Docker container root disk default size (AWS ECS)

Thank you for your reply. I do read your link before. I have already add more volume, say 100GB on /dev/xvdcz. My problem is that after that, once I run a container, in side the container it still only see 10GB as the default value. And every time the container hit 10 GB, it can not have more storage.
I have been looking this Increase container volume(disk) size to change the default setting but it is still not work.

Am I missing something in between?
