nxos_install_os - Set boot options like boot, kickstart image and issu.

New in version 2.2.

Synopsis

  • Install an operating system by setting the boot options like boot image and kickstart image and optionally select to install using ISSU (In Server Software Upgrade).

Parameters

Parameter Choices/Defaults Comments
issu
(added in 2.5)
    Choices:
  • required
  • desired
  • yes
  • no ←
Upgrade using In Service Software Upgrade (ISSU). (Only supported on N9k platforms)
Selecting 'required' or 'yes' means that upgrades will only proceed if the switch is capable of ISSU.
Selecting 'desired' means that upgrades will use ISSU if possible but will fall back to disruptive upgrade if needed.
Selecting 'no' means do not use ISSU. Forced disruptive.
kickstart_image_file Default:
None
Name of the kickstart image file on flash. (Not required on all Nexus platforms)
provider Default:
None
Deprecated
Starting with Ansible 2.5 we recommend using connection: network_cli.
This option is only required if you are using NX-API.
For more information please see the NXOS Platform Options guide.

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 either the CLI login or the nxapi 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
(added in 2.5.3)
    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 argument is only used for the cli transport. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_SSH_KEYFILE will be used instead.
use_proxy
(added in 2.5)
    Choices:
  • yes ←
  • no
If no, the environment variables http_proxy and https_proxy will be ignored.
auth_pass
(added in 2.5.3)
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
(added in 2.3)
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. NX-API can be slow to return on long-running commands (sh mac, sh bgp, etc).
use_ssl
    Choices:
  • yes
  • no ←
Configures the transport to use SSL if set to true only when the transport=nxapi, otherwise this value is ignored.
password Default:
None
Specifies the password to use to authenticate the connection to the remote device. This is a common argument used for either cli or nxapi transports. If the value is not specified in the task, the value of environment variable ANSIBLE_NET_PASSWORD will be used instead.
validate_certs
    Choices:
  • yes
  • no
Default:
None
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 nxapi, this value is ignored.
port Default:
0 (use common port)
Specifies the port to use when building the connection to the remote device. This value applies to either cli or nxapi. 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
required
Default:
cli
Configures the transport connection to use when connecting to the remote device. The transport argument supports connectivity to the device over cli (ssh) or nxapi.
system_image_file
required
Name of the system (or combined) image file on flash.

Notes

Note

  • Tested against the following platforms and images - N9k 7.0(3)I4(6), 7.0(3)I5(3), 7.0(3)I6(1), 7.0(3)I7(1), 7.0(3)F2(2), 7.0(3)F3(2) - N3k 6.0(2)A8(6), 6.0(2)A8(8), 7.0(3)I6(1), 7.0(3)I7(1) - N7k 7.3(0)D1(1), 8.0(1), 8.2(1)
  • This module executes longer then the default ansible timeout value and will generate errors unless the module timeout parameter is set to a value of 500 seconds or higher. The example time is sufficent for most upgrades but this can be tuned higher based on specific upgrade time requirements. The module will exit with a failure message if the timer is not set to 500 seconds or higher.
  • Do not include full file paths, just the name of the file(s) stored on the top level flash directory.
  • This module attempts to install the software immediately, which may trigger a reboot.
  • In check mode, the module will indicate if an upgrade is needed and whether or not the upgrade is disruptive or non-disruptive(ISSU).
