Google Appengine Ruby Docker image is grossly outdated #178

Closed romanrev closed 5 years ago

romanrev commented 5 years ago

Hello,

The Google built Docker image for Google Appengine Flexible runtime is grossly outdated: the latest image was built on 3 May 2018, almost a year ago:

https://console.cloud.google.com/gcr/images/google-appengine/GLOBAL/ruby?gcrImageListsize=30

The issue with this image is that it relies on the jessy Debian release which support has now reached end of life: https://lists.debian.org/debian-devel-announce/2019/03/msg00006.html and any image built on top of that image (FROM gcr.io/google-appengine/ruby:latest), will yield this error:

Failed to fetch http://httpredir.debian.org/debian/dists/jessie-updates/InRelease Unable to find expected entry 'main/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)

The image you reference is actually not the image currently used by the App Engine flexible runtime. (It's an older image that was used by the runtime until about a year ago, as you mention. The current image is built on Ubuntu.)

@dazuma thanks for your comment, could you explain why the latest image I see at https://console.cloud.google.com/gcr/images/google-appengine/GLOBAL/ruby?gcrImageListsize=30 is from 2018 then? Are you able to point me to the correct Google public GCR repository with the latest Ruby flexible runtime Docker image please?

Again, those images were used by old versions of the Ruby flexible runtime, but are not used by the current runtime. The current runtime images are under https://console.cloud.google.com/gcr/images/gcp-runtimes/GLOBAL/ruby

You generally should not need to use these docker images directly. They are intended to be "internal" to the runtime: ruby setup for App Engine. If you want to create a "custom" runtime for a Ruby app, I recommend just using the standard ruby image from DockerHub as a base image.
