community.crypto.acme_account module – Create, modify or delete ACME accounts

Note

This module is part of the community.crypto collection (version 2.3.2).

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_account.

Synopsis

  • Allows to create, modify or delete accounts with a CA supporting the ACME protocol, such as Let’s Encrypt.

  • This module only works with the ACME v2 protocol.

Requirements

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

Parameters

Parameter

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

aliases: account_key

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 requisite (cryptography) is 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.

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 / required

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.

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.

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.

The notes for this module contain a list of ACME services this module has been tested against.

acme_version

integer / required

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 value 1 is deprecated since community.crypto 2.0.0 and will be removed from community.crypto 3.0.0.

Choices:

  • 1

  • 2

allow_creation

boolean

Whether account creation is allowed (when state is present).

Choices:

  • no

  • yes ← (default)

contact

list / elements=string

A list of contact URLs.

Email addresses must be prefixed with mailto:.

See https://tools.ietf.org/html/rfc8555#section-7.3 for what is allowed.

Must be specified when state is present. Will be ignored if state is absent or changed_key.

Default: []

external_account_binding

dictionary

added in 1.1.0 of community.crypto

Allows to provide external account binding data during account creation.

This is used by CAs like Sectigo to bind a new ACME account to an existing CA-specific account, to be able to properly identify a customer.

Only used when creating a new account. Can not be specified for ACME v1.

alg

string / required

The MAC algorithm provided by the CA.

If not specified by the CA, this is probably HS256.

Choices:

  • HS256

  • HS384

  • HS512

key

string / required

Base64 URL encoded value of the MAC key provided by the CA.

Padding (= symbols at the end) can be omitted.

kid

string / required

The key identifier provided by the CA.

new_account_key_content

string

Content of the ACME account RSA or Elliptic Curve key to change to.

Same restrictions apply as to account_key_content.

Mutually exclusive with new_account_key_src.

Required if new_account_key_src is not used and state is changed_key.

new_account_key_passphrase

string

added in 1.6.0 of community.crypto

Phassphrase to use to decode the new account key.

Note: this is not supported by the openssl backend, only by the cryptography backend.

new_account_key_src

path

Path to a file containing the ACME account RSA or Elliptic Curve key to change to.

Same restrictions apply as to account_key_src.

Mutually exclusive with new_account_key_content.

Required if new_account_key_content is not used and state is changed_key.

request_timeout

integer

added in 2.3.0 of community.crypto

The time Ansible should wait for a response from the ACME API.

This timeout is applied to all HTTP(S) requests (HEAD, GET, POST).

Default: 10

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.

Choices:

  • auto ← (default)

  • cryptography

  • openssl

state

string / required

The state of the account, to be identified by its account key.

If the state is absent, the account will either not exist or be deactivated.

If the state is changed_key, the account must exist. The account key will be changed; no other information will be touched.

Choices:

  • present

  • absent

  • changed_key

terms_agreed

boolean

Boolean indicating whether you agree to the terms of service document.

ACME servers can require this to be true.

Choices:

  • no ← (default)

  • yes

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.

Choices:

  • no

  • yes ← (default)

Notes

Note

  • The community.crypto.acme_certificate module also allows to do basic account management. When using both modules, it is recommended to disable account management for community.crypto.acme_certificate. For that, use the modify_account option of community.crypto.acme_certificate.

  • If a new enough version of the cryptography library is available (see Requirements for details), it will be used instead of the openssl binary. This can be explicitly disabled or enabled with the select_crypto_backend option. Note that using the openssl binary will be slower and less secure, as private key contents always have to be stored on disk (see account_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.

  • So far, the ACME modules have only been tested by the developers against Let’s Encrypt (staging and production), Buypass (staging and production), ZeroSSL (production), and Pebble testing server. We have got community feedback that they also work with Sectigo ACME Service for InCommon. 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.
