A client software for acme-dns with emphasis on usability and guidance through setup and additional security safeguard mechanisms. It is designed for usage with existing ACME clients with minimal configuration.

• Download a prebuilt binary from releases page, unpack and run!

  or

• If you have recent go compiler installed: go get -u github.com/acme-dns/acme-dns-client (the same command works for updating)

  or

• git clone https://github.com/acme-dns/acme-dns-client ; cd acme-dns-client ; go get ; go build

• acme-dns account pre-registration
• Guided CNAME record creation
• Guided CAA record creation
• Modular ACME client support for CAA record creation guidance (for ACME-CAA accounturi)
• Configuration checks to ensure operation (CNAME record, account exisence)
• Interactive setup

# sudo certbot register

This creates a new ACME account that is used internally by Certbot. In case you are not planning to set up CAA record, this step can be omitted.

# sudo acme-dns-client register -d your.domain.example.org -s https://auth.acme-dns.io

This attempts to create a new account to acme-dns instance running at auth.acme-dns.io. After account creation, the user is guided through proper CNAME record creation for the main DNS zone for domain your.domain.example.org.

Optionally the same will be done for CAA record creation. acme-dns-client will attempt to read the account URL from active Certbot configuration (created in step 1)

acme-dns-client will monitor the DNS record changes to ensure they are set up correctly.

# sudo certbot certonly --manual --preferred-challenges dns \
    --manual-auth-hook 'acme-dns-client' -d your.domain.example.org 

This runs Certbot and instructs it to obtain a new certificate for domain your.domain.example.org by using a DNS challenge and acme-dns-client as the authenticator. After successfully obtaining the new certificate this configuration will be saved in Certbot configuration and will be automatically reused when it renews the certificate.
