For apps created after\nFebruary 2020, \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e`.r` is included in\nApp Engine URLs. For existing apps created before this date, the\nregion ID is optional in the URL.\n\nLearn more\n[about region IDs](/appengine/docs/flexible/python/how-requests-are-routed#region-id). \nOK\n\nThis section describes how to use ingress settings to restrict network access to\nyour App Engine app. At a network level, by default, any resource on\nthe internet is able to reach your App Engine app on its\n[appspot URL](/appengine/docs/flexible/how-requests-are-routed)\nor at a [custom domain](/appengine/docs/flexible/mapping-custom-domains)\nset up in App Engine. For example, the `appspot.com` URL can have the\nfollowing format:\n\u003cvar translate=\"no\"\u003eSERVICE_ID\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.`\u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e`.r.appspot.com`.\n\nYou can change this default setting by specifying a\ndifferent setting for ingress. All ingress paths, including the default\n`appspot.com` URL, are subject to your ingress setting. Ingress is set at the\nservice level.\n\nAvailable ingress settings\n--------------------------\n\nThe following settings are available:\n\n### Accessing internal services\n\nThe following considerations apply:\n\n- For requests from a Shared VPC, traffic is only considered internal if the\n App Engine app is deployed in the Shared VPC host project. If the\n App Engine app is deployed in a Shared VPC service project, only traffic\n from networks owned by the app's own project is internal. All other traffic,\n including traffic from other Shared VPCs, is external.\n\n- When accessing internal services, call them as you would normally do by using\n their public URLs, either the default `appspot.com` URL or a\n [custom domain](/run/docs/mapping-custom-domains) set up in App Engine.\n\n- For requests from Compute Engine VM instances or other resources running\n inside a\n\n [VPC network](/appengine/docs/flexible/using-shared-vpc)\n in the same project, no further setup is required.\n\n- Requests from resources within VPC networks in the same project are classified\n as internal even if the resource they originate from has a public IP address.\n\n- Requests from on-premises resources connected to the VPC network via\n Cloud VPN are considered `internal`.\n\n### View ingress settings\n\n### Console\n\n1. Go to the App Engine Services page.\n\n [Go to the Services page](https://console.cloud.google.com/appengine/services)\n2. Locate the **Ingress** column. For each service, the value in this column\n shows the ingress setting as one of **All** (default),\n **Internal + Load Balancing** , or **Internal**.\n\n### gcloud\n\nTo view the ingress setting for a service using the gcloud CLI: \n\n```bash\ngcloud app services describe SERVICE\n```\n\nReplace \u003cvar translate=\"no\"\u003eSERVICE\u003c/var\u003e with the name of your service.\n\nFor example, to view the ingress settings and other information for the\ndefault service run: \n\n```bash\ngcloud app services describe default\n```\n\n\u003cbr /\u003e\n\n### Edit ingress settings\n\n### Console\n\n1. Go to the App Engine Services page.\n\n [Go to the Services page](https://console.cloud.google.com/appengine/services)\n2. Select the service you wish to edit.\n\n3. Click **Edit ingress setting**.\n\n4. Select the ingress setting that you want from the menu and click\n **Save**.\n\n### gcloud\n\nTo update the ingress setting for a service using the gcloud CLI: \n\n```bash\ngcloud app services update SERVICE --ingress=INGRESS\n```\n\nReplace:\n\n- \u003cvar translate=\"no\"\u003eSERVICE\u003c/var\u003e: The name of your service.\n- \u003cvar translate=\"no\"\u003eINGRESS\u003c/var\u003e: The ingress control you want to apply. One of `all`, `internal-only`, or `internal-and-cloud-load-balancing`.\n\nFor example:\n\n- To update the default service of an App Engine app to accept traffic\n only from Cloud Load Balancing and VPC networks that are in the same\n project:\n\n ```bash\n gcloud app services update default --ingress=internal-and-cloud-load-balancing\n ```\n- To update a service named \"internal-requests\" to accept traffic only from VPC\n networks that are in the same project:\n\n ```bash\n gcloud app services update internal-requests --ingress=internal-only\n ```\n\n\u003cbr /\u003e"]]
