I've been there myself as Jenkins is indeed a very flexible tool. And I don't, by any means, claim to be an expert on dealing with it. Usually what I do is to peak at the documentation and at what others have implemented. Then I work on extending/modifying things to my needs. The GDB build job (currently running for aarch64/armhf/x86_64) I put together is here: https://git.linaro.org/ci/job/configs.git/tree/tcwg-gdb.yaml But I expect we will have to adjust this to make it a bit more generic so other architectures can use it. > > Besides, I seem to have glimpsed from the Linaro instance that the > builders use Docker.

That is a convenience so we can share hardware resources. It is possible to use real hardware to run the jobs. One may need to adjust the configurations a bit (distro, packages etc), but a job can automate some of that. Details about distros to use and packages to install still need to be investigated/discussed. > > Thanks. > Rainer >
