This repo contains packer templates and related files to build a CentOS image.
Available templates:
The version of CentOS to install is defined by the centos_version parameter in the above templates. As of 2017-02-28 the default version is 7.3.1611.
Here are the additions to the base install:
- yum --releasever=7.3.1611 update
- kernel-devel and kernel-headers are installed
- EPEL repo is enabled
- NTP is installed and enabled
- Manpages are installed
- SELinux is disabled
- UseDNS and PermitRootLogin are both set to no in /etc/ssh/sshd_config

Additional options can be included by specifying command line variables:
- To download the iso from a different mirror:
-var iso_url=http://... - To specify a different CentOS version:
-var centos_version=X.Y- You will most likely also need to pass iso_checksum and iso_url

-var root_hash='encrypted_string' - To have sssd installed specify the location of an sssd.conf:
-var sssd_conf='/local/path/to/sssd.conf' - An additional user-provided shell provisioner can be included:
-var custom_provisioner='/local/path/to/shell_script'
