Using this Collection

Information about using collections can be found here:

https://docs.ansible.com/ansible/latest/user_guide/collections_using.html

The roles in this collection are in the redhatofficial.cloud_utils namespace.

They can be used by adding the collection to the playbook:

---
- hosts: all
  collections:
    - redhatofficial.cloud_utils

Roles

Roles provided by this project. Examples of how to use these roles are included in the top-level playbooks directory

enable_chrony

Enables chrony and disables ntp.

idm_register_ipa_client

Registers an IPA client with an IdM or IPA server.

Options

parameter	requried	default	comments
idm_server	yes		The IdM/IPA server to regsiter the IPA client with
idm_domain	yes		The IdM/IPA domain to register the IPA client with
idm_enroll_user	yes		The IdM/IPA user to enroll the IPA client with
idm_enroll_password	yes		The IdM/IPA password to enroll the IPA client with
idm_register_force	no	False	If `true` and IPA client is already registered it will be unregistered.

Notes

Does not configure NTP

configure_vm_network_and_ip

Configures the virtualization provider network and IP for given hosts. This is useful if need migrate a VM from one vlan/subnet to another vlan/subnet by updating both the virtualization provider and destination host.

The concept is that this playbook is cloud provider agnostic and can figure out how to move a VM from one network to another on any cloud provider, staying on that same provider, based on gathering facts about the VM. Though currently it has only been tested and written for a couple providers, as need arises for more providers the playbook can be easly extended to handle more.

Tested With

Red Hat Virtualization
- 4.0.5
VMware vCenter
- 5.1.0

Assumptions

Only handles one network interface
Assumes migrating the first network interface
target host facts are gathered so that ansible_virtualization_type is set
ansible_virtualization_type in ['RHEV', 'VMware']

Options

parameter	required	default	choices	comments
ansible_manage_etc_hosts	no	false	true, false, yes, no	Flag to control if /etc/hosts is updated with newly configured ip address
vm_network_ip4	yes			IP4 address to set for the VM
vm_network_ip4_netmask_prefix	yes			IP4 address netmask prefex to set for the VM
vm_network_gw4	yes			IP4 gateway to set for the VM
vm_network_dns4	no			List of IP4 DNS hosts to set for the VM
vm_network_ifname	no	`eth0` for `RHEV`, `ens192` for `VMware`		Ethernet interface name to set for the VM
vm_network_conn_name	no	System {{ vm_network_ifname }}		Ethernet connection name to set for the vm
virt_api_bastion	no	localhost		Bastion host to use to do API calls to the virtulization provider.
virt_api_insecure	no	False	True/False	Whether the connection to the virtualization provider API is insecure or not, aka using trusted certificates.
virt_network	yes		Valid networks on the virtualization provider	Virtualization provider network to set for the VM
ovirt_url	If oVirt/RHV			oVirt/RHV url for API calls
ovirt_username	If oVirt/RHV			oVirt/RHV username for API calls
ovirt_password	If oVirt/RHV			oVirt/RHV passwrod for API calls
vsphere_hostname	If vSphere			vSphere hostname for API calls
vsphere_username	If vSphere			vSphere username for API calls
vsphere_password	If vSphere			vSphere password for API calls
vsphere_datacenter	If vSphere			vSphere datacenter for API calls. NOTE: attempted to determine this dynamically but could not find a way.
vsphere_cluster	If vSphere			vSphere cluster for API calls. NOTE: attempted to determine this dynamically but could not find a way.

optimize_kernel_scheduler

What is the suggested I/O scheduler to improve disk performance when using Red Hat Enterprise Linux with virtualization?. The following playbook configures noop for the IO queue scheduler kernel parameter for RHEL VMs on VMware infrastructure per How to use the Noop IO Scheduler.

Notes

A backup of the grub configuration is made when changed.
This playbook does not perform the required reboot to enable this paramater.
