediately Exit Code 137
Exit Code 137 is not a crash; it is a forced termination via SIGKILL. This means the Linux Out-of-Memory Killer intervened. We bypass generic troubleshooting and dive directly into cgroup analysis. Learn the exact dmesg patterns indicating OOM intervention and how to correlate the kernel output with your container ID. We demonstrate setting precise memory and swap limits using Docker Compose and analyze application-level memory consumption, specifically tuning Java Virtual Machine heap sizes and Node.js maximum old space. Implement immediate, verifiable resource constraints to stabilize production environments.
