any handy 0.12 cheatsheets?

Doesn’t look like that module has too many….hairy parts…..the rest of us have been using hacks on hacks on hacks

hey, a little question regarding 0.12, seems the feature of generating resources based on count and value list still keeps resources list in statefile in an indexed structure, is there a workaround? Still can’t remove an element from anywhere but the end of the list without forcing a replace on remaining elements.

That’s still a limitation in this release… They’ve indicated it will be addressed in 0.12.x, but no indication of what value of x… (Other than not 0)

aww, sucks, but thank you

Attributes as Blocks - Configuration Language - Terraform by HashiCorp

For historical reasons, certain arguments within resource blocks can use either block or attribute syntax.

I think it is a good idea to read the whole Terraform docs, because there are few things here and there. Attrs as blocks is one of the most trickiest

yeah, i’m not a fan of that change. makes it impossible for many resources to write modules that work for both tf 0.11 and tf 0.12

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

hah, is there even a point to try and make them compatible?

loren avatar
loren

i wanted an upgrade path of this kind:

  1. update modules to be cross-compatible as a patch release
  2. update the executing project to use tf 0.12
  3. leisurely update modules to leverage tf 0.12 syntax
loren avatar
loren

1 is fast, easy, and low risk

loren avatar
loren

and gives users an inflection point for their own upgrade paths. hashicorp is doing the same thing for providers with their SDK and with tf 0.11.14

I think adding version tags in your modules is the supported approach. Honestly this upgrade is going to be long enough and slow enough I suspect branches or forks will end up having to be the real world answer.

- vpc.label in .terraform/modules/vpc.label
There are some problems with the configuration, described below.

The Terraform configuration must be valid before initialization so that
Terraform can determine which modules and providers need to be installed.

Error: Attribute name required

  on .terraform/modules/dynamic_subnets/private.tf line 34, in resource "aws_subnet" "private":
  34:     ignore_changes = ["tags.%", "tags.kubernetes", "tags.SubnetType"]

Dot must be followed by attribute name.


Error: Attribute name required

  on .terraform/modules/dynamic_subnets/public.tf line 35, in resource "aws_subnet" "public":

Is there any roadmap for making the module 0.12 compatible? Let me know if I can be of help somehow.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

We will inevitably support 0.12, but not until there’s more mainstream adoption.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Most likely it will come from (cloudposse) customer demand.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

I think we might need to start with a master/0.12 branch and go from there.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

also, it will mess with versions. We’ll probably need to affix +0.12 to the semmver

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

e.g. 0.1.2+0.12

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

and doubt we’ll be backporting fixes.

Welcome suggestions from community on how we can straddle the two worlds.

i know they really tried to focus on making the 0.11 -> 0.12 migration easy (even providing a migration tool), but im curious to see how much of a headache (or lack thereof) it will be

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

Has anyone done his yet for a sizable terraform codebase?

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

(I guess I’m more interested in a non-monorepo migration)

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

…though this is a great case for mono-repo

loren avatar
loren

I’d expect similar types of updates, plus a little workflow around versioning… Pin references to nested modules (which you should be doing anyway), update leaf modules, release those updates as new versions, update parent modules once all nested/leaf modules are good

loren avatar
loren

For sure it’ll suck more if you feel the need to backport patches to support two major versions at once

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)

(basically, we have 130+ repos… so it’s gonna hurt. a lot and we don’t have a graph of how they are related, so planning it out is difficult)

btai avatar

nope, kinda worried to

btai avatar

even now some of the providers i use are pretty fickle (when using them together - azure, kubernetes, helm, etc)

well my first upgrade to 0.12 went well

:--1:1

but it was a relatively simple thing

so 20~ modules used about 40 times each, with about 3 or 4 resources per module. The most time consuming part was upgrading the modules, docs and publishing new versions etc.
