Caching http://registry.npmjs.org/ aggressively with squid

We run a lot of project in our automated test environment and they spend a lot of time doing npm install. One way to speed up npm install and hammer the registry a little less is to use the http-version of the registry and to pass the requests through a proxy.

However, the npm requests include an authorization-header and the responses come with an ETag and Cache-Control: max-age=60, so with default squid settings there is a lot of roundtrips to registry.npmjs.org that result in 304's.

This is what the requests look like once npm has cached the first set of responses:

GET http://registry.npmjs.org/sntp HTTP/1.1

Credentials Management

This guide describes setting out a credential storage mechanism that is shared between the root account, aka releasr, and jenkins account. It intends to support and persist access credentials that are needed when authenticating with external services, primarily Docker Hub, for users wishing to access remote Docker images as part of their containerised services.

The following diagram aims to describe the control flow this setup intends to support.

This guide is a first, and a tad complicated sorry, pass at setting this up. It got us over the line for a couple of uses cases as well as working with automated build jobs.
