A 'simple' chroot build environment manager for building RPMs.

Mock is used by the Fedora Build system to populate a chroot environment, which is then used in building a source-RPM (SRPM). It can be used for long-term management of a chroot environment, but generally a chroot is populated (using DNF), an SRPM is built in the chroot to generate binary RPMs, and the chroot is then discarded.

This is an area for developers. You may be looking for user documentation.

Mock currently has one active branch plus main.

• main - This is used for releasing and developing the latest Mock version. If you want to send patches, you probably want this branch.
• mock-2 - This branch is used for Mock v2.x, for EL-7, bug-fixes-only mode.
• mock-1.4 - End of life, there will be no changes.
• mock-1.3 - This branch was used for EL-6, EOL.
• mock-1.0 - This branch was used for EL-5, EOL.

Do you have a patch, an idea, or just a question? You can write to buildsys mailing list or try Fedora Build System Matrix channel. We prefer email though.

If you hate mailing lists for some reason (we still prefer it) - you can use Discussions.

git clone https://github.com/rpm-software-management/mock.git
cd mock
cd mock-core-configs
tito build --rpm
cd ../mock
tito build --rpm
