#variant - May 2019

FYI:
https://github.com/mumoshu/variant/issues/76

@mumoshu https://github.com/cloudposse/geodesic/pull/466

any thoughts?

this is like your anydeps but uses variant without overloading helm as package manager.

(as you can see the motivation is for #helmfile to fetch releases)

but will be also used to fetch binaries

though I confess i wrote this without looking at anydep and now that I do see a bunch of things I can do better

@Erik Osterman (Cloud Posse) I believe your approach does work and simpler, which is nice!

Your assumption would be that you don’t need transitive dependencies to be handled, right?

yea, not for this stage

no deps of deps

i think a "package" system would be better then; perhaps why you chose helm

@mumoshu have you considered a "default" command? e.g. if none of the args match, pass $* to some command

e.g. terraformctl would intercept any task defined, but if not defined, it would pass to terraform

basically, using variant to overload commands

@Erik Osterman (Cloud Posse) sounds like a great addition to variant!

@Erik Osterman (Cloud Posse) For variant (and also helmfile potentially) I got to think that we eventually need a tool like this:

https://github.com/mumoshu/versadep/blob/master/README.md

WDYT?

Here's a quick intro to variant I recorded for one of our developers: https://zoom.us/recording/play/4tqm82NFwAwrKQKyDPrLRiKnpoQQ3QVP0vgQzqs6ReXioWAU5msjIn9t4jfn8Fe6?continueMode=true

I just came to know about variant

i am not sure what advantage does variant have over regular bash scripts

consistent interface

proper arg validatin

very terse

most bash scripts have very poor argument handling

yep, and it provides a “upgrade path” to a golang app 🙂

you can use variant build and some scripts to produce a single executable that runs without variant

and even add extra commands written in golang to your cmd written in yaml

so if you feel outgrown from bash, variant allows you to gradually/fully migrate to golang.

it is currently flying over my head, i will have to check it out

i guess i will start with @Erik Osterman (Cloud Posse) intro video

so potentially we could replace https://github.com/cloudposse/geodesic/blob/master/rootfs/usr/local/bin/s3 with variant ?

Yes

Everything new we do is in variant

@rohit I think about it like this: makefile is good for the wrapping bash scripts (and other executables), and variant is better than makefile to do it 🙂
