Mock is a simple program that will build source RPMs inside a chroot. It doesn't do anything terribly fancy other than populate a chroot with the contents specified by a configuration file, then build any input SRPM(s) in that chroot.
The content of a chroot is specified by the configuration specified with the -r option. The default configuration file is /etc/mock/default.cfg, which is usually a symlink to one of the installed configurations.
There is a site-wide configuration file, /etc/mock/site-defaults.cfg, which can be used to specify site-wide options. The shipped version of this file has no active options, but does have a list of all of the configuration options, examples of how to set them, and their default values.
For backwards compatibility, old-style commands, ("rebuild", "init", "clean", etc.) without leading '--' are still accepted, but are deprecated. See COMMANDS section, below, for detailed listing of all commands.
To use mock, a user should become a member of the mock group by adding their username to the mock line in /etc/group. This can be done with the following command:
sudo /usr/sbin/usermod -a -G mock $USER
Note that mock is not intended to be run directly as root.
--clean
Purge the chroot tree.
--scrub=TYPE
Completely remove the specified chroot or cache dir or all of the chroot and cache. TYPE is one of all, chroot, cache, root-cache, c-cache, or yum-cache.
--init
Initialize a chroot (clean, install chroot packages, etc.)
--rebuild
If no command is specified, rebuild is assumed. Rebuilds the specified SRPM(s). The buildroot is cleaned first, unless --no-clean is specified.
--buildsrpm
Builds the specified SRPM either from a spec file and source file/directory or from SCM. The buildroot is cleaned first, unless --no-clean is specified.
--shell
Run the specified command interactively within the chroot (which must already be initialized -- no 'clean' is performed). If no command specified, /bin/sh is run.
--chroot
Run the specified command non-interactively within the chroot (which must already be initialized -- no 'clean' is performed). Command output will be sent to the log files.
--installdeps
Find out deps for SRPM or RPM, and do a yum install to put them in the buildroot. Buildroot must already be initialized -- no 'clean' is performed
--install
Do a yum install PACKAGE inside the buildroot. Buildroot must already be initialized -- no 'clean' is performed
--update
Do a yum update inside the buildroot. Buildroot must already be initialized -- no 'clean' is performed
--remove
Do a yum remove PACKAGE inside the buildroot. Buildroot must already be initialized -- no 'clean' is performed
--orphanskill
No-op mode that simply checks that no stray processes are running in the chroot. Kills any processes that it finds using specified root.
--copyin
Copies the source paths (files or directory trees) into the chroot at the specified destination path.
--copyout
Copies the source paths (files or directory trees) from the chroot to the specified destination path.
--scm-enable
Enable building from an SCM (CVS/Git/SVN). The SCM repository must be configured in site-defaults.cfg before SCM checkouts are possible. SCM package and branch can be defined with --scm-option arguments, see site-defaults.cfg for more information.
-r CHROOT, --root=CHROOT
Uses specified chroot configuration as defined in /etc/mock/<chroot>.cfg. If none specified, uses the chroot linked to by /etc/mock/default.cfg
--offline
Run in 'offline' mode where we tell 'yum' to run completely from local cache. Also disables cache expiry for the mock yum cache.
--no-clean
Do not clean chroot before building package.
--cleanup-after
Clean chroot after building. Use with --resultdir. Only active for '--rebuild'.
--no-cleanup-after
Don't clean chroot after building. If automatic cleanup is enabled, use this to disable.
--cache-alterations
Rebuild the root cache after making alterations to the chroot (i.e. --install). Only useful when using tmpfs plugin.
--target=ARCH
This argument is passed to rpmbuild to specify the target arch to build. It defaults to whatever is specified for --arch, or whatever is specified in the config file as config_opts['target_arch'].
--arch=ARCH
Calls the linux personality() syscall to tell the kernel to emulate a secondary architecture. For example, building i386 packages on an x86_64 buildhost.
-D "MACRO EXPR", --define="MACRO EXPR"
Specify macro definitions used for the build. This option may be used multiple times, just as the rpmbuild --define option can be. For example:
--define "with_extra_cheese 1" --define="packager Monkey"
--with=OPTION
Enable configure OPTION for build. This option may be used multiple times. For example:
--with=extra_cheese
--without=OPTION
Disable configure OPTION for build. This option may be used multiple times. For example:
--without=anchovies
--resultdir=RESULTDIR
Change directory where resulting files (RPMs and build logs) are written. Resultdir can contain python-string substitutions for any variable in the chroot config. For example:
--resultdir=./my/"%(dist)s"/"%(target_arch)s"/
--uniqueext=text
Arbitrary, unique extension to append to buildroot directory name
--configdir=CONFIGDIR
Change directory where config files are found
--rpmbuild_timeout=SECONDS
Fail build if rpmbuild takes longer than 'timeout' seconds
--unpriv
Drop privileges before running command when using --chroot
--cwd=DIR
Change to the specified directory (relative to the chroot) before running command when using --chroot
-q, --quiet
Be quiet.
-v, --verbose
Output verbose progress information.
--trace
Enables verbose tracing of function enter/exit with function arguments and return codes. Useful for debugging mock itself.
--enable-plugin=PLUGIN
Enable the specified plugin. This option may be used multiple times.
--disable-plugin=PLUGIN
Disable the specified plugin. This option may be used multiple times.
--plugin-option PLUGIN:KEY=VALUE
Set plugin specific parameter. This option may be used multiple times.
-h, --help
Show usage information and exit.
--version
Show version number and exit.
/etc/mock/ - default configuration directory
/var/lib/mock - directory where chroots are created
To rebuild test.src.rpm using the Fedora 14 configuration for x86_64
mock -r fedora-14-x86_64 --rebuild /path/to/test.src.rpm
Note that the available configurations are found in the /etc/mock directory with the extension .cfg. To specify a configuration use the filename without the trailing .cfg extension.
To place the output RPMs and logs in a specified location.
mock -r fedora-14-i386 --resultdir=./my-results /path/to/your.src.rpm
To build a package from the default SCM repository configured in site-defaults.cfg use the following arguments.
mock -r fedora-14-i386 --scm-enable --scm-option package=pkg
