junipernetworks.junos.junos_command module – Run arbitrary commands on an Juniper JUNOS device

Note

This module is part of the junipernetworks.junos collection (version 3.1.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install junipernetworks.junos. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: junipernetworks.junos.junos_command.

New in junipernetworks.junos 1.0.0

Synopsis 

Sends an arbitrary set of commands to an JUNOS node and returns the results read from the device. This module includes an argument that will cause the module to wait for a specific condition before returning or timing out if the condition is not met.

Note

This module has a corresponding action plugin.

Requirements 

The below requirements are needed on the host that executes this module.

jxmlease
ncclient (>=v0.5.2)

Parameters 

Parameter	Comments
commands list / elements=string	The commands to send to the remote junos 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 been exceeded.
display aliases: format, output string	Encoding scheme to use when serializing output from the device. This handles how to properly understand the output and apply the conditionals path to the result set. For rpcs argument default display is `xml` and for commands argument default display is `text`. Value `set` is applicable only for fetching configuration from device. Choices: `"text"` `"json"` `"xml"` `"set"`
interval integer	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. Default: `1`
match string	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. Choices: `"any"` `"all"` ← (default)
provider dictionary	Deprecated Starting with Ansible 2.5 we recommend using `connection: network_cli` or `connection: netconf`. For more information please see the Junos OS Platform Options guide. A dict object containing connection details.
host string	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.
password string	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 integer	Specifies the port to use when building the connection to the remote device. The port value will default to the well known SSH port of 22 (for `transport=cli`) or port 830 (for `transport=netconf`) device.
ssh_keyfile path	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 integer	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.
transport string	Configures the transport connection to use when connecting to the remote device. Choices: `"cli"` `"netconf"` ← (default)
username string	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.
retries integer	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. Default: `10`
rpcs list / elements=string	The `rpcs` argument accepts a list of RPCs to be executed over a netconf session and the results from the RPC execution is return to the playbook via the modules results dictionary.
wait_for aliases: waitfor list / elements=string	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.

Notes 

Note

This module requires the netconf system service be enabled on the remote device being managed.
Tested against vSRX JUNOS version 15.1X49-D15.4, vqfx-10000 JUNOS Version 15.1X53-D60.4.
Recommended connection is netconf. See the Junos OS Platform Options.
This module also works with network_cli connections and with local connections for legacy playbooks.
For information on using CLI and netconf see the :ref:`Junos OS Platform Options guide <junos_platform_options>`
