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
also, I’m bummed that helm-s3 still doesn’t support public repos
yep, we shouldn’t be tied to helm-s3 nor s3.
anydep can be enhanced to leverage any helm plugin.
so perhaps we can add another backend (http, github, etc) to anydep and serve both use-cases of mine and your deps

@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?
2019-05-07
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
Haven’t tested it with deeply nested commands, but I’ve added the initial support for default commands.
The top-level script is run when if is defined and no sub-task that matches the provided arguments found.
its available since v0.29
wow, that’s clever. I like how you kept it consistent with the rest of variant. hadn’t thought to implement it that way, but i like it.
@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?
the example config doesn’t make sense at all. please take it as purely for showing how the config syntax look like
Wow, yes, I think you are on to something
Consider adding semver
But that is more for GitHub tags/release
thx for sharing!
probably we need to explore more sources other than github tags/releases as well, like curl from any http sources as your deps
probably what need for versadep would look something like a declarative fetch + additional sources?
oh, and i wanted versadep to setup PATH for us, like rbenv does for ruby
Aha so you can vendor everything
exactly!
Btw have you ever explored terraform vendoring? Not easy
not at all. i’d love to know your experience!
For modules.. that nest modules. Only bringing it up because it’s something we’ve been tasked with solving at some point
can you nest terraform modules? i wonder how it works when multiple modules refer to/nest different versions of the module
yep, we do extreme nesting
sometimes 3-4 levels deep. maybe more.
terraform clones every reference of a module to .terraform/modules
each one checked out to the version referenced
it uses some hashed folder which is presumably the github url with version info

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

@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
