In addition to administrative actions such as creating, updating, and deleting services, developers often want to test services privately before releasing them.
Before you start
Make sure you grant permissions to access the services you are authenticating to. You must grant the Cloud Run Invoker role to the developer or group of developers:
Go to the Google Cloud Console:
Select the service.
Click Show Info Panel in the top right corner to show the Permissions tab.
Click Add members.
In the Add members field, enter the developer account email.
Cloud Run Invokerrole from the Select a role drop-down menu.
gcloud run services add-iam-policy-binding command:
gcloud run services add-iam-policy-binding SERVICE \ --member='USER:EMAIL' \ --role='roles/run.invoker'
- SERVICE is the name of the service.
- USER is the value
groupdepending on whether you are authorizing a single developer or a group.
EMAIL is the email account.
gcloud run services add-iam-policy-binding myservice \ --member='user:firstname.lastname@example.org' \ --role='roles/run.invoker'
Testing your private service
The easiest way to test a service that requires authentication is to use a tool
curl and pass an auth token in the
curl -H "Authorization: Bearer $(gcloud auth print-identity-token)" SERVICE_URL
In order for the
curl command to work, you must pass a valid identity token
for a user with the
run.routes.invoke permission, such as the
Cloud Run Admin or Cloud Run Invoker. See
Cloud Run IAM Roles for the full
list of roles and their assoiciated permissions.
As shown in the example, in order to get a valid identity token for the identity
currently logged into
gcloud, you can use
gcloud auth print-identity-token.
For convenient reuse, you can create a command-line alias in your Linux or macOS shell profile:
alias gcurl='curl --header "Authorization: Bearer $(gcloud auth print-identity-token)"'
Use it to make requests to your services:
gcurl OPTIONAL_CURL_FLAGS SERVICE_URL
To test a website or API in your browser, you can use browser extensions that modify HTTP request headers.
