pre-update¶
check-for-dangling-images¶
Check for podman dangling images.
Make sure before update we do not have any dangling images.

- groups: pre-update 
- parameters: - check_for_dangling_images_debug: False 
 
- roles: check_for_dangling_images 
Role documentation
compute-tsx¶
RHEL8.x kernel flag for Compute nodes validation.
RHEL-8.3 kernel disabled the Intel TSX (Transactional Synchronization Extensions) feature by default as a preemptive security measure, but it breaks live migration from RHEL-7.9 (or even RHEL-8.1 or RHEL-8.2) to RHEL-8.3.
Operators are expected to explicitly define the TSX flag in their KernelArgs for the compute role to prevent live-migration issues during the upgrade process.
This also impacts upstream CentOS systems.
- hosts: nova_libvirt 
- groups: pre-upgrade, pre-system-upgrade, pre-overcloud-prepare, pre-overcloud-upgrade, pre-overcloud-converge, pre-update, pre-update-prepare, pre-update-run, pre-update-converge 
- parameters: - compute_tsx_debug: False 
- compute_tsx_warning: False 
 
- roles: compute_tsx 
Role documentation
container-status¶
Ensure container status.
Detect failed containers and raise an error.
- hosts: undercloud, allovercloud 
- groups: backup-and-restore, pre-upgrade, pre-update, post-deployment, post-upgrade 
- parameters: 
- roles: container_status 
Role documentation
openstack-endpoints¶
Check connectivity to various OpenStack services.
This validation gets the PublicVip address from the deployment and tries to access Horizon and get a Keystone token.
- hosts: undercloud 
- groups: post-deployment, pre-upgrade, post-upgrade, pre-update, post-update 
- parameters: 
- roles: openstack_endpoints 
Role documentation
package-version¶
package-version.
Ensures we can access the wanted package version. Especially useful when you are switching repositories, for instance during an upgrade.
- hosts: all 
- groups: prep, pre-deployment, pre-upgrade, pre-update, pre-system-upgrade, pre-undercloud-upgrade, pre-overcloud-prepare, pre-overcloud-upgrade, pre-overcloud-converge, pre-ceph 
- parameters: - package_version_debug: False 
 
- roles: package_version 
Role documentation
repos¶
Check correctness of current repositories.
Detect whether the repositories listed in yum repolist can be connected to and that there is at least one repo configured.
Detect if there are any unwanted repositories (such as EPEL) enabled.
- hosts: undercloud, allovercloud 
- groups: pre-upgrade, pre-update 
- parameters: 
- roles: repos 
Role documentation
system-encoding¶
System encoding.
Ensure the local is unicode
- hosts: all 
- groups: pre-deployment, pre-upgrade, pre-update 
- parameters: - system_encoding_debug: False 
 
- roles: system_encoding 
Role documentation
undercloud-heat-purge-deleted¶
Verify heat-manage purge_deleted is enabled in crontab.
Without a purge_deleted crontab enabled, the heat database can grow very large. This validation checks that the purge_deleted crontab has been set up.
- hosts: undercloud 
- groups: pre-upgrade, pre-update, pre-deployment 
- parameters: - cron_check: heat-manage purge_deleted 
 
- roles: undercloud_heat_purge_deleted 
Role documentation
undercloud-ipa-server-check¶
Verify that the IPA server has the right permissions and ACI.
This validation is relevant for systems where TLS Everywhere is enabled.
A new ACI is needed on the FreeIPA server to ensure that certificates with IP SANs can be issued. This ACI will be delivered by default from FreeIPA 4.8.5.
In addition, a new permission is needed to add DNS zones for tripleo-ipa. This permission is an addition to the current permissions for the Nova Host Manager role.
This validation confirms that the new permission and ACI are present.

- groups: pre-upgrade, pre-update

Role documentation
undercloud-service-status¶
Verify undercloud services state before running update or upgrade.
Check undercloud status before running a stack update - especially minor update and major upgrade.
- hosts: undercloud 
- groups: backup-and-restore, post-upgrade, pre-upgrade, post-update, pre-update 
- parameters: 
- roles: undercloud_service_status
