SpringBoot应用部署到Docker上(docker-ce版本)

配置TCP远程连接(docker-maven-plugin插件连接的地址)

# 加上红色标识的部分
[root@localhost admin]# vim /lib/systemd/system/docker.service [Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com BindsTo=containerd.service After=network-online.target firewalld.service containerd.service Wants=network-online.target Requires=docker.socket [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 unix:///var/run/docker.sock -H tcp://0.0.0.0:2375 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.

开放2375端口

# 开启防火墙端口
firewall-cmd --zone=public --add-port=2375/tcp --permanent
systemctl restart firewalld

配置私有仓库

配置daemon.json文件

[root@localhost admin]# vim /etc/docker/daemon.json

{
  "insecure-registries":["192.168.192.128:443"]
}

# 重启服务
systemctl daemon-reload
systemctl restart docker

然后下载registry镜像

[root@localhost admin]# docker pull registry
[root@localhost admin]# mkdir /usr/docker_registry_data
[root@localhost admin]# docker run -d -p 443:5000 -v /usr/docker_registry_data:/var/lib/registry registry

# 开启防火墙端口
firewall-cmd --zone=public --add-port=443/tcp --permanent
systemctl restart firewalld

新建SpringBoot工程

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.2.0</version>
                <configuration>
                    <!--Docker要求推送的映像名称以仓库的主机名和端口为前缀。例如,要推送my-image到registry.example.com,镜像需要标记为registry.example.com/my-image-->
                    <imageName>192.168.192.128:443/hello</imageName>
                    <!--基础镜像-->
                    <baseImage>java</baseImage>
                    <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
                    <!-- copy the service's jar file from target into the root directory of the image -->
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <forceTags>true</forceTags>
                    <imageTags>
                        <imageTag>latest</imageTag>
                    </imageTags>
                </configuration>
            </plugin>
        </plugins>
    </build>

打包(注意,要保证服务器的Registry容器开启)

SET DOCKER_HOST=tcp://192.168.192.128:2375
mvn clean package -Dmaven.test.skip=true docker:build -DpushImageTag

 

 成功

 

 现在回来看镜像

 

启动(后台启动加上-d)

 

 访问

 

另一种方式:Dockerfile

在src/main下新建一个docker目录

 Dockerfile内容

# 基础镜像
FROM java:8
# 打包jar去向
ADD /hello-0.0.1-SNAPSHOT.jar /app.jar
# 暴露端口
EXPOSE 8081
# 启动命令
ENTRYPOINT ["java", "-jar", "/app.jar"]

pom文件修改如下:

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.2.0</version>
                <configuration>
                    <!--Docker要求推送的映像名称以注册表的主机名和端口为前缀。例如,要推送my-image到registry.example.com,镜像需要标记为registry.example.com/my-image-->
                    <imageName>192.168.192.128:443/hello-2</imageName>
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                    <forceTags>true</forceTags>
                    <imageTags>
                        <imageTag>latest</imageTag>
                    </imageTags>
                </configuration>
            </plugin>
        </plugins>
    </build>

打包推送

SET DOCKER_HOST=tcp://192.168.192.128:2375
mvn clean package -Dmaven.test.skip=true docker:build -DpushImageTag

运行结果

 

 查看镜像
