Why file names of kubectlProvider vary on different machines?

[adambro]

When working with my colleague I've noticed that cdk diff shows differences, even though we're on the same branch with the same code. Specifically the steps we've done are as follows:

1. Code on colleague laptop, pushed to origin.
2. Ran cdk deploy on the same laptop.
3. I've done pull and cdk diff shows some differences as follows.

The difference was in (generated) file names of some assets related to kubectlProvider if I read that diff correctly. Here's an excerpt of the cdk diff from one of out stacks (similar one was for every stack):

            [ ]   ]
            [ ] ]

I'm puzzled why those diffs are happening. I'd expect some kind of consistent hashing for those generated file names. If the consistent hashing is in place then why contents of those assets (Lambda functions?) varies on different machines?

[indrora]

Does this still happen?

[adambro]

I'm not using it anymore, but asked my colleague and it seems to be solved now. No differences on hashing assets any more.

However he noticed differences in .CDKMetadata.Properties.Analytics metadata, because it contains encoded NodeJS version. But that is not that relevant IMHO.

Yeah I was going to ask if the Node version differed, but I don't think that matters for the asset hash and only comes into play for the analytics.
