community.general.java_keystore module – Create a Java keystore in JKS format

Note

This module is part of the community.general collection (version 10.7.5).

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.general. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.general.java_keystore.

Synopsis

  • Bundle a x509 certificate and its private key into a Java Keystore in JKS format.

Requirements

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

Parameters

Parameter

Comments

attributes

aliases: attr

string

The attributes the resulting filesystem object 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.

certificate

string

Content of the certificate used to create the keystore.

If the fingerprint of the provided certificate does not match the fingerprint of the certificate bundled in the keystore, the keystore is regenerated with the provided certificate.

Exactly one of certificate or certificate_path is required.

certificate_path

path

added in community.general 3.0.0

Location of the certificate used to create the keystore.

If the fingerprint of the provided certificate does not match the fingerprint of the certificate bundled in the keystore, the keystore is regenerated with the provided certificate.

Exactly one of certificate or certificate_path is required.

dest

path / required

Absolute path of the generated keystore.

force

boolean

Keystore is created even if it already exists.

Choices:

  • false ← (default)

  • true

group

string

Name of the group that should own jks file.

keystore_type

string

added in community.general 3.3.0

Type of the Java keystore.

When this option is omitted and the keystore does not already exist, the behavior follows keytool‘s default store type which depends on Java version; pkcs12 since Java 9 and jks prior (may also be pkcs12 if new default has been backported to this version).

When this option is omitted and the keystore already exists, the current type is left untouched, unless another option leads to overwrite the keystore (in that case, this option behaves like for keystore creation).

When keystore_type is set, the keystore is created with this type if it does not already exist, or is overwritten to match the given type in case of mismatch.

Choices:

  • "jks"

  • "pkcs12"

mode

any

Mode the file should be.

name

string / required

Name of the certificate in the keystore.

If the provided name does not exist in the keystore, the module will re-create the keystore. This behavior changed in community.general 3.0.0, before that the module would fail when the name did not match.

owner

string

Name of the user that should own jks file.

password

string / required

Password that should be used to secure the keystore.

If the provided password fails to unlock the keystore, the module will re-create the keystore with the new passphrase. This behavior changed in community.general 3.0.0, before that the module would fail when the password did not match.

private_key

string

Content of the private key used to create the keystore.

Exactly one of private_key or private_key_path is required.

private_key_passphrase

string

added in community.general 0.2.0

Passphrase used to read the private key, if required.

private_key_path

path

added in community.general 3.0.0

Location of the private key used to create the keystore.

Exactly one of private_key or private_key_path is required.

selevel

string

The level part of the SELinux filesystem object 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

The role part of the SELinux filesystem object context.

When set to _default, it will use the role portion of the policy if available.

setype

string

The type part of the SELinux filesystem object context.

When set to _default, it will use the type portion of the policy if available.

seuser

string

The user part of the SELinux filesystem object context.

By default it uses the system policy, where applicable.

When set to _default, it will use the user portion of the policy if available.

ssl_backend

string

added in community.general 3.1.0

Backend for loading private keys and certificates.

Choices:

  • "openssl" ← (default)

  • "cryptography"

unsafe_writes

boolean

Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target filesystem object.

By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target filesystem objects, but sometimes systems are configured or just broken in ways that prevent this. One example is docker mounted filesystem objects, 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 filesystem objects 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.

Choices:

  • false ← (default)

  • true

Attributes

Attribute

Support

Description

check_mode

Support: full

Can run in check_mode and return changed status prediction without modifying target.

diff_mode

Support: none

Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.
