idea集成docker实现远程部署

一、使用步骤

1.设置docker.service配置文件

vim /lib/systemd/system/docker.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
ExecStart=/usr/bin/dockerd -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

2.重新加载配置文件并重启docker

systemctl daemon-reload && systemctl restart docker

3.下载docker插件

4.配置idea的docker远程连接

5.配置pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.3</version>
        <relativePath/> <!-- lookup parent from repository -->

    <name>docker</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
        <docker.image.prefix>docker</docker.image.prefix>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>

            <scope>test</scope>
        </dependency>
    </dependencies>

    <!--打jar包插件-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                    <addResources>true</addResources>
                    <!--主启动类-->
                    <mainClass>com.example.docker.DockerApplication</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>



            <plugin>
                <!--安装docker插件-->
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <!--远程连接地址-->
                    <dockerHost>http://ip地址:2375</dockerHost>
                    <!--镜像名称-->
                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                    <!--dockerfile的位置-->
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <!--jar 包所在的路径 此处配置的 即对应 target 目录-->
                            <directory>${project.build.directory}</directory>
                            <!-- 需要包含的 jar包 ，这里对应的是 Dockerfile中添加的文件名　-->
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

6.编写dockerfile

FROM java:8
COPY *.jar /app.jar
CMD ["--server.port=8080"]
EXPOSE 8080
ENTRYPOINT ["java","-jar","app.jar"]

6.打包镜像并上传

7.部署容器

总结

服务器docker要开放2375端口，使用阿里云或腾讯云要设置防火墙过滤规则。
