JuliaRegistries setup for air gapped network

[Ashlin_Harris]

If you already have a Julia environment set up, or at least know what packages your users need, you can build it into a custom sysimage with PackageCompiler.jl. Then it’s just a matter of uploading the Julia source code and the sysimage to the network and setting up the shell environment. I’ve written a tutorial for this:

Secure systems: an alternate use case for PackageCompiler.jl

Julia’s package manager relies on internet access, so it can be challenging to make dependencies available on secure systems. PackageCompiler.jl compiles Julia code ahead of time, primarily for improved performance in certain workflows. In particular, generating a sysimage produces a performant stand-alone Julia session, and since its main drawback (version locking) is mitigated on secure systems, it seems to be the best approach for putting a Julia session on a system without internet access or…
