Create test hub deployment for D-Lab!

[balajialg]

Summary

@aculich is interested in the idea of blue-green deployment for D-Lab. He intends to use the D-Lab test hub for testing bleeding edge changes (by customizing images regularly) and the standard hub for running workshops. You can read more about his requirements here.

Are there ways to solve this requirement without creating new hubs? If not, can we create a new hub with URL dlab-testing.datahub.berkeley.edu which has its own staging and prod with admin rights for @aculich and their team so that they can customize their image as per their interests. We can have the node pools and filestores shared with the D-Lab hub inorder to optimize for cloud costs (Thanks @ryanlovett for the suggestion).

User Stories

• As a D-Lab Hub admin I want to test bleeding edge changes in a new hub so that the existing D-Lab deployment remains the stable hub which is not affected.

Acceptance Criteria

• As a D-Lab admin, I can test bleeding edge changes in a test hub dedicated to D-Lab admins.

Important information

Most of the github repos that D-Lab uses come from one place: https://github.com/dlab-berkeley/
Which are the github repos that the upcoming workshop list points to.

Tasks to complete

• Evaluate whether there is a non hub approach to solve this requirement
• If not, Create a new hub
• Provide enough privileges for Aaron and team to customize the image
