I am trying to install the java runtime in a Debian based docker image (mcr.microsoft.com/dotnet/core/sdk:3.1-buster). According to various howtos this should be possible by running
RUN apt update
RUN apt-get install openjdk-11-jre
The latter command comes back with
E: Unable to locate package openjdk-11-jre
However according to https://packages.debian.org/buster/openjdk-11-jre the package does exist. What am I doing wrong?
Unsure from which image your are pulling. I used slim, Dockerfile.
from debian:buster-slim
ENV DEBIAN_FRONTEND=noninteractive
RUN mkdir -p /usr/share/man/man1 /usr/share/man/man2
RUN apt-get update && \
apt-get install -y --no-install-recommends \
openjdk-11-jre
# Prints installed java version, just for checking
RUN java --version
NOTE: If you don't run the mkdir -p /usr/share/man/man1 /usr/share/man/man2 you'll run into dependency problems with ca-certificates, openjdk-11-jre-headless etc. I've been using this fix provided by community, haven't really checked the permanent fix.
