New in version 2.2.
The command module allows running one or more commands on remote devices running VyOS. This module can also be introspected to validate key parameters before returning successfully. If the conditional statements are not met in the wait period, the task fails.
parameter | required | default | choices | comments |
---|---|---|---|---|
commands | yes | The ordered set of commands to execute on the remote device running VyOS. The output from the command execution is returned to the playbook. If the wait_for argument is provided, the module is not returned until the condition is satisfied or the number of retries has been exceeded. |
||
host | yes | Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport. |
||
interval | no | 1 | Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditional, the interval indicates how to long to wait before trying the command again. |
|
match | no | all |
| The match argument is used in conjunction with the wait_for argument to specify the match policy. Valid values are all or any . If the value is set to all then all conditionals in the wait_for must be satisfied. If the value is set to any then only one of the values must be satisfied. |
password | no | Specifies the password to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead. |
||
port | no | 22 | Specifies the port to use when building the connection to the remote device. |
|
provider | no | Convenience method that allows all vyos arguments to be passed as a dict object. All constraints (required, choices, etc) must be met either by individual arguments or values in this dict. |
||
retries | no | 10 | Specifies the number of retries a command should be tried before it is considered failed. The command is run on the target device every retry and evaluated against the wait_for conditionals. |
|
ssh_keyfile | no | Specifies the SSH key to use to authenticate the connection to the remote device. This value is the path to the key used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead. |
||
timeout | no | 10 | Specifies idle timeout for the connection, in seconds. Useful if the console freezes before continuing. For example when saving configurations. |
|
username | no | Configures the username to use to authenticate the connection to the remote device. This value is used to authenticate the SSH session. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead. |
||
wait_for | no |
Specifies what to evaluate from the output of the command and what conditionals to apply. This argument will cause the task to wait for a particular conditional to be true before moving forward. If the conditional is not true by the configured retries, the task fails. See examples. aliases: waitfor

# Note: examples below use the following provider dict to handle # transport and authentication to the node. vars: cli: host: "{{ inventory_hostname }}" username: vyos password: vyos transport: cli - vyos_command: commands: - show interfaces ethernet {{ item }} provider: "{{ cli }}" with_items: - eth0 - eth1 - vyos_command: commands: - show version - show hardware cpu wait_for: - "result[0] contains 'VyOS 1.1.7'" provider: "{{ cli }}"
Common return values are documented here Common Return Values, the following are the fields unique to this module:
name | description | returned | type | sample |
---|---|---|---|---|
stdout_lines | The value of stdout split into a list | always | list | [['...', '...'], ['...'], ['...']] |
stdout | The set of responses from the commands | always | list | ['...', '...'] |
failed_conditions | The conditionals that failed | failed | list | ['...', '...'] |
warnings | The list of warnings (if any) generated by module based on arguments | always | list | ['...', '...'] |
