Docker 圖像無法讀取 Spring 引導應用程序上的 application.yml 文件

Question

我目前正在嘗試對具有 2 個配置文件的 spring 啟動應用程序進行 docker 化：

application-dev.yml和application-prod.yml

當我在我的機器上運行該應用程序時它可以工作，但是當我嘗試 dockerize 時，它無法從所述文件中讀取。 它不會將變量加載到@Value 注釋中，即使服務端口是錯誤的。

這是我的 dockerfile：

FROM maven:3-jdk-11 AS builder
RUN mkdir -p /usr/local/backend
RUN chmod 777 /usr/local/backend/
ADD settings.xml /root/.m2/
COPY settings.xml /usr/share/maven/ref/
COPY pom.xml /usr/share/maven/ref/repository
COPY . /usr/local/backend
WORKDIR /usr/local/backend
RUN mvn clean generate-sources package
FROM openjdk:11
COPY --from=builder /usr/local/backend/target/service-userinfosearch.jar /usr/local/backend/
RUN chmod 777 /usr/local/backend/
WORKDIR /usr/local/backend
ENTRYPOINT ["java", "-jar", "service-userinfosearch.jar","-Dspring.profiles.active=dev"]

我正在使用此命令進行構建：

docker build . -t userinfosearch/v1

並運行這個：

docker run --rm --name version1 -p 8082:8082 userinfosearch/v1

Answer 1

永不言敗，已解決。

將以下內容添加到運行命令中即可：

-e "SPRING_PROFILES_ACTIVE=dev"
