1、启动docker时报错：
Error response from daemon: driver failed programming external connectivity on endpoint trojan (d3a667de7338ff818977ec2eda6bd0b21562055cd0077a2b3a41fb1927767b87): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 1443 -j DNAT --to-destination 172.17.0.2:443 ! -i docker0: iptables: No chain/target/match by that name.
2、解决办法：
systemctl stop docker.service
iptables -t nat -F
ifconfig docker0 down
systemctl restart docker.service
docker ps
3、容器随docker服务一起自启动
docker update --restart=always <CONTAINER ID>
systemctl restart docker.service
docker ps
# 方法二：
docker run -dit -p 6379:6379 --restart always redis
