如何在spring boot项目中使用aws docker镜像

Question

我有一个在 docker 上完美运行的 spring boot 项目，现在我在我的项目中添加了一些功能，用于将文件上传和删除到 s3，并且在本地它运行良好，因为我已经安装了 AWS SDK 对于我电脑上的 java。现在我想为我的项目创建一个 docker 映像，但是当我运行它时，我得到了这个异常：

看起来 docker 无法识别 AWS 凭证，我决定下载一个安装了 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，我配置了凭据并且运行良好，现在我想将所有这些部分集成到我的 Dockerfile 但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

应用程序在本地运行良好，但在容器中失败，可能是因为您的本地计算机使用一组凭据通过 AWS 的身份验证：AWS_ACCESS_KEY_ID 和 AWS_SECRET_ACCESS_KEY。 ~/.aws/credentials 文件中的键值可能如下所示：

[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给容器，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
