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.spotifygroupId>
	<artifactId>docker-maven-pluginartifactId>
	<version>1.2.2version>
plugin>

或者

<plugin>
	<groupId>com.spotifygroupId>
	<artifactId>dockerfile-maven-pluginartifactId>
	<version>1.4.13version>
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=https://docs.docker.com
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
