通过docker-java与docker进行通信交互-优快云博客

本文链接：https://blog.youkuaiyun.com/qq_39898191/article/details/137070250

本文介绍了如何通过修改Docker服务配置文件开启通信功能，使用docker-java库进行镜像构建、拉取和容器的创建、启动、查询以及停止和清理操作，包括环境设置和网络模式的管理。

前提需要docker开启通信功能，有多种开启方式，我使用的是修改注册服务时的配置文件docker.service:

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target

1、依赖
