New in version 2.2.

Synopsis

Parameters

Parameter Choices/Defaults Comments
commands
required
List of commands to send to the remote dellos9 device over the configured provider. The resulting output from the command is returned. If the wait_for argument is provided, the module is not returned until the condition is satisfied or the number of retries has expired.
interval Default:
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
(added in 2.5)
    Choices:
  • 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
A dict object containing connection details.
username
User to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead.
host
required
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
Path to an ssh key used to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
timeout Default:
10
Specifies idle timeout (in seconds) for the connection. Useful if the console freezes before continuing. For example when saving configurations.
password
Password to authenticate the SSH session to the remote device. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
port Default:
22
Specifies the port to use when building the connection to the remote device.
retries Default:
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 conditions.
wait_for
(added in 2.2)
List of conditions to evaluate against the output of the command. The task will wait for each condition to be true before moving forward. If the conditional is not true within the configured number of retries, the task fails. See examples.
