Have problem when run on AWS ECS after updated to 3.0.2-alpine

[cpanuphan]

After I updated ledermann/rails-base-builder:3.0.2-alpine and ledermann/rails-base-final:3.0.2-alpine.
I met the problem when running my image on AWS ECS with errors /home/app is not writable even I set USER to app on Dockerfile.
Full errors.

Do you have any suggestions?

This may not be due to Ruby 3.0.2, but to the upgrade to Alpine 3.14 made by the Ruby Docker Project two weeks ago.

Alpine 3.14 has some new requirements, e.g. it requires Docker 20.10.0 or later:
https://wiki.alpinelinux.org/wiki/Release_Notes_for_Alpine_3.14.0

There is a discussion about this here:
docker-library/ruby#351
