New Features¶

• Split off Ceph related container images

  This change releases an update on the default tripleo_containers jinjatemplate, splitting off the Ceph related container images.With this new approach pulling the ceph containers is optional, and canbe avoided by setting theceph_images boolean to False.e.g., passing something like the following:

  parameter_defaults:ContainerImagePrepare:-push_destination:trueset:name_prefix:openstack-name_suffix:''namespace:quay.io/tripleomasterneutron_driver:ovnrhel_containers:falsetag:current-tripleoceph_images:falseContainerImagePrepareDebug:trueContainerImageRegistryCredentials:{}

  avoid the ceph containers being pulled in the undercloud.To make this possible, a new jinja template processing approachhas been introduced, and a template basedir parameter (requiredby the jinja loader) has been added to the BaseImageManager.

Bug Fixes¶

• Fix high water mark memory usage on Cinder Volume and Backup services andreduce peak memory usage.

• Removes the use of the kernel parameternomodeset as it has beendiscovered it can cause blocking memory updates impacting latencysensitive applications and workloads.

Other Notes¶

• console=tty0 has been removed from the kernel arguments for overcloudnodes, this means that kernel boot messages will no longer be logged to thegraphics display. They are still logged to the serial console ttyS0. Thischange is required to avoid performance degradation caused by some graphicsdevices.

New Features¶

• The scriptstripleo-mount-image andtripleo-unmount-image will mountthe contents of an overcloud image file using qemu-nbd, making it availablefor chroot, or other read/write image operations. The scripts handlepartition image (overcloud-full.qcow2) as well as the whole-disk image(overcloud-hardened-uefi-full.qcow2) with its multiple LVM volume mountpoints.

Deprecation Notes¶

• The DeployArtifactURL(s) server is no longer makes any use of Swift when using built-in scripts to upload artifacts. The oldupload-swift-artifacts file is now a symlink pointed to the updatedupload-artifacts script. While the file has changed, the API remains the same. The symlink will ensure that legacy automation remains functional while moving over to the new script. The symlink will be removed in a future release.

Other Notes¶

• Removed skopeo based container image uploader. This has been deprecatedsince stein and does not work with our current registry implementation.

Bug Fixes¶

• The qemu user on the host gets created using uid/gid 107. Certificateson the host, but also the vhost-user sockets created by ovs use thisuid/gid. With the move to TCIB images the default kolla ids werereverted and the previous overwrite dropped. This make e.g. the qemuprocesses to fail to use the libvirt-vnc bind mounted certificates.This change brings back the previous overwrite of the qemu useruid/gid.
