Synopsis

• Prepares certificates for ACME challenges such as tls-alpn-01.
• The raw data is provided by the community.crypto.acme_certificate module, and needs to be converted to a certificate to be used for challenge validation. This module provides a simple way to generate the required certificates.

Requirements

The below requirements are needed on the host that executes this module.

• cryptography >= 1.3

Examples

- name: Create challenges for a given CRT for sample.com
  community.crypto.acme_certificate:
    account_key_src: /etc/pki/cert/private/account.key
    challenge: tls-alpn-01
    csr: /etc/pki/cert/csr/sample.com.csr
    dest: /etc/httpd/ssl/sample.com.crt
  register: sample_com_challenge

- name: Create certificates for challenges
  community.crypto.acme_challenge_cert_helper:
    challenge: tls-alpn-01
    challenge_data: "{{ item.value['tls-alpn-01'] }}"
    private_key_src: /etc/pki/cert/key/sample.com.key
  loop: "{{ sample_com_challenge.challenge_data | dictsort }}"
  register: sample_com_challenge_certs

- name: Install challenge certificates
  # We need to set up HTTPS such that for the domain,
  # regular_certificate is delivered for regular connections,
  # except if ALPN selects the "acme-tls/1"; then, the
  # challenge_certificate must be delivered.
  # This can for example be achieved with very new versions
  # of NGINX; search for ssl_preread and
  # ssl_preread_alpn_protocols for information on how to
  # route by ALPN protocol.
  ...:
    domain: "{{ item.domain }}"
    challenge_certificate: "{{ item.challenge_certificate }}"
    regular_certificate: "{{ item.regular_certificate }}"
    private_key: /etc/pki/cert/key/sample.com.key
  loop: "{{ sample_com_challenge_certs.results }}"

- name: Create certificate for a given CSR for sample.com
  community.crypto.acme_certificate:
    account_key_src: /etc/pki/cert/private/account.key
    challenge: tls-alpn-01
    csr: /etc/pki/cert/csr/sample.com.csr
    dest: /etc/httpd/ssl/sample.com.crt
    data: "{{ sample_com_challenge }}"
