基础环境

Docker开启远程API

修改docker.service文件

配置生效

重新启动Docker服务

开启2375端口

测试--curl http://192.168.172.128:2375/version

# 基础环境 #

> Idea: 2019.1.3

> Docker: 20.10.2

> Centos: 7.8

# Docker开启远程API #

## 修改docker.service文件 ##

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

需要修改的部分：

ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

修改后的部分：

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

## 配置生效 ##

> systemctl daemon-reload

## 重新启动Docker服务 ##

> systemctl stop docker  
> systemctl start docker

## 开启2375端口 ##

firewall-cmd --zone=public --add-port=2375/tcp --permanent
    firewall-cmd --reload

## 测试--curl http://192.168.172.128:2375/version ##
