I would like to introduce Custom WAR Packager - a new tool for Jenkins administrators and developers. This tool allows packaging custom Jenkins distributions as WAR files, Docker images and Jenkinsfile Runner bundles. This tool allows packaging Jenkins, plugins, and configurations in a ready-to-fly distribution. Custom WAR packager is a part of the Ephemeral Jenkins controller toolchain which we presented in our A Cloud Native Jenkins blogpost. This toolchain is already used...

In our talk, we will focus on the following topics: Pluggable Storage, our...

On large-scale Jenkins instances controller disk and network I/O become bottlenecks in particular cases. Build logging and artifact storage were one for the most intensive I/O consumers, hence it would be great to somehow redirect them to an external storage. Back in 2016 there were active discussions about such Pluggable Storage for Jenkins. At that point we created several prototypes, but then other work took precedence. There was still...
