We are currently working on supporting continuous deployments, but it seems that no suitable tools are available. We don't have particularly outlandish requirements, we want something that:

- Can be triggered via a webhook or from a GitHub PR/comment - Can queue up multiple releases (of the same or different services) and deploy them in series - Flexibility (works not only with Kubernetes)

So far we've looked at Tekton, Buildbot, and GoCD. It seems none of them support our use cases: GoCD and Tekton don't support queuing of releases and Buildbot requires so much customization that we might as well continue building our own solution.

What do other modern medium-sized software companies use to make continuous deployment a reality?
