To learn more about\nthe Java runtime environment, see\n[Java Runtime Environment](/appengine/docs/standard/java-gen2/runtime).\n\nBefore you begin\n----------------\n\n1. [Create a Google Cloud project with an App Engine app](/appengine/docs/standard/java-gen2/building-app/creating-project).\n2. [Write a Java web server ready to deploy on App Engine](/appengine/docs/standard/java-gen2/building-app/writing-web-service).\n3. [Install Google Cloud CLI](/sdk/docs/install), which provides the `gcloud` command-line tool. Ensure `gcloud` is configured to use the Google Cloud project you want to deploy to.\n\nKey points\n----------\n\n- Use `gcloud app deploy` and `gcloud app browse` to deploy and view your service.\n\nDeploy your service\n-------------------\n\nIn your `my-java-service` folder, where your Maven POM or\nGradle build file is located, run the following command in your terminal: \n\n gcloud app deploy\n\nYour source files are then uploaded to Cloud Storage. Cloud Build\nbuilds your app and deploys it to App Engine.\n| **Note:** Files listed in your [`.gcloudignore`](/sdk/gcloud/reference/topic/gcloudignore) file will not be uploaded.\n\n### Deploy multiple services\n\nYou can add multiple services in your project by creating an `app.yaml` file for each service. Include the\n`service` attribute in each `app.yaml` file to specify the name of the service.\nTo learn more about structuring your app using multiple services, see\n[Structuring Web Services in App Engine](/appengine/docs/standard/configuration-files#directory_structure).\n\nTo deploy multiple services, follow [these instructions](/appengine/docs/standard/testing-and-deploying-your-app#deploying_multiple_services)\n\nEach deployed service will have its own assigned URL.\n\nView your service\n-----------------\n\nTo quickly launch your browser and access your web service at\n\n`https://`\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003e\u003ca href=\"#appengine-urls\" style=\"border-bottom: 1px dotted #999\" class=\"devsite-dialog-button\" data-modal-dialog-id=\"regional_url\" track-type=\"progressiveHelp\" track-name=\"modalHelp\" track-metadata-goal=\"regionalURL\"\u003eREGION_ID\u003c/a\u003e\u003c/var\u003e`.r.appspot.com`, use the following\ncommand: \n\n gcloud app browse\n\nServices and versions\n---------------------\n\nYou've just created and deployed a service on App Engine.\nYou can specify the name of your service in the `app.yaml` file. If the\nname is omitted, it is treated as `default`. The first service you deploy\nmust be the default service.\n\nYou can update your service at any time by running the `gcloud app deploy`\ncommand again. Each time you deploy, a new version is created and traffic\nis automatically routed to the latest version.\n\nTo confirm that your service has been created and a version has been deployed:\n\n1. View your App Engine services in the Google Cloud console:\n\n [View services](https://console.cloud.google.com/appengine/services)\n\n You should see one service listed, named `default`. The default service is\n publicly accessible at the following URL:\n\n\n `https://`\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003e\u003ca href=\"#appengine-urls\" style=\"border-bottom: 1px dotted #999\" class=\"devsite-dialog-button\" data-modal-dialog-id=\"regional_url\" track-type=\"progressiveHelp\" track-name=\"modalHelp\" track-metadata-goal=\"regionalURL\"\u003eREGION_ID\u003c/a\u003e\u003c/var\u003e`.r.appspot.com`\n2. View your versions:\n\n [View versions](https://console.cloud.google.com/appengine/versions)\n\n You should see one timestamped version listed, corresponding to your\n deployment.\n\nTo learn how to send requests to specific services and versions, see\n[How Requests are Routed](/appengine/docs/standard/how-requests-are-routed).\n\nNext steps\n----------\n\nCongratulations! You built an application that can store and classify uploaded\nimages. Learn how to add other features to your application by exploring the\nfollowing pages:\n\n- See more Java code samples for the App Engine standard environment on the [Google Cloud GitHub repository.](https://github.com/GoogleCloudPlatform/java-docs-samples/). These samples can be used for both Java.\n- Learn more about writing application logs and interpreting system logs in [Reading and writing application logs](/appengine/docs/standard/writing-application-logs).\n- For a deeper dive into how App Engine works, see the [Java runtime environment](/appengine/docs/standard/java-gen2/runtime)."]]
