Learn how to deploy a sample app on Cloud Run connected to a SQL Server instance by using the Google Cloud console and a client application.

Assuming that you complete all the steps in a timely manner, the resources created in this quickstart typically cost less than one dollar (USD).

Before you begin

Note: The name you use for your project must be between 4 and 30 characters. When you type the name, the form suggests a project ID, which you can edit. The project ID must be between 6 and 30 characters, with a lowercase letter as the first character. You can use a dash, lowercase letter, or digit for the remaining characters, but the last character cannot be a dash.

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

Public IP

Cloud Run does not support connecting to Cloud SQL for SQL Server over public IP. Use private IP instead.

Private IP

For private IP paths, your application connects directly to your instance through Serverless VPC Access. This method uses a TCP socket to connect directly to the Cloud SQL instance without using the Cloud SQL Auth Proxy.

Go

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.

Public IP

Cloud Run does not support connecting to Cloud SQL for SQL Server over public IP. Use private IP instead.

Private IP

Console

1. In the Google Cloud console, go to the Cloud Run page.

   Go to Cloud Run

2. Click Create container and select Service to display the Create service form.

3. Retain the option to deploy from an existing container image and click Select to specify the gcr.io/YOUR_PROJECT_ID/run-sql container image you created in the previous step.
4. Enter quickstart-service for the Service name.
5. In the Authentication section, select the Allow unauthenticated invocations option. If you don't have permissions (Cloud Run Admin role) to select this, the service will deploy and require authentication.
6. Expand the Container, Variables & Secrets, Connections, Security section.
7. Create the following environment variables by clicking Add variable under Environment variables. Set the values for the environment variables, as follows:
• DB_NAME: Set to quickstart-db.
• DB_USER: Set to sqlserver.
• DB_PASS: Set to the password of the sqlserver user that you created in Create a Cloud SQL instance.
• INSTANCE_CONNECTION_NAME: Set to your instance's Connection name that appears on the Cloud SQL instances page in the Google Cloud console.
• DB_PORT: Set to 1433.
Note: For Java users, the connector already provides a secure connection so the INSTANCE_HOST, DB_ROOT_CERT and PRIVATE_IP environment variables shouldn't be set.
• INSTANCE_HOST: Set to the private IP address of your instance as mentioned in the Cloud SQL instance Overview page.
• DB_ROOT_CERT: Set to certs/server-ca.pem.
• PRIVATE_IP: Set to TRUE.

8. Enable connecting to Cloud SQL:

   1. Click Connections.
   2. Click Add Connection in the Cloud SQL connections section.
   3. Select the quickstart-instance Cloud SQL instance that you previously created.
   4. Select default: Serverless VPC Access Connector "quickstart-connector" from the VPC Network drop-down menu.
   5. Select the option Route all traffic through the VPC connector.

9. Click Create to finish creating the Cloud Run service.

10. After the Cloud Run service is deployed, the Service details page displays the URL of the running service at the top of the page. Click the URL link to see the deployed sample app on Cloud Run connected to Cloud SQL.

    

gcloud

1. Before running the following command, make the following replacements:

• YOUR_PROJECT_ID with your project ID.

• INSTANCE_CONNECTION_NAME with your instance's Connection name that appears on the Cloud SQL instances page in the Google Cloud console.

• DB_PASS with the password of the sqlserver user that you created in Create a Cloud SQL instance.
• INSTANCE_HOST with the private IP address of your instance. Go to the Cloud SQL instance Overview page where the instance private IP address appears.

Run the gcloud run deploy command as follows to create the Cloud Run service:

gcloud run deploy run-sql --image gcr.io/YOUR_PROJECT_ID/run-sql \
  --add-cloudsql-instances INSTANCE_CONNECTION_NAME \
  --vpc-connector="quickstart-connector" --vpc-egress=all-traffic \
  --set-env-vars DB_NAME="quickstart-db" \
  --set-env-vars DB_USER="sqlserver" \
  --set-env-vars DB_PASS="DB_PASS" \
  --set-env-vars INSTANCE_CONNECTION_NAME="INSTANCE_CONNECTION_NAME" \
  --set-env-vars DB_PORT="1433" \
  --set-env-vars INSTANCE_HOST="INSTANCE_HOST" \
  --set-env-vars DB_ROOT_CERT="certs/server-ca.pem" \
  --set-env-vars PRIVATE_IP="TRUE"

Java users should run the gcloud run deploy command without the INSTANCE_HOST, DB_ROOT_CERT, and PRIVATE_IP --set-env-vars flags, as follows, to create the Cloud Run service because the Java connector already provides a secure connection:

gcloud run deploy run-sql --image gcr.io/YOUR_PROJECT_ID/run-sql \
  --add-cloudsql-instances INSTANCE_CONNECTION_NAME \
  --vpc-connector="quickstart-connector" --vpc-egress=all-traffic \
  --set-env-vars DB_NAME="quickstart-db" \
  --set-env-vars DB_USER="sqlserver" \
  --set-env-vars DB_PASS="DB_PASS" \
  --set-env-vars INSTANCE_CONNECTION_NAME="INSTANCE_CONNECTION_NAME" \
  --set-env-vars DB_PORT="1433"

Enter the numeric choice provided for us-central1 when prompted to specify a region.

2. When you see a confirmation message that the Cloud Run service has been deployed, click the Service URL link in the message to see the sample app on Cloud Run that is connected to Cloud SQL.
