Why does the service account need privileged?

[christianh814]

In the Readme, it states...

To make sure the pipeline has the appropriate permissions to store images in the local OpenShift registry, we need to create a service account.

Then it has you running the following

oc adm policy add-scc-to-user privileged -z pipeline

After looking (albeit briefly) through this repo, there's nothing that suggest that you need privileged set. The SCC privileged should RARELY be used, unless absolutely necessary. And 9/10, people that think they need it, really don't (it's just they don't know which SCC to use).

I'm always cautious of anything that says I need privileged set.
