This page describes how to configure DNS for Cloud Endpoints APIs
.endpoints.PROJECT_ID.cloud.goog as the Endpoints service
name. The configuration steps on this page are applicable for APIs using
OpenAPI running on Compute Engine, Google Kubernetes Engine, or Kubernetes.
After your API is deployed, you will want the users of your API to be able to access it through a domain name rather than an IP address. You can either:
- Configure the
.endpoints.PROJECT_ID.cloud.googas the domain name, as described on this page.
- Or register your own domain name (for example,
my-company.com), which entails:
.cloud.goog domain is managed by Google and shared by Google
Cloud Platform (GCP) customers. Because GCP Console projects are
guaranteed to have a globally unique project ID, a domain name in the format
.endpoints.PROJECT_ID.cloud.goog is unique and can be used as the
domain name in the URL for your API.
Note the following:
- Configuring the
.endpoints.PROJECT_ID.cloud.googdomain name is optional. If you prefer, you can register your own domain name.
.endpoints.PROJECT_ID.cloud.googdomain name is not supported for APIs running on App Engine. For APIs on App Engine, we recommend that you use
YOUR_PROJECT_ID.appspot.comas the Endpoints service name. When you deploy the API to App Engine, a DNS entry with a name in the format
YOUR_PROJECT_ID.appspot.comis created automatically.
As a starting point, this page assumes that you have already created your Endpoints API and deployed it to Compute Engine, Google Kubernetes Engine, or Kubernetes. If you need an API for testing, you can use one of the tutorials that walk you through configuring and deploying a sample API.
The following procedure describes how to configure DNS for Cloud Endpoints
APIs that use
.endpoints.PROJECT_ID.cloud.goog as the Endpoints service name.
For convenience, the procedure refers to your OpenAPI configuration file
To configure DNS:
openapi.yaml, and add the
x-google-endpointsfield to the file as shown in the following snippet:
swagger: "2.0" host: "[API_NAME].endpoints.[PROJECT_ID].cloud.goog" x-google-endpoints: - name: "[API_NAME].endpoints.[PROJECT_ID].cloud.goog" target: "[IP_ADDRESS]"
Typically, you configure the
hostfield and the
x-google-endpoints.namefield to be the same. When you deploy your OpenAPI specification, the text specified in the
hostfield is used as the name of your Endpoints service.
[API_NAME]with the name of your API (for example,
[PROJECT_ID]with your Cloud project ID.
[IP_ADDRESS]with an IPv4 address.
For example, if you deploy your Endpoints API service to a Compute Engine virtual machine instance, you can use the external IP of that virtual machine. Alternatively, if you run your code on a group of virtual machine instances (or Kubernetes Engine pods) behind a load balancer, you can use the IP address of the load balancer.
- Deploy your new OpenAPI specification to Service Management using the following command:
gcloud endpoints services deploy openapi.yaml
For example, if the following is specified in an
swagger: "2.0" host: "my-cool-api.endpoints.my-project-id.cloud.goog" x-google-endpoints: - name: "my-cool-api.endpoints.my-project-id.cloud.goog" target: "192.0.2.1"
When you deploy the
openapi.yaml using the above
gcloud command, Service
Management creates a DNS A-record,
id.cloud.goog, which resolves to the target IP address, 192.0.2.1. You might
need to wait a few minutes for the new DNS configuration to propagate.
