MozMEAO SRE Status Report - November 7, 2017

07 Nov 2017, by Dave Parfitt

Here’s what happened on the MozMEAO SRE team from October 31st - November 7th.

Current work

SUMO

Work progresses on a SUMO development environment for use with Kubernetes in AWS.

• S3 and Cloudfront distributions have been provisioned, and DNS has been setup for the following domains:
  • https://dev-cdn.sumo.mozilla.net/
  • https://stage-cdn.sumo.mozilla.net/
  • https://prod-cdn.sumo.mozilla.net/
• We decided to use a small elastic.co-hosted Elasticsearch instance instead of using the Helm chart due to difficulties getting the chart to run.
• The team has decided use MySQL or MariaDB instead of pursuing a migration to Postgres before moving to AWS.

MDN

• The October 2017 Kuma Report describes the MDN move to AWS.
• The mdn-samples.mozilla.org domain is in the process of being moved to Kubernetes.
  • See also https://bugzilla.mozilla.org/show_bug.cgi?id=1414294
• We’re now varying the CloudFront cache on the querystring parameter revision, which is used to refresh embeded live samples when the document is updated.
  • bug 1414419: Vary MDN attachment CDN on ?revision=X
• Work to get Jenkins to push to Kubernetes is in progress in the following PRs:
  • bug 1406546: refactor groovy code to handle kumascript as well as kuma
  • bug 1406546: add code for deploying kumascript to stage
