This article shows you how to set up daemon remote connection in docker. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

1. Set daemon listening connection:

Add local default listening port with IP:port mode

Ubuntu:

Modify the daemon configuration: / etc/docker/daemon.json, and add the following line:

The copy code is as follows:

{"hosts": ["fd://", "tcp://0.0.0.0:2375"]} (curly braces are required. If multiple lines are set, each line needs curly braces. If fd:// is set, it is automatically unix socket.

Restart docker:

Systemctl restart docker.service (Ubuntu16.04)

Check that "- H" indicates success.

Root@ubuntu:~# ps aux | grep dockerd root 113731 0.5 0.1 636160 47536? Ssl 10:54 0:00 / usr/bin/dockerd-H unix:///var/-H tcp://0.0.0.0 root@ubuntu:~# netstat-lant | grep 2375 tcp6 00: 2375: * LISTEN

Centos7:

/ etc/docker/daemon.json will be overwritten by the configuration file of docker.service, so adding daemon.json directly will not work. You can have the following settings:

1. Edit the configuration file directly: the docker daemon configuration file in Centos is in / lib/systemd/system/docker.service. Find the following fields and add the following fields. Note that "fd://" cannot be used here, otherwise an error will be reported.

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

Execution

Systemctl daemon-reload systemctl restart docker.service

2. Systemctl edit docker.service, or edit vim / etc/systemd/system/docker.service.d/override.conf (must, not even one line less, and unix:// cannot write fd:// officially)

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

Same execution

Systemctl daemon-reload systemctl restart docker.service

Finally, check whether it is successful. Add the-H parameter and start the port (the default port is 2375, but you can change it):

[root@myrepo docker.service.d] # ps aux | grep dockerd root 5567 8.02.0 632976 37696? Ssl 15:08 0:00 / usr/bin/dockerd-H tcp://0.0.0.0:2376-H unix:///var/run/docker.sock root 6143 0.0 112660 976 pts/0 S+ 15:08 0:00 grep-- color=auto dockerd [root@myrepo docker.service.d] # netstat-lant | grep 2376 tcp6 00: 2376: * LISTEN above is how to set daemon remote connection in docker Have you learned any knowledge or skills?
