java-k8s Dockerfile using legacy Debian Jessie backports

[archelangelo]

I was following the Deploy A Java Application On Kubernetes With Helm tutorial and encountered the following error message when running docker build build-app -t jhipster

Step 3/6 : RUN echo "deb http://http.debian.net/debian jessie-backports main" >> /etc/apt/sources.list &&     install_packages ca-certificates-java/jessie-backports openjdk-8-jdk-headless bzip2

It seems that the jessie-backports source was recently removed. I then tried using http://archive.debian.org/debian as the source but got this error:

Step 3/6 : RUN echo "deb http://archive.debian.org/debian jessie-backports main" >> /etc/apt/sources.list &&     install_packages ca-certificates-java/jessie-backports openjdk-8-jdk-headless bzip2

I also tried using newer stretch-backports but got this error:

So I guess there some related changes that need to be made.

Hi, @archelangelo.

Thank you for reporting this. I've created an internal task to update the tutorial. I can't give you an ETA, but I'll come back to you when it's done.

In the meantime, you may try using the minideb-extras:stretch image instead of the jessie one, and installing the packages from the stretch repos:

FROM bitnami/minideb-extras:stretch-r386

RUN install_packages ca-certificates-java openjdk-8-jdk-headless bzip2

Regards,
Alejandro
