Getting core dump in ECS using Bottlerocket OS

[josh-kim-resolver]

I'm trying to configure Bottlerocket OS to generate core dumps when containers crash in ECS. My goal is to create a bind mount between the host and the container so that the core dumps are preserved after a crash. To do this, I need the core dumps to be saved in a specific directory where the bind mount is created. However, I'm facing an issue configuring /proc/sys/kernel/core_pattern on the host, which is used to specify the core dump location, because it's read-only and I can't find a way to work around this limitation.

I read about bootstrap containers in the documentation and am wondering if they could be used to modify the core_pattern file. Any help or guidance on how to get core dumps in ECS using Bottlerocket OS would be greatly appreciated. Thanks!
