Problem Description
When starting a Docker container on a Linux system, the error docker: Error response from daemon: driver failed programming external connectivity on endpoint lucid_banach (an error occurs when port mapping or starting a container): (iptables failed: iptables --wait -t nat -A DOCKER - p tcp -d 0/0 --dport 8080 -j DNAT --to-destination 172.17.0.2:8080 ! -i docker0: iptables: No chain/target/match by that name).
(exit status 1)).
docker: Error response from daemon: driver failed programming external connectivity on endpoint lucid_banach（端口映射或启动容器时报错）: (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8080 -j DNAT --to-destination 172.17.0.2:8080 ! -i docker0: iptables: No chain/target/match by that name).
(exit status 1)).
Cause Analysis:
After starting Docker, and then operating the firewalld, the above error will occur. When firewalld starts or restarts, the Docker rules will be removed from iptables, affecting the normal work of Docker.
solution:
Root user input command:
systemctl restart docker
Restart the docker service to regenerate the custom chain DOCKER.
