idea连接docker实现一键部署

1.修改docker配置文件，打开2375端口

[root@s162 docker]# vim /usr/lib/systemd/system/docker.service #查找 ExecStart，在末尾添加 #后面加上-H tcp://0.0.0.0:2375 [root@s162 docker]# systemctl daemon-reload [root@s162 docker]# systemctl start docker ## 查看2375端口是否启用 [root@s162 docker]# lsof -i:2375 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME dockerd 27021 root 5u IPv6 352598799 0t0 TCP *:2375 (LISTEN)

2. Idea安装配置docker插件

2.1. idea-plugins市场 安装docker插件

略…

2.2. 配置docker

3.springboot项目部署到docker服务器

3.1. 编写docker/dockerfile

3.2.maven添加docker-maven-plugin插件

<plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <!--指定生成的镜像名，如果不指定tag,默认会使用latest--> <imageName>jhs/${project.artifactId}:${project.version}</imageName> <!--添加额外的指定标签, 非必须--> <!-- <imageTags> <imageTag>${project.version}</imageTag> </imageTags> --> <!-- 指定 Dockerfile 路径 ：项目根路径下--> <dockerDirectory>${project.basedir}/docker</dockerDirectory> <!--指定远程 docker api地址--> <dockerHost>http://192.168.129.162:2375</dockerHost> <!-- copy资源 --> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> <!--docker build dockerfile时：设置镜像创建时的变量 --> <buildArgs> <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE> </buildArgs> </configuration> </plugin>

3.3. docker:build

使用命令$ mvn clean package docker:build -Dmaven.test.skip=true构建镜像，在docker服务器上查看镜像是否上传成功：

3.4 docker:tag

docker命令行格式为：#docker tag <imageId or imageName> <nexus-hostname>:<repository-port>/<image>:<tag>

插件配置 <configuration>补充配置：

<configuration> <image>jhs/${project.artifactId}:${project.version}</image> <!-- docker tag 打标签--> <newName>192.168.129.160:5000/${project.artifactId}:${project.version}</newName> </configuration>

为镜像打上tag标签，为后续的push做准备：mvn clean docker:tag -Dmaven.test.skip=true -DskipDockerBuild

3.5 docker:push

插件配置 <configuration>补充配置：

<configuration> <!-- docker push 推送到远程镜像仓库--> <!-- serverId: 为在maven setting.xml配置的server信息id--> <serverId>nexus-docker-registry</serverId> <registryUrl>192.168.129.160:5000</registryUrl> <!-- 打上tag的新镜像 push 到nexus--> <imageName>192.168.129.160:5000/${project.artifactId}</imageName> </configuration>

将上文打上tag标签的镜像，推送到私服nexus：mvn clean docker:push -Dmaven.test.skip=true -DskipDockerBuild -DskipDockerTag

3.6 docker插件参数

-DskipDockerBuild to skip image build-DskipDockerTag to skip image tag-DskipDockerPush to skip image push-DskipDockerto skip any Docker goals

3.7 绑定命令到maven phases

<executions> <execution> <id>build-image</id> <phase>package</phase> <goals> <goal>build</goal> </goals> </execution> <execution> <id>tag-image</id> <phase>package</phase> <goals> <goal>tag</goal> </goals> <configuration> <image>jhs/${project.artifactId}:${project.version}</image> <newName>192.168.129.160:5000/${project.artifactId}:${project.version}</newName> </configuration> </execution> <execution> <id>push-image</id> <phase>deploy</phase> <goals> <goal>push</goal> </goals> <configuration> <!-- docker push 推送到远程镜像仓库--> <!-- serverId: 为在maven setting.xml配置的server信息id--> <serverId>nexus-docker-registry</serverId> <registryUrl>192.168.129.160:5000</registryUrl> <imageName>192.168.129.160:5000/${project.artifactId}</imageName> </configuration> </execution> </executions>

3.8 最佳实践

<properties> <docker.host>http://192.168.129.162:2375</docker.host> <docker.registry.url>192.168.129.160:5000</docker.registry.url> </properties> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>1.0.0</version> <configuration> <imageName>dic/${project.artifactId}:${project.version}</imageName> <!--添加额外的指定标签（可配置多个）, 若果没做指定，则为latest--> <!-- <imageTags> <imageTag>${project.version}</imageTag> </imageTags> --> <!-- 指定 Dockerfile 路径 ：项目根路径下--> <dockerDirectory>${project.basedir}/docker</dockerDirectory> <!--指定远程 docker api地址--> <dockerHost>${docker.host}</dockerHost> <!-- copy资源 --> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> <!--docker build dockerfile时：设置镜像创建时的变量 --> <buildArgs> <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE> </buildArgs> </configuration> <executions> <execution> <id>build-image</id> <phase>package</phase> <goals> <goal>build</goal> </goals> </execution> <execution> <id>tag-image</id> <phase>package</phase> <goals> <goal>tag</goal> </goals> <configuration> <image>dic/${project.artifactId}:${project.version}</image> <newName>${docker.registry.url}/${project.artifactId}:${project.version}</newName> </configuration> </execution> <execution> <id>push-image</id> <phase>deploy</phase> <goals> <goal>push</goal> </goals> <configuration> <!-- docker push 推送到远程镜像仓库--> <!-- serverId: 为在maven setting.xml配置的server信息id--> <serverId>nexus-docker-registry</serverId> <registryUrl>${docker.registry.url}</registryUrl> <imageName>${docker.registry.url}/${project.artifactId}</imageName> </configuration> </execution> </executions> </plugin> </plugins> </build>
