Step 6 - Hosting the CDN

In this step we will provision hosting of CDN under the client’s domain.

All the below operations are to be performed under the terraform organization created in the step 2.
Setting up the workspace
- Create a workspace with name cdn prefixed with the organization’s environment type. For e.g. if env is prod then the workspace name will be prod-cdn.
- Choose /cdn in the terraform github repository for version control with default branch pointing to master.
- Configure the following variables for the workspace
  1. cdn_domains - (HCL) client’s domain on which CDN is hosted. Replace <domain> with the client’s domain. if domain is cdn.example.com then the variable will be
```
{
    "example.com" = {
      endpoint            = "cdn.example.com"
      dns_map_ack_success = false
    }
}
```
  1. sdk_version - version of SDK to host
Attach this workspace to the respective variable set of the organization created in Step 2.
Run the pipeline by Actions.
- Click on Actions and then Start new run to start a new run.
- Below variables are present in the output
  1. cdn_domains_mappings - DNS authentication for CDN domains
```
[
  {
    "endpoint": "<domain>",
    "record_name": "xxx",
    "record_value": "xxx",
    "type": "CNAME"
  }
]
```
  1. cdn_cloudfront_mappings - DNS authentication to SDK domains. For e.g.
```
[
  {
    "cloudfront_endpoint": "xxx.cloudfront.net",
    "domain ": "<domain>",
    "type": "CNAME"
  }
]
```
The above pipeline creates a SSL/TLS certificate under the client’s domain. This certificate needs to be verified via the DNS strategy.
- Client needs to create a CNAME record with the above record_name and record_value given in the variable output cdn_domains_mapping as name and target respectively.
- Proxy status for the CNAME record should be kept off.
- Create another CNAME record for client’s domain, where the name is domain and target is cloudfront_endpoint as represented in the cdn_cloudfront_mappings. This step points the client’s domain to the cloudfront endpoint.

Edit dns_map_ack_success key in cdn_domains variable to true once the DNS records are in place. Taking the above example -

{
    "example.com" = {
      endpoint            = "cdn.example.com"
      dns_map_ack_success = true
    }
}

Click on Actions and then Start new run to start a new run.
To verify the changes, hit the /index.js endpoint over client’s endpoint. This will give your SDK hosted on CDN.
