Subject Re: [DISCUSS] improve MXNet Scala release process
Date Sat, 28 Jul 2018 00:44:38 GMT
Hi all,

about the credential management: We already have a solution based on
restricted slaves [1] and AWS secrets manager [2] that is generally
classified to generate binaries and handle credentials. It was designed
with continuous deployment in mind, but we haven't tested it in that field
yet.

To properly assess the requirements, it would be great if we have this
security critical part outlined for each release pipeline. We could then
check and see if our existing solution matches all requirements or if
further work is necessary.

Best regards,
Marco
