你们的随身wifi安装Docker应用有没有报错？
有些应用就会报错，无法安装，有些没事，安装的是ddns-go，命令:
docker run -d --name ddns-go --restart=always --net=host -v /opt/ddns-go:/root jeessy/ddns-go
以下报错信息，docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: unable to apply apparmor profile: apparmor failed to apply profile: write /proc/self/attr/apparmor/exec: no such file or directory: unknown.
root@yebeiwifi:~# service apparmor stop
Failed to stop apparmor.service: Unit apparmor.service not loaded.
root@yebeiwifi:~# update-rc.d -f apparmor remove
root@yebeiwifi:~# docker run -d --name ddns-go --restart=always --net=host -v /ddns-go:/root jeessy/ddns-go /bin/sh
