解决docker无法启动的问题

时间：2025-04-13 20:20:15

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=\"" | sudo tee -a /etc/default/docker

导致docker无法启动

sudo service docker restart

查阅了网上好多方法，都不对症，好吧，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//docker (sysvinit)
#   - /etc/init/docker (upstart)
#   - systemd's 

# Use of this file for configuring your Docker daemon is discouraged.

# The recommended alternative is "/etc/docker/", as described in:
#   /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:
#   /v1.11/engine/admin/systemd/#custom-docker-daemon-options
#DOCKER_OPTS="$DOCKER_OPTS --registry-mirror="

然后重启 sudo service docker restart
终于可以了！！你大爷的
