Install python 3.9 on an amazon/aws-cli docker image-CodePudding

How do I install a Python 3.9 on top of amazon/aws-cli docker image which by default comes with python 2.7? What I have tried so far are these series of commands based off installation tutorials for installing Python 3 on Amazon Linux 2:

FROM amazon/aws-cli:latest

WORKDIR ./

COPY ./.aws ./root/.aws

COPY . .

RUN yum install gcc openssl-devel bzip2-devel libffi-devel -y
RUN yum install wget tar -y
RUN cd /opt
RUN wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz
RUN tar xzf Python-3.9.6.tgz
RUN cd Python-3.9.6
RUN ./configure --enable-optimizations
RUN make altinstall
RUN rm -f /opt/Python-3.9.6.tgz

RUN ["python3", "-u", "app.py"]

But I am receiving this error:

CodePudding user response：

You have to install gzip and make as well and use WORKDIR:

FROM amazon/aws-cli:latest

WORKDIR ./

COPY ./.aws ./root/.aws

COPY . .

RUN yum install gcc openssl-devel bzip2-devel libffi-devel gzip make -y
RUN yum install wget tar -y
WORKDIR /opt
RUN wget https://www.python.org/ftp/python/3.9.6/Python-3.9.6.tgz
RUN tar xzf Python-3.9.6.tgz
WORKDIR /opt/Python-3.9.6
RUN ./configure --enable-optimizations
RUN make altinstall
RUN rm -f /opt/Python-3.9.6.tgz

RUN ["python3", "-u", "app.py"]
