- Understanding the Error
- Exit 137 indicates a container received a SIGKILL signal
- The error occurs when the container runs out of memory
- Exit codes range from 0 to 255, with higher values having specific meanings
- Common Causes
- Linux OOM killer terminates containers when memory usage exceeds limits
- Memory limits set using --memory option can trigger the error
- Poorly optimized applications can cause excessive memory consumption
- Resource constraints on host machines can trigger the error
- Solutions
- Adjust container memory limits to ensure sufficient resources
- Mount configuration files from outside the container
- Monitor container usage and resource consumption
- Add more RAM to the host machine
- Optimize applications for memory efficiency
- Implement health checks and logging for container monitoring
- Consider adding swap space for persistent memory issues
