please someone tell me what i am doing worng

Shtrullabout 7 years ago

and i am getting back

Shtrullabout 7 years ago

seems like it founr the right subent id but ignores it

Shtrullabout 7 years ago

when i remove the module.main.web_public_subnets[0].id and hard code the subnet it works

Shtrullabout 7 years ago

and this happens also if i make module.main.web_public_subnets output to be only one var and then remove the [0]

Shtrullabout 7 years ago

never mind 😞 i added .id but forgot that i took the value from an output and not the resource output

Erik Osterman (Cloud Posse)about 7 years ago

it's dirty. it's nasty. but if you need terraform-docs to work with 0.12, it works for us.

Erik Osterman (Cloud Posse)about 7 years ago

antonbabenkoabout 7 years ago

Awesome! Thanks @Erik Osterman (Cloud Posse)!

Nikola Velkovskiabout 7 years ago

A small appreciation to hands down one of the best modules out there


module "label" {
  source    = "git::<https://github.com/cloudposse/terraform-null-label.git?ref=0.12.0>"
  stage     = local.stage
  name      = local.name
  delimiter = "-"
  tags = {
    "<http://kubernetes.io/cluster/${module.label.id}|kubernetes.io/cluster/${module.label.id}>" = "shared"
  }
}

Nikola Velkovskiabout 7 years ago

Not sure if this will work in 0.11 though.

Erik Osterman (Cloud Posse)about 7 years ago

thanks @Nikola Velkovski!! 😃 comments like these is what keeps us going!

@Erik Osterman (Cloud Posse) what is the problem with the current terraform-terraform-label pr for 0.12.. I'd ike to push dynamodb to 0.12. Also current travis config fails for 0.12 still if im not mistaken.

Erik Osterman (Cloud Posse)about 7 years ago

@Andriy Knysh (Cloud Posse) started working on it but had to take some days off

Erik Osterman (Cloud Posse)about 7 years ago

We need to take a few steps with each module

Erik Osterman (Cloud Posse)about 7 years ago

First updating it to use Codefresh where we have all the 0.12 tooling in place

Erik Osterman (Cloud Posse)about 7 years ago

I will try to rush this out though for you if it’s a blocker

niekabout 7 years ago

Hi,

I just started to upgrade the gilab-runner-spot-module (for AWS) to TF 0.12. Would be great if you can help me with the following questions.

I used the tool terraform-docs to generate documentation of the variables, this tool seems not working (yet) for 0.12. Does anybody knows / uses an alternative approach?

Does anybody has a tip what is the best way to upgrade a data "aws_ami". In my TF 0.11 module I had provided the option to inject the filter via a variable as follow:


variable "ami_filter" {
  type        = "list"

  default = [{
    name   = "name"
    values = ["amzn-ami-hvm-2018.03*-x86_64-ebs"]
  }]
}

data "aws_ami" "runner" {
  most_recent = "true"

  filter = "${var.ami_filter}"

  owners = ["${var.ami_owners}"]
}

Does anybody has a good example how I can keep the filter(s) configurable in tf 0.12?

niekabout 7 years ago

Oops, already hab an answer on the filter question, map with a dynamic block

davidvasandaniabout 7 years ago

Is it possible to taint an entire module yet?

Rohit Vermaabout 7 years ago

hi all, seems like terraform-null-label is not compatible with terraform 0.12. The same module being used in all modules make them kind of unusable too

Andriy Knysh (Cloud Posse)about 7 years ago

starting from https://github.com/cloudposse/terraform-null-label/releases/tag/0.12.0, it does support TF 0.12

Andriy Knysh (Cloud Posse)about 7 years ago

https://github.com/cloudposse/terraform-null-label/releases

Andriy Knysh (Cloud Posse)about 7 years ago

to use it with TF 0.12, pin to the latest release

Andriy Knysh (Cloud Posse)about 7 years ago

to use with TF 0.11, pin to 0.11.1

Rohit Vermaabout 7 years ago

then we have to change this in all the modules correct, i can send pr for the modules which we uses.

Andriy Knysh (Cloud Posse)about 7 years ago

we have to update all the modules, we are working on it now

Andriy Knysh (Cloud Posse)about 7 years ago

PRs are welcome, thanks 🙂

Rohit Vermaabout 7 years ago

or may be a better solution is https://dependabot.com/terraform/

Rohit Vermaabout 7 years ago

which should fix this across all repos for you

Rohit Vermaabout 7 years ago

have you tried that?

Andriy Knysh (Cloud Posse)about 7 years ago

we are using dependabot

Andriy Knysh (Cloud Posse)about 7 years ago

not sure if it’s possible to automatically convert everything to TF 0.12

Andriy Knysh (Cloud Posse)about 7 years ago

works in simple cases

Andriy Knysh (Cloud Posse)about 7 years ago

but usually you have to manually fix/update the code after the conversion

Andriy Knysh (Cloud Posse)about 7 years ago

as far as I’ve seen it, the automatic conversion can’t work in some cases or breaks code in other cases

Rohit Vermaabout 7 years ago

i though you only need to update the null-label dependency across all projects.

Andriy Knysh (Cloud Posse)about 7 years ago

if your modules are TF 0.11 and you point them to null-label 0.12, will it work?

Rohit Vermaabout 7 years ago

i didn't tried null-label 0.12 yet. What I do know is you can make null-label 0.12 work with both 0.11 and 0.12.

Rohit Vermaabout 7 years ago

If its not working for any particular syntaxes, should raise a bug in terraform

Rohit Vermaabout 7 years ago

anyways you can specify that modules with tag version like 2.x only support 0.12

Andriy Knysh (Cloud Posse)about 7 years ago

that’s what we do https://github.com/cloudposse/terraform-null-label/blob/master/terraform.tf

Andriy Knysh (Cloud Posse)about 7 years ago

will not work with TF 0.11

Andriy Knysh (Cloud Posse)about 7 years ago

if your modules are TF 0.11

Rohit Vermaabout 7 years ago

i got it, you are saying automated null-label bump is not satisfactory since you want to address tagging along with it.

Rohit Vermaabout 7 years ago

anyways I will send pr for the modules which we are using.

Andriy Knysh (Cloud Posse)about 7 years ago

i mean when you update your modules to TF 0.12 and if the modules use the label, you will bump the label version in the new TF 0.12 code

Andriy Knysh (Cloud Posse)about 7 years ago

automated label bump to TF 0.12 in the module that supports only 0.11will not work

Rohit Vermaabout 7 years ago

that i agree, but if we fixed the deps and ci runs auto terraform 0.12upgrade --yes we can easily check narrow down the errors. Few modules like https://github.com/cloudposse/terraform-aws-key-pair.git don't need anything apart from label bump and upgrade.

Rohit Vermaabout 7 years ago

anyways there is a faster way which is clone all repos and do sed to replace version.

Rohit Vermaabout 7 years ago

so automation won't be worth it

Erik Osterman (Cloud Posse)about 7 years ago

Dependabot is awesome but without automated tests, a sure fire way to absolutely break everything with regressions

Erik Osterman (Cloud Posse)about 7 years ago

We tried it on a handful of repos about a year ago and quickly things started breaking (aka GitHub issues started spiking)

Erik Osterman (Cloud Posse)about 7 years ago

So as part of our upgrading to 0.12 we are trying to add more tests with terratest and bats

Erik Osterman (Cloud Posse)about 7 years ago

That way we catch regressions or at least have a way to test for them as they arise in the future

Rohit Vermaabout 7 years ago

yup ci should have better tests for automations

Rohit Vermaabout 7 years ago

But with 100+ modules we should work in that direction as well. I would love to help with something you required.

Rohit Vermaabout 7 years ago

one more thing I would recommend is to have version.tf file. The automatic upgrade does create this file and its easy to identify current terraform version for modules by just looking at the presence of file.

Erik Osterman (Cloud Posse)about 7 years ago

@Rohit Verma would massively appreciate some help

Erik Osterman (Cloud Posse)about 7 years ago

I will type up some guidance

Rohit Vermaabout 7 years ago

today i sleep, tomorrow morning I would try an approach to bump all those modules which requires lesser tinkering with some scripts.

Erik Osterman (Cloud Posse)about 7 years ago

If you have time to do a quick call this week that would be awesome too

Erik Osterman (Cloud Posse)about 7 years ago

Rohit Vermaabout 7 years ago

the part where i got lazy is fork and raise pr 😛

Erik Osterman (Cloud Posse)about 7 years ago

You were working with some in house git bots, right?

Rohit Vermaabout 7 years ago

yes but they are mostly chatops related thing, and work within an org

Erik Osterman (Cloud Posse)about 7 years ago

Did you finish rolling out test-infra used by istio?

Erik Osterman (Cloud Posse)about 7 years ago

And k8s

Rohit Vermaabout 7 years ago

no but we did the vanilla prows one and hooked with tekton

Rohit Vermaabout 7 years ago

you can avoid tekton and can continue use cloudfresh in parallel

Erik Osterman (Cloud Posse)about 7 years ago

Btw office hours today at 11:30 - in 1.5 hours

Rohit Vermaabout 7 years ago

i got severe cold, and its already past 10 pm for me

Erik Osterman (Cloud Posse)about 7 years ago

Oh no! Definitely get some rest

Rohit Vermaabout 7 years ago

early morning person, i probably won't be able to attend any of your office hours till I am in bangalore.

Rohit Vermaabout 7 years ago

Will catchup tomorrow morning with what I was able to do.

Rohit Vermaabout 7 years ago

Also you need some marking strategy whether the repo is done, may be presence of version.tf or a specific tag versioning method

Rohit Vermaabout 7 years ago

I would recommend version.tf

Rohit Vermaabout 7 years ago

If you agree can we add that to null label repo

Andriy Knysh (Cloud Posse)about 7 years ago

sure

Andriy Knysh (Cloud Posse)about 7 years ago

we added it to the examples https://github.com/cloudposse/terraform-null-label/blob/master/examples/complete/versions.tf, which get tested automatically

Callum Robertsonabout 7 years ago

That label module is the hotness

joshmyersabout 7 years ago(edited)

👋 hey folks - if you were starting a new project, thoughts on using 0.12 from the get go….? cc @antonbabenko @Erik Osterman (Cloud Posse) @Andriy Knysh (Cloud Posse)

Andriy Knysh (Cloud Posse)about 7 years ago

should be ok. Not sure about it 100% since we converted just a few modules, working on the rest now

joshmyersabout 7 years ago

Nice, any “fun” with lists of maps/other workarounds we came up with for enabled/disabed etc?

Andriy Knysh (Cloud Posse)about 7 years ago

(we did not get to those modules yet)

Andriy Knysh (Cloud Posse)about 7 years ago

but a lot of fun with expressions like this https://github.com/cloudposse/terraform-null-label/blob/master/main.tf#L40

joshmyersabout 7 years ago

hah, I bet

joshmyersabout 7 years ago

Cheers Andriy

Erik Osterman (Cloud Posse)about 7 years ago

0.12 is definitely more enjoyable

Erik Osterman (Cloud Posse)about 7 years ago

I would start fresh with that

marcabout 7 years ago

are many of you guys running into:

Error: Failed to instantiate provider "aws" to obtain schema: Incompatible API version with plugin. Plugin version: 4, Client versions: [5]

I get this with 0.12.2.

the solutions I seem to find out there are to recompile tf, but wondered if people had a workaround?

lorenabout 7 years ago

What version of the aws provider are you using?

marcabout 7 years ago

  version             = "~> 2"

marcabout 7 years ago

huh, I guess

marcabout 7 years ago

  version             = "~> 2.16"

works

lorenabout 7 years ago

Ahh, they must have updated the schema version?

Erik Osterman (Cloud Posse)about 7 years ago

Rohit Vermaabout 7 years ago

why have terraform-terraform-label and terraform-null-label. Are we planning to deprecate anyone?

Erik Osterman (Cloud Posse)about 7 years ago

terraform-terraform-label was introduced as a simpler alternative to terraform-null-label which grew unwieldy in 0.11

Erik Osterman (Cloud Posse)about 7 years ago

with 0.12, terraform-null-label is once again sane, but we'll continue supporting terraform-terraform-label

Erik Osterman (Cloud Posse)about 7 years ago

and both have been updated to 0.12

Callum Robertsonalmost 7 years ago

Thanks @Erik Osterman (Cloud Posse) 😄
