yumbootstrap is a tool for installing Yum-based distributions (Red Hat,
CentOS, Fedora) in a chroot directory. Idea behind it is stolen from Debian's
debootstrap. It's planned for yumbootstrap to work along with templates for
lxc-create.
There is another project of similar purpose called Rinse. yumbootstrap differs from Rinse as follows:
- yumbootstrap uses Yum to resolve dependencies, so adding packages to installation list is easier (no need to track dependencies manually).
- Using multiple Yum repositories for installation is supported.
- yumbootstrap checks signatures on installed RPM packages.
- yumbootstrap doesn't depend on Yum mirror to list directory contents, so it's less work to setup local mirror usable with yumbootstrap.
Listing available suites:
# /usr/sbin/yumbootstrap --list-suites
centos-5
centos-6
...
fedora-19
fedora-20
Installing centos-6 suite to /mnt/chroot/centos-6-chroot:
# /usr/sbin/yumbootstrap --verbose centos-6 /mnt/chroot/centos-6-chroot
Installing centos-6 suite, including some custom packages:
# /usr/sbin/yumbootstrap --verbose \
--include=openssh-server --group=Core \
centos-6 /mnt/chroot/centos-6-chroot
Installing centos-6 suite, installing custom packages by hand from parent OS:
# CHROOT=/mnt/chroot/centos-6-chroot
# /usr/sbin/yumbootstrap --verbose --no-scripts centos-6 $CHROOT
# yum --installroot=$CHROOT -c $CHROOT/yumbootstrap/yum.conf install ...
# /usr/sbin/yumbootstrap --verbose --just-scripts $CHROOT
For Debian-based distributions, dpkg-dev and fakeroot are required.
dpkg-buildpackage -b -uc
dpkg -i ../yumbootstrap*.deb
For Red Hat derivatives you need rpm-build.
make srpm
rpmbuild --rebuild yumbootstrap-*.src.rpm
yum localinstall --nogpgcheck /usr/src/redhat/RPMS/*/yumbootstrap-*.rpm
