Spring Cloud Config Server 不适用于 Docker 构建

Question

您好，感谢您的关注！我在尝试使用 Git 对 Spring Cloud Config Server 进行 Dockerize 来管理我的微服务时遇到了问题。当它只是 Spring Cloud 微服务上下文时，我的应用程序工作正常，但是当我为此配置服务器创建 Dockerfile 并构建它时，我得到了下一个错误：

    java.lang.IllegalStateException: Failed to load ApplicationContext

但是我的 bootstrap.yml 中有一个 gitRepo，当我在没有 Dockerfile 的情况下使用它时它可以工作：

spring:
  application:
    name: CONFIG-SERVER
  profiles:
    active:
    - git
  cloud:
    config:
      server:
        git:
          default-label: main
          uri: https://github.com/hideyourname/cloud-config-server.git

Soo...我认为我创建 Dockerfile 的方式存在问题，因为即使存在我的 git 也可以找到它

FROM openjdk:11 as BUILDER

LABEL maintainer = "petrea config server"

#EXPOSE 8080 SA VEDE MDACA MERGE

COPY /target/boys-config.jar boys-config.jar

RUN mkdir -p target/dependency && (cd target/dependency; jar -xf /boys-config.jar)


#Stage 2
FROM openjdk:11-slim
VOLUME /tmp

ARG DEPENDENCY=/target/dependency

COPY --from=BUILDER ${DEPENDENCY}/BOOT-INF/lib /boys-config/lib
COPY --from=BUILDER ${DEPENDENCY}/META-INF /boys-config/META-INF
COPY --from=BUILDER ${DEPENDENCY}/BOOT-INF/classes /boys-config

#execute the application
ENTRYPOINT ["java", "-cp", "boys-config:boys-config/lib/*", "com.petrea.boys-config-server.BoysConfigServerApplication"]

我在 POM 中有 Cloud Config Server 依赖项，在我的主类中有 @EnableConfigServer，但由于某种原因，当我使用 Dockerfile 构建此映像时，它失败了……请问有什么想法吗？

如果您按照上面引用的书中的示例进行操作，我建议您将下面的 sn-p 从 bootsrap.yml 移动到 applications.yml。

spring:
  application:
    name: CONFIG-SERVER
  profiles:
    active:
    - git
  cloud:
    config:
      server:
        git:
          default-label: main
          uri: https://github.com/hideyourname/cloud-config-server.git

这就是我所做的，它对我有用。
