enos_command - Run arbitrary commands on Lenovo ENOS devices

New in version 2.5.

Synopsis

  • Sends arbitrary commands to an ENOS node and returns the results read from the device. The enos_command 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.

Parameters

Parameter Choices/Defaults Comments
auth_pass
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
bool
    Choices:
  • no ←
  • yes
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
required
List of commands to send to the remote 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 retires as 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
    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
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.
authorize
bool
    Choices:
  • no ←
  • yes
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
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.
auth_pass
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
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.
timeout Default:
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
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 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 by 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
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.

Examples

# Note: examples below use the following provider dict to handle
#       transport and authentication to the node.
---
vars:
  cli:
    host: "{{ inventory_hostname }}"
    port: 22
    username: admin
    password: admin
    timeout: 30

---
- name: test contains operator
  enos_command:
    commands:
      - show version
      - show system memory
    wait_for:
      - "result[0] contains 'Lenovo'"
      - "result[1] contains 'MemFree'"
    provider: "{{ cli }}"
  register: result

- assert:
    that:
      - "result.changed == false"
      - "result.stdout is defined"

- name: get output for single command
  enos_command:
    commands: ['show version']
    provider: "{{ cli }}"
  register: result

- assert:
    that:
      - "result.changed == false"
      - "result.stdout is defined"

- name: get output for multiple commands
  enos_command:
    commands:
      - show version
      - show interface information
    provider: "{{ cli }}"
  register: result

- assert:
    that:
      - "result.changed == false"
      - "result.stdout is defined"
      - "result.stdout | length == 2"
