mode: description: - The permissions the resulting filesystem object should have. - For those used to I(/usr/bin/chmod) remember that modes are actually octal numbers. You must give Ansible enough information to parse them correctly. For consistent results, quote octal numbers (for example, V('644') or V('1777')) so Ansible receives a string and can do its own conversion from string into number. Adding a leading zero (for example, V(0755)) works sometimes, but can fail in loops and some other circumstances. - Giving Ansible a number without following either 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, V(u+rwx) or V(u=rw,g=r,o=r)). - If O(mode) is not specified and the destination filesystem object B(does not) exist, the default C(umask) on the system will be used when setting the mode for the newly created filesystem object. - If O(mode) is not specified and the destination filesystem object B(does) exist, the mode of the existing filesystem object will be used. - Specifying O(mode) is the best way to ensure filesystem objects are created with the correct permissions. See CVE-2020-1736 for further details. type: raw path: description: - Path of the file containing the certificate. required: true type: path type: choices: - host - user description: - Whether the module should generate a host or a user certificate. - Required if I(state) is C(present). type: str force: default: false description: - Should the certificate be regenerated even if it already exists and is valid. type: bool group: description: - Name of the group that should own the filesystem object, as would be fed to I(chown). - When left unspecified, it uses the current group of the current user unless you are root, in which case it can preserve the previous ownership. type: str owner: description: - Name of the user that should own the filesystem object, as would be fed to I(chown). - When left unspecified, it uses the current user unless you are root, in which case it can preserve the previous ownership. - Specifying a numeric username will be assumed to be a user ID and not a username. Avoid numeric usernames to avoid this confusion. type: str state: choices: - present - absent default: present description: - Whether the host or user certificate should exist or not, taking action if the state is different from what is stated. type: str serole: description: - The role part of the SELinux filesystem object context. - When set to V(_default), it will use the C(role) portion of the policy if available. type: str setype: description: - The type part of the SELinux filesystem object context. - When set to V(_default), it will use the C(type) portion of the policy if available. type: str seuser: description: - The user part of the SELinux filesystem object context. - By default it uses the V(system) policy, where applicable. - When set to V(_default), it will use the C(user) portion of the policy if available. type: str options: description: - 'Specify certificate options when signing a key. The option that are valid for user certificates are:' - 'C(clear): Clear all enabled permissions. This is useful for clearing the default set of permissions so permissions may be added individually.' - 'C(force-command=command): Forces the execution of command instead of any shell or command specified by the user when the certificate is used for authentication.' - 'C(no-agent-forwarding): Disable ssh-agent forwarding (permitted by default).' - 'C(no-port-forwarding): Disable port forwarding (permitted by default).' - 'C(no-pty Disable): PTY allocation (permitted by default).' - 'C(no-user-rc): Disable execution of C(~/.ssh/rc) by sshd (permitted by default).' - 'C(no-x11-forwarding): Disable X11 forwarding (permitted by default)' - 'C(permit-agent-forwarding): Allows ssh-agent forwarding.' - 'C(permit-port-forwarding): Allows port forwarding.' - 'C(permit-pty): Allows PTY allocation.' - 'C(permit-user-rc): Allows execution of C(~/.ssh/rc) by sshd.' - 'C(permit-x11-forwarding): Allows X11 forwarding.' - 'C(source-address=address_list): Restrict the source addresses from which the certificate is considered valid. The C(address_list) is a comma-separated list of one or more address/netmask pairs in CIDR format.' - At present, no options are valid for host keys. elements: str type: list selevel: description: - The level part of the SELinux filesystem object context. - This is the MLS/MCS attribute, sometimes known as the C(range). - When set to V(_default), it will use the C(level) portion of the policy if available. type: str valid_at: description: - Check if the certificate is valid at a certain point in time. If it is not the certificate will be regenerated. Time will always be interpreted as UTC. Mainly to be used with relative timespec for I(valid_from) and / or I(valid_to). Note that if using relative time this module is NOT idempotent. type: str valid_to: description: - 'The point in time the certificate is valid to. Time can be specified either as relative time or as absolute timestamp. Time will always be interpreted as UTC. Valid formats are: C([+-]timespec | YYYY-MM-DD | YYYY-MM-DDTHH:MM:SS | YYYY-MM-DD HH:MM:SS | forever) where timespec can be an integer + C([w | d | h | m | s]) (e.g. C(+32w1d2h). Note that if using relative time this module is NOT idempotent.' - Required if I(state) is C(present). type: str attributes: aliases: - attr description: - The attributes the resulting filesystem object should have. - To get supported flags look at the man page for I(chattr) on the target system. - This string should contain the attributes in the same order as the one displayed by I(lsattr). - The C(=) operator is assumed as default, otherwise C(+) or C(-) operators need to be included in the string. type: str version_added: '2.3' version_added_collection: ansible.builtin identifier: description: - Specify the key identity when signing a public key. The identifier that is logged by the server when the certificate is used for authentication. type: str principals: description: - Certificates may be limited to be valid for a set of principal (user/host) names. By default, generated certificates are valid for all users or hosts. elements: str type: list public_key: description: - The path to the public key that will be signed with the signing key in order to generate the certificate. - Required if I(state) is C(present). type: path valid_from: description: - 'The point in time the certificate is valid from.

The serial number is logged by the server when the certificate is used for authentication. The certificate serial number may be used in a KeyRevocationList. The serial number may be omitted for checks, but must be specified again for a new certificate. Note: The default value set by ssh-keygen is 0.' type: int unsafe_writes: default: false description: - 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. type: bool version_added: '2.2' version_added_collection: ansible.builtin
