Question

I have problem, my dockerfile, cant install openjdk-11-jdk, before my script is doing well, but when I want to run again, its problem, my script on dockerfile:

FROM python:3.7

RUN pip install --upgrade pip

RUN apt-get update && \
    apt-get install -y \
        openjdk-11-jdk


ENV JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/
ENV PATH=$PATH:$JAVA_HOME/bin

Thank you

Dockerfile can doing well to run my apps

Answer 1

Now you have to change the FROM instruction since the default image for python:3.7 is bookworm and openjdk-11-jdk is available on bullseye:

FROM python:3.7-bullseye

RUN pip install --upgrade pip

RUN apt-get update && \
    apt-get install -y \
        openjdk-11-jdk


ENV JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/
ENV PATH=$PATH:$JAVA_HOME/bin

Or for a lightweight image, use python:3.7-slim-bullseye.
