How to create self-signed certificates
|
|
======================================
|
|
|
|
The `community.crypto collection <https://galaxy.ansible.com/ui/repo/published/community/crypto/>`_ offers multiple modules that create private keys, certificate signing requests, and certificates. This guide shows how to create self-signed certificates.
|
|
|
|
For creating any kind of certificate, you always have to start with a private key. You can use the :ref:`community.crypto.openssl_privatekey module <ansible_collections.community.crypto.openssl_privatekey_module>` to create a private key. If you only specify :ansopt:`community.crypto.openssl_privatekey#module:path`, the default parameters will be used. This will result in a 4096 bit RSA private key:
|
|
|
|
.. code-block:: yaml+jinja
|
|
|
|
- name: Create private key (RSA, 4096 bits)
|
|
community.crypto.openssl_privatekey:
|
|
path: /path/to/certificate.key
|
|
|
|
You can specify :ansopt:`community.crypto.openssl_privatekey#module:type` to select another key type, :ansopt:`community.crypto.openssl_privatekey#module:size` to select a different key size (only available for RSA and DSA keys), or :ansopt:`community.crypto.openssl_privatekey#module:passphrase` if you want to store the key password-protected:
|
|
|
|
.. code-block:: yaml+jinja
|
|
|
|
- name: Create private key (X25519) with password protection
|
|
community.crypto.openssl_privatekey:
|
|
path: /path/to/certificate.key
|
|
type: X25519
|
|
passphrase: changeme
|
|
|
|
To create a very simple self-signed certificate with no specific information, you can proceed directly with the :ref:`community.crypto.x509_certificate module <ansible_collections.community.crypto.x509_certificate_module>`:
|
|
|
|
.. code-block:: yaml+jinja
|
|
|
|
- name: Create simple self-signed certificate
|
|
community.crypto.x509_certificate:
|
|
path: /path/to/certificate.pem
|
|
privatekey_path: /path/to/certificate.key
|
|
provider: selfsigned
|
|
|
|
(If you used :ansopt:`community.crypto.openssl_privatekey#module:passphrase` for the private key, you have to provide :ansopt:`community.crypto.x509_certificate#module:privatekey_passphrase`.)
|
|
|
|
You can use :ansopt:`community.crypto.x509_certificate#module:selfsigned_not_after` to define when the certificate expires (default: in roughly 10 years), and :ansopt:`community.crypto.x509_certificate#module:selfsigned_not_before` to define from when the certificate is valid (default: now).
|
|
|
|
To define further properties of the certificate, like the subject, Subject Alternative Names (SANs), key usages, name constraints, etc., you need to first create a Certificate Signing Request (CSR) and provide it to the :ref:`community.crypto.x509_certificate module <ansible_collections.community.crypto.x509_certificate_module>`. If you do not need the CSR file, you can use the :ref:`community.crypto.openssl_csr_pipe module <ansible_collections.community.crypto.openssl_csr_pipe_module>` as in the example below. (To store it to disk, use the :ref:`community.crypto.openssl_csr module <ansible_collections.community.crypto.openssl_csr_module>` instead.)
|
|
|
|
.. code-block:: yaml+jinja
|
|
|
|
- name: Create certificate signing request (CSR) for self-signed certificate
|
|
community.crypto.openssl_csr_pipe:
|
|
privatekey_path: /path/to/certificate.key
|
|
common_name: ansible.com
|
|
organization_name: Ansible, Inc.
|
|
subject_alt_name:
|
|
- "DNS:ansible.com"
|
|
- "DNS:www.ansible.com"
|
|
- "DNS:docs.ansible.com"
|
|
register: csr
|
|
|
|
- name: Create self-signed certificate from CSR
|
|
community.crypto.x509_certificate:
|
|
path: /path/to/certificate.pem
|
|
csr_content: "{{ csr.csr }}"
|
|
privatekey_path: /path/to/certificate.key
