See below for supported key types. Not all key types have to be specified, ones left unspecified will not be used. If this config option is used, then no keys will be generated. .. note:: when specifying private keys in cloud-config, care should be taken to ensure that the communication between the data source and the instance is secure .. note:: to specify multiline private keys, use yaml multiline syntax If no keys are specified using ``ssh_keys``, then keys will be generated using ``ssh-keygen``. By default one public/private pair of each supported key type will be generated. The key types to generate can be specified using the ``ssh_genkeytypes`` config flag, which accepts a list of key types to use. For each key type for which this module has been instructed to create a keypair, if a key of the same type is already present on the system (i.e. if ``ssh_deletekeys`` was false), no key will be generated. Supported key types for the ``ssh_keys`` and the ``ssh_genkeytypes`` config flags are: - rsa - dsa - ecdsa - ed25519 Root login can be enabled/disabled using the ``disable_root`` config key. Root login options can be manually specified with ``disable_root_opts``. If ``disable_root_opts`` is specified and contains the string ``$USER``, it will be replaced with the username of the default user. By default, root login is disabled, and root login opts are set to:: no-port-forwarding,no-agent-forwarding,no-X11-forwarding Authorized keys for the default user/first user defined in ``users`` can be specified using ``ssh_authorized_keys``. Keys should be specified as a list of public keys. Importing ssh public keys for the default user (defined in ``users``)) is enabled by default. This feature may be disabled by setting ``allow_publish_ssh_keys: false``. .. note:: see the ``cc_set_passwords`` module documentation to enable/disable ssh password authentication **Internal name:** ``cc_ssh`` **Module frequency:** per instance **Supported distros:** all **Config keys**:: ssh_deletekeys: ssh_keys: rsa_private: | -----BEGIN RSA PRIVATE KEY----- MIIBxwIBAAJhAKD0YSHy73nUgysO13XsJmd4fHiFyQ+00R7VVu2iV9Qco ... -----END RSA PRIVATE KEY----- rsa_public: ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAGEAoPRhIfLvedSDKw7Xd ... dsa_private: | -----BEGIN DSA PRIVATE KEY----- MIIBxwIBAAJhAKD0YSHy73nUgysO13XsJmd4fHiFyQ+00R7VVu2iV9Qco ... -----END DSA PRIVATE KEY----- dsa_public: ssh-dsa AAAAB3NzaC1yc2EAAAABIwAAAGEAoPRhIfLvedSDKw7Xd ... ssh_genkeytypes: disable_root: disable_root_opts: ssh_authorized_keys: - ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAGEA3FSyQwBI6Z+nCSjUU ... - ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA3I7VUf2l5gSn5uavROsc5HRDpZ ... allow_public_ssh_keys: ssh_publish_hostkeys: enabled: (Defaults to true) blacklist: (Defaults to [dsa]) iN(tug_util(tssh_util(tutiltrsatdsatecdsated25519s/etc/ssh/ssh_host_%s_keyis %s_privates.pubs %s_publics;o=$(ssh-keygen -yf "%s") && echo "$o" root@localhost > "%s"c!
