Loading and base64'ing binary files

[Tyler Johnson]

Is there any way to do this in Jsonnet? My particular use case is I want to base64 some binary files to include in a kubernetes Secret.

[Igor Peshansky]

Is this basically https://github.com/google/jsonnet/issues/238?

You can use https://jsonnet.org/ref/stdlib.html#base64 to encode the bits.

You can't load a binary file unfortunately, because it has to be UTF-8. You can however base64 it on the commandline and read it as text with importstr.  You can then base64-decode / recode it in Jsonnet if you need to process it somehow.

As pointed out earlier, the usual solution is std.base64(importstr "yourfile.pem") which of course doesn't work for binary (non-UTF8) files.

If you really need to import non-utf8 files for kubernetes, I'd be happy to add a new builtin in kubecfg for this (probably return a base64 jsonnet string).  If that's something you want, please create a feature-request issue on that github repo.

The Sjsonnet implementation makes it really easy to add your own intrinsic functions implemented in Java, as the rest of the standard library is, so if anyone else is on Sjsonnet then you can always add support for loading binary-files-as-base64 yourself

I have exactly the same issue!

It might just be time to add importbin (which is pretty trivial to do)

Yup, same here.
