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::[email protected]:adinhodovic/terraform-cloudflare-maintenance.git?ref=v0.6.0"
  cloudflare_zone = "hodovi.cc"
  patterns        = ["hodovi.cc/maintenance/*", "hodovi.cc/example/*"]
  company_name    = "HoneyLogic"
  email           = "[email protected]"
  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::[email protected]:adinhodovic/terraform-cloudflare-maintenance.git?ref=v0.6.0"
  enabled         = false
  cloudflare_zone = "hodovi.cc"
  patterns        = ["hodovi.cc/maintenance/*"]
  company_name    = "HoneyLogic"
  email           = "[email protected]"
  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"
}
