community.crypto.acme_inspect – Send direct requests to an ACME server
Note
This plugin is part of the community.crypto collection (version 1.9.6).
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.
To use it in a playbook, specify: community.crypto.acme_inspect.
Synopsis
- Allows to send direct requests to an ACME server with the ACME protocol, which is supported by CAs such as Let’s Encrypt.
 - This module can be used to debug failed certificate request attempts, for example when community.crypto.acme_certificate fails or encounters a problem which you wish to investigate.
 - The module can also be used to directly access features of an ACME servers which are not yet supported by the Ansible ACME modules.
 
Requirements
The below requirements are needed on the host that executes this module.
- python >= 2.6
 - either openssl or cryptography >= 1.5
 
Parameters
| Parameter | Choices/Defaults | Comments | 
|---|---|---|
| account_key_content
        
        string
         | 
      
        
        Content of the ACME account RSA or Elliptic Curve key.
        
       
        Mutually exclusive with  
       account_key_src.
       
        Required if  
       account_key_src is not used.
       
        Warning: the content will be written into a temporary file, which will be deleted by Ansible when the module completes. Since this is an important private key — it can be used to change the account key, or to revoke your certificates without knowing their private keys —, this might not be acceptable.
        
       
        In case  cryptography is used, the content is not written into a temporary file. It can still happen that it is written to disk by Ansible in the process of moving the module with its argument to the node where it is executed.
        | 
     |
| account_key_passphrase
        
        string
        
       
        added in 1.6.0 of community.crypto
         | 
      
        
        Phassphrase to use to decode the account key.
        
       
        Note: this is not supported by the  openssl backend, only by the cryptography backend.
        | 
     |
| account_key_src
        
        path
         | 
      
        
        Path to a file containing the ACME account RSA or Elliptic Curve key.
        
       
        Private keys can be created with the community.crypto.openssl_privatekey or community.crypto.openssl_privatekey_pipe modules. If the requisites (pyOpenSSL or cryptography) are not available, keys can also be created directly with the  
       openssl command line tool: RSA keys can be created with openssl genrsa .... Elliptic curve keys can be created with openssl ecparam -genkey .... Any other tool creating private keys in PEM format can be used as well.
       
        Mutually exclusive with  
       account_key_content.
       
        Required if  
       account_key_content is not used.
       aliases: account_key  | 
     |
| account_uri
        
        string
         | 
      
        
        If specified, assumes that the account URI is as given. If the account key does not match this account, or an account with this URI does not exist, the module fails.
         | 
     |
| acme_directory
        
        string
         | 
      
        
        The ACME directory to use. This is the entry point URL to access the ACME CA server API.
        
       
        For safety reasons the default is set to the Let's Encrypt staging server (for the ACME v1 protocol). This will create technically correct, but untrusted certificates.
        
       
        The default value is  
       https://acme-staging.api.letsencrypt.org/directory. Note that in community.crypto 2.0.0, this option will be required and will no longer have a default. Note that the default is the Let's Encrypt staging server for the ACME v1 protocol, which is deprecated and will be disabled in May 2021 (see here for details).
       
        For Let's Encrypt, all staging endpoints can be found here: https://letsencrypt.org/docs/staging-environment/. For Buypass, all endpoints can be found here: https://community.buypass.com/t/63d4ay/buypass-go-ssl-endpoints
        
       
        For Let's Encrypt, the production directory URL for ACME v2 is https://acme-v02.api.letsencrypt.org/directory. (The production directory URL for ACME v1 is https://acme-v01.api.letsencrypt.org/directory and will be disabled in July 2021.)
        
       
        For Buypass, the production directory URL for ACME v2 and v1 is https://api.buypass.com/acme/directory.
        
       
        For ZeroSSL, the production directory URL for ACME v2 is https://acme.zerossl.com/v2/DV90.
        
       
        Warning: So far, the ACME modules have only been tested against Let's Encrypt (staging and production), Buypass (staging and production), ZeroSSL (production), and Pebble testing server. If you experience problems with another ACME server, please create an issue to help us supporting it. Feedback that an ACME server not mentioned does work is also appreciated.
         | 
     |
| acme_version
        
        integer
         | 
      
       
  | 
      
        
        The ACME version of the endpoint.
        
       
        Must be  
       1 for the classic Let's Encrypt and Buypass ACME endpoints, or 2 for standardized ACME v2 endpoints.
       
        The default value is  
       1. Note that in community.crypto 2.0.0, this option will be required and will no longer have a default.
       
        Please also note that we will deprecate ACME v1 support eventually.
         | 
     
| content
        
        string
         | 
      
        
        An encoded JSON object which will be sent as the content if method is  
       post.
       
        Required when method is  post, and not allowed otherwise.
        | 
     |
| fail_on_acme_error
        
        boolean
         | 
      
       
  | 
      
        
        If method is  post or get, make the module fail in case an ACME error is returned.
        | 
     
| method
        
        string
         | 
      
       
  | 
      
        
        The method to use to access the given URL on the ACME server.
        
       
        The value  
       post executes an authenticated POST request. The content must be specified in the content option.
       
        The value  
       get executes an authenticated POST-as-GET request for ACME v2, and a regular GET request for ACME v1.
       
        The value  directory-only only retrieves the directory, without doing a request.
        | 
     
| select_crypto_backend
        
        string
         | 
      
       
  | 
      
        
        Determines which crypto backend to use.
        
       
        The default choice is  
       auto, which tries to use cryptography if available, and falls back to openssl.
       
        If set to  
       openssl, will try to use the openssl binary.
       
        If set to  cryptography, will try to use the cryptography library.
        | 
     
| url
        
        string
         | 
      
        
        The URL to send the request to.
        
       
        Must be specified if method is not  directory-only.
        | 
     |
| validate_certs
        
        boolean
         | 
      
       
  | 
      
        
        Whether calls to the ACME directory will validate TLS certificates.
        
       
        Warning: Should only ever be set to  no for testing purposes, for example when testing against a local Pebble server.
        | 
     
Notes
Note
- The account_uri option must be specified for properly authenticated ACME v2 requests (except a 
new-accountrequest). - Using the 
ansibletool, community.crypto.acme_inspect can be used to directly execute ACME requests without the need of writing a playbook. For example, the following command retrieves the ACME account with ID 1 from Let’s Encrypt (assuming/path/to/keyis the correct private account key):ansible localhost -m acme_inspect -a "account_key_src=/path/to/key acme_directory=https://acme-v02.api.letsencrypt.org/directory acme_version=2 account_uri=https://acme-v02.api.letsencrypt.org/acme/acct/1 method=get url=https://acme-v02.api.letsencrypt.org/acme/acct/1" - If a new enough version of the 
cryptographylibrary is available (see Requirements for details), it will be used instead of theopensslbinary. This can be explicitly disabled or enabled with theselect_crypto_backendoption. Note that using theopensslbinary will be slower and less secure, as private key contents always have to be stored on disk (seeaccount_key_content). - Although the defaults are chosen so that the module can be used with the Let’s Encrypt CA, the module can in principle be used with any CA providing an ACME endpoint, such as Buypass Go SSL.
