Terraform-Cloudflare-Maintenance
Terraform module to create a responsive Maintenance Page using Cloudflare Workers.
The Cloudflare script intercepts all incoming requests and checks if the request is coming from an IP that is in the whitelist or if the request path matches a whitelisted path. If the request is not whitelisted, it returns a maintenance page.
The module can be used through Terraform's registry.

Usage
A detailed explanation of the implementation can be found here.
Export cloudflare credentials
TF_VAR_cloudflare_email=xxx
TF_VAR_cloudflare_api_key=xxx
TF_VAR_cloudflare_account_id=xxx
If using a token, make sure it has all the necessary permissions
Simple maintenance page with your logo, fav icon, company name, font and email with multiple routes on the same domain:
module "hodovi_cc_maintenance" {
source = "git::git@github.com:adinhodovic/terraform-cloudflare-maintenance.git?ref=0.7.0"
cloudflare_zone = "hodovi.cc"
patterns = ["hodovi.cc/maintenance/*", "hodovi.cc/example/*"]
company_name = "HoneyLogic"
email = "support@honeylogic.io"
statuspage_url = "https://status.hodovi.cc"
font = "Poppins"
logo_url = "https://s3.eu-west-1.amazonaws.com/honeylogic.io/media/images/Honeylogic-blue.original.png"
favicon_url = "https://s3.eu-west-1.amazonaws.com/honeylogic.io/media/images/Honeylogic_-_icon.original.height-80.png"
}
Use the enabled flag to enable/disable the Cloudflare route when maintenance starts/ends:
module "hodovi_cc_maintenance" {
source = "git::git@github.com:adinhodovic/terraform-cloudflare-maintenance.git?ref=0.7.0"
enabled = false
cloudflare_zone = "hodovi.cc"
patterns = ["hodovi.cc/maintenance/*"]
company_name = "HoneyLogic"
email = "support@honeylogic.io"
statuspage_url = "null"
font = "Poppins"
logo_url = "https://s3.eu-west-1.amazonaws.com/honeylogic.io/media/images/Honeylogic-blue.original.png"
favicon_url = "https://s3.eu-west-1.amazonaws.com/honeylogic.io/media/images/Honeylogic_-_icon.original.height-80.png"
}
