Package Management and synchronisation - kraut-computing/siegfried GitHub Wiki

We use the default gentoo package manager portage. To synchronise our nodes we use robert as our build node and share binary packages.

Setup Server node

edit /etc/portage/make.conf to build binaries
FEATURES="buildpkg"
export binaries via NFS
- /etc/exports : /usr/portage/packages <clients>(ro,no_subtree_check,root_squash)
- /etc/init.d/NFS restart
- add NFS to runlevel

mount binaries
/etc/fstab : robert:/usr/portage/packages /usr/portage/packages nfs defaults 0 0
mount /usr/portage/packages/
edit /etc/portage/make.conf
EMERGE_DEFAULT_OPTS="--usepkgonly --rebuilt-binaries"

TODO: vorher testen, ...

We use Puppet to manage the packages on the system.

All settings are in <PUPPET_CONFIG_DIR>/manifests/10_packages.pp

Add a line to the setupfile to install or uninstall packages

package { "<package id>[:slot]":
    ensure  => <latest/version/absent>,
    [package_settings => {
        use    => "<useflags>",
    }]
}

for use flages on dependencies remove the ensure line.
