如何將AWS Docker映像用於Spring Boot項目

Question

我有一個可以在docker上正常運行的spring boot項目，現在我在項目中添加了一些功能，可以將文件上傳和刪除到s3，並且在本地運行得很好，因為我已經在計算機上安裝了適用於Java的AWS開發工具包 。 現在我想為我的項目創建一個docker映像，但是當我運行它時，出現此異常：

看起來docker無法識別AWS憑證 ，我決定下載安裝了AWS CLI的docker容器：

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

我在Docker上運行了這個容器，我配置了憑據並運行良好，現在我想將所有這些片段集成到我的Dockerfile中，但是我不知道我必須在哪里配置使用這個新容器將文件上傳和刪除到S3 。

在我的項目中，我已經配置了AWS依賴項。

這是我的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

該應用程序在本地運行良好，但在容器中運行失敗，可能是因為您的本地計算機已通過以下一組憑證通過AWS進行身份驗證： AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY 。 您可能會在~/.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

您可以將這些值作為環境變量傳遞到容器，這將允許AWS開發工具包在訪問S3時使用它們。 Docker命令示例：

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