Run psychopy on anaconda12/25/2023 ![]() If so, the container probably exited because of this invalid reference. Check if a file listed in the image specification was not found.To diagnose why your container exited, look at the container engine logs: To list all containers that exited with an error code or didn’t start correctly: The number in the brackets is the Exit Code. When a container exits, the container engine’s command-line interface (CLI) displays a line like this. To send Signal 7 (SIGHUP) to a Linux process use the following command: kill - HUB ĭiagnosing Exit Code 1Checking Exit Codes in Kubernetes Diagnosing Exit Code 1 In old terminals based on the RS-232 protocol, SIGHUP was a “hang up” indicating the terminal has shut down. Signal 7 is also known as SIGHUP – a term that originates from POSIX-compliant terminals. When a container terminates with Exit Code 1, the operating system terminates the container’s process with Signal 7. In Unix or Linux operating systems, signals help manage the process lifecycle. For example, if a Java library is running within the container, and the library throws a compiler error, the container might terminate with Exit Code 1.Īn invalid reference is a file reference in the image used to run the container, which points to a nonexistent file. Why Do Exit Code 1 Errors OccurĮxit Code 1 means that a container terminated, typically due to an application error or an invalid reference.Īn application error is a programming error in any code running within the container. We’ll provide several techniques for diagnosing and debugging Exit Code 1 in containers. If you see containers terminated with Exit Code 1, you’ll need to investigate the container and its applications more closely to see what caused the failure. If a pod is unhealthy or frequently shuts down, you can diagnose the problem using the command kubectl describe pod In Kubernetes, container exit codes can help you diagnose issues with pods. In a Unix/Linux operating system, when an application terminates with Exit Code 1, the operating system ends the process using Signal 7, known as SIGHUP. ![]() Exit Code 1 indicates that a container shut down, either because of an application failure or because the image pointed to an invalid file.
