Puppet Class: epics

Defined in:
manifests/init.pp

Summary

Global configuration for IOCs

Overview

This class takes care of all system-wide tasks which are needed in order to run a soft IOC. It installs required software and prepares machine-global directories and configuration files.

Parameters:

  • iocbase (Stdlib::Absolutepath) —

    All IOC directories are expected to be located in a central directory. This parameter specifies the path to this base directory. Defaults to ‘/usr/local/lib/iocapps’.

    Note: Keeping all IOC directories in a central place is required to maintain compatibility with [sysv-rc-softioc](github.com/epicsdeb/sysv-rc-softioc). This restriction might be dropped in the future.

  • owner (String) —

    Owner of files/directories shared by all IOC instances (like the log directory). Defaults to ‘root’.

  • group (String) —

    Group of files/directories shared by all IOC instances (like the log directory). IOCs are also running under this group. Defaults to ‘softioc’.

  • gid (Optional[Integer]) (defaults to: undef) —

    Define the group id of the group the IOCs are run as. The gid will be picked automatically if this option is not specified.
