How to generate SAS token using Access policy for a folder in container of ADLS gen 2.
exactly like below image but for ADLS gen 2 containers or folders. thank you in advance.
To generate SAS token using Access policy on ADLS containers need to create a Access Policy first . You can create Access Policy through Azure portal (Please Check with this link) or Storage Explorer.
Based on your attached
Screenshot you are using the Microsoft Storage Explorer so here are steps create access policy
1)Go to your container --> right click on container
2)Select the manage access policy
3)Click on the add. There you can provide the Access policy id and permissions you need to give on container like read ,write (click on check boxes).And click on save
4)Once access policy created. You can create the SAS based on that access policy .Right click on
The container select Get Share Access Signature. From the dropdown select the access policy and click
On the create
Generate SAS using terraform
terraform {
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "~> 2.65" }
}
required_version = ">= 0.14.9"
}
provider "azurerm" {
features {}
}
resource "azurerm_resource_group" "rg" {
name = "terraformtest"
location = "West Europe"
}
resource "azurerm_storage_account" "storage" {
name = "storage name"
resource_group_name = azurerm_resource_group.rg.name
location = azurerm_resource_group.rg.location
account_tier = "Standard"
account_replication_type = "GRS"
allow_blob_public_access = true
}
resource "azurerm_storage_container" "container" {
name = "terraformcont"
storage_account_name = azurerm_storage_account.storage.name
container_access_type = "private"
}
data "azurerm_storage_account_blob_container_sas" "example" {
connection_string = azurerm_storage_account.storage.primary_connection_string
container_name = azurerm_storage_container.container.name
https_only = true
start = "Date"
expiry = "Date"permissions {
read = true
add = true
create = false
write = false
delete = true
list = true
}
}
output "sas_url_query_string" {
value = data.azurerm_storage_account_blob_container_sas.example.sas
sensitive = true
}
After running the above command you will get output inside terraform.tfstate

I am trying to add custom validation for the variables in my terraform script for S3 bucket. But i am facing an error that is mentioned as below:
Reference to undeclared input variable
on main.tf line 2, in resource "aws_s3_bucket" "gouth_bucket_1_apr_2021":
2: bucket = var.bucket #"terraform-s3-bucket"
An input variable with the name "bucket" has not been declared. This variable
can be declared with a variable "bucket" {} block."
Can anyone help me on the same.please let me know which file needs the necessary changes and how.
Thanks in Advance
Below is my code :
main.tf :
resource "aws_s3_bucket" "gouth_bucket_1_apr_2021" {
bucket = var.bucket
acl = "private"
tags= var.tags
}
s3.tfvars :
bucket = "first-bucket-gouth"
#Variables of Tags
tags= {
name = "s3bucket",
account_id = "1234567",
owner = "abc#def.com",
os= "windows",
backup = "N",
application = "abc",
description = "s3 bucket",
env = "dev",
ticketid = "101",
marketami = "NA",
patching = "NA",
dc = "bangalore"
}
validation.tf :
variable "tags" {
type = map(string)
validation {
condition = length(var.tags["env"]) > 0
error_message = "Environment tag is required !!"
}
validation {
condition = length(var.tags["owner"]) > 0
error_message = "Owner tag is required !!"
}
validation {
condition = length(var.tags["dc"]) > 0
error_message = "DC tag is required !!"
}
validation {
condition = can(var.tags["account_id"])
error_message = "Acoount ID tag is required!!"
}
}
I can see two potential issues.
You are referencing var.bucket in your resource, but you are not defining a variable for it anywhere in your definition. This could simply look like:
variable "bucket" {}
You may not be picking up your tfvars file, if you are running Terraform with the tfvars file as an option like so terraform plan -var-file=s3.tfvars then thats ok, or you can rename your tfvars file to something.auto.tfvars or terraform.tfvars to get automatically used. (See > https://www.terraform.io/docs/language/values/variables.html#variable-definitions-tfvars-files)
I hope this answers your question.
With this code, I'm planning on having mulitple variables like "vms". These are key/value maps of VMs and resource groups where I for_each on the data source lookup (backupvm) to get their id. Then I can add these VMs, using id, as a backup item in vault.
data "azurerm_virtual_machine" "backupvm" {
for_each = var.vms
name = each.key
resource_group_name = each.value
}
variable "vms" {
type = map
default = {
# "vm name" = "resource group name"
"vaulttestvm1" = "vaulttestrg"
"vaulttestvm2" = "vaulttestrg"
"vaulttestvm4" = "vaulttestrg"
}
}
resource "azurerm_resource_group" "rg" {
name = var.rg_name
location = var.location
}
resource "azurerm_recovery_services_vault" "vault" {
name = var.vault_name
location = azurerm_resource_group.rg.location
resource_group_name = azurerm_resource_group.rg.name
sku = "Standard"
# change later
soft_delete_enabled = false
}
resource "azurerm_backup_protected_vm" "vms" {
for_each = var.vms
recovery_vault_name = azurerm_recovery_services_vault.vault.name
resource_group_name = azurerm_recovery_services_vault.vault.resource_group_name
source_vm_id = data.azurerm_virtual_machine.backupvm[each.key].id
backup_policy_id = azurerm_backup_policy_vm.VMBackupPolicy.id
}
I need a way to reference var.vms, in both the data source & resource, so I could interchange using some logic for another map type variable. So if it was PowerShell, it would be something like:
name = if ($env -eq "prod") { $var.vms } elseif ($env -eq "stage") { $var.vmsstage } elseif ($env -eq "dev") { $var.vmsdev }
I've spent a day trying different things but haven't really got close. I may be somewhat restricted as I need to lookup the vm id using the data source first then loop through my resource (azurerm_backup_protected_vm) dropping that ID in. A solution to this would prevent me from having to use multiple data sources and resources of the same type. Thanks!
I have the following terraform code snippet where I'm trying to use a self_link in the subnet.network resource that references the title of the network resource.
main.tf
resource "google_compute_network" "demo-vpc-network" {
auto_create_subnetworks = "false"
delete_default_routes_on_create = "false"
name = var.GCP_COMPUTE_NETWORK_NAME
project = var.GCP_PROJECT_NAME
routing_mode = "REGIONAL"
}
resource "google_compute_subnetwork" "demo-subnet" {
ip_cidr_range = "10.200.0.0/24"
name = "kubernetes"
network = google_compute_network.vpc_network.self.link
private_ip_google_access = "false"
project = var.GCP_PROJECT_NAME
region = "us-west1"
}
However, I get the following error.
Error: Reference to undeclared resource
on main.tf line 77, in resource "google_compute_subnetwork" "demo-subnet":
77: network = google_compute_network.vpc_network.self.link
A managed resource "google_compute_network" "vpc_network" has not been
declared in the root module.
google_compute_network.vpc_network.self.link
won't work because google_compute_network.vpc_network doesn't exist.
It's easy to fix because google_compute_network.demo-vpc-network does exist.
Update: Also, as you've noted in your comment self-link (with a hyphen) won't work and needs to be self_link (with an underscore).
Here's the second resource block with the bug fixed:
resource "google_compute_subnetwork" "demo-subnet" {
ip_cidr_range = "10.200.0.0/24"
name = "kubernetes"
network = google_compute_network.demo-vpc-network.self.link
private_ip_google_access = "false"
project = var.GCP_PROJECT_NAME
region = "us-west1"
}
That's because the resource for the main network is:
resource "google_compute_network" "vpc_network"
Then you could set a name for it with the property:
name = demo-vpc-network

I'm running Terraform using VScode editor which uses PowerShell as the default shell and getting the same error when I try to validate it or to run terraform init/plan/apply through VScode, external PowerShell or CMD.

I've encountered this problem myself in several different contexts, and it does have a common solution which is no fun at all: manually typing the code back in...
This resource block seems to be where it runs into problems:

Try copying that back into your editor as is. I cannot see any problematic characters in it, and ironically StackOverflow may have done you a solid and filtered them out. Literally copy/pasting it over the existing block may remedy the situation.
I have seen Terraform examples online with stylish double quotes (which aren't ASCII double quotes and won't work) many times. That may be what you are seeing.
Beyond that, you'd need to push your code to GitHub or similar so I can see the raw bytes for myself.
In the off-chance this helps someone who runs into this error and comes across it on Google, I just thought I would post my situation and how I fixed it.
I have an old demo Terraform infrastructure that I revisited after months and, long story short, I issued this command two days ago and forgot about it:
terraform plan -out=plan.tf
This creates a zip archive of the plan. Upon coming back two days later and running a terraform init, my terminal scrolled garbage and "This character is not used within the language." for about 7 seconds. Due to the .tf extension, terraform was looking at the zip data and promptly pooping its pants.
Through moving individual tf files to a temp directory and checking their validity with terraform init, I found the culprit, deleted it, and functionality was restored.
Be careful when exporting your plan files, folks!
I ran into the same problem and found this page.
I solved the issue and decided to post here.
I opened my plan file in Notepad++ and selected View-Show all symbols.
I removed all the TAB characters and replaced them with spaces.
In my case, the problem was fully resolved by this.
In my case, when I ran into the same problem ("This character is not used within the language"), I found the encoding of the files was UTF-16 (it was a generated file from PS). Changing the file encoding to UTF-8 (as mentioned in this question) solved the issue.
I found I got this most often when I go from Windows to linux. The *.tf file does not like the windows TABs and Line Breaks.
I tried to some of the same tools I use when I have this problem with *.sh, but so far I've resorted to manually cleaning up the lines I've seen in there error.
In my case, the .tf file was generated by the following command terraform show -no-color > my_problematic.tf, and this file's encoding is in "UTF-16 LE BOM", converting it to UTF-8 fixed my issue.
