Can you trigger an automatic memory dump on an OOM exception in .NET Core on Kubernetes?


You have 2 ways to do this.

For both ways to work, .Net Core needs to support a flag which tells it to dump on crash and a flag to pass it the path of where to dump.

  1. Have a sidecar with shared storage on the microservice pod. In the sidecar, have a script that monitors the storage and copies the files dumped there to a location like a s3. I guess this is the one mentioned in the Java link

  2. Have a storage common storage attached to all the pods of a Microservice, something like a NFS, in amazon's case, EFS. Use that efs in your deployment and make the .Net dump to that storage. Then it's only a matter to getting the dump out which you can do via a debug pod or a jumphost attached to the EFS
