cdist-type__ssh_authorized_keys - Man Page

Manage ssh authorized_keys files

Description

Adds or removes ssh keys from a authorized_keys file.

This type uses the __ssh_dot_ssh type to manage the directory containing the authorized_keys file. You can disable this feature with the --noparent boolean parameter.

The existence, ownership and permissions of the authorized_keys file itself are also managed. This can be disabled with the --nofile boolean parameter. It is then left to the user to ensure that the file exists and that ownership and permissions work with ssh.

Required Multiple Parameters

key

An ssh key which shall be managed in this authorized_keys file. Must be a string containing the ssh keytype, base 64 encoded key and optional trailing comment which shall be added to the given authorized_keys file. Can be specified multiple times.

Optional Parameters

comment

Use this comment instead of the one which may be trailing in each key.

file

An alternative destination file, defaults to ~$owner/.ssh/authorized_keys.

option

An option to set for all authorized_key entries in the key parameter. Can be specified multiple times. See sshd(8) for available options.

owner

The user owning the authorized_keys file, defaults to object_id.

state

If the given keys should be 'present' or 'absent', defaults to 'present'.

Boolean Parameters

noparent

Don't create or change ownership and permissions of the directory containing the authorized_keys file.

nofile

Don't manage existence, ownership and permissions of the the authorized_keys file.

remove-unknown

Remove undefined keys.
