I am trying to create a ServiceAccount that has restricted access to invoke a single cloud function.
resource "google_service_account" "service_account" {
account_id = "service-account-id"
display_name = "Service Account"
}
data "google_iam_policy" "invoker" {
binding {
role = "roles/cloudfunctions.invoker"
members = [
"serviceAccount:${google_service_account.service_account.email}",
]
condition {
expression = "resource.name == projects/project_name/locations/region/functions/function_name"
title = foo
}
}
}
resource "google_cloudfunctions2_function_iam_policy" "binding" {
cloud_function = "projects/project_name/locations/region/functions/function_name"
project = var.common.project_id
location = var.common.default_region
policy_data = data.google_iam_policy.invoker.policy_data
}
However when I apply this change I get an error.
module.handler-build.google_cloudfunctions2_function_iam_policy.binding: Creating...
╷
│ Error: Error setting IAM policy for cloudfunctions2 function "projects/project_name/locations/region/functions/function_name": googleapi: Error 400: Invalid argument: 'An invalid argument was specified. Please check the fields and try again.'
I would try to call google_cloudfunctions2_function_iam_binding or google_cloudfunctions2_function_iam_member but they don't have condition expression that I can use. It is important to add the condition so this service account cannot call other cloud functions.
How can I add invoker policy to the service account?

I'm trying to create an alert policy with Cloud Functions in python. I have the following very simple alert policy:
alert_policy = {
'combiner': 'OR',
'conditions': [
{
'conditionAbsent': {
'duration': '3900s',
'filter': 'resource.type = "l7_lb_rule" AND metric.type = "logging.googleapis.com/user/name_stuff_here"'
}
}
]
}
When running the function I have the following error: Protocol message Condition has no "conditionAbsent" field error
How should I write this alert Policy? I also had some error because of Displayname field which I've removed entirely. Is there an alert policy builder or something like that where I can validate alerts json?
Looking more closely at the documentation I found that conditionAbsent should be passed as condition_absent
This question already has an answer here:
Gmail AppScript mailMessage.getFrom() to return email not name
(1 answer)
Closed 2 years ago.
I have developed a Gmail add-on.
In that I will get the list of emails in from, to, cc and bcc with the help of GmailMessage class.
like for from email , GmailMessage.getFrom()
for to email, GmailMessage.getTo()
In the documentation it is stated that it will return an email as string but it is not clearly mentioned anywhere about the format of that string.
Sometimes I'm getting in the format of Name of the account<accountEmail#gmail.com>
and sometimes in the format of <accountEmail#gmail.com> and sometimes only name will be available without the email ID of the recepient.
Sometimes it also includes double quotes on the email like Name of the account<"accountEmail#gmail.com">
Can someone tell is there a way to get the exact email address and name separately from Gmail using Google apps script?
Or suggest some ways to parse the email from GmailMessage class and get email address and name separately
I found the the gmail api site (here) which might come in use if you end up using the code. Although the code is in python so it might not work on google app script, but the only reason to use google apps script is to achieve these results. You also are going to have to know what you are doing when using this(if you want to use google app script, try making a gmail app template then go here to learn the basics (here) and here for further documentation (here))

I'm using terraform to set up an app on heroku. The app needs a mysql database and I'm using ClearDB addon for that. When ClearDB is attached to the app, it sets a CLEARDB_DATABASE_URL config variable. The app requires the database url to be in a DATABASE_URL config variable.
So what I'm trying to do is to use resource heroku_app_config_association to copy the
value from CLEARDB_DATABASE_URL to DATABASE_URL. The problem is that after heroku_app resource is created, its state does not yet contain CLEARDB_DATABASE_URL, and after heroku_addon is created, the state of heroku_app is not updated.
This is the content of my main.tf file:
provider "heroku" {}
resource "heroku_app" "main" {
name = var.app_name
region = "eu"
}
resource "heroku_addon" "database" {
app = heroku_app.main.name
plan = "cleardb:punch"
}
resource "heroku_app_config_association" "main" {
app_id = heroku_app.main.id
sensitive_vars = {
DATABASE_URL = heroku_app.main.all_config_vars.CLEARDB_DATABASE_URL
}
depends_on = [
heroku_addon.database
]
}
This is the error that I get:
Error: Missing map element
on main.tf line 22, in resource "heroku_app_config_association" "main":
22: DATABASE_URL = heroku_app.main.all_config_vars.CLEARDB_DATABASE_URL
|----------------
| heroku_app.main.all_config_vars is empty map of string
This map does not have an element with the key "CLEARDB_DATABASE_URL".
The configuration variable is copied successfully when terraform apply is executed second time. Is there a way to make it work on the first run?
To get up-to-date state of the heroku_app resource I used the data source:
data "heroku_app" "main" {
name = heroku_app.main.name
depends_on = [
heroku_addon.database
]
}
I could then access the value in heroku_app_config_association resource:
resource "heroku_app_config_association" "main" {
app_id = heroku_app.main.id
sensitive_vars = {
DATABASE_URL = data.heroku_app.main.config_vars.CLEARDB_DATABASE_URL
}
}
I am currently trying to set up Google Cloud Endpoints on Cloud Run to be able to have an OpenApi Documentation for my Cloud Functions. I followed the instructions in here for a PoC and it worked fine.
Now I have tried to set it up using terraform 0.12.24
Service Endpoint
data "template_file" "openapi_spec" {
template = file("../../cloud_functions/openapi_spec.yaml")
vars = {
endpoint_service = local.service_name
feedback_post_target = google_cloudfunctions_function.feedbackPOST.https_trigger_url
}
}
resource "google_endpoints_service" "api-gateway" {
service_name = local.service_name
project = var.project_id
openapi_config = data.template_file.openapi_spec.rendered
depends_on = [
google_project_service.endpoints,
google_project_service.service-usage,
]
}
Cloud RUN
locals {
service_name = "${var.endpoint_service_name}.endpoints.${var.project_id}.cloud.goog"
}
resource "google_cloud_run_service" "api-management" {
name = "api-gateway-1233"
location = "europe-west1"
template {
spec {
containers {
image = "gcr.io/endpoints-release/endpoints-runtime-serverless:2"
env {
name = "ENDPOINTS_SERVICE_NAME"
value = local.service_name
}
}
}
}
traffic {
percent = 100
latest_revision = true
}
depends_on = [google_project_service.run]
}
If I try to execute my function from the Endpoints portal now, I get the following error
ENOTFOUND: Error resolving domain "https://function-api-gateway.endpoints.PROJECT_ID.cloud.goog"
which makes total sense, as my endpoints service should use the host url of the cloud run service which is given by
google_cloud_run_service.api-management.status[0].url
which means, that I have to use this in the Service endpoints definition above as service name and host-environmental variable in the openApi definition.
Only when this is set, I can again apply my cloud run service with the env variable being its url itself.
This is a circular dependency which I do not know how to solve.
Any help is highly appreciated!
I need to update the api key value using my lambda function.
I looked through API Gateway SDK Documentation and I thought updateApiKey was the best option, but when I send the request, I get an error as return:
BadRequestException: Invalid patch path 'value' specified for op 'replace'. Must be one of: [/description, /enabled, /name, /customerId]
at Object.extractError (/var/task/node_modules/aws-sdk/lib/protocol/json.js:51:27)

at Request.<anonymous> (/var/task/node_modules/aws-sdk/lib/request.js:685:12)
Basically, it is saying that I can't update "value", so I couldn't do what I need
For now, my code is that:
let sendPromise = null;
let params = {
"apiKey": "xxxxxxxxx",
patchOperations: [
{
op: "replace",
path: "value",
value: "teste123"
}
]
};
sendPromise = new AWS.APIGateway().updateApiKey( params ).promise();
try {
const data = await sendPromise;
return criarResposta( 200, `{
"message": "OK"
}` );
} catch (err) {
console.error(err, err.stack);
return criarResposta( 500, err.stack );
}
Is there any other function to update the api key value?
There is no other function to update the api key value. I think this is by design.
I do not know this for sure but there is evidence that AWS designed the apikey resource's value attribute immutable:
The AWS REST api for ApiGateway is the service's endpoint which supports the largest subset of operations available. The attributes which support modification are listed in the REST api documentation: /customerId, /description, /enabled, /labels, /name, /stages. [1]
The AWS Management Console does not support modification of the apikey value either. There is only the option to 'show' the apikey's value.
So if you want to change the value, you have to delete the existing apikey and create a new one. This includes recreating all the usageplankey resources which associate apikey resources with usageplan resources.
