I have this app that's been running on Google App Engine for a good couple of years. Today I needed to modify its app.yaml file, but when I ran "gcloud app deploy" I got this error:
Updating service [default]...failed.
ERROR: (gcloud.app.deploy) Error Response: [7] Failed to create cloud build: service account "redacted#cloudbuild.gserviceaccount.com" has insufficient permission to execute the build on project "redacted"
It appears that the default service account no longer has the necessary permissions. In fact, it may have been deleted completely, because I don't see it listed under gcloud projects get-iam-policy xxxx. What I see instead is this:
serviceAccount:service-redacted#gcp-sa-cloudbuild.iam.gserviceaccount.com
with a correct-looking role cloudbuild.serviceAgent.
I tried googling any changes related to GAE service accounts but didn't find any useful references. I followed the solution to this question, but it didn't help.
The question is, how do I change the permissions of the service account mentioned in the original error message, or, how do I tell GAE to use another (correct) service account when deploying my app?
According to [this][1] documentation
...To deploy new versions, a member must have the Service Account User (roles/iam.serviceAccountUser) role on the App Engine default service account, and the Cloud Build Editor (roles/cloudbuild.builds.editor) and Cloud Storage Object Admin (roles/storage.objectAdmin) roles on the project.....
Using the IAM page you can add the email address of the person deploying (the one you have authenticated via gcloud) and add the above roles to that email

I have been using the Google App Engine Launcher's "Deploy" button. I realize that the Launcher is going away at the end of July 2020, so I'm trying to learn to use gcloud. My web site has a custom url, www.xxx.org, but "gcloud app deploy" uploads to xxx.appspot.com instead of to www.xxx.org, presumably because "target url" is set to xxx.appspot.com. Can someone please tell me what gcloud command I need to use to change "target url" to www.xxx.org, or some other scheme that would work? I've wandered through lots of gcloud and GAE documentation and web searches without being able to figure out what I need to do.
There is a very good and complete guide about mapping a custom domain to your application in the official documentation. As #DanCornilescu said,it needs to be configured, but it is not necessary to be done before deployment.
Basically, you need to follow the steps from the guide:
1) Verify that you are the owner of your domain through Webmaster
Central
2)Ensure that your domain has been verified, otherwise you will not be able to proceed with the following steps. Note that only verified domains will be displayed.
3)If you need to delegate the ownership of your domain to other users or service accounts, you can add permission through the Webmaster Central page
4)After you verify ownership of your domain, you can map that domain to your App Engine app
5)Add the resource records that you receive to the DNS configuration of your domain registrar
6)Test for success by browsing to your app via its new domain URL, for example www.example.com
In case you need to do more complex mappings for different urls and subdomains you can always write down the routing rules in the dispatch.yaml file and they will be mapped successfully.
Also, to add a bit more of information about the dipatch.yaml file, it will handle the routing in the App as opposed with the app.yaml which will take care of the App's settings. Both .yamls can exist in the same application and can be deployed at the same time by using the following gcloud command:
gcloud app deploy app.yaml dispatch.yaml
The deployment is always done to .appspot.com, the custom domain is automatically updated if it is already configured. If it is not then it needs to be configured (it can be done after the deployment as well).
I am trying to use Jenkins for CI/CD.
I've developed a Python flask application. I am deploying this application into Google App Engine. So far I am using gcloud app deploy app.yaml command to deploy application to Google App Engine.
Code for this application is present in Google Cloud Source Repository.
Since the authentication to git(Google Cloud Source Repository) requires Google OAuth, I've installed Google OAuth Credentials Plugin
Now I am facing two issues
When I use "Google Service Account from metadata" Credential Kind, I am not seeing the credentials listed in "Source Code Management".
when I use "Google Service Account from private key", I am able to see credentials. But when I run my jenkins job I am getting below error
FATAL: Could not call

Question: How can I authenticate Google Cloud Source repository in Jenkins? What are the steps|plugins required to use Google Cloud Source repository in Jenkins?
Solution
You probably need to add a missing scope to the Compute Engine VM Instance running Jenkins that would give it access to Cloud Source Repository. You can follow the documentation or this steps, which ever you find convenient.
Go to Cloud Deployment Manager
Click on the name of the Jenkins deployment in question
Click on the instance name in the left info pane and it will redirect you to VM instance details
Stop the instance
Press Edit and set the right access scope for Cloud Source Repository
After your start the VM instance, try adding your git repository again and once you select the credentials, either "Google Service Account from metadata" or from service account, everything should work properly.
Elaboration
I stumbled upon the "Invalid authentication credentials." issue while trying to add a Cloud Source Repository after deploying Jenkins from Launcher.
In my case the reason why it happened was that during the process of deployment the Cloud API access scope for Cloud Source Repositories on the Compute Engine VM instance was set to Disabled, which prevented any interaction from that instance even if a service account had all the necessary roles/permissions.
Here are the scopes that are reconfigured by Launcher:
scopes:
- 'https://www.googleapis.com/auth/cloud.useraccounts.readonly'
- 'https://www.googleapis.com/auth/devstorage.read_only'
- 'https://www.googleapis.com/auth/logging.write'
- 'https://www.googleapis.com/auth/monitoring.write'
{% if enableComputeApi %}
- 'https://www.googleapis.com/auth/compute'
{% endif %}
- 'https://www.googleapis.com/auth/cloudruntimeconfig'
Adding the following scope to the VM instance running Jenkins was enough to fix the error:
https://www.googleapis.com/auth/source.read_only
Extra:
List of scopes for Google APIs.
I updated the plugin to 0.6 version.
In 0.6 version, I have the same problem in Jenkins "Free-style" project.
Bit I can success to checkout in Jenkins "pipeline" project.
I just copy the "checkout syntax" in others project and replace 2 parts of the syntax to the right:
credentialsid -> replace to your right credentials id that you created Google Service Account from private key in jenkins.
url ->replace to your google source repository url
I have mistakenly deleted the default "app engine service account" for my project - {id}#appspot.gserviceaccount.com
Is there a way to recover it without resetting/recreating my project on Google Cloud Platform?
Unfortunately at this time, there is no way to recover the default App Engine service account. The solution is as you say creating a new project and redeploying your code there.
Should you wish to see this deletion prevented or default service account recreation made possible in the future, I strongly urge you to file a feature request on the App Engine public issue tracker while providing this example as a business case.
UPDATE: As filed by the OP, a feature request now exists on the App Engine public issue tracker as Issue 13085. Please star this issue to receive updates on its progress.
UPDATE 2: As part of the App Engine Admin API, one can now use the apps.repair API to attempt to address issues of default Cloud Storage buckets and App Engine service accounts. I would recommend trying this API before creating a new project and redeploying. I'm leaving this as an addendum and not the primary solution as it's not guaranteed to solve the issue.
UPDATE 3 It is now possible to undelete service accounts. As per the Undeleting a service account documentation, a service account may be restored if:
The service account was deleted less than 30 days ago
and
There is no existing service account with the same name as the deleted service account.
You can now recover the deleted service accounts from https://cloud.google.com/iam/reference/rest/v1/projects.serviceAccounts/undelete
you have to get the UniqueID of the service account from https://console.cloud.google.com/home/activity
Recover
You can undelete service accounts. You will need the service account's unique ID. If you don't have it, you can find it on Google Cloud Logging.
You can find Logging service here on the side menu:
Then you will need to filter by date and type service account to find the exact moment the service was deleted.
Then you can either
Option 1: Use Google Cloud Command Line
You can run the command line by installing it on your computer (https://cloud.google.com/sdk/docs/install). Or you can run it online using the Active Shell offered by Google Cloud Platform.
The command you want to run is the following.
gcloud beta iam service-accounts undelete 12345678901234567890
Option 2: Use Google Cloud API
Using curl, call the API with the following command.
You will need to change API_KEY, PROJECT_ID and SERVICE_ACCOUNT_UID for real values.
curl -X POST \
-H "Authorization: Bearer API_KEY \
-H "Content-Type: application/json; charset=utf-8" \
-d "" \
"https://iam.googleapis.com/v1/projects/PROJECT_ID/serviceAccounts/SERVICE_ACCOUNT_UID:undelete"
You can get the API_KEY from Google Cloud Command Line:
gcloud auth application-default print-access-token
Again you can either have gcloud installed on your local machine or you can use it online with the Active Shell.
If you don't know the default service account UniqueID, there is another solution.
Simply disable the App Engine Admin API and enable the same after some time. This will create a new default service account. Please note that this will delete all the associated resources.
(To enable/disable an API: Menu -> API & Services -> Dashboard -> Enable APIs and Services -> Search for that API -> Enable/Disable)
Your Account is deleted less than 30 days you can recover it via cloud console
Go to Cloud Console Open Terminal :
Write :
gcloud beta iam service-accounts undelete 100214681451516381413
100214681451516381413 this is the Deleted Account UID .
If You Don't know the Deleted Account ID then GO IAM and Search With Your Deleted Email Address you will find-out the UID there .
Thanks .
I searched the web for a while, but can't seem to find the right answer.
I have created a VM Instance on Google Compute Engine and I am running Jenkins on it. This instance checks a code repository I have and when a change occurs, I want to run the following command
gcloud --project=test preview app deploy -q app.yaml --version=dev
When I want to trigger a build, or it triggers it by himself, I get the following error:
Beginning deployment...
ERROR: Error Response: [403] Request had insufficient authentication scopes.
ERROR: (gcloud.preview.app.deploy) Could not retrieve the default Google Cloud Storage bucket for [test].
Please try again or use the [bucket] argument.
The VM instance does have acces to the storage as you can see in the following image, so I don't understand why this error pops up.
Go to the App Engine developer console https://appengine.google.com/ and in
Application Settings > Cloud integration > and turn ON the Google Cloud Storage
so this will set up the default bucket for you. This something that the new Google Developer Console will do automatically.If the project is created on the old console you have to do it manually.
I followed the steps detailed here to use a custom domain with google app engine.
I'm the admin of the Google Apps account
I'm the owner of the Google App Engine account
I've added the domain to my Google Apps account through my App Engine account
I see my App Engine app in my Google Apps account
I set the CNAME "test" to point to ghs.googlehosted.com
I added the web address under my Google Apps account and it says "Your users can access my-app-id at: test.mydomain.com
Now when I go to http://test.mydomain.com, it redirects to https://test.mydomain.com and I get an SSL connection error (Unable to make a secure connection to the server.)
I called Google Apps customer support because I have a paid business account, but the customer service guy said that this falls under App Engine support and he was not trained in this issue.
Help!
If you've done everything correctly, you should be able to access your site at http://test.mydomain.com. It sounds from the error you're getting that you're attempting to access it at https://test.mydomain.com (https as opposed to http).
If you want to access your app over SSL at your custom domain, you have more setup to do, as documented here: SSL for a Custom Domain. The steps necessary are many and subject to change; that link is the official source of current information on the matter.
Update: From your updated information, it sounds like you may have secure: always set in your app.yaml, or the Java-configuration equivalent of this setting. It would be helpful if you posted your configuration file.
Also note that it takes several minutes for Google to add a certificate on a domain you recently imported (it may require time for DNS configuration to spread). I personally didn't need to add any secure: configuration, it just worked after some time.
