Cloudflare DNS Provider

This is a drop-in provider for apnscp to enable DNS support for accounts that use Cloudflare. This provider is built into apnscp.

Configuring

EditDomain -c dns,provider=cloudflare -c dns,key='[key:abcdef012456789,email:foo@bar.com,proxy:false]' domain.com

Where the key is created within Cloudflare. See Where do I find my Cloudflare API key. email and key are mandatory variables.

• proxy (true/false)- optionally set all records created to proxy through CF, i.e. be behind CF's IP address.
• jumpstart (true/false)- imports records based on Cloudflare scan

Using API tokens

An restrictive API token may be used instead of the API key that grants unrestricted access to one's account. When creating an API token in Cloudflare, ensure that Zone.Zone and Zone.DNS privileges are enabled with edit access. This token may be specified on a line by itself or mixed with additional options:

EditDomain -c dns,provider=cloudflare -c dns,key='[key:WgBu1xfXP6wvR-ABcDe_ff,proxy:false]' domain.com
# may also be referenced as...
EditDomain -c dns,provider=cloudflare -c dns,key='WgBu1xfXP6wvR-ABcDe_ff' domain.com

Setting as default

Cloudflare may be configured as the default provider for all sites using the dns.default-provider Scope. When adding a site in Nexus or AddDomain the key will be replaced with "DEFAULT". This is substituted automatically on account creation.

In a multi-user environment, Keyring usage is necessary to protect users from accessing the password. When setting this value using the dns.default-provider-key in 3.2.42+, this value is automatically encoded as a Keyring value. Automatic wrapping as a Keyring object may be altered by changing [auth] => keyring_provider_types.

cpcmd scope:set dns.default-provider cloudflare
# Note, this method is insecure prior to 3.2.42, see below!
cpcmd scope:set dns.default-provider-key '[key:abcdef0123456789,email:foo@bar.com,proxy:false]'

::: warning Note that it is not safe to set this value directly in config.ini as a server-wide default in untrusted multiuser environments. A user with panel access can retrieve your key common_get_service_value dns key or even using Javascript in the panel, apnscp.cmd('common_get_service_value',['dns','key'], {async: false}).

Implicit Keyring encoding masks the actual value using a server secret. :::

::: tip This module provides another safe location for a global key setting in config/auth.yaml. See the following section for details. :::

Safely setting global default

Cloudflare settings may be located in config/auth.yaml, which is outside the visibility of site owners. Global settings will be used only if dns,key is set to null/None. All other values are broken out as separate fields, that is to say key must be scalar and may not be an inline complex type ([key:val,key2:val2]).

cloudflare:
  key: "xnYaOGNVFc-nx2QsBkak-A_EjmHdVhZceSqLB7ty"
  proxy: true

or alternatively,

cloudflare:
  key: "abcdef"
  email: 'me@mydomain.com'
  proxy: true

After making changes restart ApisCP to recompile configuration, systemctl restart apiscp. When adding a site, omit dns,key. If dns.default-provider-key is set, then this value must be explicitly passed as null (or "None"). If dns.default-provider-key is not set, then this value may be omitted.

Once set, a site may be added through Nexus or the command-line as follows,

AddDomain -c siteinfo,domain=sometest.com -c dns,provider=cloudflare -c dns,key=None

Components

• Module- overrides Dns_Module behavior
• Validator- service validator, checks input with AddDomain/EditDomain helpers

Minimal module methods

All module methods can be overwritten. The following are the bare minimum that are overwritten for this DNS provider to work:

• atomicUpdate() attempts a record modification, which must retain the original record if it fails
• zoneAxfr() returns all DNS records
• add_record() add a DNS record
• remove_record() removes a DNS record
• get_hosting_nameservers() returns nameservers for the DNS provider
• add_zone_backend() creates DNS zone
• remove_zone_backend() removes a DNS zone
