Description

This module creates a Toolkit runner that will install HTCondor on RedHat 7 or derivative operating systems such as the CentOS 7 release in the HPC VM Image.

It also exports a list of Google Cloud APIs which must be enabled prior to provisioning an HTCondor Pool.

It is expected to be used with the htcondor-configure and htcondor-execute-point modules.

Example

The following code snippet uses this module to create startup scripts that install the HTCondor software and adds custom configurations using htcondor-configure and htcondor-execute-point.

- id: htcondor_install
  source: community/modules/scripts/htcondor-install

- id: htcondor_configure_central_manager
  source: modules/scripts/startup-script
  settings:
    runners:
    - $(htcondor_install.install_htcondor_runner)
    - $(htcondor_configure.central_manager_runner)

- id: htcondor_configure_access_point
  source: modules/scripts/startup-script
  settings:
    runners:
    - $(htcondor_install.install_htcondor_runner)
    - $(htcondor_install.install_autoscaler_deps_runner)
    - $(htcondor_install.install_autoscaler_runner)
    - $(htcondor_configure.access_point_runner)
    - $(htcondor_execute_point.configure_autoscaler_runner)

A full example can be found in the examples README.

Important note

This module enables Linux firewall rules that block access to the instance metadata server for any POSIX user that is not root or condor. This prevents user jobs from being able to escalate privileges to act as the VM. System services and HTCondor itself can continue to do so, such as writing to Cloud Logging. This feature can be disabled.
