@kodekloud: Docker Exit Code 137 Explained in 2 Minutes (Interview Question) Docker exit code 137 isn't a crash — it's a crime scene. 👀 Your container didn't die naturally. Something sent SIGKILL (128 + 9 = 137), and 9 times out of 10 it's the Linux OOM killer freeing memory the hard way. In this short, I break down exactly how to confirm it: check docker inspect for the OOMKilled: true flag under State, then verify on the host with dmesg or journalctl -k for kernel OOM logs. If both come back clean, look at Docker stop timeouts, orchestrator force-kills, or a manual docker kill. Bonus: exit 143 = SIGTERM (graceful stop request), exit 139 = segfault. Don't confuse them or you'll debug the wrong thing. ▶ Follow for more Docker, Kubernetes & DevOps interview shorts. #docker #devops #kubernetes #docker137 #exitcode137 #oomkill #sigkill #containers #linux #devopsengineer #dockerinterview #devopsinterview #kubernetesinterview #cloudengineer #sre #backenddev #coding #programming #techinterview #softwareengineer
