@akosiaris is this done then?

Helm files were added but then had to be reverted as the build no longer worked.

Addition of helm file to zotero was temporarily removed in this change: https://gerrit.wikimedia.org/r/#/c/mediawiki/services/zotero/+/538171/

And removed from citoid in this change https://gerrit.wikimedia.org/r/#/c/mediawiki/services/citoid/+/514809/

Both unrelated to either helmfile or scap-helm. Both of those were to instruct the pipeline to do integration/e2e tests which isn't fully fleshed out yet.

But otherwise, yesI think this is done. scap-helm is fully deprecated now (it won't even work if you try to use it) and https://wikitech.wikimedia.org/wiki/Migrating_from_scap-helm does indeed have the HOWTO for deploying using helmfile
