I have a spring boot rest project which is running successfully, and I am getting success response on http://localhost:8080/students. How can I expose this SpringBoot REST API into a private AWS API GATEWAY? I have to expose the REST API service, and I have to give the endpoints to the client, to access this service. I have no idea how to present and create endpoints in AWS API GATEWAY!
API Gateway will work as mediator between clients and your application. So in the first place your application should be exposed so AWS Gateway could make a call to it.
If you are running application on your local pc you need to expose it to Internet by setting static IP and openning corresponding ports in firewall if you have one. This may works for debug/testing purpose, but in general it is bad because you will expose your application to Internet and client services would have possibility to connect to it directly, instead of gateway.
Other and more proper on my opinion would be to run your application in AWS EC2 instance or in AWS beanstalk. In this case you can configure private endpoint for your application and make it available only through API Gateway. Here you can find more details https://aws.amazon.com/blogs/compute/introducing-amazon-api-gateway-private-endpoints/
So let's suppose you have your application up and running and available for API Gateway. In this case you will need to perform :
Create API in API Gateway
Create resources, i.e. path /user would be user resource
For each resource create a method, i.e. GET, POST, etc. Select integration type HTTP for your methods and set the endpoint it will use
Deploy API to staging

I have a kotlin REST microservice exposing several endpoints on beanstalks, and an AWS API Gateway.
I want to know if there is a lib or service doing the following :
Discover the enpoints deployed on one (or several) microservice(s)
Generate and deploy API Gateway documentation, preferably with some config to tell what endpoint we want to hide / display on the gateway
I am trying to run a cloud run/ cloud functions service through google API gateway. I am using firebase authentication on the gateway as security.
Initially, I had my services private and was getting 403. It gave me 200 once I added allUsers with Cloud Run Invoker to the permissions to the service I am trying to invoke. So I am a bit confused here. Part of the reason I am using API gateway with firebase auth is to protect it against unauthorised calls. And for firebase auth to work, I had to add allUsers, making it public. My understanding was that the API gateway alone would be public while all the backend services that it invokes would be private. In this case, the service can be directly invoked by anyone, rendering the security at the API Gateway useless. How can I setup the backend to private and only respond to authenticated calls through API gateway ?
I'm new to the GCP Services, and I'm trying to make an API Gateway to proxy two services, one is run on an App Engine and the other is actually a PaaS.
Can I configure Cloud Endpoints to redirect to that PaaS, and how? and if now what service in GCP suits this case?
Edit:
An example of what I'm trying to do is if my domain is test.com then i'd like app.test.com to be redirected to my App Engine and ip.test.com would be directed for example to https://httpbin.org/ip.
I wrote an article on this for securing the endpoint. Set the value that you want in the x-google-backend.
I also provide some tips about the URL rewriting if you want.
EDIT 1
If you want to perform this routing
app.test.com -> App Engine
ip.test.com -> External service
You need to use a HTTPS Load Balancer and not API Gateway.
Then,
create a serverless NEG and configure it with App Engine
create an Internet NEG and configure it to reach your internet accessible PaaS service
Create a URL MAP with the correct routing
That's all (wait 3 - 5 minutes, the delay to dispatch your configuration around the globe.)
Yes, you can run an Extensible Service Proxy in front of your non-GCP backend service so that Cloud Endpoints can proxy requests to it.

How to integrate API gateway with application load balancer? I have integrated ECS with ALB, now I want to add API gateway in front without lambda. But I got confused how to connect API gateway with ALB..
What you're probably looking for is the HTTP Proxy Integration as described here
The basic idea is this:
Set up your API-Gateway with a greedy path like /{proxy+} on the ANY Method
Set the backend-endpoint to https://my-alb-endpoint.com/ecs-service-bla/{proxy}
(hopefully) success
To make this work, your backend needs to be exposed to the internet (or at least reachable for the API Gateway)!
You probably should keep your backend within a locked down VPC, but for this you're going to need to set up a private integration, which requires a Network Load balancer - this might be costlier, but would be the recommended approach.
Yes you can do . Inside API Gateway under integration type select HTTP and then provide complete path of ALB with endpoint resource.
I have a confusing scenario. I am new to AWS. I have some available services written in java jersy and I have them deployed on an Ec2 instance.
I am asked to use API gateway to call these services rather than calling them directly. So for instance if I have a service as follows:
http://domainname/article/2
I want the front end to first call the following endpoint of API gateway:
https://my-api-id.execute-api.region-id.amazonaws.com/stage-name/article
and then the above API Gateway end point call the my service.
What I am thinking is there is a http proxy in integration type when I try to create the API gateway resource. I assume this can fit my purpose but I am not sure about it and I am totally confused.
Can anyone shed light on how I can achieve that?
In the API Gateway Console, create a resource (eg. /v1/user/info) and method (eg. GET/POST etc).
Select Integration Request
You can then configure a an HTTP Proxy or a Lambda function any other AWS Resource. In your case, you want this to be pointing to your EC2 hosted URL.
