chroot内でdockerを実行する方法
Arm64にdebianストレッチをインストールしましたAndroid電話。 here からこれらの手順に従ってdocker-ceをインストールしました。
Dockerの開始時:: systemctl start docker
このエラーを返します:: Running in chroot, ignoring request.
service docker statusを使用して確認すると[FAIL] Docker is not running ... failed!が表示されます
dockerdを使用して実行すると、このエラーが表示されます::

Android電話のchroot内で実行するにはどうすればよいですか？
そのため、dockerを起動できませんでした。chrootで実行すると、システムが完全に起動しません。サービスを管理するプロセスが実行されていないため、systemctlコマンドは開始リクエストを無視します。
Dockerデーモンを直接起動することをお勧めします：dockerd [arguments]。 supervisordのようなプロセスマネージャーを使用することもできます。
