KNE should unify the Kernel core pattern for containers so that containers can mount the host's core pattern path (or Kind Node's core pattern path) in the container at a desired path. This will help containers see the core dumps on the host. NOS CLI commands that display core dumps will work seamlessly. It will be better if containers can have a choice for them to be able to mount the core path on the host to a path of their choice in the container so that the containers don't require any additional change.
Maybe a common Node interface implementation that parses the Kernel core pattern and returns the path that the vendor layer can use. Dumping the core directly in the container appears to be distro dependent hence this unification may help.
KNE should also set the "ulimit -c unlimited" allowing apps in the container to dump core.
