Configure SPANK plugins on AWS PCS

By default, store configuration files in /etc/aws/pcs/scheduler/slurm-version/plugstack.conf.d/.

To store your SPANK configuration in a different location, add your locations to a configuration file in the default directory.

The following example shows how to include configuration files from other directories:

# content of /etc/aws/pcs/scheduler/slurm-version/any-filename.conf  
include path-to-your-configuration-folder/*.conf  
include path-to-a-second-configuration-folder/*.conf

Store each configuration in a dedicated file, or in a common file. You can use multiple configuration files.

The following examples show sample configuration files:

# content of path-to-your-or-default-config-folder/filename-1.conf  
required path-to-plugin-1 arguments  
optional path-to-plugin-2 arguments

# content of path-to-your-or-default-config-folder/filename-2.conf  
required path-to-plugin-3 arguments

For additional information about how to configure your plugins, see the SPANK configuration documentation on the SchedMD website.

Important

Set folder permissions to prevent unauthorized changes to your plugin configuration.

Note

AWS PCS doesn't manage your SPANK plugins. If you get errors related to plugins, check the error logs on your compute nodes.

Note

Slurm incorrectly logs an error similar to the following when it loads your SPANK configuration:

error: "Include" failed in file /etc/slurm/plugstack.conf line 3

You can ignore this error. It doesn't affect how SPANK plugins work.
