How do I update the generated/ecs/ecs_nested.yml file?

[ruflin]

@watson run make or mage generate.

[ruflin]

@watson The place to update the docs is in the fields.yml then it will also generate the document you updated.

[webmat]

Yes, everything under generated/ you shouldn't touch, and only re-generate with make. No mage ;-)

[webmat]

@watson Yeah any tweaks to the schema should start in /schemas. Everything is generated from these files.

Getting this error when running make - wrong version of Go?:

# runtime/cgo
_cgo_export.c:3:10: fatal error: 'stdlib.h' file not found
make: *** [template] Error 2

We're trying to stay in line with the Golang version used by Beats, so 1.12.4 or .5 should do the trick.

Make sure your checkout of Beats is recent enough. Just git pull master should do. Not a great way to manage this external dependency, I know.

Not familiar at all with this error. Do you have the XCode command line tools installed?

I have Go 1.11.5 currently. That's probably the main issue then. I'll try to see if I can remember how it was installed - haven't used it in ages 😅

Does this repo require the beats repo to be cloned somewhere else on my computer? I don't have beats anywhere on my hard drive currently.

Yes

I'm trying to get rid of go in ECS, because I'm as familiar as you are with it LOL

You can likely upgrade Golang via homebrew.

Once you've upgraded Go, you can get the Beats code in the right place with go get github.com/elastic/beats or something to that effect. That'll put it in the right place for the imports to pick it up.

I upgraded Go to v1.12.5 and pull the latest version of beats, but now I think I probably have the wrong version of Python (v3.7.0). When running make I now get this error:

[webmat]

Yeah I have to migrate all this to Python 3 at some point, 🤦‍♂

So brew install python@2

[ruflin]

Can we document these pitfalls somewhere to make sure before we fix it we can point other contributors to it?

[watson]

I unfortunately don't have time to fix this PR right now. I've updated the PR to only change the file I was supposed to change, but the generated files have not been updated. If someone wants to take it on feel free 😃

[axw]

Thanks @watson!
I've regenerated the other bits and pushed to the branch.
