ansible.builtin.ssh – connect via ssh client binary
Note
This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name ssh even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.
Synopsis
- This connection plugin allows ansible to communicate to the target machines via normal ssh command line.
 - Ansible does not expose a channel to allow communication between the user and the ssh process to accept a password manually to decrypt an ssh key when using this connection plugin (which is the default). The use of 
ssh-agentis highly recommended. 
Parameters
| Parameter | Choices/Defaults | Configuration | Comments | 
|---|---|---|---|
|   control_path    string    |     ini entries:    [ssh_connection]  env:ANSIBLE_SSH_CONTROL_PATH    var: ansible_control_path    added in 2.7 of ansible.builtin    |    This is the location to save ssh's ControlPath sockets, it uses ssh's variable substitution.  Since 2.3, if null, ansible will generate a unique hash. Use `%(directory)s` to indicate where to use the control dir path setting.   |  |
|   control_path_dir    string    |   Default: "~/.ansible/cp"   |     ini entries:    [ssh_connection]  env:ANSIBLE_SSH_CONTROL_PATH_DIR    var: ansible_control_path_dir    added in 2.7 of ansible.builtin    |    This sets the directory to use for ssh control path if the control path setting is null.  Also, provides the `%(directory)s` variable for the control path setting.   |  
|   host    string    |   Default: "inventory_hostname"   |     var: ansible_host    var: ansible_ssh_host    |    Hostname/ip to connect to.   |  
|   host_key_checking    boolean    |   
  |     ini entries:    [defaults]  [ssh_connection]  added in 2.5 of ansible.builtin    env:ANSIBLE_HOST_KEY_CHECKING    env:ANSIBLE_SSH_HOST_KEY_CHECKING    added in 2.5 of ansible.builtin    var: ansible_host_key_checking    added in 2.5 of ansible.builtin    var: ansible_ssh_host_key_checking    added in 2.5 of ansible.builtin    |    Determines if ssh should check host keys   |  
|   password    string    |     var: ansible_password    var: ansible_ssh_pass    var: ansible_ssh_password    |    Authentication password for the   remote_user. Can be supplied as CLI option. |  |
|   pipelining    boolean    |   
 "ANSIBLE_PIPELINING"   |     ini entries:    [defaults]  [ssh_connection]  env:ANSIBLE_PIPELINING    env:ANSIBLE_SSH_PIPELINING    var: ansible_pipelining    var: ansible_ssh_pipelining    |    Pipelining reduces the number of SSH operations required to execute a module on the remote server, by executing many Ansible modules without actual file transfer.  This can result in a very significant performance improvement when enabled.  However this conflicts with privilege escalation (become). For example, when using sudo operations you must first disable 'requiretty' in the sudoers file for the target hosts, which is why this feature is disabled by default.   |  
|   port    integer    |   Default: 22   |     ini entries:    [defaults]  env:ANSIBLE_REMOTE_PORT    var: ansible_port    var: ansible_ssh_port    |    Remote port to connect to.   |  
|   private_key_file    string    |     ini entries:    [defaults]  env:ANSIBLE_PRIVATE_KEY_FILE    var: ansible_private_key_file    var: ansible_ssh_private_key_file    |    Path to private key file to use for authentication   |  |
|   remote_user    string    |     ini entries:    [defaults]  env:ANSIBLE_REMOTE_USER    var: ansible_user    var: ansible_ssh_user    |    User name with which to login to the remote server, normally set by the remote_user keyword.  If no user is supplied, Ansible will let the ssh client binary choose the user as it normally   |  |
|   retries    integer    |   Default: 3   |     ini entries:    [connection]  [ssh_connection]  env:ANSIBLE_SSH_RETRIES    var: ansible_ssh_retries    added in 2.7 of ansible.builtin    |    Number of attempts to connect.   |  
|   scp_executable    string    added in 2.6 of ansible.builtin    |   Default: "scp"   |     ini entries:    [ssh_connection]  env:ANSIBLE_SCP_EXECUTABLE    var: ansible_scp_executable    added in 2.7 of ansible.builtin    |    This defines the location of the scp binary. It defaults to `scp` which will use the first binary available in $PATH.   |  
|   scp_extra_args    string    |     ini entries:    [ssh_connection]  added in 2.7 of ansible.builtin    env:ANSIBLE_SCP_EXTRA_ARGS    added in 2.7 of ansible.builtin    var: ansible_scp_extra_args    |    Extra exclusive to the ``scp`` CLI   |  |

|   sftp_batch_mode    boolean    |   
  |     ini entries:    [ssh_connection]  env:ANSIBLE_SFTP_BATCH_MODE    var: ansible_sftp_batch_mode    added in 2.7 of ansible.builtin    |    TODO: write it   |  
|   sftp_executable    string    added in 2.6 of ansible.builtin    |   Default: "sftp"   |     ini entries:    [ssh_connection]  env:ANSIBLE_SFTP_EXECUTABLE    var: ansible_sftp_executable    added in 2.7 of ansible.builtin    |    This defines the location of the sftp binary. It defaults to ``sftp`` which will use the first binary available in $PATH.   |  
|   sftp_extra_args    string    |     ini entries:    [ssh_connection]  added in 2.7 of ansible.builtin    env:ANSIBLE_SFTP_EXTRA_ARGS    added in 2.7 of ansible.builtin    var: ansible_sftp_extra_args    |    Extra exclusive to the ``sftp`` CLI   |  |

|   ssh_common_args    string    |     ini entries:    [ssh_connection]  added in 2.7 of ansible.builtin    env:ANSIBLE_SSH_COMMON_ARGS    added in 2.7 of ansible.builtin    var: ansible_ssh_common_args    |    Common extra args for all ssh CLI tools   |  |
|   ssh_executable    string    added in 2.2 of ansible.builtin    |   Default: "ssh"   |     ini entries:    [ssh_connection]  env:ANSIBLE_SSH_EXECUTABLE    var: ansible_ssh_executable    added in 2.7 of ansible.builtin    |    This defines the location of the ssh binary. It defaults to ``ssh`` which will use the first ssh binary available in $PATH.  This option is usually not required, it might be useful when access to system ssh is restricted, or when using ssh wrappers to connect to remote hosts.   |  
|   ssh_extra_args    string    |     ini entries:    [ssh_connection]  added in 2.7 of ansible.builtin    env:ANSIBLE_SSH_EXTRA_ARGS    added in 2.7 of ansible.builtin    var: ansible_ssh_extra_args    |    Extra exclusive to the 'ssh' CLI   |  |
