ansible-role-tripleo-modify-image

There is a known issue when building container images with buildah. The default format for the image is OCI, but podman 1.6.x contains stricter restrictions about container format metadata. As a result, containers that you push to the undercloud registry can fail if they were originally in OCI format.

The workaround is to use the --format docker option to build images in docker format instead of OCI format, and you can push the containers to the undercloud registry successfully.

diskimage-builder

Previously, the nouveau kernel module was included in initramfs and conflicted with the nVidia vGPU drivers. As a result, the boot process could hang on RHOSP RHEL8 compute nodes with nVidia vGPU cards and drivers installed.

With this update, nouveau is explicitly omitted from the RHOSP initramfs.

openstack-tripleo-heat-templates

Previously, there was a change to the log parameter in the podman interface that introduced an issue with tripleo-heat-templates, which caused updates to fail.

With this update, the issue has been resolved and updates pass successfully.
The Compute services (nova) can fail to deploy because the nova_wait_for_compute_service script is unable to query the Nova API. If you use a remote container image registry outside of the undercloud, the Nova API service might not finish deploying in time.

The workaround is to rerun the deployment command, or to use a local container image registry on the undercloud.
Previously, changing the default membership role from Member to member caused ceph-rgw to deny access to standard users because keystone roles are case insensitive, but ceph-rgw role matching is case sensitive. As a result, users with the member role could not access ceph-rgw.

With this update, ceph-rgw accepts users with both Member and member roles.
Previously, deploying the stack with all networks disabled failed because the 'cloud_name_{{network.name_lower}}' property was defined for disabled networks.

With this update, the 'cloud_name_{{network.name_lower}}' property is no longer added for disabled networks and deployments are successful.
With this update, the credentials that you supply in the ContainerImageRegistryCredentials parameter pass to ceph-ansible automatically if the registry name matches the registry name in the ceph_namespace parameter.
In Red Hat OpenStack Platform (RHOSP) 15, the rhel-registration pre-deployment script has been removed because it is not compatible with RHEL8. Use the Ansible-based overcloud registration method instead:

openstack-tripleo-image-elements

Previously, the default NIC naming changed to use non-persistent node names such as ethXX instead of consistent names like enoX, ensXfY, ensX. As a result, the NIC names present in the introspection data did not match the overcloud NIC names.

With this update, the setting net.ifnames=0 has been removed from grub-config in the overcloud image and the introspection data contains consistent NIC names.

openstack-tripleo-validations

Previously, the default values for dhcp_start and dhcp_end in the undercloud.conf file did not provide enough IP addresses to pass tripleo validation and the ctlplane-ip-range validation failed.

With this update, the IP range is larger and validation passes successfully.

os-net-config

Previously, routes on SR-IOV PF interfaces were not set properly and these routes were ignored.

With this update, routes for SR-IOV PF interfaces function correctly.
