1316112 - please deploy balrog 2.13 to stage/prod

Status: RESOLVED FIXED

(Cloud Services :: Operations: Deployment Requests - DEPRECATED, task)

Description

[[e-mail] (:bhearsum)]

Balrog version 2.13 is ready to be pushed to stage. Please deploy the new Docker image (master-2016-11-08-20-17) the admin and public webapps, and the new Docker image for the Agent (master-2016-11-08-20-17).

We'd like the production push for this to happen sometime between 11am and 1pm pacific on Wednesday, November 9th, 2016.

This push requires a schema change that needs to be done _prior_ to the new code going out. That can be performed by running the Docker image with the "upgrade-db" command, with DBURI set. This should result in the creation of a few new tables (user_roles, user_roles_history, rules_scheduled_changes_conditions, and rules_scheduled_changes_conditions_history).

Also of note in this push are https://github.com/mozilla/balrog/pull/170, which bumps Cache-Control to 90s, and bug 1312562, which should fix a high-frequency Traceback we're seeing on Sentry, and reduce load on the public nodes.

Stage database updated and both admin/web have been updated.

Stage looks good, we're ready to deploy after the usual nightly spike of admin requests dies down.

Deployed to production yesterday.
Appears the new settings have reduced some of the balrog load and the number of servers at peak by about 20% from the previous stack. The effects of adding sentry are still about double the number of servers with sentry disabled.
