ansible-htcondor

This role is designed to help you install and configure the HTCondor Job Manager. We tried to implement the same environment as the get_htconor script provided by HTCondor Homepage. Several settings used by our institution have been added.

Requirements

More tests will be needed, but until now there seems to be no special requirement. However, this role has the requirement that the EL system must be because the package was written to use the yum command. Other OS support will not be available for the time being. However, if anyone gives a Pull Request for this, we will add it.

Role Variables

This role still has many areas to improve. There are many features that are introduced as variables but not yet supported. Here is the contents of the default/main.yml file for this role.
