(base) ? UTF docker start 913 Error response from daemon: Mounts denied: The path /var/mediawiki/mysql 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/#namespaces for more info.
解决：
原来的写法：-v /var/mediawiki/images:/images
替换为：-v /private/var/mediawiki/images:/images
/var in macOS is a symbolic link into /private. That is also true for /tmp:
$ ls -ld /tmp /var lrwxr-xr-x@ 1 root wheel 11 Jan 26 16:18 /tmp -> private/tmp lrwxr-xr-x@ 1 root wheel 11 Jan 26 16:18 /var -> private/var
