This is an ansible script that I was expecting to print out the same random number three times. Instead, it prints out three random numbers. How do I assign a random number to a variable in ansible so that it is fixed throughout the playbook?
- This module allows one to (re)generate OpenSSL private keys.
- One can generate RSA, DSA, ECC or EdDSA private keys.
- Keys are generated in PEM format.
- Please note that the module regenerates private keys if they don’t match the module’s options. In particular, if you provide another passphrase (or specify none), change the keysize, etc., the private key will be regenerated. If you are concerned that this could overwrite your private key, consider using the backup option.
- The module can use the cryptography Python library, or the pyOpenSSL Python library. By default, it tries to detect which one is available. This can be overridden with the select_crypto_backend option. Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13.”
The below requirements are needed on the host that executes this module.
Just practicing with some custom modules. I can't really think of anything useful to write because there are so many already, so I just made a random string generator that can be passed into a variable for other tasks. Here's the output: Here's the modul. Create a new vars/ directory with a vars.yml file inside. Now, copy all of the variables, add the -, paste them here, and - you know the drill - un-indent them: 6 lines ansible/vars/vars.yml. The password lookup will generate a new random password each time', thus the current behaviour is at least confusing and unexpected. From irc: Richlv: Whatever is happening seems to be happening at a higher level than the password lookup plugin: as far as I.

- Either cryptography >= 1.2.3 (older versions might work as well)
- Or pyOpenSSL
Parameter | Choices/Defaults | Comments |
---|---|---|
attributes string | The attributes the resulting file or directory should have. To get supported flags look at the man page for chattr on the target system. This string should contain the attributes in the same order as the one displayed by lsattr. The = operator is assumed as default, otherwise + or - operators need to be included in the string. | |
backup added in 2.8 |
| Create a backup file including a timestamp so you can get the original private key back if you overwrote it with a new one by accident. |
cipher string | The cipher to encrypt the private key. (Valid values can be found by running `openssl list -cipher-algorithms` or `openssl list-cipher-algorithms`, depending on your OpenSSL version.) | |
curve added in 2.8 |
| Note that not all curves are supported by all versions of cryptography .For maximal interoperability, secp384r1 or secp256r1 should be used.We use the curve names as defined in the IANA registry for TLS. |
force boolean |
| Should the key be regenerated even if it already exists. |
group string | Name of the group that should own the file/directory, as would be fed to chown. | |
mode string | The permissions the resulting file or directory should have. For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777 ) or quote it (like '644' or '1777' ) so Ansible receives a string and can do its own conversion from string into number.Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results. As of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r ).As of Ansible 2.6, the mode may also be the special string preserve .When set to preserve the file will be given the same permissions as the source file. | |
owner string | Name of the user that should own the file/directory, as would be fed to chown. | |
passphrase string | The passphrase for the private key. | |
path path / required | Name of the file in which the generated TLS/SSL private key will be written. It will have 0600 mode. | |
select_crypto_backend string |
| The default choice is auto , which tries to use cryptography if available, and falls back to pyopenssl .If set to pyopenssl , will try to use the pyOpenSSL library.If set to cryptography , will try to use the cryptography library.Please note that the pyopenssl backend has been deprecated in Ansible 2.9, and will be removed in Ansible 2.13. From that point on, only the cryptography backend will be available. |
selevel string | Default: | The level part of the SELinux file context. This is the MLS/MCS attribute, sometimes known as the range .When set to _default , it will use the level portion of the policy if available. |
serole string | When set to _default , it will use the role portion of the policy if available. | |
setype string | When set to _default , it will use the type portion of the policy if available. | |
seuser string | By default it uses the system policy, where applicable.When set to _default , it will use the user portion of the policy if available. | |
size integer | Default: | Size (in bits) of the TLS/SSL key to generate. |
state string |
| Whether the private key should exist or not, taking action if the state is different from what is stated. |
type string |
| The algorithm used to generate the TLS/SSL private key. Note that ECC , X25519 , X448 , Ed25519 and Ed448 require the cryptography backend. X25519 needs cryptography 2.5 or newer, while X448 , Ed25519 and Ed448 require cryptography 2.6 or newer. For ECC , the minimal cryptography version required depends on the curve option. |
unsafe_writes boolean |
| Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file. By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner. This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail (however, it doesn't force Ansible to perform unsafe writes). IMPORTANT! Unsafe writes are subject to race conditions and can lead to data corruption. |

Ansible Ssh User Password
- Generates a random plaintext password and stores it in a file at a given filepath.
- If the file exists previously, it will retrieve its contents, behaving just like with_file.
- Usage of variables like
'{{inventory_hostname}}'
in the filepath can be used to set up random passwords per host, which simplifies password management in'host_vars'
variables. - A special case is using /dev/null as a path. The password lookup will generate a new random password each time, but will not write it to /dev/null. This can be used when you need a password without storing it on the controller.
Parameter | Choices/Defaults | Configuration | Comments |
---|---|---|---|
_terms | path to the file that stores/will store the passwords | ||
chars added in 1.4 | Define comma separated list of names that compose a custom character set in the generated passwords. By default generated passwords contain a random mix of upper and lowercase ASCII letters, the numbers 0-9 and punctuation ('. , : - _'). They can be either parts of Python's string module attributes (ascii_letters,digits, etc) or are used literally ( :, -). To enter comma use two commas ',' somewhere - preferably at the end. Quotes and double quotes are not supported. | ||
encrypt | Default: 'None' | Which hash scheme to encrypt the returning password, should be one hash scheme from passlib.hash .If not provided, the password will be returned in plain text. Note that the password is always stored as plain text, only the returning password is encrypted. Encrypt also forces saving the salt value for idempotence. Note that before 2.6 this option was incorrectly labeled as a boolean for a long time. | |
length | Default: 20 |
Note
- A great alternative to the password lookup plugin, if you don’t need to generate random passwords on a per-host basis, would be to use Vault in playbooks. Read the documentation there and consider using it first, it will be more desirable for most applications.
- If the file already exists, no data will be written to it. If the file has contents, those contents will be read in as the password. Empty files cause the password to return as an empty string.
- As all lookups, this runs on the Ansible host as the user running the playbook, and “become” does not apply, the target file must be readable by the playbook user, or, if it does not exist, the playbook user must have sufficient privileges to create it. (So, for example, attempts to write into areas such as /etc will fail unless the entire playbook is being run as root).
