4.docker-maven-plugin

在前两篇文章2.Docker-resigtry2和3.SpringCloud-Eureka-Docker基础上进行配置。

例子使用com.spotify的maven插件，后续会对比研究io.fabric3的maven插件。

1.将插件配置到pom文件中

1.1 定义变量

配置hosts文件，加入59.110.14.120 docker.registry.server

docker.registry.server:5000

1.2 配置插件

com.spotify

docker-maven-plugin

3.7.0





docker.registry.server



${docker.registry.server}/${project.artifactId}











openjdk:8u131-jdk-alpine

["java", "-jar", "/${project.build.finalName}.jar"]





/

${project.build.directory}

${project.build.finalName}.jar













build-image

package



build







tag-image

package



tag





${docker.registry.server}/${project.artifactId}

${docker.registry.server}/${project.artifactId}

1.3 setting.xml配置

docker.registry.server

gaojingyuan

testpwd

2.打包并推送image

mvn clean package -DpushImage

3. 服务器下载并启动服务

登录私服

docker login docker.registry.server:5000

下载镜像

docker pull docker.registry.server:5000/eurekaserverdocker

启动服务

docker stack deploy -c docker-compose.yml eurekaserverdocker

停止服务

docker stack rm eurekaserverdocker

常见错误：

1.执行mvn clean package -DpushImage5次retry后报错：

Failed to push docker.registry.server:5000/eurekaserverdocker, retrying in 10 seconds (5/5).

com.spotify.docker.client.exceptions.DockerException: no basic auth credentials

解决方法：

需要配置 vim .docker/config.json

把"docker.registry.server:5000": {},改为"https://docker.registry.server:5000": {},

"auths": {

"https://docker.registry.server:5000": {},

"https://index.docker.io/v1/": {}

},

2.执行mvn clean package -DpushImage报错：

Failed to execute goal com.spotify:docker-maven-plugin:1.0.0:tag (tag-image) on project eurekaserverdocker: Exception caught: Image not found: eurekaserverdocker: Request error: POST unix://localhost:80/images/eurekaserverdocker/tag?repo=docker.registry.server%3A5000%2Feurekaserverdocker: 404, body: {"message":"No such image: eurekaserverdocker:latest"}: HTTP 404 Not Found -> [Help 1]

解决方法：

需要正确配置和

tag-image

package



tag





${docker.registry.server}/${project.artifactId}

${docker.registry.server}/${project.artifactId}
