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.

  • 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.

  • 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

    • 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

Role documentation

undercloud-disabled-services

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_disabled_services

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.

  • hosts: undercloud

  • groups: pre-upgrade, pre-update

  • parameters:

  • roles: tls_everywhere

Role documentation

undercloud-proxy-validation

Verify proxy variables are properly set.

Check proxy configuration 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_proxy_validation

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

Role documentation

undercloud-sysctl

Verify undercloud sysctl option availability.

The undercloud will not install properly if some of the expected sysctl values are not available to be set.

  • hosts: undercloud

  • groups: prep, pre-upgrade, pre-update

  • parameters:

  • roles: undercloud_sysctl

Role documentation

validate-passwords-file

Check Undercloud passwords file.

Disallow updates if the passwords file is missing. If the undercloud was already deployed, the passwords file needs to be present so passwords that can’t be changed are persisted. If the file is missing it will break the undercloud, so we should fail-fast and let the user know about the problem. Both the old and new path to the file is checked. If either is found, the validation will pass as the old path will be migrated to the new during and update/upgrade.

  • hosts: undercloud

  • groups: prep, pre-upgrade, pre-update

  • parameters:

  • roles: validate_passwords_file
