目前的项目在使用redis、mqtt等开源docker镜像，发现部署完成以后，在本地的镜像目录存在许多777权限的文件，如下所示：/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/bin/redis-benchmark/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/bin/redis-cli/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/bin/redis-server/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/etc/redis.conf/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/etc/redis.conf.template/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/etc/sentinel.conf.template/var/lib/docker/overlay2/7b5f33fc544036a0c6c924e6a59f242d2cf9fd3ed0d5e8c32db9ad8ba7b6d4e2/diff/home/redis/myrun.sh/var/lib/docker/overlay2/310d8d593c47ff9a2269dff2adebb9e1b9b78a5180bb9ce96a144a4b9ea6730a/diff/home/redis/bin/redis-benchmark/var/lib/docker/overlay2/310d8d593c47ff9a2269dff2adebb9e1b9b78a5180bb9ce96a144a4b9ea6730a/diff/home/redis/bin/redis-cli/var/lib/docker/overlay2/310d8d593c47ff9a2269dff2adebb9e1b9b78a5180bb9ce96a144a4b9ea6730a/diff/home/redis/bin/redis-server/var/lib/docker/overlay2/1558dcbe04e6ebf6607dce4f939dbbe054ec91e8687327186689e8b85590ade1/diff/home/redis/myrun.sh/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/bin/redis-benchmark/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/bin/redis-cli/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/bin/redis-server/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/etc/redis.conf/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/etc/redis.conf.template/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/etc/sentinel.conf.template/var/lib/docker/overlay2/739dc31cfea8db596fdbaae739d577f2911c63c1a1e23d1f123a8cb4140f67fe/merged/home/redis/myrun.sh由于公司安全规定，不允许环境中有非必需的777权限文件，我想知道这些文件的777权限是必需的吗？如果不是的话，应该如何治理？望大神们解答，谢谢。
