    • Added filtering for sites, course_ids, and users
    • Added html template from: django-admin-list-filter-dropdown
  • Fixed pipeline bugs - active users date->datetime bug

Known Issues

  • The "Number of registered learners" on the site metrics page currently shows all the users registered in the site, not just the learners.

Virtual Software Labs

Improvements and Bug Fixes

  • Logging/reporting refactor (V4.19.0)
    • We reworked the logging infrastructure to provide more fine-grained detail about container start and stop time. This release also sets the foundation for more enhanced reporting in the future. Access this report by navigating to yourAVLdomain.com/reporting/raw_history/csv. This is the “quick and dirty” version of what will become a full reporting dashboard in the future.
  • Enable the deletion of images not associated with an event (V4.19.0)
    • This pesky bug would prohibit the user from deleting an event, even though the UI reported that all the event’s containers had been deleted.
  • Increase max number of pings (V4.19.0)
    • After a container is started, we send an HTTP request to your “primary port.” This way, we ensure that not only that the student’s lab is started, but also that your software is running in the lab. v4.19 increases the max number of ping from 9 to 12; change this in your image settings if needed.
  • Fix container extension datepicker (V4.19.0)
    • The datepicker for expanding the expiration date of one lab now responds correctly. Previously, the date format suggested would not in fact pass validation on the backend.
  • Use custom nginx 502 page (V4.19.0)
    • You can provide us with a custom 502.html page to show the user, should a container fail to launch. 
  • Fixed CORS headers for custom domains and nested Appsembler subdomains (V4.18.5)
    • Fixes issue where student container would not launch or reset and the student would not get a message back.
    • This only applies to customers who have custom domains on Tahoe.
  • Added a GDPR notice on event dashboard (V4.18.3)
    • Adds a notice to the learner dashboard with a privacy policy link that's configurable per cluster. The notice is shown if the feature flag is enabled in django admin.
  • Auto-generate Let's Encrypt SSL certs (V4.18.0)
    • This adds a certbot role that generates let’s encrypt certs and runs a cron to have them renewed. It first checks to see if a cert exists in a specified path, if not it generates it automatically.
    • The implementation leverages certbot client and certbot-dns-goodle to generate certs that are valid for 90 days. Then a cron job is scheduled to run daily and execute the renew command. A certificate will be due for renewal if it expires in less than 30 days. (improvement to Let’s Encrypt integration) - open source way to do SSL certs
  • Moved database backups to GCloud (V4.18.0)
    • This configures storage backups on google cloud buckets. Currently, backups are being stored in S3 storage buckets.
  • Upgraded Postgres to v10  V4.18.0)
  • Increased uWSGI buffer size (V4.18.0)
