vyos_command - Run one or more commands on VyOS devices¶
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.
Certain show commands in VyOS produce many lines of output and use a custom pager that can cause this module to hang. If the value of the environment variable ANSIBLE_VYOS_TERMINAL_LENGTH is not set, the default number of 10000 is used.
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.
interval
no
1
Configures the interval in seconds to wait between retries of the command. If the command does not pass the specified conditions, the interval indicates how long to wait before trying the command again.
match
no
all
any
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.
provider
no
A dict object containing connection details.
Dictionary object provider
parameter
required
default
choices
comments
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.
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.
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 the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
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.
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.
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.
