docker无法启动问题
由于下载jenkins出现问题TLS handshark timeout
用了网上的一个方法
$ echo "DOCKER_OPTS=\"\$DOCKER_OPTS --registry-mirror=http://f2d6cb40.m.daocloud.io\"" | sudo tee -a /etc/default/docker
导致docker无法启动
sudo service docker restart
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

只有对比能用的服务器上面的docker配置看看有什么问题，
终于在/etc/default/中的docker文件，
需要把文件中的最后一行注释掉
# Here in Debian, this file is sourced by: # - /etc/init.d/docker (sysvinit) # - /etc/init/docker (upstart) # - systemd's docker.service # Use of this file for configuring your Docker daemon is discouraged. # The recommended alternative is "/etc/docker/daemon.json", as described in: # https://docs.docker.com/v1.11/engine/reference/commandline/daemon/#daemon-configuration-file # If that does not suit your needs, try a systemd drop-in file, as described in: # https://docs.docker.com/v1.11/engine/admin/systemd/#custom-docker-daemon-options #DOCKER_OPTS="$DOCKER_OPTS --registry-mirror=http://f2d6cb40.m.daocloud.io"
然后重启
sudo service docker restart
终于可以了！！
