I have a newbie question. How does one build ceph container which can be tested in cephadm cluster? I've had success compiling ceph with this command from the documentation ./src/script/build-with-container.py -d ubuntu22.04 -b build.u2204 -e build but container it leaves behind has no ceph binaries in $PATH or /usr/bin. I was testing on ubunut 22.04 with podman and v19.2.4 git tag. Second question, how distro specific are these container build scripts? My colleague couldn't build any images on ubuntu 26.04. I can build only ubnutu 22.04 images, centos9 and centos10 builds fail on v19.2.4 and v20.2.1 Third question, is there a reliable way to set number of jobs used during compilation? BUILD_MAKEOPTS=-j32 seems to work for some build targets but not for all. By default build system chooses -j16 on 32 core VM. Best regards Adam Prycki
