Requirements

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

Parameters

Parameter

Comments

alt_names

list / elements=string

Specifies requested Subject Alternative Names.

These can be host names or email addresses; they will be parsed into their respective fields.

If any requested names do not match role policy, the entire request will be denied.

auth_method

string

Authentication method to be used.

none auth method was added in collection version 1.2.0.

cert auth method was added in collection version 1.4.0.

aws_iam_login was renamed aws_iam in collection version 2.1.0 and was removed in 3.0.0.

Choices:

  • token ← (default)

  • userpass

  • ldap

  • approle

  • aws_iam

  • jwt

  • cert

  • none

aws_access_key

aliases: aws_access_key_id

string

The AWS access key to use.

aws_iam_server_id

string

added in 0.2.0 of community.hashi_vault

If specified, sets the value to use for the X-Vault-AWS-IAM-Server-ID header as part of GetCallerIdentity request.

aws_profile

aliases: boto_profile

string

The AWS profile

aws_secret_key

aliases: aws_secret_access_key

string

The AWS secret key that corresponds to the access key.

aws_security_token

string

The AWS security token if using temporary access and secret keys.

ca_cert

aliases: cacert

string

Path to certificate to use for authentication.

If not specified by any other means, the VAULT_CACERT environment variable will be used.

cert_auth_private_key

path

added in 1.4.0 of community.hashi_vault

For cert auth, path to the private key file to authenticate with, in PEM format.

cert_auth_public_key

path

added in 1.4.0 of community.hashi_vault

For cert auth, path to the certificate file to authenticate with, in PEM format.

common_name

string / required

Specifies the requested CN for the certificate.

If the CN is allowed by role policy, it will be issued.

engine_mount_point

string

Specify the mount point used by the PKI engine.

Defaults to the default used by hvac.

exclude_cn_from_sans

boolean

If true, the given common_name will not be included in DNS or Email Subject Alternate Names (as appropriate).

Useful if the CN is not a hostname or email address, but is instead some human-readable identifier.

Choices:

  • no ← (default)

  • yes

format

string

Specifies the format for returned data.

Can be pem, der, or pem_bundle.

If der, the output is base64 encoded.

If pem_bundle, the certificate field will contain the private key and certificate, concatenated. If the issuing CA is not a Vault-derived self-signed root, this will be included as well.

Choices:

  • pem ← (default)

  • der

  • pem_bundle

ip_sans

list / elements=string

Specifies requested IP Subject Alternative Names.

Only valid if the role allows IP SANs (which is the default).

jwt

string

The JSON Web Token (JWT) to use for JWT authentication to Vault.

mount_point

string

Vault mount point.

If not specified, the default mount point for a given auth method is used.

Does not apply to token authentication.

namespace

string

Vault namespace where secrets reside. This option requires HVAC 0.7.0+ and Vault 0.11+.

Optionally, this may be achieved by prefixing the authentication mount point and/or secret path with the namespace (e.g mynamespace/secret/mysecret).

If environment variable VAULT_NAMESPACE is set, its value will be used last among all ways to specify namespace.

other_sans

list / elements=string

Specifies custom OID/UTF8-string SANs.

These must match values specified on the role in allowed_other_sans.

The format is the same as OpenSSL: <oid>;<type>:<value> where the only current valid type is UTF8.

password

string

Authentication password.

private_key_format

string

Specifies the format for marshaling the private key.

Defaults to der which will return either base64-encoded DER or PEM-encoded DER, depending on the value of format.

The other option is pkcs8 which will return the key marshalled as PEM-encoded PKCS8.

Choices:

  • der ← (default)

  • pkcs8

proxies

raw

added in 1.1.0 of community.hashi_vault

URL(s) to the proxies used to access the Vault service.

It can be a string or a dict.

If it’s a dict, provide the scheme (eg. http or https) as the key, and the URL as the value.

If it’s a string, provide a single URL that will be used as the proxy for both http and https schemes.

A string that can be interpreted as a dictionary will be converted to one (see examples).

You can specify a different proxy for HTTP and HTTPS resources.

If not specified, environment variables from the Requests library are used.

region

string

The AWS region for which to create the connection.

retries

raw

added in 1.3.0 of community.hashi_vault

Allows for retrying on errors, based on the Retry class in the urllib3 library.

This collection defines recommended defaults for retrying connections to Vault.

This option can be specified as a positive number (integer) or dictionary.

If this option is not specified or the number is 0, then retries are disabled.

A number sets the total number of retries, and uses collection defaults for the other settings.

A dictionary value is used directly to initialize the Retry class, so it can be used to fully customize retries.

For detailed information on retries, see the collection User Guide.

retry_action

string

added in 1.3.0 of community.hashi_vault

Controls whether and how to show messages on retries.

This has no effect if a request is not retried.

Choices:

  • ignore

  • warn ← (default)

role_id

string

Vault Role ID or name. Used in approle, aws_iam, and cert auth methods.

For cert auth, if no role_id is supplied, the default behavior is to try all certificate roles and return any one that matches.

role_name

string / required

Specifies the name of the role to create the certificate against.

secret_id

string

Secret ID to be used for Vault AppRole authentication.

timeout

integer

added in 1.3.0 of community.hashi_vault

Sets the connection timeout in seconds.

If not set, then the hvac library’s default is used.

token

string

Vault token. Token may be specified explicitly, through the listed [env] vars, and also through the VAULT_TOKEN env var.

If no token is supplied, explicitly or through env, then the plugin will check for a token file, as determined by token_path and token_file.

The order of token loading (first found wins) is token param -> ansible var -> ANSIBLE_HASHI_VAULT_TOKEN -> VAULT_TOKEN -> token file.

token_file

string

If no token is specified, will try to read the token from this file in token_path.

Default: “.vault-token”

token_path

string

If no token is specified, will try to read the token_file from this path.

token_validate

boolean

added in 0.2.0 of community.hashi_vault

For token auth, will perform a lookup-self operation to determine the token’s validity before using it.

Disable if your token does not have the lookup-self capability.

The default value is true.

The default value will change to false in version 4.0.0.

Choices:

  • no

  • yes

ttl

string

Specifies requested Time To Live.

Cannot be greater than the role’s max_ttl value.

If not provided, the role’s ttl value will be used.

Note that the role values default to system values if not explicitly set.

uri_sans

list / elements=string

Specifies the requested URI Subject Alternative Names.

url

string

URL to the Vault service.

If not specified by any other means, the value of the VAULT_ADDR environment variable will be used.

If VAULT_ADDR is also not defined then an error will be raised.

username

string

Authentication user name.

validate_certs

boolean

Controls verification and validation of SSL certificates, mostly you only want to turn off with self signed ones.

Will be populated with the inverse of VAULT_SKIP_VERIFY if that is set and validate_certs is not explicitly provided.

Will default to true if neither validate_certs or VAULT_SKIP_VERIFY are set.

Choices:

  • no

  • yes
