Mac OS: 10.13.3(17D47) Docker for Mac: Version 17.12.0-ce-mac49 (21995) ちょっと古いdocker-compose.ymlには結構 volumes: - /etc/localtime:/etc/localtime:ro みたいな記述が入ってるんだけど、これが以下のエラーを出す。 Mounts denied: The path /etc/localtime is not shared from OS X and is not known to Docker. You can configure shared paths from Docker -> Preferences... -> File Sharing. See https://docs.docker.com/docker-for-mac/osxfs/#namesp
