Steps for docker container exit error code

Sometimes some docker containers exit after a period of execution. In order to find out the reason, check the error code of the docker container exit. The specific steps are as follows:

1. Find the exited container. You can find it in the following two ways:

docker ps --filter "status=exited"

docker ps -a | grep container name

2. Execute the docker inspect container id command to view the exited container information

docker inspect container id, check the State part

The State section shows the status of the container, OOMKilled, ExitCode and other information. The following is a common ExitCode of Docker

• Exit Code 0 : In many cases, it may just be the normal exit of the program
• Exit Code 1 : Application startup failed, such as failure to connect to the database at startup, failure to register nacos, etc.
• Exit Code 137 : The container received a SIGKILL signal. For example, the system killed the container when the container usage was too high. It could also be a Dockerfile problem, where a non-existent file was accessed, such as ENTRYPOINT ["java","-jar","sample.ja"] missing the regexp.
• Exit Code 139 : The container received a SIGSEGV signal, such as a program accessing memory beyond the bounds, but the running system did not catch the corresponding error. Exit Code 255: An error occurred in the container, but the cause of the error is uncertain. In this case, you can view the container logs through docker logs container id to see if you can find any clues.

PS: Let’s take a look at the errors encountered when creating a docker container
