VS Code devcontainerセットアップのエラーについて about mikanos-devcontainer

[sarisia]

ログのご提供ありがとうございます！

ログから見ますと、コンテナのビルドと起動は正常に終了していますが、 /dev/null が使えないのが原因のようです。

2週間ほど前の Docker for Mac のリリースノートに、以下の修正が含まれていました:

Docker Desktop now ensures the permissions of /dev/null and other devices are correctly set to 0666 (rw-rw-rw-) inside --privileged containers. Fixes docker/for-mac#5527

https://docs.docker.com/docker-for-mac/release-notes/#docker-desktop-331

当 devcontainer は、コンテナ起動時に --privileged を渡しますので、このバグを踏んでいると考えられます。

よって、一度 Docker for Mac を上記リンクから最新版にアップデートしまして、現象が再現するかご確認いただけますでしょうか？

早急にご対応いただき、ありがとうございま！
問題なくビルドできることを確認できました！

Hi @toshi-oliver , thank you for raising the issue!

すみませんが、ログが少なすぎて原因がわかりません。もう少し前後数十行を含んだ詳細なログをご提供いただけますでしょうか？

大変失礼いたしました。
