Has anyone here referenced remote state output in 0.12 using Terraform Cloud remote state storage? I’m following their reference example at https://www.terraform.io/docs/backends/types/remote.html but it’s bailing with Expected an equals sign ("=") to mark the beginning of the attribute value. on the workspaces {} block.

Backend Type: remote - Terraform by HashiCorp

Terraform can store the state and run operations remotely, making it easier to version and work with in a team.

@sweetops how are you liking terraform cloud for state storage? easy?

sweetops avatar
sweetops

well, the initial configuration was super easy. But referencing remote state data/output using the docs, appears to be broken.

Is there a separate channel for tf 0.11 -> 0.12 upgrade woes?

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

haha, just teh #terraform-0_12

We have many interlinked modules that use lots of shared state. We aren’t even sure how to get there from here.

i would move the shared state look ups to to values instead stored in SSM

icky

that would better decouple them from current/future compatibility issues

I feel like Hashicorp let us down by not having remote state compatibility

mrwacky avatar
mrwacky


To provide flexibility when upgrading decomposed environments that use terraform_remote_state, Terraform v0.11.14 introduced support for reading outputs from the Terraform v0.12 state format, so if you upgrade all of your configurations to Terraform v0.11.14 first you can then perform v0.12 upgrades of individual configurations in any order, without breaking terraform_remote_state usage.
Oh, hmm

mrwacky avatar
mrwacky

Maybe we had issues because we didn’t yet have 0.11.14 remote state

mrwacky avatar
mrwacky

maybe a terraform refresh everywhere will save us

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

Oh wow, hope that works!

Erik Osterman (Cloud Posse) avatar

report back…

mrwacky avatar

It works just fine! We apparently were not on 0.11.14 last we tested reading 0.12 remote state.

Hi everyone! I am facing issues while trying to provision each ec2 instance with the below TF connection block:

connection {
    type     = "winrm"
    host     = "${aws_instance.ec2instance.*.private_ip[count.index]}"
    user     = "${var.username}"
    password = "${var.admin_password}"
    timeout  = "${var.timeout_tf}"
  }

The issue is with host = "${aws_instance.ec2instance.*.private_ip[count.index]}" line. I have tried all the below modifications however still get the same error message Error: Cycle: aws_instance.ec2instance[1], aws_instance.ec2instance[0]

  1. host = "${aws_instance.ec2instance.*.private_ip}"
  2. host = "${ element(aws_instance.ec2instance.*.private_ip, count.index) }"
  3. host = "${aws_instance.ec2instance.*.private_ip[count.index]}"

Any pointers will be greatly appreciated.

ruan.arcega avatar

hi andy, in you case, i think this code can be useful, please try it:

variable "count" {
  default = 2
}

connection {
    count   = "${var.count}"
    type     = "winrm"
    host     = "${element(aws_instance.ec2instance.*.private_ip, count.index)}"
    user     = "${var.username}"
    password = "${var.admin_password}"
    timeout  = "${var.timeout_tf}"
  }
Andy avatar

Sure, trying now.

:--1:1
Andy avatar

It turns out you cannot use count = "${var.count}" under connection block and it seems I had tried this in #2 of my original post.

Andy avatar

Thanks for assisting. I belive there’s something wrong with the splat syntax I am using..

Andy avatar

Any other pointers ?

ruan.arcega avatar
ruan.arcega

i am thinking…for now i dont know whats going on… if you set ${element(aws_instance.ec2instance.*.private_ip, count.index +1)} i dont know whether it will works

Andy avatar

NP, let me quickly try that.

Andy avatar

Still the same error message.

ruan.arcega avatar
ruan.arcega

if you do not specify the host in the connection block, does it work? because you are inside the loop when you call on provider remote-exec

Andy avatar

Dint actaully try that.. let me try it quickly.

Attributes of other resources
The syntax is TYPE.NAME.ATTRIBUTE. For example, ${aws_instance.web.id} will interpolate the ID attribute from the aws_instance resource named web. If the resource has a count attribute set, you can access individual attributes with a zero-based index, such as ${aws_instance.web.0.id}. You can also use the splat syntax to get a list of all the attributes: ${aws_instance.web.*.id}.
Andy avatar

This is from the official documentation and that’s what we are trying.

Andy avatar
Interpolation Syntax - 0.11 Configuration Language - Terraform by HashiCorp

Embedded within strings in Terraform, whether you’re using the Terraform syntax or JSON syntax, you can interpolate other values into strings. These interpolations are wrapped in ${}, such as ${var.foo}.

Andy avatar

I mean the splat syntax mentioned in the last line.

ruan.arcega avatar
ruan.arcega

i got it…but looks like ok … check it https://www.terraform.io/docs/provisioners/null_resource.html

Provisioners Without a Resource - Terraform by HashiCorp

The null_resource is a resource allows you to configure provisioners that are not directly associated with a single existing resource.

Andy avatar

Yep, will try in a few and update.

Andy avatar

Strangely enough, The same connection block seems to work with null resource but not with the ec2 resource.

ruan.arcega avatar
ruan.arcega

yep, stranger things happens here

ruan.arcega avatar
ruan.arcega

@Andy did u find some way to resolve the issue?

Andy avatar

Hi Ruan, yep, I was able to resolve this issue few minutes back. The trick was to just use self attribute and it would automatically loop over the count. Here’s the snippet which works:

connection {
    type     = "winrm"
    host     = "${self.private_ip}"
    user     = "${var.username}"
    password = "${var.admin_password}"
    timeout  = "${var.timeout_tf}"
  }

owoww!!! nice!!! thanks for share!

Andy avatar

Additional information: I have the count set to 2. From the above point#1, If I put in host = “${aws_instance.ec2instance.1.private_ip}”, It does not give me the error message however doesnt provision both the instances. Just provisions the instance with count.index=1.

Hi guys

I used your terraform-aws-tfstate-backend repo to create remote backend for my tf project. I went ahead and created two separate repos which are deploying using this remote backend (using same s3 bucket and same dynamodb table but different file name). I am getting following error:

Error locking state: Error acquiring the state lock: ConditionalCheckFailedException: The conditional request failed
	status code: 400, request id: {some-lock-value}

followed by tf basic state lock error:

Terraform acquires a state lock to protect the state from being written
by multiple users at the same time. Please resolve the issue above and try
again. For most commands, you can disable locking with the "-lock=false"
flag, but this is not recommended.

Can I not use same s3 bucket and dynamodb table for two different projects? I thought this should be fine because I am using different file names so a different lock will be created for each tfstate file.

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

yes, you can definitely use the same bucket for multiple projects.

Erik Osterman (Cloud Posse) avatar
Erik Osterman (Cloud Posse)
terraform {
  backend "s3" {

    key    = "path/to/my/project"
    region = "us-east-1"
  }
}
Erik Osterman (Cloud Posse) avatar

just make sure you vary the key

Hi, I.m using: https://github.com/cloudposse/terraform-aws-ec2-autoscale-group but I need my instances to have a 500GB root volume and I’m guessing that can’t be specify ? but in this modeule : https://github.com/cloudposse/terraform-aws-ec2-instance it can, can somehow use both ?

sarkis avatar
sarkis

@PePe you can attach extra drives with block device mapping, however I don’t think the launch template gives you the option for root disk size: https://www.terraform.io/docs/providers/aws/r/launch_template.html

Unsure off top of my head if that is a TF limitation or AWS one. So your only option if you want autoscaling may be to modify the AMI.

AWS: aws_launch_template - Terraform by HashiCorp

Provides an EC2 launch template resource. Can be used to create instances or auto scaling groups.

PePe avatar

that that will anything but the root

PePe avatar

this is a ECS instance

PePe avatar

I will have to change the ECS agent config so docker images are store in a different volume

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

root is specified by the AMI

PePe avatar

I was hoping I will have the option like when you do it in the console when it gives you the option for a bigger root volume

sarkis avatar
sarkis

@PePe do you have that option when creating an EC2 instance or launch template?

PePe avatar

when creating an Instance

sarkis avatar
sarkis

Yea this is why it’s available in aws-ec2-instance module and not in launch template/asg one. Only option if using latter is to modify your AMI to the 500gb volume

PePe avatar

I was using a ECS optimized instance

PePe avatar

I thought I could just define the size of the root volume

PePe avatar

I guess when you use the wizard and change the root volume size it creates a new AMI ID

PePe avatar

since the original AMI can’t be modified

Does anyone know a good repository/tutorial to create a php lambda layer with terraform?

hello I’m using : https://github.com/cloudposse/terraform-aws-ecs-alb-service-task and I was trying to do this :

volumes = [
    {

      host_path = "/mnt/pepe.ramdisk"
    },
    {
      name      = "pepe-incrementals"
      docker_volume_configuration {
        scope         = "task"
        driver = "local"
      }
    }
  ]
}

but I get

 module.ecs_alb_service_task.aws_ecs_task_definition.default: volume.1.docker_volume_configuration: should be a list
PePe avatar

I thought that was going to work….

Andriy Knysh (Cloud Posse) avatar

in TF 0.11 (with its loose/weak typing), mostly all blocks are lists, although it’s not clear from the docs

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

use list, [aws_security_group.gitlab_alb.id]

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

same for subnets subnets = [var.public_subnet_id]

Abhi avatar

Gotcha, I thought they updated this that it should work without using []

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

if the input vars are lists, then you don’t need to wrap them in []

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

aws_security_group.gitlab_alb.id is not a list, it’s a string, so you need []

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

if var.public_subnet_id is a list (which by its name looks like just a string), then you don’t need []

makes sense, thank you very much!

@s2504s no, not name tag

custom tags used for various purposes

i removed some redundant tags from default map and it now forces a new launch template creation

loren avatar
loren

don’t the tags pass thru to the instances, not really the template? and you can’t modify a template just replace it, right? so i don’t think the ask is possible

rohit avatar
rohit

but it is also possible that it can create a new version of the launch template

Hi everyone, I’m looking for a good example to set defaults for complex variable types.

    query_string            = bool
    cookies_forward         = string
    headers                 = list(string)
    query_string_cache_keys = list(string)
    whitelisted_names       = list(string)
    viewer_protocol_policy  = string
    min_ttl                 = number

Terraform Puppet Provisioner attachment image

HashiCorp Terraform 0.12.2 added official support for a Puppet provisioner. One caveat is that the provisioner is only available in 0.12.x of Terraform. The provisioner provides a number of feature…

how do people normally deal with security groups here? the ec2 modules only wants a list of them… do you create flat definitions for each purpose, do you make modules for it?

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

we usually create a security group per module with all the required configurations (especially for backing services like RDS, Elasticsearch, Redis, etc.)

Terraform module to provision an Elasticsearch cluster with built-in integrations with Kibana and Logstash. - cloudposse/terraform-aws-elasticsearch

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

then we specify a list of other security groups and CIDR blocks as ingresses to allow to access the service

PePe avatar

I was looking at this : https://github.com/cloudposse/terraform-aws-ssm-parameter-store/blob/master/example/main.tf and is mention in the doc that this works great with Chamber but if a parameter is on terraform and then I use chamber to create a new one then the state file will be out of sync so what will be the recommended way to do it ? just use chamber from the beginning and not declare anything in terraform ?

cloudposse/terraform-aws-ssm-parameter-store

Terraform module to populate AWS Systems Manager (SSM) Parameter Store with values from Terraform. Works great with Chamber. - cloudposse/terraform-aws-ssm-parameter-store

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

we use that in a few ways. For example, when creating an RDS cluster, we can generate a database username and password and write them to SSM using the module

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

then from a CI/CD pipeline, when we build and start the app, we use chamber to read the username and password from SSM and provide it as ENVs to the app

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

we can manually write some secrets to SSM using chamber, but it’s not related to TF state

PePe avatar

I c ok

PePe avatar

I have some configs for apps that are going to be running now on ECS so we were thinking to use chamber in a script to write the config keys to parameter store

PePe avatar

but I was confused about some examples were segments of config parameter were created using terraform

PePe avatar

I don’t want dev to have to run terraform for config changes

PePe avatar

and just to make this more confusing , please correct me if I’m wrong : SSM parameter Store uses KMS to encrypt the Secrets and store them in AWS secrets ?

PePe avatar

or a parameter store secure string = aws secret encrypted string ?

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

yes, you can specify SecureString and kms_key_id to encrypt

PePe avatar

it is soooo confusing

I seeee ok…

PePe avatar

and have you guys played around with credential rotation for RDS ?

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

do you mean KMS key rotation?

PePe avatar

no the db password rotation

Rotate Amazon RDS database credentials automatically with AWS Secrets Manager | Amazon Web Services attachment image

Recently, we launched AWS Secrets Manager, a service that makes it easier to rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle. You can configure Secrets Manager to rotate secrets automatically, which can help you meet your security and compliance needs. Secrets Manager offers built-in integrations for MySQL, PostgreSQL, and […]

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

i don’t remember we played with that. maybe @Erik Osterman (Cloud Posse) has more inputs

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

we are not using secrets manager right now. for RDS I would instead use the IAM authentation with automatic rotation.

PePe avatar

ohhhh interesting ok I will look into that

PePe avatar

and is there an advantage on using Secret Manager over SSM parameter store SecureString+KMS encrypt ?

PePe avatar

they seem to me very similar offerings

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

As I remember, secret manager is more expensive and does rate limiting

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

And we started using SSM even before secret manager was introduced

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

For some applications it’s better if cost is not an issue

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

secrets manager provides a formal way to use lambdas to rotate secrets according to custom business logic

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

a lot of work needs to go into defining those rotation strategies.

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

plus applications need to be updated to use it.

PePe avatar

exactly

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

RDS IAM authentication also requires application code changes and we’ve noticed a lack of examples (e.g. can’t find a single one for ruby)

How do you guys deploy ECS tasks/images ? using terraform and push new task def ?

Copying this from general channel! Hi guys, I am using your ssh-key-gen module for generating ssh key pair via terraform (https://github.com/cloudposse/terraform-aws-key-pair). I keep was following through the example in readme, however I keep getting permission denied error for creating secrets directory.

Error: mkdir /secrets: permission denied

  on .terraform/modules/test.ssh_key_pair/main.tf line 45, in resource "local_file" "public_key_openssh":
  45: resource "local_file" "public_key_openssh" {

Error: mkdir /secrets: permission denied

  on .terraform/modules/test.ssh_key_pair/main.tf line 52, in resource "local_file" "private_key_pem":
  52: resource "local_file" "private_key_pem" {

Can someone help me out and suggest me what needs to be updated?

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

the user you are running under does not have permissions to folder /secrets

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

try to change the folder to ./secrets

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

or change the user

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

or give it the required permissions

Abhi avatar

cool, I will try it out. Another dumb question, user in this case is my machine’s root user which is running terraform job and seems to have all the permission. This folder is created locally in project repo, is that correct?

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

/secrets is not under project, it’s in root folder

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

./secrets is local folder

Abhi avatar

great, that worked

Abhi avatar

Thanks @Andriy Knysh (Cloud Posse) One more question though, how do you intend to get pem key when running terraform job from CI say something like CircleCI? Push it via artifact to some location from where you can get it?

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

yes, you can write it to S3 or SSM param store or Secret Manager, for example, using terraform

@Erik Osterman (Cloud Posse) quick patch to the deployment controller work: https://github.com/cloudposse/terraform-aws-ecs-alb-service-task/pull/29.

It doesn’t work unless you have ignore changes on since the resources is duplicated. I completely missed that.

Add deployment_controller to ignored service by johncblandii · Pull Request #29 · cloudposse/terraform-aws-ecs-alb-service-task

#28 added the controller to only one of the services. The service is duplicated so it isn’t applying in all scenarios. @aknysh @osterman

is it possible to add a service task on that module that is arbitrary ? like for a blue green ?

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

I’m doing blue/green right now

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

i can show you my approach after this

PePe avatar

if blue_green = “enabled” and blue_green_port = “something” do x

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

I also know that @LeoGmad is doing it

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

yeah

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

we wrap this module so we just attached our stuff in our own module

PePe avatar

I forked the module because of that

PePe avatar

mmm I see

PePe avatar

show me when you can , I’m very interested

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

gimme a sec. i’ll add bits here

PePe avatar

my problem is that I can’t use the standard port

PePe avatar

same problem with the alb module

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

yeah. i just added a new lb listener with port 8443 (vs 443)

PePe avatar

since only creates http and https target groups

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

yeah, i just added new ones

PePe avatar

what I was thinking to do is to create a Target group module

PePe avatar

that is added to the alb module and where you can define arbitrary target group or defaults in no custom ones are defined

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

(leaving parts out for brevity)

module "alb_service_task" {
  source = "git::<https://github.com/cloudposse/terraform-aws-ecs-alb-service-task.git?ref=tags/0.13.0>"
}

module "alb_ingress" {
  source = "git::<https://github.com/cloudposse/terraform-aws-alb-ingress.git?ref=tags/0.7.0>"
}

module "alb_ingress_green" {
  source = "git::<https://github.com/cloudposse/terraform-aws-alb-ingress.git?ref=tags/0.7.0>"
}

resource "aws_lb_listener" "green" {
  load_balancer_arn = "${var.alb_arn}"

  port            = "${var.alb_ingress_port_green}"
  protocol        = "${coalesce(var.alb_ingress_protocol_green, var.alb_ingress_protocol)}"
  ssl_policy      = "${var.ssl_policy}"
  certificate_arn = "${var.certificate_arn}"

  default_action {
    target_group_arn = "${module.alb_ingress_green.target_group_arn}"
    type             = "forward"
  }
}
PePe avatar

and the same thing with the task

PePe avatar
default_action {
    target_group_arn = "${module.alb_ingress_green.target_group_arn}"
    type             = "forward"
  }

is that TF 0.11 compatible ?

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

yup

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

this is all 0.11; we’re migrating to .12 now, but none of that is active

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

do you have your code deploy bits worked out?

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

0.13.1 works, @Erik Osterman (Cloud Posse):

      deployment_controller.0.type:                                                                                     "ECS" => "CODE_DEPLOY" (forces new resource)
PePe avatar

yes code deploy is all good

PePe avatar

I used it for Fargate but is almost the same

PePe avatar

what do you need ?

johncblandii (Cloud Posse) avatar

PePe avatar

how are you going to do the route traffic thing in Code deploy

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

manual

PePe avatar

did you do a script to do the API call ?

PePe avatar

ohh I see

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

but it is configurable w/ timeouts

PePe avatar

we have not decided on that

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

we technically haven’t either so using manual for now.

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

it demo’s better.

PePe avatar

PePe avatar

run some test and then do it

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

nice

johncblandii (Cloud Posse) avatar
johncblandii (Cloud Posse)

how’d you do your aws_codedeploy_deployment_group, @PePe? specifically the lb section:

  load_balancer_info {
    target_group_pair_info {
      prod_traffic_route {
        listener_arns = ["${module.alb.https_listener_arn}"]
      }

      target_group {
        name = "${module.main_container.alb_target_group_name}"
      }

      test_traffic_route {
        listener_arns = ["${module.main_container.alb_green_listener_arn}"]

I’m planning to use terraform-aws-route53-cluster-zoneto create Route53 hosted zones, and I have a question regarding the creation of the parent zone. Can I use this module to create a parent zone resource in Route53?

Erik Osterman (Cloud Posse)

I don’t think this module handles that use-case.

Erik Osterman (Cloud Posse) avatar

Actually, we don’t have a module for the TLD; I guess since we mostly register the zone via Route53 which creates them for us.

hmm, thought so but I’m getting asked for username/password when terraform init using .envrc even though I have SSH agent loaded

Erik Osterman (Cloud Posse) avatar

oh, then you are probably not using a git ssh url

Erik Osterman (Cloud Posse) avatar

lol everyones either windows or mac here; WSL can be a colossal D at times. I’ve had issues with the terraform plugin cache folder in recent weeks; but thats relocatable ENV TF_PLUGIN_CACHE_DIR=/tmp I have to set ENV ASSUME_ROLE_INTERACTIVE=false as assume-role fails to work in the new format.

aws-vault works fine though and the rest seems ok. Obviously if you want to utilise the /localhost thing it isn’t mapping to c:\users\user its mapping to c:\users\user\appdata.… etc… wsl path (it kindly pumps that out when it boots so you can tell where its mapped)

Does anyone has an idea how I can make this snippet Terraform 0.11 code (which is part of a module) compatible with Terraform 0.12 so the module can already be used in a Terraform 0.12 context

data "aws_ami" "instance" {
  most_recent = true

  filter = "${var.runner_ami_filter}"

  owners = "${var.runner_ami_owners}"
}


variable "ami_filter" {
  type        = "list"

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

The problem is the way I pass the block as list of a map is not supported by TF 0.12

loren avatar
loren

IF it is still a block:

variable "ami_filter" {
  type        = "list"

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

OR if they changed default to be a map:

variable "ami_filter" {
  type        = "list"

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

oh silly me, i see what you’re doing, that’s a variable def

niek avatar

Yepz, and a hack

niek avatar

I would give the user the option to define the filter in a flexible way

loren avatar
loren
variable "ami_filter" {
  type        = list(map())

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

change the type

niek avatar

you can’t keep this stuff backwards compatible

basically have to uplift everything to 0.12 somehow

either maintain multiple branches/versions, or just make a hard stop on 0.11 support

Is anyone familiar with queueing apply’s on all workspaces in TFE through an API call? Trying to figure out how to dynamically integrate the CI/CD pipeline that’s generating ECR images and lambda packages, into ECS task definitions and lambda functions. The trouble I’ve run into though is you can only queue up an apply call on an individual workspace, which means you need a list of them, which defeats dynamic-ism and the self-service nature of terraform

@PePe you can use a self made lambda datasource as workaround

PePe avatar

how ?

maarten avatar
maarten

so in your terraform run you apply the lambda and subsequently use aws_lambda_invocation for a lookup of a value.

PePe avatar

so you are using the lambda as some sort of key:value store

maarten avatar
maarten

no the lambda is used as a datasource. It’s doing the same kind of lookup a regular datasource would normally do but it won’t fail the moment the actual resource is not existing yet.

Does anyone know if default block reuse through “locals” still works in 0.12? I’m getting consistent errors in 0.12 that I didn’t get in 0.11 like “An argument named “health_check” is not expected here. Did you mean to define a block of type “health_check”?”

Vasco Pinho avatar
Vasco Pinho

Specifically I was using similar syntax to this but for health_checks instead of tags https://www.terraform.io/docs/configuration/locals.html

Local Values - Configuration Language - Terraform by HashiCorp

Local values assign a name to an expression that can then be used multiple times within a module.

loren avatar
loren

that sounds like the error where tf 0.12 differentiates strongly between attrs (assigned using =) and blocks (no assignment), i.e.

attr = { foo = "bar" }
block {
  foo = "bar"
}
loren avatar
loren

tf 0.11 let you do either in many/most places, tf 0.12 forces you to use the syntax that matches the implementation

Vasco Pinho avatar
Vasco Pinho
01:34:31 PM
Vasco Pinho avatar
Vasco Pinho

So this works

Vasco Pinho avatar
Vasco Pinho

but if you use the same syntax for healthcheck’s, since you want to keep it DRY, it fails with the error above

Vasco Pinho avatar
Vasco Pinho

Did TF 0.12 do some special grant for “tags” blocks?

loren avatar
loren

yes, tags are no longer blocks, they are attrs

loren avatar
loren

to make blocks DRY, you probably want to investigate dynamic blocks, https://www.terraform.io/docs/configuration/expressions.html#dynamic-blocks

Expressions - Configuration Language - Terraform by HashiCorp

The Terraform language allows the use of expressions to access data exported by resources and to transform and combine that data to produce other values.

Vasco Pinho avatar
Vasco Pinho

Mmm I’ll take a look at those, thanks for the pointers @loren

Vasco Pinho avatar
Vasco Pinho

The syntax is now expecting a for-loop as a base for it, instead of simple substitution using a “local” block. Even if I faked the for-loop it seems like I’d still need to repeat myself for all keys in the “content” section in all resources vs just referencing the local. Still trying to figure out if there’s any good way of doing this or if I just have to go back to repeating it in all resource blocks

Andriy Knysh (Cloud Posse) avatar
Andriy Knysh (Cloud Posse)

@Vasco Pinho you will also get the same (or similar) error message when using dynamic block with for loop on a list variable without updating the type of the variable to list(object) and specifying the types of items in the list. For example:

Vasco Pinho avatar
Vasco Pinho

Yeah the point here was to have a short concise file, which we did in 0.11 because the healthcheck block (which was the same for most resources) got interpolated. I just undid all of that for 0.12 and now it works. Oh well.
