Even though official IPS repositories for Solaris are discontinued, you can still run Jenkins in Solaris via the jenkins webapp (jenkins.war). To quote from Jenkins installation doc:

Solaris, OmniOS, SmartOS, and other siblings

Generally it should suffice to install Java 8 and download the jenkins.war and run it as a standalone process or under an application server such as Apache Tomcat.

Some caveats apply:

  • Headless JVM and fonts: For OpenJDK builds on minimalized-footprint systems, there may be issues running the headless JVM, because Jenkins needs some fonts to render certain pages.

  • ZFS-related JVM crashes: When Jenkins runs on a system detected as a SunOS, it tries to load integration for advanced ZFS features using the bundled libzfs.jar which maps calls from Java to native libzfs.so routines provided by the host OS. Unfortunately, that library was made for binary utilities built and bundled by the OS along with it at the same time, and was never intended as a stable interface exposed to consumers. As the forks of Solaris legacy, including ZFS and later the OpenZFS initiative evolved, many different binary function signatures were provided by different host operating systems - and when Jenkins libzfs.jar invoked the wrong signature, the whole JVM process crashed. A solution was proposed and integrated in jenkins.war since weekly release 2.55 (and not yet in any LTS to date) which enables the administrator to configure which function signatures should be used for each function known to have different variants, apply it to their application server initialization options and then run and update the generic jenkins.war without further workarounds. See the libzfs4j Git repository for more details, including a script to try and "lock-pick" the configuration needed for your particular distribution (in particular if your kernel updates bring a new incompatible libzfs.so).

Also note that forks of the OpenZFS initiative may provide ZFS on various BSD, Linux, and macOS distributions. Once Jenkins supports detecting ZFS capabilities, rather than relying on the SunOS check, the above caveats for ZFS integration with Jenkins should be considered.
