community.crypto.certificate_complete_chain module – Complete certificate chain given a set of untrusted and root certificates
Note
This module is part of the community.crypto collection (version 2.22.1).
You might already have this collection installed if you are using the ansible
package.
It is not included in ansible-core
.
To check whether it is installed, run ansible-galaxy collection list
.
To install it, use: ansible-galaxy collection install community.crypto
.
You need further requirements to be able to use this module,
see Requirements for details.
To use it in a playbook, specify: community.crypto.certificate_complete_chain
.
Synopsis
This module completes a given chain of certificates in PEM format by finding intermediate certificates from a given set of certificates, until it finds a root certificate in another given set of certificates.
This can for example be used to find the root certificate for a certificate chain returned by community.crypto.acme_certificate.
Note that this module does not check for validity of the chains. It only checks that issuer and subject match, and that the signature is correct. It ignores validity dates and key usage completely. If you need to verify that a generated chain is valid, please use
openssl verify ...
.
Requirements
The below requirements are needed on the host that executes this module.

Parameters
Parameter |
Comments |
---|---|
A concatenated set of certificates in PEM format forming a chain. The module will try to complete this chain. |
|
A list of filenames or directories. A filename is assumed to point to a file containing one or more certificates in PEM format. All certificates in this file will be added to the set of root certificates. If a directory name is given, all files in the directory and its subdirectories will be scanned and tried to be parsed as concatenated certificates in PEM format. Symbolic links will be followed. Default: |

Examples
# Given a leaf certificate for www.ansible.com and one or more intermediate
# certificates, finds the associated root certificate.
- name: Find root certificate
community.crypto.certificate_complete_chain:
input_chain: "{{ lookup('ansible.builtin.file', '/etc/ssl/csr/www.ansible.com-fullchain.pem') }}"
root_certificates:
- /etc/ca-certificates/
register: www_ansible_com
- name: Write root certificate to disk
ansible.builtin.copy:
dest: /etc/ssl/csr/www.ansible.com-root.pem
content: "{{ www_ansible_com.root }}"
# Given a leaf certificate for www.ansible.com, and a list of intermediate
# certificates, finds the associated root certificate.
- name: Find root certificate
community.crypto.certificate_complete_chain:
input_chain: "{{ lookup('ansible.builtin.file', '/etc/ssl/csr/www.ansible.com.pem') }}"
intermediate_certificates:
- /etc/ssl/csr/www.ansible.com-chain.pem
root_certificates:
- /etc/ca-certificates/
register: www_ansible_com
- name: Write complete chain to disk
ansible.builtin.copy:
dest: /etc/ssl/csr/www.ansible.com-completechain.pem
content: "{{ ''.join(www_ansible_com.complete_chain) }}"
- name: Write root chain (intermediates and root) to disk
ansible.builtin.copy:
dest: /etc/ssl/csr/www.ansible.com-rootchain.pem
content: "{{ ''.join(www_ansible_com.chain) }}"
