java - Dockerized Spring Boot 无法在 Raspberry Hyperiot OS + Gitlab CI + Spring Boot 上运行

Question

我想使用 Gitlab CI 和 Docker 为我的 Spring Boot 项目设置自动部署。为此，我在树莓派上安装了 Hypriot OS 来运行我的 docker 容器。 Maven 和 Docker 构建通过 Gitlab CI 运行没有错误。但如果我在 Raspberry 上运行 docker，什么也不会发生。

gitlab-ci.yml

image: docker:latest

services:
    - docker:dind

variables:
    DOCKER_DRIVER: overlay
    SPRING_PROFILES_ACTIVE: gitlab-ci
    USER_GITLAB: ft
    APP_NAME: ft-backend
    REPO: backend

stages: 
    - build
    - docker

maven-build:
    image: maven:3-jdk-8
    stage: build
    script: "mvn package -B"
    artifacts:
        paths:  
            - target/*.jar

docker-build:
    stage: docker
    script:
        - docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.gitlab.com
        - docker build -t registry.gitlab.com/ft/$REPO . 
        - docker push registry.gitlab.com/ft/$REPO

应用程序属性

spring.profiles.active=local
server.port=8080
spring.application.name=backend

Dockerfile

FROM jsurf/rpi-java:latest
VOLUME /tmp
ADD target/ft-backend-0.0.1-SNAPSHOT.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"]
CMD [""]

我在 Raspberry 上使用以下命令来启动 Docker。但如果我想在 192...:8080 上访问我的 Raspberry，我的项目不会出现。 docker ps 也不显示任何内容。

docker login registry.gitlab.com
docker pull registry.gitlab.com/ft/backend
docker run -d -p 8080:8080 registry.gitlab.com/ft/backend:latest

Answer 1

要构建 Spring Boot maven 项目的 docker 镜像，我建议使用 dockerfile-maven-plugin .

1.配置将项目打包为可执行jar

<build>
  <plugins>
    <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>
  ...

2.配置构建 Docker 镜像

  ...
    <plugin>
      <groupId>com.spotify</groupId>
      <artifactId>dockerfile-maven-plugin</artifactId>
      <version>${dockerfile-maven-plugin.version}</version>
      <executions>
        <execution>
          <id>default</id>
          <goals>
            <goal>build</goal>
            <goal>push</goal>
          </goals>
        </execution>
      </executions>
      <configuration>
        <repository>${docker.repository}/${project.artifactId}</repository>
        <tag>${project.version}</tag>
        <buildArgs>
          <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
        </buildArgs>
      </configuration>
    </plugin>

3.创建 Dockerfile

4.构建 Docker 镜像

$ mvn clean package
