On a successful deploy, create a Sentry deploy via API
As additional information Releases in Sentry, it may be helpful to also track Deploys of those releases.
This expands on work done by @nolith in https://gitlab.com/gitlab-com/gl-infra/delivery/-/issues/838 to add an additional data point to when those releases were deployed to our environments. While we track this information elsewhere such as Grafana annotations and Slack, I think having additional insight into our deploys directly within Sentry would be helpful.
See https://docs.sentry.io/api/releases/post-release-deploys/ -- we should be able to do this in the .finish-success
stage of the deployer, possibly in the pipeline-notify
script.
