Question

I need to set docker to listen to tcp://0.0.0.0/4243 on my host machine running amazon linux (centos). All the documentation I have seen has told me to run the following command

Answer 1

1、edit /usr/lib/systemd/system/docker.service to add two param in the service section:

# vim /usr/lib/systemd/system/docker.service

[Service]

ExecStart=

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

2、reload the configuration,and then restart docker。

# systemctl daemon-reload
# systemctl restart docker

3、to check for success, see if the return the following response。

# ps -ef|grep docker

root 26208 1 0 23:51 ? 00:00:00 /usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
