QUESTION
For the project I'm on, I am tasked with creating a testing app that uses Terraform to create a resource instance and then test that it was created properly. The purpose is testing the Terraform Script result by validating certain characteristics of the resource created. That's the broad outline.
For several of these scripts a resource is assigned a role. It could be a PubSub subscription, DataCatalog, etc.
Example Terraform code for a Spanner Database assigning roles/spanner.databaseAdmin:
...ANSWER
Answered 2022-Mar-17 at 16:54Thought I should close this question off with what I eventually discovered. The proper question isn't what role is assigned an instance of a resource, but what users have been allowed to use the resource and with what role.
The proper call is GetIamPolicy which is available in the APIs for all of the resources that I've been working with. The problem was that I wasn't seeing anything due to no user accounts being assigned to the resource. I updated the Terraform script to assign a user to the resource with the required roles. When calling GetIamPolicy, it returns an array in the Bindings that lists roles and users that are assigned. This was the information I needed. Going down the path of using TestIamPermissions was unneeded.
Here's an example my use of this:

Answered 2021-Nov-19 at 00:50When you are using scheduled functions in Firebase Functions, an App Engine instance is created that is needed for Cloud Scheduler to work. You can read about it here. During its setup you're prompted to select your project's default Google Cloud Platform (GCP) resource location (if it wasn't already selected when setting up another service).
You are getting that error because there is a difference between the default GCP resource location you specified and the region of your scheduled Cloud Function. If you click on the cogwheel next to project-overview in Firebase you can see where your resources are located. Setting the default GCP resource location same as the scheduler function region, solves the issue.

We have a data pipeline built in Google Cloud Dataflow that consumes messages from a pubsub topic and streams them into BigQuery. In order to test that it works successfully we have some tests that run in a CI pipeline, these tests post messages onto the pubsub topic and verify that the messages are written to BigQuery successfully.
This is the code that posts to the pubsub topic:

I am using Elixir Desktop to make an elixir desktop application: https://github.com/elixir-desktop/desktop

...ANSWER
Answered 2022-Jan-20 at 15:17At the time of this writing, the author pushed a fix to Master in Github.
This fix addresses the issue of the application taking a long time to close, however it does not address the Chrome_WidgetWin_0. Error issue.
This issue is a known one and has already been reported, but there are no signs of fixing it from the Chrome project, so I guess we just have to live with it for the time being: https://bugs.chromium.org/p/chromium/issues/detail?id=113008
Another issue is the crash. Is likely happens because of the previous issue, and therefore there is little one can do here.
Since the main problem was fixed, I am marking this as solved.

The Terraform document clearly states variable defined in the root module can be set in tfvars file.
The type constructors allow you to specify complex types such as collections:

Assigning Values to Root Module Variables
When variables are declared in the root module of your configuration, they can be set in a number of ways:
- In variable definitions (.tfvars) files, either specified on the command line or automatically loaded.
An input variable of type set can be defined in a root module.

I have a fresh project but was looking to test scheduled functions. Am I missing anything?
...ANSWER
Answered 2021-Nov-20 at 04:06When you are using scheduled functions in Firebase Functions, an App Engine instance is created that is needed for Cloud Scheduler to work. You can read about it here.They use the location that has been set by default for resources. I think that you are getting that error because there is a difference between the default GCP resource location you specified and the region of your scheduled cloud function. If you click on the cogwheel next to project-overview in Firebase you can see where your resources are located.
Check your Cloud Scheduler function details and see which region it has been deployed to. By default, functions run in the us-central1 region. Check this link to see how we can change the region of the function.
QUESTION
Context: I am training a very similar model per bigquery dataset in Google Vertex AI, but I want to have a custom training image for each existing dataset (in Google BigQuery). In that sense, I need to programatically build a custom Docker Image in the container registry on demand. My idea was to have a Google Cloud Function do it, being triggered by PubSub topic with information regarding which dataset I want to build the training container for. So naturally, the function will write the Dockerfile and pertinent scripts to a /tmp folder within Cloud Functions (the only writable place as per my knowledge). However, when I try to actually build the container within this script, apparently, it doesn't find the /tmp folder or its contents, even though they are there (checked with logging operations).
The troubling code so far:

QUESTION
I am trying to create a dataproc cluster that will connect dataproc to pubsub. I need to add multiple jars on cluster creation in the spark.jars flag
...ANSWER
Answered 2021-Nov-27 at 22:40The answer you linked is the correct way to do it: How can I include additional jars when starting a Google DataProc cluster to use with Jupyter notebooks?
If you also post the command you tried with the escaping syntax and the resulting error message then others could more easily verify what you did wrong. It looks like you're specifying an additional spark property in addition to your list of jars spark:spark.driver.memory=3000m, and tried to just space-separate that from your jars flag, which isn't allowed.
Per the linked result, you'd need to use the newly assigned separator character to separate the second spark property:

Install pubsub
You can use pubsub like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the pubsub component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
