Installing java in Docker image

Question

This is my very first try to create a docker image and I\'m hoping someone can help me out. My Dockerfile looks roughly like this:

FROM mybaseimage:0.1
MAINT         


        

Answer 1

I was able to install Java-11 on an image using Ubuntu 18.04. I also just needed it for only one application. (The Python wrapper around Apache Tika.)

FROM python:3.8.2-buster
COPY . /usr/src/app

# Install OpenJDK-11
RUN apt-get update && \
    apt-get install -y openjdk-11-jre-headless && \
    apt-get clean;

# Install PYTHON requirements
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

# START WEBAPP SERVICE
CMD [ "python", "/usr/src/app/main.py" ]

Hope that helps.
