If you look at the output of docker ps -athe captured exit code is indeed 0.
I think the rule that you cannot SIGKILL pid 1 from 'man 2 kill' only applies to the actual host init process, not whatever command docker is running as pid 1 inside the container, because docker already handles gracefully pid 1 completing. It would be nice if foreground 'docker run' as well as 'docker wait' were able to report any signal completion status from the initial docker run process. In particular, if foreground 'docker run' and 'docker wait' killed themselves with the exact same signal pid 1 completed with, then the command signal completion information would propagate to the caller completely unchanged.
Thus the caller gets the exact same completion information whether or not the command was run through docker. You can test this as such.
The right way to run a process in the container is to make sure it's not wrapped in a shell command, or at least exec'd from the shell command But if you append another command to it it's apparent the kill has no effect. In fact I cannot make the above example die with any signal value. So I now agree with the statement that this is not a bug.

However, if you still want to detect signal completion of a docker run command natively, you have to write a container wrapper that runs the command in a child process and then communicates the signal completion to the docker caller somehow.
It would be nice if docker handled this automatically when desired. Yes, this is going to be highly dependent on what's running. It would seem Perl does not do this. Some things do not load their default signal handlers if it is running as PID 1, and so they would need to be setup manually. Then the correct error is returned. The issue here is that doing it this way I can't chain multiple commands. Skip to content.

Sign up.During a crash, container will show an exit code that explains the reason for its crash. When the MySQL process running in the container exceeded its memory usage, OOM-killer killed the container and it exited with code Get world class Docker management services at affordable pricing. Each Docker container has a log file associated with it.
These log files store all the relevant information and updates related to that container. Examining the container log file is vital in troubleshooting its crash. In Docker architecture, the containers are hosted in a single physical machine. Error in Docker usually happens due to 2 main out-of-memory reasons:.
By default, Docker containers use the available memory in the host machine. An application can use up too much memory due to improper configuration, service not optimized, high traffic or usage or resource abuse by users.

In the documentation here it shows a pod using too much memory and is promptly killed. When this happens it shows the error reason as "OOM" and error code as in the docs.
When I go through similar steps myself, the termination reason is just "Error", though I do still get the error code. Is there a reason this was changed? OOM is very clear on what happened while "Error" can send people down a wild chase trying to figure out what happened to their pod - hence me filing this issue. For reference the script ran in my docker image just eats memory until it the container gets killed. Two of us spent the past hour chasing error left and right. I'm facing the same issue here.
Kube: v1. I had the same issue with kubernetes v1. I think this could happen when a container liveness probe fails. If yes, describe the pod and look for events section. ApsOps nope, I didn't setup any LivenessProbe nor it appears in the pod description. I have the same Exit status showing up all over the place. One of the things that I discovered was a service phpmyadmin which was limited to Mi in ram that was eating 2Gb of RAM.
How it managed to do that I don't know but it was causing other probes on the same VM to crash:. I have frequent crashes of the same sort that occur on different VM's though so I can't place my finger exactly on the phpmyadmin service which I completely removed now to test thing out. All the pods that crash have liveness and readiness in place btw.
I'm starting to feel like this is a gcloud issue of some sorts as I can't get a stable system even after 2 months of running a decently accessed application. I have seen this as well in my setup. Does code only signal about OOMKill?
It is not clear for me from Docker and K8 code. Issues go stale after 90d of inactivity. Stale issues rot after an additional 30d of inactivity and eventually close. I am having issue where my java process is saying " abnormal termination with error code "Process destroyed without shutdown hock.
Stale issues rot after 30d of inactivity. Rotten issues close after an additional 30d of inactivity. Rotten issues close after 30d of inactivity. I was having the same problem, first looked like it was a problem with resources in the pod, but eventually, liveness probe was failing and it happened due to Istio rules which were blocking health checks.
I suspect its because of liveliness probe failing, but not sure why it should exit with code which is for OOM. Skip to content.If a container is no longer running, use the following command to find the status of the container:. With exit codeyou might also notice a status of Shutdown or the following failed message:. This can be due to a couple possibilities seen most often with Java applications :.
To test whether your containerized application correctly handles SIGTERMsimply issue a docker stop against the container ID and check to see whether you get the "task: non-zero exit ". This is not something to test in a production environment, as you can expect at least a brief interruption of service. Best practices would be to test in a development or test Docker environment.
The application hit an OOM out of memory condition. With regards to OOM condition handling, review the node's kernel logs to validate whether this occurred. This would require knowing which node the failed container was running on, or proceed with checking all nodes. Run something like this on your node s to help you identify whether you've had a container hit an OOM condition:.
Review the application's memory requirements and ensure that the container it's running in has sufficient memory. Conversely, set a limit on the container's memory to ensure that wherever it runs, it does not consume memory to the detriment of the node.
