如何将AWS Docker映像用于Spring Boot项目

标签： spring amazon-web-services docker spring-boot aws-cli

我有一个可以完美地在docker上运行的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，因为我已经安装了 AWS SDK >在我的计算机上为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，出现此异常：

看起来像docker不能识别 AWS凭据，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，但是我不知道该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

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通过AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY这套凭据对AWS进行了身份验证。您可能会在~/.aws/credentials文件中列出如下的键值：

[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
