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)almost 7 years ago

Has anyone done his yet for a sizable terraform codebase?

btaialmost 7 years ago

nope, kinda worried to 😂

btaialmost 7 years ago

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

Andrew Jeffreealmost 7 years ago

well my first upgrade to 0.12 went well

Andrew Jeffreealmost 7 years ago

but it was a relatively simple thing

Andrew Jeffreealmost 7 years ago

all our datadog monitors

Andrew Jeffreealmost 7 years ago

for all our customers

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.

- 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.

Nikola Velkovskialmost 7 years ago

ah 🙂

Nikola Velkovskialmost 7 years ago

This is from the https://github.com/cloudposse/terraform-aws-dynamic-subnets module.

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)almost 7 years ago

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

Erik Osterman (Cloud Posse)almost 7 years ago(edited)

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

Erik Osterman (Cloud Posse)almost 7 years ago

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

Erik Osterman (Cloud Posse)almost 7 years ago

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

Erik Osterman (Cloud Posse)almost 7 years ago

e.g. 0.1.2+0.12

Erik Osterman (Cloud Posse)almost 7 years ago

and doubt we'll be backporting fixes.

Nikola Velkovskialmost 7 years ago

Allright, thanks for the info.

Erik Osterman (Cloud Posse)almost 7 years ago

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

Erik Osterman (Cloud Posse)almost 7 years ago(edited)

And if the proposal above make sense.

found a bug in matchkeys, https://github.com/hashicorp/terraform/issues/21432

lorenalmost 7 years ago

looks like they might have just run the upgrade tool on everything?

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.

good to know: https://www.terraform.io/docs/configuration/attr-as-blocks.html

antonbabenkoalmost 7 years ago

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 🙂

lorenalmost 7 years ago

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

joshmyersalmost 7 years ago

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

Erik Osterman (Cloud Posse)almost 7 years ago

any handy 0.12 cheatsheets?
