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 | Default: 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 |
| 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 |
| 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 | Default: None | 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 |
| 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 | Default: 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 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 | Default: None | 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 | Default: None | 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"
Return Values
Common return values are documented here, the following are the fields unique to this module:
Key | Returned | Description |
---|---|---|
failed_conditions list | failed | the conditionals that failed Sample: ['...', '...'] |
stdout list | always | the set of responses from the commands Sample: ['...', '...'] |
stdout_lines list | always | The value of stdout split into a list Sample: [['...', '...'], ['...'], ['...']] |
Status
This module is flagged as preview which means that it is not guaranteed to have a backwards compatible interface.
