使用IDEA官方docker插件构建镜像

此方法同样适用于jetbrains系列的其他开发软件

在IDEA中，如果是maven项目，可以使用插件

<plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.2.2</version> </plugin>

或者

<plugin> <groupId>com.spotify</groupId> <artifactId>dockerfile-maven-plugin</artifactId> <version>1.4.13</version> </plugin>

来构建docker镜像，不过还是有些繁琐，可以结合IDEA官方的docker插件，直接快速构建镜像

1 准备

安装docker，Windows可以安装Docker Desktop，CentOS可以参考我之前的文章：CentOS安装docker，安装完成后，需要开启远程访问

1.1 CentOS vi /usr/lib/systemd/system/docker.service # 在 ExecStart 后加上参数 -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

完整信息如下

[Unit] Description=Docker Application Container Engine Documentation= docs.docker After=network-online.target firewalld.service containerd.service Wants=network-online.target Requires=docker.socket containerd.service [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock ExecReload=/bin/kill -s HUP $MAINPID TimeoutSec=0 RestartSec=2 Restart=always # Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229. # Both the old, and new location are accepted by systemd 229 and up, so using the old location # to make them work for either version of systemd. StartLimitBurst=3 # Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230. # Both the old, and new name are accepted by systemd 230 and up, so using the old name to make # this option work for either version of systemd. StartLimitInterval=60s # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel. We recommend using cgroups to do container-local accounting. LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity # Comment TasksMax if your systemd version does not support it. # Only systemd 226 and above support this option. TasksMax=infinity # set delegate yes so that systemd does not reset the cgroups of docker containers Delegate=yes # kill only the docker process, not all processes in the cgroup KillMode=process OOMScoreAdjust=-500 [Install] WantedBy=multi-user.target 1.2 Windows

2 IDEA配置

在idea中，默认自带了docker插件 显示连接成功即可

3 打包项目

这里使用spring boot项目演示，如果是多模块项目，可以结合maven-mvnd这个工具，实现快速打包maven项目

mvnd clean package -DskipTests=true 4 编写dockerfile

点击文件左侧的运行 点击 run 以后，则会开始执行打包操作 切换到服务器也可以查看到 如果需要推送到远程仓库，右键镜像，push 然后选择相应的仓库即可
