如何将AWS Docker映像用于Spring Boot项目

Question

我有一个可以在docker上正常运行的spring boot项目，现在我在项目中添加了一些功能，可以将文件上传和删除到s3，并且在本地运行得很好，因为我已经在计算机上安装了适用于Java的AWS开发工具包 。 现在我想为我的项目创建一个docker映像，但是当我运行它时，出现此异常：

看起来docker无法识别AWS凭证 ，我决定下载安装了AWS CLI的docker容器：

https://hub.docker.com/r/garland/aws-cli-docker/

我在Docker上运行了这个容器，我配置了凭据并运行良好，现在我想将所有这些片段集成到我的Dockerfile中，但是我不知道我必须在哪里配置使用这个新容器将文件上传和删除到S3 。

在我的项目中，我已经配置了AWS依赖项。

这是我的Dockerfile ：

FROM openjdk:8-jre-alpine

ENV SPRING_OUTPUT_ANSI_ENABLED=ALWAYS \
    JHIPSTER_SLEEP=0 \
    JAVA_OPTS=""

# Add a jhipster user to run our application so that it doesn't need to run as root
RUN adduser -D -s /bin/sh jhipster
WORKDIR /home/jhipster

ADD entrypoint.sh entrypoint.sh
RUN chmod 755 entrypoint.sh && chown jhipster:jhipster entrypoint.sh
USER jhipster

ADD *.war app.war

ENTRYPOINT ["./entrypoint.sh"]

EXPOSE 2020

Answer 1

该应用程序在本地运行良好，但在容器中运行失败，可能是因为您的本地计算机已通过以下一组凭证通过AWS进行身份验证： AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY 。 您可能会在~/.aws/credentials文件中列出~/.aws/credentials ，如下所示：

[default]
AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

您可以将这些值作为环境变量传递到容器，这将允许AWS开发工具包在访问S3时使用它们。 Docker命令示例：

docker run -e "AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE" -e "AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" my-image:latest
