eos_command - Run arbitrary commands on an Arista EOS device

New in version 2.1.

Synopsis

  • Sends an arbitrary set of commands to an EOS 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.

Options

parameter required default choices comments
auth_pass
 no none
Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTH_PASS will be used instead.
authorize
 no
  • yes
  • no
Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTHORIZE will be used instead.
commands
 yes
The commands to send to the remote EOS 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.
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
(added in 2.2)
 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 either the CLI login or the eAPI authentication depending on which transport is used. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_USERNAME will be used instead.
authorize
 no
  • yes
  • no
Instructs the module to enter privileged mode on the remote device before sending any commands. If not specified, the device will attempt to execute all commands in non-privileged mode. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTHORIZE will be used instead.
ssh_keyfile
 no
Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
auth_pass
 no none
Specifies the password to use if required to enter privileged mode on the remote device. If authorize is false, then this argument does nothing. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_AUTH_PASS 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.
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.
use_ssl
 no True
  • yes
  • no
Configures the transport to use SSL if set to true only when the transport=eapi. If the transport argument is not eapi, this value is ignored.
password
 no
Specifies the password to use to authenticate the connection to the remote device. This is a common argument used for either cli or eapi transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
validate_certs
 no
  • yes
  • no
If no, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates. If the transport argument is not eapi, this value is ignored.
port
 no 0 (use common port)
Specifies the port to use when building the connection to the remote device. This value applies to either cli or eapi. The port value will default to the appropriate transport common port if none is provided in the task. (cli=22, http=80, https=443).
transport
 yes cli
  • eapi
  • cli
Configures the transport connection to use when connecting 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
(added in 2.2)
 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

Return Values

Common return values are documented here Return Values, the following are the fields unique to this module:

name description returned type sample
failed_conditions
The list of conditionals that have failed
 failed list ['...', '...']
stdout
The set of responses from the commands
 always apart from low level errors (such as action plugin) list ['...', '...']
stdout_lines
The value of stdout split into a list
 always apart from low level errors (such as action plugin) list [['...', '...'], ['...'], ['...']]

Notes

Note

  • Tested against EOS 4.15

Status
