Pike Series (3.x.y) Release Notes

Kayobe 3.1.0

Kayobe 3.1.0 was released on 22nd February 2018 and is based on the Pike release of OpenStack.

Features

  • Adds --interface-limit and --interface-description-limit arguments to the kayobe physical network configure command. These arguments allow configuration to be limited to a subset of switch interfaces.

  • Adds a --display argument to kayobe physical network configure command. This will output the candidate switch configuration without applying it.

  • Adds support for configuration of custom fluentd filters, and additional config file templates for heat, ironic, keystone, magnum, murano, sahara, and swift in $KAYOBE_CONFIG_PATH/kolla/config/<component>/.

  • Adds support for specifying a local Yum mirror for package installation.

  • Adds the command kayobe network connectivity check which can be used to verify network connectivity in the cloud hosts.

  • Adds a variable kolla_nova_compute_ironic_host which may be used to set which hosts run the nova compute service for ironic. This may be used to avoid the experimental HA nova compute service for ironic, by specifying a single host.

  • Adds support for deployment of virtualised compute hosts. These hosts should be added to the [compute] group.

  • Adds support for multiple external networks. external_net_names should be a list of names of networks.

  • Adds commands for management of baremetal compute nodes - kayobe baremetal compute inspect, kayobe baremetal compute manage, and kayobe baremetal compute provide.

  • Adds support for installation and use of a python virtual environment for remote execution of ansible modules, providing isolation from the system’s python packages. This is enabled by setting a host variable, ansible_python_interpreter, to the path to a python interpreter in a virtualenv, noting that Jinja2 templating is not supported for this variable.

  • Adds support for configuration of a python virtual environment for remote execution of ansible modules in kolla-ansible, providing isolation from the system’s python packages. This is enabled by setting the variable kolla_ansible_target_venv to a path to the virtualenv. The default for this variable is {{ virtualenv_path }}/kolla-ansible.

  • Adds tags to plays to support more fine grained configuration using the --tags argument.

  • Adds support for deployment of storage hosts. These hosts should be added to the [storage] group.

  • Adds support for the tagging of ceph disks.

  • Adds support for post-deployment configuration of Grafana data sources and dashboards.

Upgrade Notes

  • Modifies the default value for inspector_manage_firewall from False to True. Management of the firewall by ironic inspector is important to ensure that DHCP offers are not made to nodes during provisioning by inspector’s DHCP server.

  • Disables swift by default. The default value of kolla_enable_swift is now no.

  • The default list of neutron ML2 mechanism drivers (kolla_neutron_ml2_mechanism_drivers) has been removed in favour of using the defaults provided by kolla-ansible. Users relying on the default list of openvswitch and genericswitch should set the value explicitly.

  • Adds a variable config_path, used to set the base path to configuration on remote hosts. The default value is /opt/kayobe/etc.

  • Modifies the variable used to configure the kolla build configuration path from kolla_config_path to kolla_build_config_path. This provides a cleaner separation of kolla and kolla-ansible configuration options. The default value is {{ config_path }}/kolla.

  • Adds a group container-image-builders, which defaults to containing the seed. Hosts in this group will build container images. Previously, container images for the seed were built on the seed, and container images for the overcloud were built on the controllers. The new design is intended to encourage a build, push, pull workflow.

  • It is now possible to configure kayobe to use a virtual environment for remote execution of ansible modules. If this is required, the following commands should be run in order to ensure that the virtual environments exist on the remote hosts:

    (kayobe) $ kayobe seed hypervisor host upgrade
(kayobe) $ kayobe seed host upgrade
(kayobe) $ kayobe overcloud host upgrade

  • The default behaviour is now to configure kolla-ansible to use a virtual environment for remote execution of ansible modules. In order to ensure the virtual environment exists on the remote hosts, run the following commands:

    (kayobe) $ kayobe seed hypervisor host upgrade
(kayobe) $ kayobe seed host upgrade
(kayobe) $ kayobe overcloud host upgrade

    The previous behaviour of installing python dependencies directly to the host can be used by setting kolla_ansible_target_venv to None.

  • Adds a workaround for an issue with CentOS cloud images 7.2 (1511) onwards, which have a bogus name server entry in /etc/resolv.conf, 10.0.2.3. Cloud-init only appends name server entries to this file, and will not remove this bogus entry. Typically this leads to a delay of around 30 seconds when connecting via SSH, due to a timeout in NSS. The workaround employed here is to remove this bogus entry from the image using virt-customize, if it exists. See https://bugs.centos.org/view.php?id=14369.

  • Adds a group storage, which used for deploy node with cinder-volume, LVM or ceph-osd. If you want to add these services to compute or control group, you need to override kolla_overcloud_inventory_storage_groups.

Kayobe 3.0.0

Kayobe 3.0.0 was released on 20th September 2017.

Features

  • Adds support for the OpenStack Pike release.

  • Adds support for saving overcloud service configuration to the Ansible control host.

  • Adds support for generating overcloud service configuration, without applying it to the running system.
