Question

在下面的docker文件中：

FROM alpine:latest

ENV HOME /home/samcli
ENV PATH $HOME/.local/bin:$PATH

RUN mkdir /root/bin /aws; \
    apk add --no-cache groff less bash python jq curl py-pip tzdata

RUN ln -fs /usr/share/zoneinfo/Etc/UTC /etc/localtime

RUN apk add --no-cache --virtual .build-deps gcc python2-dev python3-dev linux-headers musl-dev && \
    pip install --upgrade pip; \
    adduser samcli -Du 5566; \
    chown -R samcli $HOME;

USER samcli

WORKDIR $HOME

RUN pip install --user --upgrade awscli aws-sam-cli;

USER root

RUN apk del .build-deps; \
    rm -rf /var/cache/apk/*

图层（RUN pip install --user --upgrade awscli aws-sam-cli;）与python 2.7一起安装，尽管映像已安装python3.7。

我在安装python软件包时看到以下弃用错误：

Step 9/11 : RUN pip install --user --upgrade awscli aws-sam-cli;

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/

如何使用python3.7安装AWS软件包？因为下面的命令正在使用python2

pip install --user --upgrade awscli aws-sam-cli;

我建议您使用基于alpine的python官方映像，因此您无需维护和安装python版本。基本图片下方是基于alpine 3.9和python version is 3.7

FROM python:3.7-alpine3.9

ENV HOME /home/samcli
ENV PATH $HOME/.local/bin:$PATH
RUN ln -fs /usr/share/zoneinfo/Etc/UTC /etc/localtime
RUN apk add --no-cache --virtual .build-deps python2-dev  python3-dev gcc linux-headers musl-dev && \
    adduser samcli -Du 5566; \
    chown -R samcli $HOME;
RUN apk add --no-cache groff less bash jq curl py-pip tzdata
USER samcli

WORKDIR $HOME

RUN pip install --user --upgrade awscli aws-sam-cli;
USER root

RUN apk del .build-deps; \
    rm -rf /var/cache/apk/*

通过python3.7版本pws安装aws-sam-cli软件包
