Hi Mikaël,

Thanks for this clarification.

Still, our Java library embeds the native (C) libraries for all the platforms we supports (x86, ARM, MacOS…).
Therefore, we need in a single Maven build to compile all the native libraries and to bundle them into a jar.
The current solution is to have Maven calling a Makefile which calls the various cross-compilation Docker containers to build the native libs, and then goes on with packaging and tests.
The great advantage of this, is that any user only needs to pre-install Docker (and SWIG) before to run a regular mvn command.

Do you see a solution to make this work in CBI with a custom pod template?

Cheers,
Julien

My question:
Is it possible for a build in CBI to pull/start Docker containers on the fly, and if yes, how ?

No, it's not possible for security reasons: letting people mount the docker socket basically grants root access to the host.

If you want to run your builds in custom docker container, you can use custom pod templates (https://wiki.eclipse.org/Jenkins#How_do_I_run_my_build_in_a_custom_container.3F)
