SpringCloud项目打包Docker镜像并发布到Harbor仓库

1. Docker-compose安装
2. Harbor仓库搭建
3. Docker环境配置
4. 项目配置

1. Docker-compose安装

#安装
wget http://rancher-mirror.cnrancher.com/docker-compose/v1.27.4/docker-compose-Linux-x86_64
mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose
#赋权
chmod a+x /usr/local/bin/docker-compose
#查看版本号
docker-compose --version

2. Harbor仓库搭建

Harbor安装前务必先安装好Docker-compose。
Harbor的安装包有offline和online两种，可视网络情况选择，此处选用offline安装。

手动下载好离线包并上传到服务器进行安装

tar zxvf harbor-offline-installer-v2.5.2.tgz

修改配置

#修改配置
cp harbor.yml.tmpl harbor.yml
vim harbor.yml

关键配置

#配置主机ip及端口
hostname: 8.142.11.11
http:port: 8099
#屏蔽https
#https:# port: 443#certificate: /your/certificate/path#private_key: /your/private/key/path
#管理员默认密码
harbor_admin_password: Harbor12345

安装

./install.sh

安装完成后可使用http://8.142.11.11:8099进行访问，账号admin/Harbor12345。

视需要创建用户及项目

3. Docker环境配置

将私有仓库地址添加到docker配置 /etc/docker/daemon.json中

{"registry-mirrors": ["https://registry.docker-cn.com"],"insecure-registries":["8.142.11.11:8099"],"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"storage-driver": "overlay2"
}

修改完成后重新加载配置并重启docker

systemctl daemon-reload
systemctl restart docker

使用docker登录harbor

docker login http://8.142.11.11:8099 --username harbor --password harbor

登录成功后docker会将账号密码以base64形式存放到/root/.docker/config.json中

WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

测试镜像推送

#标记镜像tag
docker tag registry 8.142.11.11:8099/leway-cloud/registry:latest
#推送镜像
docker push 8.142.11.11:8099/leway-cloud/registry:latest
#推送完成
The push refers to repository [8.142.11.11:8099/leway-cloud/registry]
a1d94f4a4c89: Pushed
1d80677cd085: Pushed
58548fced558: Pushed
79f02b258438: Pushed
24302eb7d908: Pushed

推送完成后可以在仓库中查看

4. 项目配置

在父级pom.xml中使用dockerfile-maven-plugin插件

 <properties><dockerfile.maven.plugin.version>1.4.13</dockerfile.maven.plugin.version><docker.repository>8.142.11.11:8099</docker.repository><docker.repository.project>leway-cloud</docker.repository.project><!--默认全局跳过dockerfile--><dockerfile.skip>true</dockerfile.skip></properties><build><plugins><plugin><groupId>com.spotify</groupId><artifactId>dockerfile-maven-plugin</artifactId><version>${dockerfile.maven.plugin.version}</version><!--不需打包推送镜像到仓库时将此处executions屏蔽即可--><executions><execution><id>default</id><goals><goal>build</goal><goal>push</goal></goals></execution></executions><configuration><repository>${docker.repository}/${docker.repository.project}/${docker.image.name}</repository><tag>${project.version}</tag><buildArgs><JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE></buildArgs><!--使用maven的setting.xml文件中harbor的登录信息-->                <useMavenSettingsForAuth>true</useMavenSettingsForAuth></configuration></plugin></plugins></build>

在Maven的配置文件settings.xml中配置harbor登录信息

 <servers><server><id>8.142.11.11:8099</id><username>harbor</username><password>harbor</password><configuration><email>liuwei.cd@mapgis.com</email></configuration></server></servers>

需要打包成镜像的子模块中配置pom.xml

    <properties><docker.image.name>${artifactId}</docker.image.name><dockerfile.skip>false</dockerfile.skip></properties>

同时在子模块添加Dockerfile文件

#指定所需依赖的基础镜像
FROM openjdk:8-jdk-alpine
#维护者
MAINTAINER leway
ARG JAR_FILE
#设置环境变量
ENV TIME_ZONE=Asia/Shanghai
ENV LANG=C.UTF-8
#在容器构建过程中执行的命令
RUN echo "https://mirrors.aliyun.com/alpine/v3.6/main" > /etc/apk/repositories \&& echo "https://mirrors.aliyun.com/alpine/v3.6/community" >> /etc/apk/repositories \#以上两行指定alpine(Linux)源#升级包&& apk update upgrade \#安装常用命令&& apk add --no-cache procps unzip curl bash tzdata \#安装宋体&& apk add ttf-dejavu \#同步时区&& ln -snf /usr/share/zoneinfo/${TIME_ZONE} /etc/localtime  \&& echo ${TIME_ZONE} > /etc/timezone
#声明服务运行的端口
EXPOSE 8003
#将当前目录下的jar包复制到docker容器的/目录下
ADD ${JAR_FILE} /app.jar
#指定docker容器启动时执行的命令
ENTRYPOINT ["java","-jar","-Duser.timezone=Asia/Shanghai","/app.jar"]

Docker开启远程

vim /usr/lib/systemd/system/docker.service

修改ExecStart内容

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

重启docker

systemctl daemon-reload
systemctl restart docker

DOCKER_HOST配置
插件默认使用本地docker环境，因此使用远程docker时需要配置环境变量
DOCKER_HOST=tcp://8.142.11.11:2375

打包及推送

至此配置完成，使用 mvn package或mvn dockfile:build可打包镜像文件。打包镜像时会按照Dockerfile中的指令顺序执行。
