1. Login to the GCP console: https://console.cloud.google.com/
2. Navigate to the Cloud Functions page by clicking on the hamburger menu on the top left corner and selecting “Cloud Functions” under the “Compute” section.
3. Select the function that is using the same IAM role as another function.
4. Click on the “Edit” button on the top of the Cloud Function page.
5. Scroll down to the “Cloud Function Details” section and click on the “Show Advanced Settings” button.
6. Under the “Cloud Function IAM” section, click on the “Change” button next to the “Service account” field.
7. In the “Select a service account” dialog box, select “Create a new service account” and give it a name.
8. Click on the “Create” button and wait for the service account to be created.
9. Select the newly created service account from the drop-down list and click on the “Save” button at the bottom of the page.
10. Repeat the above steps for all the other functions that are using the same IAM role.

​

1. Open the Google Cloud Console and navigate to the Cloud Functions page.
2. Identify the Cloud Functions that are using the same IAM role.
3. Create a new IAM role for each Cloud Function that is currently sharing a role.
4. Assign the newly created IAM role to the respective Cloud Function.
5. Remove the old IAM role from the Cloud Function.

1. Open the GCP CLI and run the command below to list all the Cloud Functions:

gcloud functions list

2. Identify the Cloud Functions that are using the same IAM role.
3. Create a new IAM role for each Cloud Function that is currently sharing a role using the command below:

gcloud iam roles create [ROLE_NAME] --project [PROJECT_ID] --file [ROLE_DEFINITION_FILE_PATH]

4. Assign the newly created IAM role to the respective Cloud Function using the command below:

gcloud functions add-iam-policy-binding [FUNCTION_NAME] --member [MEMBER] --role [ROLE_NAME]

5. Remove the old IAM role from the Cloud Function using the command below:

gcloud functions remove-iam-policy-binding [FUNCTION_NAME] --member [MEMBER] --role [OLD_ROLE_NAME]

1. Create a new IAM role for each cloud function that needs to be deployed.
2. Assign the appropriate permissions to the IAM role based on the requirements of the cloud function.
3. Update the cloud function deployment script to include the newly created IAM role for each function.
4. Update the cloud function configuration to use the newly created IAM role for each function.

from google.cloud import iam

# Create a new IAM client
client = iam.IAMClient()

# Define the IAM role name and description
role_name = 'my-function-role'
role_title = 'My Cloud Function Role'
role_description = 'This role is used by my cloud function.'

# Define the IAM role permissions
permissions = [{'service': 'cloudfunctions.googleapis.com', 'method': 'cloudfunctions.functions.create'}, {'service': 'cloudfunctions.googleapis.com', 'method': 'cloudfunctions.functions.delete'}, {'service': 'cloudfunctions.googleapis.com', 'method': 'cloudfunctions.functions.get'}, {'service': 'cloudfunctions.googleapis.com', 'method': 'cloudfunctions.functions.list'}, {'service': 'cloudfunctions.googleapis.com', 'method': 'cloudfunctions.functions.update'}]

# Create the new IAM role
new_role = client.create_role(role_name, title=role_title, description=role_description, included_permissions=permissions)

# Print the newly created IAM role
print(new_role)
