Deploy a PHP App
App Engine: Qwik Start - PHP
App Engine allows developers to focus on doing what they do best—write code. The App Engine standard environment is based on container instances running on Google's infrastructure. Containers are preconfigured with one of several available runtimes (Java 7, Java 8, Python 2.7, Go and PHP). Each runtime also includes libraries that support App Engine Standard APIs. For many applications, the standard environment runtimes and libraries might be all you need.
The App Engine standard environment makes it easy to build and deploy an application that runs reliably even under heavy load and with large amounts of data. It includes the following features:
- Persistent storage with queries, sorting, and transactions.
- Automatic scaling and load balancing.
- Asynchronous task queues for performing work outside the scope of a request.
- Scheduled tasks for triggering events at specified times or regular intervals.
- Integration with other Google cloud services and APIs.
Applications run in a secure, sandboxed environment, allowing App Engine standard environment to distribute requests across multiple servers, and scaling servers to meet traffic demands. Your application runs within its own secure, reliable environment that is independent of the hardware, operating system, or physical location of the server.
This hands-on lab shows you how to create a small App Engine application that displays a short message.
What you'll do
Download an application
Test the application
Deploy the application
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.
What you need
To complete this lab, you need:
- Access to a standard internet browser (Chrome browser recommended).
- Time to complete the lab.
Note: If you already have your own personal Google Cloud account or project, do not use it for this lab.
Note: If you are using a Chrome OS device, open an Incognito window to run this lab.
How to start your lab and sign in to the Google Cloud Console
Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is a panel populated with the temporary credentials that you must use for this lab.
Copy the username, and then click Open Google Console. The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Open the tabs in separate windows, side-by-side.
In the Sign in page, paste the username that you copied from the left panel. Then copy and paste the password.
Important: You must use the credentials from the left panel. Do not use your Google Cloud Training credentials. If you have your own Google Cloud account, do not use it for this lab (avoids incurring charges).
Click through the subsequent pages:
- Accept the terms and conditions.
- Do not add recovery options or two-factor authentication (because this is a temporary account).
- Do not sign up for free trials.
After a few moments, the Cloud Console opens in this tab.
Activate Cloud Shell
Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.
In the Cloud Console, in the top right toolbar, click the Activate Cloud Shell button.
It takes a few moments to provision and connect to the environment. When you are connected, you are already authenticated, and the project is set to your PROJECT_ID. For example:
gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.
You can list the active account name with this command:
You can list the project ID with this command:
Enable Google App Engine Admin API
The App Engine Admin API enables developers to provision and manage their App Engine Applications.
In the left menu, click APIs & Services > Library.
Type "App Engine Admin API" in search box.
Click App Engine Admin API.
Download the Hello World app
We've created a simple Hello World app for PHP so you can quickly get a feel for deploying an app to Google Cloud. Follow these steps to download Hello World to your Google Cloud instance.
Enter the following command to clone the Hello World sample app repository to your Google Cloud instance:
Go to the directory that contains the sample code:
Deploy your app
To deploy your app to App Engine, run the following command from within the root directory of your application where the
app.yaml file is located:
Enter the region you want your application located.
Enter Y when prompted to confirm the deployment of service.
View your application
To launch your browser enter the following command:
Sample output, your link will be different:
Click on the link to view your application.
Your application is deployed and you can read the short message in your browser.
Click Check my progress to verify the objective.
Make a change
Let's make a change to your sample app. Open the index.php file with the nano editor:
Change "hello world!" to "goodbye world!".
Press CTRL + X > Y > Enter to exit and save the file.
In Cloud Shell, run the following command to redeploy your application:
Enter Y when prompted to confirm the deployment of service.
Soon after you should receive the following output:
Refresh the browser tab with your App Engine deployment. You should see the following:
