     {client_renegotiation, false}, % prevent clients DoSing w/ renegs
     {versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must

Speeding up Docker builds in CI

Every time a build starts in a new agent, the docker build cache is empty, and thus a docker build will need to rebuild the entire image from scratch.
