Deploy a new service to app engine project

Here are the steps to deploy a new service to an App Engine project:

Prerequisites:

  1. You have a Google Cloud account and a project created.
  2. You have the gcloud command-line tool installed and configured.
  3. You have a directory containing your application code.

Step 1: Create a new service

In your terminal, navigate to the directory containing your application code and run the following command:

gcloud app services create <service-name> --platform standard --region <region>

Replace <service-name> with a unique name for your service (e.g., "my-service") and <region> with the region where you want to deploy your service (e.g., "us-central1").

Step 2: Configure your app.yaml file

Create a new file named app.yaml in the root of your project directory. This file contains configuration settings for your App Engine service.

Here's an example app.yaml file:

runtime: python
env: flex

handlers:
- url: /.*
  script: auto

env_variables:
  FLEXIBLE_ENV_VAR: "hello"

This example app.yaml file specifies a Python runtime, a flexible environment, and sets an environment variable FLEXIBLE_ENV_VAR to "hello".

Step 3: Deploy your service

Run the following command to deploy your service:

gcloud app deploy app.yaml --promote

This command deploys your service to the App Engine platform and promotes it to the production environment.

Step 4: Verify your service

Once the deployment is complete, you can verify that your service is running by visiting the URL https://<service-name>.<region>.r.appspot.com in your web browser. Replace <service-name> with the name of your service and <region> with the region where you deployed your service.

That's it! You have successfully deployed a new service to your App Engine project.
