Bosco Override Template

What is this?

This is a configuration template for the SLATE OSG HostedCE application. This application functions as an entrypoint for batch jobs entering a local cluster from the Open Science Grid.

Bosco is a component of the CE responsible for managing job submission to the computer cluster(s). Some attributes of bosco may need to be overridden/patched in order to get a functional CE at certain sites. This is because Bosco is not always able to determine environment specific details on the remote clusters.

A common example is the binary path for the batch system's executables. Bosco expects to find the executables in /usr/bin, but the remote batch system may have binaries come from somewhere else. This option can be overriden in bosco_override/glite/etc/blah.config

Batch system specific parameters can be added in the scripts found in bosco_override/glite/etc/blahp/

How to use

When preparing the configuration for a new SLATE OSG HostedCE you will need to setup a git repository which the application will use to clone the overrides to the remote cluster.

Simply fork this repository to a suitable location.

Rename your respository to whatever works best for you. I have named mine utah-bosco.

Change the RESOURCE_NAME directory to match name of your resource. This is specified in the SLATE application config (also called values.yaml)

Site:
  Resource: SLATE_US_UUTAH_LONEPEAK
  ResourceGroup: CHPC Group

In my case I would name this directory SLATE_US_UUTAH_LONEPEAK

After this you can change the files you need to override.

Files that are not overridden can be removed from the repository for simplicity.

You are now ready to point your CE application config at your forked repoository.

# Options to allow override of the bosco directory from arbitrary git repos
# Bosco override dirs are expected in the following location in the git repo:
#   <RESOURCE NAME>/bosco_override/
BoscoOverrides:
  Enabled: true
  GitEndpoint: "https://github.com/slateci/utah-bosco.git"
  RepoNeedsPrivKey: false
  GitKeySecret: none

It is also possible to store these values in a private repository configured with a private key stored as a SLATE Secret.

This repository can also be used as an example for what can be overriden to fix issues for an existing CE.
