ssh – connect via ssh client binary¶
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 |
---|---|---|---|
control_path
-
|
ini entries:
[ssh_connection] env:ANSIBLE_SSH_CONTROL_PATH
var: ansible_control_path
|
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
-
|
Default: "~/.ansible/cp"
|
ini entries:
[ssh_connection] env:ANSIBLE_SSH_CONTROL_PATH_DIR
var: ansible_control_path_dir
|
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
-
|
Default: "inventory_hostname"
|
var: ansible_host
var: ansible_ssh_host
|
Hostname/ip to connect to.
|
host_key_checking
boolean
|
ini entries:
[defaults] [ssh_connection] env:ANSIBLE_HOST_KEY_CHECKING
env:ANSIBLE_SSH_HOST_KEY_CHECKING
var: ansible_host_key_checking
var: ansible_ssh_host_key_checking
|
Determines if ssh should check host keys
|
|
password
-
|
var: ansible_password
var: ansible_ssh_pass
|
Authentication password for the
remote_user . Can be supplied as CLI option. |
|
pipelining
boolean
|
Default: "ANSIBLE_PIPELINING"
|
ini entries:
[defaults] env:ANSIBLE_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
-
|
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
-
|
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
|
Number of attempts to connect.
|
scp_executable
-
added in 2.6 |
Default: "scp"
|
ini entries:
[ssh_connection] env:ANSIBLE_SCP_EXECUTABLE
var: ansible_scp_executable
|
This defines the location of the scp binary. It defaults to `scp` which will use the first binary available in $PATH.
|
scp_extra_args
-
|
ini entries:
[ssh_connection] env:ANSIBLE_SCP_EXTRA_ARGS
var: ansible_scp_extra_args
|
Extra exclusive to the ``scp`` CLI
|
|
scp_if_ssh
-
|
Default: "smart"
|
ini entries:
[ssh_connection] env:ANSIBLE_SCP_IF_SSH
var: ansible_scp_if_ssh
|
Prefered 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'
|
sftp_batch_mode
boolean
|
|
ini entries:
[ssh_connection] env:ANSIBLE_SFTP_BATCH_MODE
var: ansible_sftp_batch_mode
|
TODO: write it
|
sftp_executable
-
added in 2.6 |
Default: "sftp"
|
ini entries:
[ssh_connection] env:ANSIBLE_SFTP_EXECUTABLE
var: ansible_sftp_executable
|
This defines the location of the sftp binary. It defaults to ``sftp`` which will use the first binary available in $PATH.
|
sftp_extra_args
-
|
ini entries:
[ssh_connection] env:ANSIBLE_SFTP_EXTRA_ARGS
var: ansible_sftp_extra_args
|
Extra exclusive to the ``sftp`` CLI
|
|
ssh_args
-
|
Default: "-C -o ControlMaster=auto -o ControlPersist=60s"
|
ini entries:
[ssh_connection] env:ANSIBLE_SSH_ARGS
var: ansible_ssh_args
|
Arguments to pass to all ssh cli tools
|
ssh_common_args
-
|
ini entries:
[ssh_connection] env:ANSIBLE_SSH_COMMON_ARGS
var: ansible_ssh_common_args
|
Common extra args for all ssh CLI tools
|
|
ssh_executable
-
added in 2.2 |
Default: "ssh"
|
ini entries:
[ssh_connection] env:ANSIBLE_SSH_EXECUTABLE
var: ansible_ssh_executable
|
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
-
|
ini entries:
[ssh_connection] env:ANSIBLE_SSH_EXTRA_ARGS
var: ansible_ssh_extra_args
