The original body of the issue is below. Cannot create the domain because the certificate has to be from us-east-1 per documentation my stack is in eu-center Virginia region.

ACM Certificates in this region that are associated with a CloudFront distribution are distributed to all the geographic locations configured for that distribution. You should be able to do this by specifying a second provider block and using an alias. This is described briefly in the provider docs. Uff thats awesome I didn't see the provider aliasing. Very helpful thanks, that solved it.

It wouldn't let me assign the certificate to a domain that was being created with the default aws provider in a different region. This looks like it was resolved with using aliased providers and resources pointing to us-east-1 so I'm going to close this, but please don't hesitate if I missed something here.

Here's the second part of my question, I am trying to configure Route 53 for the Regional Custom Domain Name configuration, but I can't find any examples about the right way to do it just for Edge Optimized Custom Domain Name. I tried to create an A record for api. This thread was moved to the AWS Forums here. This endpoint is managed by API Gateway. If anyone wants to understand what was going on with API Gateway, take a look at this thread.

Learn more. Asked 2 years, 7 months ago. Active 2 years, 5 months ago. Viewed 5k times. The result is a Target Domain Name in the form of: aaaaaaaaaaaa. What am I doing wrong?

Active Oldest Votes. Thanks, Jack. Thank you so much for being here! No one answered me on the forums. This was driving me crazy I will try the CLI then. There's one thing I don't understand then I did on R53 and it doesn't work But for what you said and for what the docs say, it would work for an external DNS service What's the difference? Isn't R53 a DNS service after all? Two more things I would like to add: 1 - Please update the docs to make this limitation more explicit.

Jack, could you please answer my forum question? The Route 53 part of my question is answered by Jack and I have nothing to add. I read through that entire thread I was having the same exact issue and this helped save me from going down a rabbit hole for a day or two.

Yes, it was exhausting and I felt kinda helpless, I was pulling my hairs out, that's why I wanted to post it, so someone else wouldn't be as lost as I was, since AWS wasn't making much of an effort to help me. I am glad you could work it out. If you are using the serverless Java container, be sure to check the docs, where it shows how to deal with extracting base path strings github.

Further, these hostnames will change if you remove and redeploy your service, which can cause problems for existing clients. This post is the first in a two-part series. Check out the next post to configure multiple Serverless services on the same domain name for maximum microservice awesomeness. To get started, you'll need the Serverless Framework installed.

You should also have your desired domain name registered through AWS. Read the documentation on that here. The steps below walk through setting up a certificate for your domain. If you already have a certificate issued, skip to the next section. Best of all, it's free!

First, make sure you have the domain name in your Registered Domains in Route If you have a domain that's registered with a different registrar, you can transfer registration to Route If you don't have a domain yet, you can purchase one through Route Note that you'll need to be in region us-east This is the only region that works with API Gateway.

Add the domain name you want, then hit Review and Request. After you confirm, it will say that a confirmation email has been sent to the registered owner of the domain to confirm the certificate. At this point, the certificate will be in a "Pending validation" status. The registered owner of your domain will get a confirmation email from AWS.

How to Set Up a Custom Domain for AWS’s API Gateway

Click the link in the email to confirm issuance of the certificate. Once you do that, the certificate will change to an "Issued" status. Your certificate is ready to go! Move on to the next step to create a custom domain in API Gateway. Before you go any further, you should have a Serverless service with at least one function that has an HTTP event trigger.

If you don't have that, you can use the code below. This example is in Python, but any runtime will work. We've created two simple functions, hello and goodbyeto demonstrate how to write HTTP handlers in Serverless.This article has been updated to use the new Azure PowerShell Az module. You can still use the AzureRM module, which will continue to receive bug fixes until at least December If you don't have an Azure subscriptioncreate a free account before you begin.

This article covers how to use a single API Management service for both internal and external consumers and make it act as a single frontend for both on premises and cloud APIs. You will also see how to expose only a subset of your APIs in the example they are highlighted in green for External Consumption using routing functionality available in Application Gateway.

Internal consumers highlighted in orange can access all your internal and external APIs. Traffic never goes out to the internet. High performance connectivity is delivered via Express Route circuits. In this guide we will also expose the developer portal to external audiences through the Application Gateway. It requires additional steps to create developer portal's listener, probe, settings and rules.

All details are provided in respective steps. If you use Azure AD or third party authentication, please enable cookie-based session affinity feature in Application Gateway. Azure Resource Manager requires that all resource groups specify a location. This is used as the default location for resources in that resource group.

Make sure that all commands to create an application gateway use the same resource group. Assign the address range Use the prefix This step may take more than half an hour. The new developer portal also requires enabling connectivity to the API Management's management endpoint in addition to the steps below. Initialize the following variables with the details of the certificates with private keys for the domains.

In this example, we will use api. All configuration items must be set up before creating the application gateway. The following steps create the configuration items that are needed for an application gateway resource. Create an application gateway IP configuration named gatewayIP When Application Gateway starts, it picks up an IP address from the subnet configured and route network traffic to the IP addresses in the back-end IP pool. Keep in mind that each instance takes one IP address.

Configure the front-end IP port for the public IP endpoint. This port is the port that end users connect to. Configure the certificates for the Application Gateway, which will be used to decrypt and re-encrypt the traffic passing through.

Set api. The hostname contosoapi. Upload the certificate to be used on the TLS-enabled backend pool resources.This causes traffic to be routed to the CloudFront distribution that's associated with the edge-optimized API.

A registered domain name. If you created the hosted zone and the regional endpoint using different accounts, get the target domain name for the custom domain name that you want to use:. Choose the name of the hosted zone that has the domain name that you want to use to route traffic to your API. The API that you want to route traffic to must include a custom domain name, such as api. How you specify the value for Alias Target depends on whether you created the hosted zone and the API using the same AWS account or different accounts:.

The list of target domain names includes only APIs that have a custom domain name that matches the value that you specified for Name. Choose the applicable value. Different accounts — Enter the value that you got in step 1 of this procedure. Choose the applicable routing policy. For more information, see Choosing a routing policy.

When propagation is done, you'll be able to route traffic to your API by using the name of the alias record that you created in this procedure. If you created the Route 53 hosted zone and the regional endpoint using the same account, skip to step 2. Same account — Choose the list, and find the category CloudFront distributions. The list of target domain names includes only distributions that have a custom domain name that matches the value that you specified for Name.

Different accounts — Enter the value that you got in steps 1a through 1c of this procedure. When propagation is done, you can route traffic to your API by using the name of the alias record that you created in this procedure. Javascript is disabled or is unavailable in your browser.

And hard to debug. And while the tooling could be better I tried and struck out at finding a VS Code extension that can validate CF references the fact is, both the CloudFormation implementors and we users of it have some hard problems to solve. Including comments, this CF template is over lines, longer than the code in the Lambda function it deploys.

Brace yourself. Unfortunately, I quickly learned that one-time setup is tricky to include. CloudFormation has a strong bias towards building and managing deployments that can be torn down again.

Lesson learned: Keep the content of the deployment limited to things you are comfortable deleting. Lesson learned: Accept that there will be places where you have to keep strings consistent manually. While YMMV, for me this was a mistake — I ended up needing to tear down, restructure, and recreate the stacks for the tests far more frequently, and quickly pulled them out of the service template.

Lesson learned: Template the tests or other swim lanes of different speeds separately. In any case, building the pipeline with itself is too meta to work, so you have to stand that up first, then use it for your real application deployment. Ok, enough preliminary stuff. The Transform section is pretty straightforward; just remember that the only workable way to get that AWS::CodeStar in there is to let CodeStar generate your template for you.

15 Hours with AWS CloudFormation

These are inserted for us by CodeStar when it creates the project, and enable incremental Lambda deployments. Operational aside: This setting means that, in addition to the overhead of CodeStar, github or CodeCommit if you chose thatCodePipeline, CodeBuild, and CloudFormation, you will also have a minimum of 5 minutes for Lambda canary deployments on each successful deployment.

You may want to turn this setting down or off during development and then reinstate it during production. Yay — our first actual definition! For simple Serverless projects, SAM can save a lot of typing. I prefaced the many items associated with the NAT Puncher with the project name so that I could add things to this template later on without worrying about collisions.

Note that important trailing slash. Layers I chose to package my Python prerequisites into a layer. Whether this is a good idea depends on your development practices. In that phase of design, not having to re-upload the Python dependencies every time I made a little tweak was a huge win. My suggestion is to go through every single object in the ZIP and make sure you truly need it at runtime, rather than just zipping up whatever landed in site-packages. CF runs a topological sort on that DAG to solve for a viable deployment order.

Here I kept it simple by avoiding a spurious additional edge in that graph, at the cost of duplicating the name mangling formula for the DB. YMMV…pick the lesser evil :. Tired yet? Note that easy-to-miss trailing slash on the directory name. But instead I found it incremented the version number while eliminating the previous version.

In a pure SAM template, this can be mostly invisible, but the CodeStar-required complexity causes this to get displayed in all its verbose glory:. AssumeRole This is the boilerplate that every Lambda function needs — permission to run as the role being defined here.

Anyone at AWS have insight into that naming convention? I left constructing a hand-authorized, tightly enveloped custom policy as a future TODO item for this project. The CodeStar transformer is supposed to watch the Lambda function role and automatically manage the permission boundary to accommodate the use of additional resources, at least according to the CodeStar docs.

The idea is to enable flexible development while keeping teams safe from harm, but I found the mechanism to be poorly documented, difficult to bootstrap, and mostly a hindrance to getting things to work, because random parts of your deployment will just silently stop working if they fall outside the permission boundary. Copy-pasting from the AWS docs and blogs will lead to inconsistent results, which is how I got into the state of mismatched partition handling.If you are using custom domain names in Amazon API Gatewayit can be useful to gain insights into requests sent to each custom domain name.

If there is more than one custom domain name mapped to a single API, understanding the quantity and type of requests by domain name may help understand request patterns. In the tutorial, you create a CloudWatch log group for custom access logging. You then enable custom access logging for an API stage associated with a custom domain name.

For this tutorial, use the US East N. In the next steps, the tutorial covers:. Now you enable custom access logging. Select one of the API stages that you invoke through a custom domain name:. Once you enable custom access logging, invoke the API using the custom domain name.

The logs appear in the specified CloudWatch log group shortly after. A sample response in the CloudWatch log stream looks like the following:.

Routing traffic to an Amazon API Gateway API by using your domain name

After setting up the custom access logs, you can query against them to find more insights using the custom domain name. This query returns a list of log entries for the custom domain called test.
