bigip_vcmp_guest – Manages vCMP guests on a BIG-IP

New in version 2.5.


Synopsis

  • Manages vCMP guests on a BIG-IP. This functionality only exists on actual hardware and must be enabled by provisioning vcmp with the bigip_provision module.

Requirements

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

  • f5-sdk >= 3.0.16

Parameters

Parameter Choices/Defaults Comments

allowed_slots

-

added in 2.7

Contains those slots that the guest is allowed to be assigned to.

When the host determines which slots this guest should be assigned to, only slots in this list will be considered.

This is a good way to force guests to be assigned only to particular slots, or, by configuring disjoint allowed_slots on two guests, that those guests are never assigned to the same slot.

By default this list includes every available slot in the cluster. This means, by default, the guest may be assigned to any slot.

cores_per_slot

-

Specifies the number of cores that the system allocates to the guest.

Each core represents a portion of CPU and memory. Therefore, the amount of memory allocated per core is directly tied to the amount of CPU. This amount of memory varies per hardware platform type.

The number you can specify depends on the type of hardware you have.

In the event of a reboot, the system persists the guest to the same slot on which it ran prior to the reboot.

delete_virtual_disk

boolean

  • no

  • yes

When state is absent, will additionally delete the virtual disk associated with the vCMP guest. By default, this value is no.

initial_image

-

Specifies the base software release ISO image file for installing the TMOS hypervisor instance and any licensed BIG-IP modules onto the guest's virtual disk. When creating a new guest, this parameter is required.

mgmt_address

-

Specifies the IP address, and subnet or subnet mask that you use to access the guest when you want to manage a module running within the guest. This parameter is required if the mgmt_network parameter is bridged.

When creating a new guest, if you do not specify a network or network mask, a default of /24 (255.255.255.0) will be assumed.

mgmt_network

-

  • bridged
  • isolated
  • host only

Specifies the method by which the management address is used in the vCMP guest.

When bridged, specifies that the guest can communicate with the vCMP host's management network.

When isolated, specifies that the guest is isolated from the vCMP host's management network. In this case, the only way that a guest can communicate with the vCMP host is through the console port or through a self IP address on the guest that allows traffic through port 22.

When host only, prevents the guest from installing images and hotfixes other than those provided by the hypervisor.

If the guest setting is isolated or host only, the mgmt_address does not apply.

Concerning mode changing, changing bridged to isolated causes the vCMP host to remove all of the guest's management interfaces from its bridged management network. This immediately disconnects the guest's VMs from the physical management network. Changing isolated to bridged causes the vCMP host to dynamically add the guest's management interfaces to the bridged management network. This immediately connects all of the guest's VMs to the physical management network. Changing this property while the guest is in the configured or provisioned state has no immediate effect.

mgmt_route

-

Specifies the gateway address for the mgmt_address.

If this value is not specified when creating a new guest, it is set to none.

The value none can be used during an update to remove this value.

min_number_of_slots

-

added in 2.7

Specifies the minimum number of slots that the guest must be assigned to in order to deploy.

This field dictates the number of slots that the guest must be assigned to.

If at the end of any allocation attempt the guest is not assigned to at least this many slots, the attempt fails and the change that initiated it is reverted.

A guest's min_number_of_slots value cannot be greater than its number_of_slots.

name

- / required

The name of the vCMP guest to manage.

number_of_slots

-

added in 2.7

Specifies the number of slots for the system to use for creating the guest.

This value dictates how many cores a guest is allocated from each slot that it is assigned to.

Possible values are dependent on the type of blades being used in this cluster.

The default value depends on the type of blades being used in this cluster.

partition

-

Default:

"Common"

Device partition to manage resources on.

password

- / required

The password for the user account used to connect to the BIG-IP.

You may omit this option by setting the environment variable F5_PASSWORD.


aliases: pass, pwd

provider

-

added in 2.5

Default:

null

A dict object containing connection details.

password

- / required

The password for the user account used to connect to the BIG-IP.

You may omit this option by setting the environment variable F5_PASSWORD.


aliases: pass, pwd

server

- / required

The BIG-IP host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

-

Default:

443

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

ssh_keyfile

-

Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports.

You may omit this option by setting the environment variable ANSIBLE_NET_SSH_KEYFILE.

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.

transport

- / required

  • rest
  • cli

Configures the transport connection to use when connecting to the remote device.

user

- / required

The username to connect to the BIG-IP with. This user must have administrative privileges on the device.

You may omit this option by setting the environment variable F5_USER.

validate_certs

boolean

  • no
  • yes

If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.

You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

server

- / required

The BIG-IP host.

You may omit this option by setting the environment variable F5_SERVER.

server_port

-

added in 2.2

Default:

443

The BIG-IP server port.

You may omit this option by setting the environment variable F5_SERVER_PORT.

state

-

  • configured
  • disabled
  • provisioned
  • present

  • absent

The state of the vCMP guest on the system. Each state implies the actions of all states before it.

When configured, guarantees that the vCMP guest exists with the provided attributes. Additionally, ensures that the vCMP guest is turned off.

When disabled, behaves the same as configured the name of this state is just a convenience for the user that is more understandable.

When provisioned, will ensure that the guest is created and installed. This state will not start the guest; use deployed for that. This state is one step beyond present as present will not install the guest; only setup the configuration for it to be installed.

When present, ensures the guest is properly provisioned and starts the guest so that it is in a running state.

When absent, removes the vCMP from the system.

user

- / required

The username to connect to the BIG-IP with. This user must have administrative privileges on the device.

You may omit this option by setting the environment variable F5_USER.

validate_certs

boolean

added in 2.0

  • no
  • yes

If no, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates.

You may omit this option by setting the environment variable F5_VALIDATE_CERTS.

vlans

-

VLANs that the guest uses to communicate with other guests, the host, and with the external network. The available VLANs in the list are those that are currently configured on the vCMP host.

The order of these VLANs is not important; in fact, it's ignored. This module will order the VLANs for you automatically. Therefore, if you deliberately re-order them in subsequent tasks, you will find that this module will not register a change.



Notes

Note

  • This module can take a lot of time to deploy vCMP guests. This is an intrinsic limitation of the vCMP system because it is booting real VMs on the BIG-IP device. This boot time is very similar in length to the time it takes to boot VMs on any other virtualization platform; public or private.
  • When BIG-IP starts, the VMs are booted sequentially; not in parallel. This means that it is not unusual for a vCMP host with many guests to take a long time (60+ minutes) to reboot and bring all the guests online. The BIG-IP chassis will be available before all vCMP guests are online.
  • For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
  • Requires the f5-sdk Python package on the host. This is as easy as pip install f5-sdk.
  • Requires BIG-IP software version >= 12.
  • The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
