-# Building with a dedicated Jenkins CI instance
+# CouchDB and Jenkins CI
-## History
-
-Around April 2019, once Travis CI performance became so abysmal that the
-development team couldn't tolerate it any longer. We decided to move off
-of it entirely and onto our own dedicated Jenkins instance. Performance
-was bad because:
-
-* The Travis CI VMs are severely underpowered, leading to many
- unexpected test failures
-* The ASF wait queue for Travis was exceedingly long, with jobs
- sometimes taking 30-45 minutes just to _launch_
-* Our test suites (all 3 of Erlang, JavaScript and Elixir) had
- sporadic failures, requiring many re-launches of builds before
- we could move forward
-
-We also had other reasons to want to move to a dedicated server:
-
-* Credentials on the main Jenkins instance could be reused by *anyone*
- in the ASF
-* Credentials on the Travis CI setup should not contain credentials
- for things such as building binaries, to ensure the best possible
- security
-
-Other options we explored:
-
-* ASF BuildBot. This required a lot more work and couldn't guarantee
- availability of sufficient workers.
-* Circle CI, GitHub CI, etc.: Lack of availability of alternate binary
- platforms we've been asked to support (arm64v8, ppc64le) or alternate
- OSes (OSX, FreeBSD, Windows), though there is some support for either
- or both.
