apig | Golang RESTful API Server Generator | REST library

I want to deploy a APIGateway with mock integration for testing via serverless using this example.

However when I try to deploy it I get the following error:

new to the CDK and relatively new to AWS

I'm following this tutorial which includes creating a fargate based private API, and accessing it on the public internet through an ec2 instance which is publicly exposed.

I'm picking through, minimally correcting various issues which gets everything running. It comes time to build with:

I have some TypeScript code that uses CDK to create an API Gateway and a Lambda. It works and deploys to a standard AWS URL. So far so good.

I now need to transfer the API Gateway so that it operates on a custom domain, so that it can set a cookie in a web app. This is proving far harder, and I suspect I am having difficulty because I am new to TypeScript, AWS, and CDK all at the same time. There are a number of documentation resources on the web, but most would require me to rewrite the precious little working code I have, which I am reluctant to do.

I have created a certificate manually, because that requires validation and thus it does not make sense to create it in code. Other than that I want all other resources to be created by CDK code in a Stack. In my view, it defeats the purpose of CDK if I have to configure things manually.

The below code deploys everything I need to gatekeeper.d.aws.example.com - a HostedZone, an ARecord, a LambdaRestApi and a Function (lambda). However it does not work because the NS records newly assigned to gatekeeper.d.aws.example.com do not match the ones in the parent d.aws.example.com.

I think this means that although d.aws.example.com is "known", the gateway subdomain cannot delegate to it.

Here is my working code:

On of my API Gateway logs entries indicates a timeout and I'm investigating where it's coming from. The log entry has an X-Ray trace ID but when I use X-Ray to search for it, I get "Data not found".

I'm expecting at least one node, the APIG , to show up in X-Ray. What am I missing?

API Gateway CloudWatch Logs Insights I cannot find trace for

query-string:

I've a Lambda which makes an API request to a service and get a list of matches for a given identifier. Once it gets a list of matches it updates a DynamoDB table in the following way:

For each match in this table, a message is sent to SQS which is listened to by a Lambda. For each match, the Lambda will make a call to a different service and update a table which keeps track of the matches execution.

Now given the requestId, I would like to know if there are entries in the 2nd table for all matches.

One option I'm thinking is look up the first table via the requestId and it will give the list of matches, then it will call the 2nd table multiple times via the primary key, sortKey combination and compile a result. The other option is instead of looking up via primary key/sort key for 2nd table, it will look via a GSI Parition key on the requestId column and get all the matches at once (in a paginated list).

I would like to expose this operation via an API call, and I'm wondering if I'll run into APIG 30 seconds timeout (I know I'll need to run some experiments with my dataset, but just wanted to see if there are other options I can consider before doing this). If number of matches exceed say 50,000. And each get call roughly takes 20ms, it will take about 50,000 * 20 = 1000 seconds which is way more than APIG limit. Maybe batch call might help a bit, but not sure there is much room there.

Essentially I would like to update the status in the first table from FOUND_MATCHES to ALL_MATCHES_PROCESSED.

1. Ideal option is automatically the state gets updated
2. A Get status API essentially triggers the calculation and updates the state (Maybe make this async to get past the 30seconds APIG limitation)

What is the AWS recommendation for hosting multiple micro-services? can we host all of them on same APIG/Lambda? With this approach, I see when want to update an API of one service then we are deploying API of all services which means our regression will include testing access of all services. On the other hand creating separate APIG/Lambda per service we will end up with multiple resources (and multiple accounts) to manage, can be operational burden later on?

Using CDK to connect ApiGateway to a lambda, we first create a RestApi(), and then create a LambdaIntegration to connect the Apigateway to a lambda. How do you do this when working with a lambda Alias?

How to point ApiGateway to a specific Lambda alias explains how to connect ApiG to a Lambda alias without CDK. How can this be translated to CDK?

Our goal is to add provisioned concurrency and autoscaling to a lambda used with API Gateway.

I want to use AWS CDK to define an API Gateway and a lambda that the APIG will proxy to.

The OpenAPI spec supports a x-amazon-apigateway-integration custom extension to the Swagger spec (detailed here), for which an invocation URL of the lambda is required. If the lambda is defined in the same stack as the API, I don't see how to provide this in the OpenAPI spec. The best I can think of would be to define one stack with the lambda in, then get the output from this and run sed to do a find-and-replace in the OpenAPI spec to insert the uri, then create a second stack with this modified OpenAPI spec.

Example:

My stage has xray tracking enabled and I can see X-Amzn-Trace-Id is coming back from API gateway, moreover, I'm able to see the whole trace from APIG to Dynamo db. I would like to save this trace id to the table, so we can debug it more efficiently, but when I map an integration like
