ansible.builtin.ssh - connect via ssh client binary
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-agent is highly recommended.
Parameters
Parameter Choices/Defaults Configuration Comments string
ini entries:
[ssh_connection]
control_path = Noneenv: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.
string
Default:
"~/.ansible/cp"
ini entries:
[ssh_connection]
control_path_dir = ~/.ansible/cpenv: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.
string
Default:
"inventory_hostname"
var: ansible_host
var: ansible_ssh_host
Hostname/ip to connect to.
boolean
- no
- yes
ini entries:
[defaults]
host_key_checking = None[ssh_connection]
host_key_checking = Noneadded 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
string
var: ansible_password
var: ansible_ssh_pass
var: ansible_ssh_password
Authentication password for the remote_user. Can be supplied as CLI option.
boolean
Default:
- no
- yes
"ANSIBLE_PIPELINING"
ini entries:
[defaults]
pipelining = ANSIBLE_PIPELINING[ssh_connection]
pipelining = ANSIBLE_PIPELININGenv: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.
integer
Default:
22
ini entries:
[defaults]
remote_port = 22env:ANSIBLE_REMOTE_PORT
var: ansible_port
var: ansible_ssh_port
Remote port to connect to.
string
ini entries:
[defaults]

var: ansible_private_key_file
var: ansible_ssh_private_key_file
Path to private key file to use for authentication
string
ini entries:
[defaults]
remote_user = Noneenv: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
integer
Default:
3
ini entries:
[connection]
retries = 3[ssh_connection]
retries = 3env:ANSIBLE_SSH_RETRIES
var: ansible_ssh_retries
added in 2.7 of ansible.builtin
Number of attempts to connect.
string
Default:
"scp"
ini entries:
[ssh_connection]
scp_executable = scpenv: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.
string
ini entries:

string
Default:
"smart"
ini entries:
[ssh_connection]
scp_if_ssh = smartenv:ANSIBLE_SCP_IF_SSH
var: ansible_scp_if_ssh
added in 2.7 of ansible.builtin
Preferred method to use when transfering files over ssh
When set to smart, Ansible will try them until one succeeds or they all fail
If set to True, it will force 'scp', if False it will use 'sftp'
boolean

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.
