New Charm Features
|
||||
==================
|
||||
|
||||
With each new feature, there is a corresponding example bundle in the form of a
|
||||
test bundle, and/or a `OpenStack Charms Deployment Guide`_ section which
|
||||
details the use of the feature. For example test bundles, see the
|
||||
src/tests/bundles/ directory within the relevant charm repository.
|
||||
|
||||
Preview Charm Features
|
||||
======================
|
||||
|
||||
mysql-innodb-cluster and mysql-router
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The 20.02 OpenStack Charms release updates two tech preview charms to deploy
|
||||
MySQL 8 for OpenStack: mysql-innodb-cluster and mysql-router.
|
||||
|
||||
.. note :: These charms are in preview state and are not production-ready. The
|
||||
charms are ready for **testing** in OpenStack clouds.
|
||||
|
||||
.. note :: Both charms are only deployable on Ubuntu 19.10 and greater.
|
||||
|
||||
The mysql-innodb-cluster charm deploys MySQL 8 in an InnoDB cluster with a
|
||||
read/write node and N number of read-only nodes.
|
||||
|
||||
.. note :: The mysql-innodb-cluster charm is intended for deploying a cluster
|
||||
and therefore does not support single-unit or non-clustered
|
||||
deployments.
|
||||
|
||||
The mysql-router charm deploys MySQL 8 mysqlrouter which will proxy database
|
||||
requests from the principle charm application to a MySQL 8 InnoDB Cluster.
|
||||
MySQL Router handles cluster communication and understands the cluster schema.
|
||||
|
||||
.. note :: The mysql-router charm is deployed as a subordinate on the principle
|
||||
charm application.
|
||||
|
||||
A simple example deployment:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju deploy cs:keystone
|
||||
juju deploy cs:~openstack-charmers-next/mysql-router
|
||||
juju deploy -n 3 cs:~openstack-charmers-next/mysql-innodb-cluster
|
||||
juju add-relation mysql-router:db-router mysql-innodb-cluster:db-router
|
||||
|
||||
OVN
|
||||
~~~
|
||||
|
||||
The 20.04 OpenStack Charms release updates the tech preview suite of charms
|
||||
that allows you to model Open Virtual Network (OVN). OVN provides open source
|
||||
network virtualization for Open vSwitch (OVS).
|
||||
|
||||
One of the main drivers for this enablement work is the prospect of being able
|
||||
to hardware-offload everything. This is possible due to how OVN programs
|
||||
everything in Open vSwitch with OpenFlow rules. This in turn provides a
|
||||
uniform way of programming the hardware forwarding tables of supported NICs.
|
||||
|
||||
Hardware-offloading is a prerequisite for effective handling of workloads with
|
||||
high bandwidth consumption.
|
||||
|
||||
OVN also provides a more flexible way of configuring external Layer3 networking
|
||||
as OVN does not require every node (``Chassis`` in OVN terminology) in a
|
||||
deployment to have direct external connectivity. This plays nicely with
|
||||
Layer3-only datacenter fabrics (RFC 7938).
|
||||
|
||||
East/West traffic is distributed by default. North/South traffic is highly
|
||||
available by default. Liveness detection is done using the Bidirectional
|
||||
Forwarding Detection (BFD) protocol.
|
||||
|
||||
Please refer to appendix `Open Virtual Network (OVN)`_ in the `OpenStack Charms
|
||||
Deployment Guide`_ for more details.
|
||||
|
||||
Known feature gaps at this point in time:
|
||||
|
||||
* No validation has been done with DPDK, SR-IOV or hardware-offloading in the
|
||||
charms.
|
||||
|
||||
* Support for the Octavia OVN provider driver has not been implemented in the
|
||||
charms and no validation has been done with LBaaS in general.
|
||||
|
||||
* Only limited validation has been done with other Neutron extensions, and it
|
||||
may be possible to configure unsupported combinations of features with
|
||||
undefined results.
|
||||
|
||||
* There is an unresolved issue with security groups rules that reference
|
||||
remote security groups. Please remove any such rules while testing.
|
||||
|
||||
Example of how you could reset your default security group rules:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
PROJECT_ID=$(openstack project list -f value -c ID \
|
||||
--domain admin_domain)
|
||||
SECGRP_ID=$(openstack security group list --project $PROJECT_ID \
|
||||
| awk '/default/{print$2}')
|
||||
openstack security group rule delete \
|
||||
$(openstack security group rule list $SECGRP_ID| awk '/IPv./{print$2}')
|
||||
openstack security group rule create --egress --protocol any \
|
||||
--ethertype IPv4 $SECGRP_ID
|
||||
openstack security group rule create --egress --protocol any \
|
||||
--ethertype IPv6 $SECGRP_ID
|
||||
openstack security group rule create --ingress --protocol any \
|
||||
--ethertype IPv4 $SECGRP_ID --remote-ip YOUR_IPV4_LAB_NETWORK_CIDR
|
||||
openstack security group rule create --ingress --protocol any \
|
||||
--ethertype IPv6 $SECGRP_ID --remote-ip YOUR_IPV6_LAB_NETWORK_CIDR
|
||||
|
||||
Upgrading charms
|
||||
================
|
||||
|
||||
Always use the latest stable charm revision before proceeding with topological
|
||||
changes, charm application migrations, workload upgrades, series upgrades, or
|
||||
bug reports.
|
||||
|
||||
Please ensure that the ``keystone`` charm is upgraded first.
|
||||
|
||||
To upgrade an existing deployment to the latest charm version simply use the
|
||||
``upgrade-charm`` command. For example:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju upgrade-charm keystone
|
||||
|
||||
Charm upgrades and OpenStack upgrades are functionally different. Charm
|
||||
upgrades ensure that the deployment has the latest charm revision, containing
|
||||
the latest charm fixes and charm features available for that deployment,
|
||||
whereas OpenStack upgrades influence the software package versions of OpenStack
|
||||
itself.
|
||||
|
||||
Charm upgrades do not trigger OpenStack upgrades. However, OpenStack upgrades
|
||||
do require the latest charm version as pre-requisite.

Known Issues
|
||||
============
|
||||
|
||||
Masakari and Masakari Monitors
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Both Masakari charms remain as previews. Bugs `LP #1728527`_ and `LP #1839715`_
|
||||
need to be resolved in order to arrive at a successful instance HA deployment.
|
||||
Bug `LP #1773765`_ is likely to affect on-going support of a Masakari
|
||||
deployment.
|
||||
|
||||
Glance Simplestreams Sync
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
When deploying the ``glance-simplestreams-sync`` charm on Bionic a more recent
|
||||
version of the simplestreams package must be installed by configuring a PPA:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju config glance-simplestreams-sync source=ppa:simplestreams-dev/trunk
|
||||
|
||||
See bug `LP #1790904`_ for details.
|
||||
|
||||
Designate and Vault at Ocata and earlier
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The ``designate`` charm for OpenStack releases Pike and earlier does not yet
|
||||
support SSL via Vault and the certificates relation. See bug `LP #1839019
|
||||
<https://bugs.launchpad.net/charm-designate/+bug/1839019>`__
|
||||
|
||||
Current versions of OpenStack with Vault and the certificates relation are
|
||||
supported by the Designate charm.
|
||||
|
||||
Restart Nova services after adding certificates relation
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
A race condition exists with the use of the 'certificates' relation.
|
||||
When SSL certificates are issued Nova services may attempt to talk
|
||||
to the placement API over HTTP while the API has already changed to
|
||||
HTTPS. See bug `LP #1826382 <https://bugs.launchpad.net/nova/+bug/1826382>`__.
|
||||
|
||||
To mitigate against this, restart nova-compute and nova-scheduler
|
||||
services once certificates have been issued:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju run --application nova-compute "systemctl restart nova-compute"
|
||||
juju run --application nova-cloud-controller "systemctl restart nova-scheduler"
|
||||
|
||||
