ControlTier 3.4.x doesn’t include a yum module by default. I found this discussion in the mailing list which allowed me to achieve what I wanted. Following are instructions on installing the custom module, perform this on your CT server.

• Download YumModules.zip (found in the above link)
• mkdir -p /tmp/scratch/modules
• mv YumModules.zip /tmp/scratch
• cd /tmp/scratch
• unzip YumModules.zip -d modules
• ctl -p my-project -m ProjectBuilder -c build-library – -name yum -basedir /tmp/scratch -targetdir /tmp/target -upload

You may have to run install command on all your nodes to pickup the new module.

• ctl-depot -p my-project -a install
