In the cloudposse repos, how is the terraform.md file generated in the docs folder on the repos? Some Automated script that pulls from the variables.tf?

@Jeff McCollum hi

Andriy Knysh (Cloud Posse)over 7 years ago

this channel is not for Cloud Posse repos, it’s for https://github.com/terraform-aws-modules/

Andriy Knysh (Cloud Posse)over 7 years ago

but to answer your question, we run the following commands:

Andriy Knysh (Cloud Posse)over 7 years ago


make init
make readme/deps
make readme

Jeff McCollumover 7 years ago

Ah ok, sorry about that. Thanks I'll take a look at that.

Andriy Knysh (Cloud Posse)over 7 years ago

the targets are in https://github.com/cloudposse/build-harness/blob/master/modules/readme/Makefile

Andriy Knysh (Cloud Posse)over 7 years ago

build-harness gets included in the repo’s Makefile, e.g. https://github.com/cloudposse/terraform-aws-key-pair/blob/master/Makefile#L6

is there a module for an ASG with a mixed instances policy?

Jamie Nelson (BitFlight)over 7 years ago

@cabrinha yes, sorta. https://github.com/bitflight-public/terraform-aws-ecs-cluster

Hi guys I am running into an issue with the module terraform-aws-cloudfront-s3-cdn. I am looking to create a S3 website backed by Cloudfront. As part of the same code I am creating:
- Route53 public hosted domain
- Cloudflare NS records
- ACM cert validated by dns
All of the above works perfectly but when I add the terraform-aws-cloudfront-s3-cdn I get

Error: Reference to undeclared resource

  on .terraform/modules/cloudfront_s3_cdn.dns/main.tf line 5, in data "aws_route53_zone" "default":
   5:   depends_on = [aws_route53_zone.this]

Bruce Dominguezover 7 years ago

Any ideas? Do I need to create the Route53 resources first before running this module?

Andriy Knysh (Cloud Posse)over 7 years ago

@Bruce Dominguez if terraform says undeclared resources, then check if you have those resources in the code

Andriy Knysh (Cloud Posse)over 7 years ago

to create an S3 website with CloudFront CDN, this might help https://sweetops.slack.com/archives/CB6GHNLG0/p1562177967452800

Guys do you have idea whats wrong with subnet module which calls label?

Error: Missing resource instance key

  on .terraform/modules/private_subnets.private_label/outputs.tf line 2, in output "id":
   2:   value = "${null_resource.default.triggers.id}"

Because null_resource.default has "count" set, its attributes must be accessed
on specific instances.

For example, to correlate with indices of a referring resource, use:
    null_resource.default[count.index]

Milos Backonjaover 7 years ago

i see what the error is but is it updated to work with 12>?

Erik Osterman (Cloud Posse)over 7 years ago

@Andriy Knysh (Cloud Posse) ☝️

Andriy Knysh (Cloud Posse)over 7 years ago

@Milos Backonja what module are you using? (and what terraform version?)

Andriy Knysh (Cloud Posse)over 7 years ago

if you are using https://github.com/cloudposse/terraform-aws-dynamic-subnets, it’s updated to TF 0.12

Andriy Knysh (Cloud Posse)over 7 years ago

usage example https://github.com/cloudposse/terraform-aws-dynamic-subnets/tree/master/examples/complete

Milos Backonjaover 7 years ago

Thanks @Andriy Knysh (Cloud Posse). I tried before I post message with dynamic sub-nets module and that one is working.
I have issue with named subnets and multi-az subnets modules. I set terraform-null-label to version 0.14.0 (which is used in dynamic subnets module) and was able to eliminate errors regarding count , but I started to see new errors.
I use terraform 0.12.x

Andriy Knysh (Cloud Posse)over 7 years ago

Those are not converted to 0.12 yet

Andriy Knysh (Cloud Posse)over 7 years ago

Only dynamic subnets

Bruce Dominguezover 7 years ago

Thanks @Andriy Knysh (Cloud Posse) I will check out the example. 🙂

Bruce Dominguezover 7 years ago

Another one, I got module terraform-aws-cloudfront-s3-cdn working by creating the acm and parent zone prior to using the module. Just a quick question. Do I need to create an Alias record to now point to the created CDN?

Andriy Knysh (Cloud Posse)over 7 years ago

CDN itself uses cloudfront.net domain

Andriy Knysh (Cloud Posse)over 7 years ago

To access the site from your domain, you need to create an alias record

Bruce Dominguezover 7 years ago

Thanks @Andriy Knysh (Cloud Posse) so I need to create an alias record X.mycompany.com to point to the cf_domain_name output (xxx.cloudfront.net).

Bruce Dominguezover 7 years ago

Thanks for the help 🙂

Bruce Dominguezover 7 years ago

Also is there a good fargate module?

Bruce Dominguezover 7 years ago

Is it best to create an ECS Fargate resource then use the modules for terraform-aws-ecs-container-definitionand terraform-aws-ecs-alb-service-task? or is there a simpler way to provision an Fargate cluster for a simple app?

Andriy Knysh (Cloud Posse)over 7 years ago

@Bruce Dominguez we have a complete working example here https://github.com/cloudposse/terraform-root-modules/tree/master/aws/ecs

Andriy Knysh (Cloud Posse)over 7 years ago

we use it to deploy atlantis on ECS Fargate

Andriy Knysh (Cloud Posse)over 7 years ago

it uses https://github.com/cloudposse/terraform-aws-ecs-atlantis and https://github.com/cloudposse/terraform-aws-ecs-web-app

Bruce Dominguezover 7 years ago

Thanks @Andriy Knysh (Cloud Posse) 🙂

Is there a way i can set a flag to enable/disable cross region replication using terraform-aws-modules/rds/aws moudle ? I do not want to enable replication in non production region but want it in production

rohitover 7 years ago

Is anyone aware of how to do this ?

rohitover 7 years ago

any ideas about my above question ?

joshmyersover 7 years ago

Anyone had https://github.com/cloudposse/terraform-aws-tfstate-backend/blob/master/main.tf#L104 not set versioning correctly?

joshmyersover 7 years ago

Looks like it should do the right thing….but I noticed no versioning on the state bucket

joshmyersover 7 years ago

from statefile ^^

joshmyersover 7 years ago

Manually flipped the versioning flag on the bucket, re ran a plan, no-op

Erik Osterman (Cloud Posse)over 7 years ago

0.12 or 0.11?

joshmyersover 7 years ago

0.11, using the 0.11 release of the module (0.7.0)

joshmyersover 7 years ago

https://github.com/terraform-providers/terraform-provider-aws/issues/8051 sounds like what I’m seeing, in terms of TF not wanting to change it back at least

joshmyersover 7 years ago

Not sure why it was never set though..

joshmyersover 7 years ago

While I remember, can we get a new release of https://github.com/cloudposse/terraform-aws-iam-account-settings/releases cut?

Bertieover 7 years ago

what's the recommended pattern for dealing with security groups for ec2 instances? should i create them in their own plan?

Joshua Hansenover 7 years ago(edited)

question and it may be because i’m new to tf, but using https://github.com/cloudposse/terraform-aws-rds/releases 0.9.0 - copying and pasting the example as-is i’d expect tf plan to more or less work as-is knowing i obviously need to assign the sg’s and subnets. but i’m getting more than that (attached in thread).

does anyone know what the aws elasticbeanstalk config option CONFIG_SOURCE is for? I can't find any aws documentation on it. https://github.com/cloudposse/terraform-aws-elastic-beanstalk-environment/blob/01d405201c192ee1948ea97bff6742140b1cfbba/main.tf#L707

Hey Folks, Trying to find some Terraform Modules related to AWS - app stream service ( for creating fleets and stacks) any help appreciated

Blaise Pabonabout 7 years ago(edited)

So I'm thinking of installing a private gitlab .... and before I cobble together these modules to reproduce their reference config (see diag below), I wanted to check here to make sure there wasn't a better way:

Blaise Pabonabout 7 years ago

hmmm, it looks like this tutorial may do the trick, thanks https://medium.com/@aloisbarreras_18569/architecture-overview-of-gitlab-on-aws-d260c16a2ad7
