docker (56) Recv failure: Connection reset by peer

Remember the problem that the docker container cannot access after mapping the host port and the processing process

1. Problem phenomenon

After the docker container is started correctly, check that the host port has been monitored and you can telnet. But the local curl127.0.0.1 returns curl: (56) Recv failure: Connection reset by peer

Docker start command docker run -d -p 8083:8080 --name=tomcat1 345867df0879

Host: The firewall and selinux have been closed, and the ipv4 forwarding has been opened.

Inside the container: Tomcat has been listening on port 8080 normally, and the listening address is 0.0.0.0:8080, allowing other machines to access. And can access tomcat normally

Screenshot below:

2. Processing process

Try to change docker version 19 and 18 are the same, the machine installed is 20

Searching for various solutions, there is no the same situation. Finally found an introduction to delete and re-add the docker0 bridge to solve the problem

(1) Stop the container and stop the docker service

(2) Rebuild the docker0 bridge

[root@localhost ~]# yum install bridge-utils -y

[root@localhost ~]# ip link set dev docker0 down

[root@localhost ~]# brctl delbr docker0

[root@localhost ~]# brctl addbr docker0

[root@localhost ~]# ip addr add 172.16.10.1/24 dev docker0

[root@localhost ~]# ip link set dev docker0 up

[root@localhost ~]# ip addr
