We suggest that you try out one of the sample apps that we've reconfigured for Managed VMs. Download the sample source code from github, check out what's changed in the configuration file, and deploy the app to a VM.

Download the sample code and the App Engine SDK

The quickstart samples are available in Python, Go, and Java. Follow the link to download the code from GitHub. Click the App Engine SDK link and follow the instructions to download and install the SDK for your particular local development machine.

import GOPATH=$HOME/go
<sdk_path>/goapp get google.golang.org/appengine

View the config file

The sample config file will start one instance of an n1-standard machine type. The lines that have been added/edited for managed VMs are in boldface.

application: your-application-id
runtime: python27
vm: true

manual_scaling:
  instances: 1
vm_settings:
  machine_type: n1-standard-1

  </vm-settings>

</appengine-web-app>

Deploy your app

Use the update command.

  <python_sdk_path>/appcfg.py -s preview.appengine.google.com update <app-directory>
  

  <go_sdk_path>/appcfg.py -s preview.appengine.google.com update <app-directory>
  

If you have two-step verification enabled on your Google account, add the --oauth2 flag, otherwise, you will need to provide an application password.

  <java_sdk_path>/appcfg.sh -s preview.appengine.google.com update <EAR-or-WAR-directory>
