docker端口映射或启动容器时报错Error response from daemon: driver failed programming external connectivity on end

现象：

[root@localhost ~]# docker run -d -p 9000:80 centos:httpd /bin/sh -c /usr/local/bin/start.sh
d5b2bd5a7bc4895a973fe61efd051847047d26385f65c278aaa09e4fa31c4d76

(exit status 1)).

[root@localhost ~]# docker start d5b2bd5a7bc4

原因:

docker服务启动时定义的自定义链DOCKER由于某种原因被清掉
重启docker服务及可重新生成自定义链DOCKER

解决:

重启docker服务后再启动容器
systemctl restart docker  (重点)
docker start foo
