I am implementing a batch in Azure Container Apps.
When a message comes from a queue in service bus then my batch is run.
For this, I added a scale rule to automatic scale when a message comes from the queue.
It works well, when there is a message it is scaled out from 0 to 1 replica. But when my batch is terminated, the replica restarts the container several times until it is scaled in to 0.
Here is my terraform script to create the container apps :
resource "azapi_resource" "container_app" {
name = var.container_app_name
location = "northeurope"
parent_id = data.azurerm_resource_group.resource_group.id
identity {
type = "UserAssigned"
identity_ids = [data.azurerm_user_assigned_identity.aca_identity.id]
}
type = "Microsoft.App/containerApps#2022-03-01"
body = jsonencode({
properties: {
managedEnvironmentId = data.azapi_resource.container_environment.id
configuration = {
secrets = [
{
name = "regitry-password"
value = data.azurerm_container_registry.acr.admin_password
},
{
name = "service-bus-connection-string"
value = data.azurerm_servicebus_namespace.servicebus.default_primary_connection_string
}
]
ingress = null
registries = [
{
server = data.azurerm_container_registry.acr.login_server
username = data.azurerm_container_registry.acr.admin_username,
passwordSecretRef = "regitry-password"
}]
}
template = {
containers = [{
image = "${data.azurerm_container_registry.acr.login_server}/${var.container_repository}:${var.container_image_tag}"
name = "dbt-instance"
resources = {
cpu = var.container_cpu

}
]
}]

How to run my container only one time ?
I managed to do it with Azure Container Instance with the property "restartPolicy=Never"
I am having difficulties with defining a variable inside the ami=data.aws_ami.$var.ami_name.id line.
I have tried ami= "${data.aws_ami.(var.ami_name).id}"but in both cases I am getting the:
79: ami = data.aws_ami.(var.ami_name)).id
│
│ An attribute name is required after a dot.
It only works with the string value data.aws_ami.ubuntu-1804.id.
My question is how to concat the variable to the data.aws_ami?
The end goal is to provision based on different OS ec2 instances (Suse,Ubuntu,RHEL) All depending on the variable provided when deploying it.
variable "ami_name" {
default = "ubuntu"
}
data "aws_ami" "amazon" {
most_recent = true
owners = ["amazon"]
filter {
name = "name"
values = ["amzn2-ami-hvm*"]
}
}
data "aws_ami" "ubuntu" {
most_recent = true
owners = ["099720109477"] # Canonical
filter {
name = "name"
values = ["ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-*"]
}
filter {
name = "virtualization-type"
values = ["hvm"]
}
}
resource "aws_instance" "linux" {
key_name = var.ami_key_pair_name
//ami = var.ami_id
//I want this to be dynamic so I can deploy either Amazon or Ubuntu in all regions.
ami = data.aws_ami.$var.ami_name.id
//ami = data.aws_ami.ubuntu.id # this works
instance_type = "t2.micro"
tags = {
Name = var.instance_name
}
vpc_security_group_ids = [
aws_security_group.allow-ssh-http.id
]
}
I did the search but could not find anything related. I am using Terraform v0.15.4
The code you show: data.aws_ami.$var.ami_name.id that is not valid terraform syntax.
Here is a possibility for what you are asking:
provider "aws" { region = "us-east-2" }
locals {
allowed_os = {
"amazon": {owner: "amazon", filter: "amzn2-ami-hvm*"},
"suse": {owner: "amazon", filter: "*suse*"},
"RHEL": {owner: "amazon", filter: "*RHEL*"},
"ubuntu": {owner: "099720109477", filter: "*ubuntu-bionic-18.04-amd64-*"},
}
}
variable "ami_name" {
default = "ubuntu"
validation {
condition = can(regex("amazon|suse|RHEL|ubuntu", var.ami_name))
error_message = "Invalid ami name, allowed_values = [amazon suse RHEL ubuntu]."
}
}
data "aws_ami" "os" {
for_each = local.allowed_os
most_recent = true
owners = [each.value.owner]
filter {
name = "name"
values = [each.value.filter]
}
}
resource "aws_instance" "linux" {
ami = data.aws_ami.os[var.ami_name].id
instance_type = "t2.micro"
# ... todo add arguments here
}
My approach here is to use a for_each in the aws_ami, that will give us an array, we can consume that later in the aws_instance resource:
data.aws_ami.os["ubuntu"].id
Here we use a hardcoded value to access a specific AMI in your code.
data.aws_ami.os[var.ami_name].id
Or this way with the variable that will be provided by user or a config file.
You can add more items to the array to add other operating systems, and same with the filters, you can just change the allowed_os local variable to suit your needs.
As an extra, I added validation to your ami_name variable to match the allowed different OS we use in the for_each, that way we prevent any issues right before they can cause errors.
I have variable that I want to iterate over using for_each in terraform to create multiple instances of submodule - node_groups, which is part of eks module. This is my variable:
variable "frame_platform_eks_node_groups" {
type = map
default = {
eks_kube_system = {
desired_capacity = 1,
max_capacity = 5,
min_capacity = 1,
instance_type = ["m5.large"],
k8s_label = "eks_kube_system",
additional_tags = "eks_kube_system_node"
},
eks_jenkins_build = {
desired_capacity = 1,
max_capacity = 10,
min_capacity = 1,
instance_type = ["m5.large"],
k8s_label = "eks_jenkins_build",
additional_tags = "eks_jenkins_build_node"
}
}
}
And this is my node_groups submodule, which is part of module eks.
module "eks" {
...
node_groups = {
for_each = var.frame_platform_eks_node_groups
each.key = {
desired_capacity = each.value.desired_capacity
max_capacity = each.value.max_capacity
min_capacity = each.value.min_capacity
instance_types = each.value.instance_type
k8s_labels = {
Name = each.value.k8s_label
}
additional_tags = {
ExtraTag = each.value.additional_tags
}
}
When I run terraform plan I am getting following error:
15: each.key = {
If this expression is intended to be a reference, wrap it in parentheses. If
it’s instead intended as a literal name containing periods, wrap it in quotes
to create a string literal.
My intention obviously is to get eks_kube_system and eks_jenkins_build values from the map variable with each.key reference. But something is wrong. Do you have advice what I am doing wrong?
Thank you!
Its not exactly clear what node_groups is as it is not defined in your question, but assuming that it is a list of maps, then the code should be:
module "eks" {
...
node_groups = [
for k,v in var.frame_platform_eks_node_groups:
{
desired_capacity = v.desired_capacity
max_capacity = v.max_capacity
min_capacity = v.min_capacity
instance_types = v.instance_type
k8s_labels = {
Name = v.k8s_label
}
additional_tags = {
ExtraTag = v.additional_tags
}
}
]
I have a complex data structure and I had to create this short example for better understanding.
type alias People =
{ name : String
, sex : String
, phones : List Phone
}
type alias Phone =
{ number : String
, isActive : Bool
}
This structure populated:
people = [
{ name = "_me"
, sex = "M"
, phones = [
{ number = "(99) 99 9 9999-9999"
, isActive = True
}]
},
{ name = "_you"
, sex = "M"
, phones = [
{ number = "(11) 11 1 1111-1111"
, isActive = True
},
{ number = "(22) 22 2 2222-2222"
, isActive = False
}]
}]
And I would like to get only the 'phones' from the 'people' list, as in the example below
phones = [
{ number = "(99) 99 9 9999-9999"
, isActive = True
},
{ number = "(11) 11 1 1111-1111"
, isActive = True
},
{ number = "(22) 22 2 2222-2222"
, isActive = False
}]
I've been trying for 3 days, but to no avail.
You can pull out all the phone numbers into a list by mapping over to get the phone number list of a person, then concatenating those phone number lists together:
getPhones : List People -> List Phone
getPhones = List.concat << List.map .phones
i have the following type User:
type alias User =
{ id : Int
, name : String
, age : Maybe Int
, deleted : Bool
}
User is a type used in my Model:
type alias Model =
{ users : List User
, name : String
, age : String
, message : String
}
When I iterate over "List User" using List.map like this...
Delete id ->
let
newUserList =
List.map
(\user ->
if user.id == id then
{ user | deleted = True }
else
user
)
model.users
in
( { model | users = newUserList }, Cmd.none )
... the Compiler tells me:
The 2nd argument to function `map` is causing a mismatch.
List.map
(\user ->
if user.id == id then
{ user | deleted = True }
else
user
)
model.users
Function `map` is expecting the 2nd argument to be:
List { a | id : Int, name : String }
But it is:
List (Bool -> User)
That is pretty strange for me.
Why does my map function change the Type User...?
I do not change it, I just iterate over, map each user and if I found the right one, by its id, I change deleted value to True...
I am a bit confused...
Can anyone help?
kind regards :)
UPDATE: It does not seem to me a problem of the List.map function but of the type alias User declaration.
As soon as I add another value this breaks...
Here is the whole code for it. It is kept pretty simple.
Note: As soon as you uncomment the Users property "deleted" the compiler throws an error

The problem is this part of the AddNewUser message:
newUser =
User randomId model.name ageAsInt
It is missing False as the forth argument when you use the deleted property.
If you do not include it, the User function will return a partially applied function that still needs a Bool to return a proper user. The compiler seems to get thrown off by this even though all your types and functions have proper annotations.
Another way that leads to a better error message would be to define newUser like this:
newUser =
{ id = randomId
, name = model.name
, age = ageAsInt
, deleted = False
}
