Enable the Cloud APIs necessary to run a Cloud SQL sample app on Cloud Run.
Console
Click Enable APIs to enable the APIs required for this quickstart.
This enables the following APIs:
- Compute Engine API
- Cloud SQL Admin API
- Cloud Run API
- Container Registry API
- Cloud Build API
- Service Networking API
gcloud
Click the following button to open Cloud Shell, which provides command-line access to your Google Cloud resources directly from the browser. Cloud Shell can be used to run the
gcloud
commands presented throughout this quickstart.Run the following
gcloud
command using Cloud Shell:gcloud services enable compute.googleapis.com sqladmin.googleapis.com run.googleapis.com \ containerregistry.googleapis.com cloudbuild.googleapis.com servicenetworking.googleapis.com
This command enables the following APIs:
- Compute Engine API
- Cloud SQL Admin API
- Cloud Run API
- Container Registry API
- Cloud Build API
- Service Networking API
Set up Cloud SQL
Create a Cloud SQL instance
Create a database
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- Select
quickstart-instance
. - From the SQL navigation menu, select Databases.
- Click Create database.
- In the Database name field of the New database dialog
box, enter
quickstart-db
. - Click Create.
gcloud
Run the gcloud
sql databases create
command to create a database.
gcloud sql databases create quickstart-db --instance=quickstart-instance
Create a user
Console
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- To open the Overview page of an instance, click the instance name.
- Select Users from the SQL navigation menu.
- Click Add user account.
- On the Add a user account to instance instance_name page,
add the following information:
- In the Username field, enter
quickstart-user
- In the Password field, specify a password for your database user. Make a note of this for use in a later step of this quickstart.
- In the Username field, enter
- Click Add.
gcloud
Before running the following command, make the following replacements:
- PASSWORD with a password for your database user. Make a note of this for use in a later step of this quickstart.
Run the gcloud sql users create
command to create the user.
gcloud sql users create quickstart-user \ --instance=quickstart-instance \ --password=PASSWORD
User name length limits are the same for Cloud SQL as for on-premises PostgreSQL.
Deploy sample app to Cloud Run
Configure a Cloud Run service account
Console
-
In the Google Cloud console, go to the IAM page.
- For the service account named Compute Engine default service account, click the pencil icon.
- Click ADD ANOTHER ROLE.
- Add the Role named Cloud SQL Client.
- Click Save.
gcloud
-
Run the following
gcloud
command to get a list of your project's service accounts:gcloud iam service-accounts list
- Copy the EMAIL of the Compute Engine service account.
- Run the following command to add the Cloud SQL Client
role to Compute Engine service account:
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \ --member="serviceAccount:SERVICE_ACCOUNT_EMAIL" \ --role="roles/cloudsql.client"
Configure a Cloud SQL sample app
With a Cloud SQL instance, database, and service account with client permissions, you can now configure a sample application to connect to your Cloud SQL instance.
Deploy the sample app
The steps to deploy the sample to Cloud Run depend on the type of IP address you assigned to your Cloud SQL instance.
Clean up
To avoid incurring charges to your Google Cloud account for the resources used on this page, follow these steps.
-
In the Google Cloud console, go to the Cloud SQL Instances page.
- Select the
quickstart-instance
instance to open the Instance details page. - In the icon bar at the top of the page, click Delete.
- In the Delete instance dialog box, type
quickstart-instance
, and then click Delete to delete the instance. -
In the Google Cloud console, go to the Cloud Run page.
- Select the checkbox next to the
quickstart-service
service name. - Click Delete at the top of the Cloud Run page.
Optional cleanup steps
If you're not using the Cloud SQL client role that you assigned to the Compute Engine service account, you can remove it.
-
In the Google Cloud console, go to the IAM page.
- Click the edit icon (which looks like a pencil) for the IAM account named Compute Engine default service account.
- Delete the Cloud SQL client role.
- Click Save.
