Client Applications

We use S3 buckets to host files, and Amazon CloudFront to servce the files.

CloudFront to S3

CloudFront to S3

Minimal working example

The following code creates a client application that will be reachable from https://kattehotell.dev.bymoslo.net:

main.tf
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
module "application" {
  source           = "git@github.com:BYM-IKT/terraform-byks-module.git"
  team             = var.team
  account_id       = var.account_id
  environment      = var.environment
  region           = var.region
  application_name = var.application_name

  cloudfront_distributions = {
    kattehotell = {}
  }

  providers = {
    aws.route53   = aws.route53
    aws.us-east-1 = aws.us-east-1
    aws.ses       = aws.ses
  }
}

Note

The domain resulting is automatically inferred using the value of environment, i.e.: 

`dev`  => `dev.bymoslo.net`
`prod` => `bymoslo.no`

Features

Additional domains

Sometimes we wish to have a client application reachable from multiple URLs. Additional URLs can be added as follows:

main.tf
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18

21
module "application" {
  source      = "git@github.com:BYM-IKT/terraform-byks-module.git"
  environment = "dev"

  # ...

  cloudfront_distributions = {
    kattehotell = {
      additional_domains = [
        {
          domain_name = "hotell-for-katter.dev.bymoslo.net"
          zone_name   = "bymoslo.net"
        },
        {
          domain_name = "www.cat-hotel.no"
          zone_name   = "cat-hotel.no"
        },
      ]
    }
  }
}

This provisions a client application reachable from 3 different URLs:

  • https://kattehotell.dev.bymoslo.net (default)
  • https://hotell-for-katter.dev.bymoslo.net
  • https://cat-hotel.dev.bymoslo.net
