Deploying with Heat Templates
|
|
=============================
|
|
|
|
It is possible to use the ``--templates`` and ``--environment-file``
|
|
options to override specific templates or even deploy using a separate
|
|
set of templates entirely.
|
|
|
|
|
|
Deploying an Overcloud using the default templates
|
|
--------------------------------------------------
|
|
|
|
The ``--templates`` option without an argument enables deploying using
|
|
the packaged Heat templates::
|
|
|
|
openstack overcloud deploy --templates
|
|
|
|
.. note::
|
|
|
|
The default location for the templates is
|
|
`/usr/share/openstack-tripleo-heat-templates`.
|
|
|
|
|
|
Overriding specific templates with local versions
|
|
-------------------------------------------------
|
|
|
|
You may use heat environment files (via the ``--environment-file`` or ``-e``
|
|
option), combined with the ``--templates`` option to override specific
|
|
templates, e.g to test a bugfix outside of the location of the packaged
|
|
templates.
|
|
|
|
The mapping between heat resource types and the underlying templates can be
|
|
found in
|
|
`/usr/share/\
|
|
openstack-tripleo-heat-templates/overcloud-resource-registry-puppet.j2.yaml`
|
|
|
|
Here is an example of copying a specific resource template and overriding
|
|
so the deployment uses the local version::
|
|
|
|
mkdir local_templates
|
|
cp /usr/share/openstack-tripleo-heat-templates/puppet/controller-puppet.yaml local_templates
|
|
cat > override_templates.yaml << EOF
|
|
resource_registry:
|
|
OS::TripleO::Controller: local_templates/controller-puppet.yaml
|
|
EOF
|
|
openstack overcloud deploy --templates --environment-file override_templates.yaml
|
|
|
|
.. note::
|
|
|
|
The ``--environment-file``/``-e`` option may be specified multiple times,
|
|
if duplicate keys are specified in the environment files, the last one
|
|
takes precedence.
|
|
|
|
.. note::
|
|
|
|
You must also pass the environment files (again using the ``-e`` or
|
|
``--environment-file`` option) whenever you make subsequent changes to the
|
|
overcloud, such as :doc:`../post_deployment/scale_roles`,
|
|
:doc:`../post_deployment/delete_nodes` or
|
|
:doc:`../post_deployment/package_update`.
|
|
|
|
.. _custom-template-location:
|
|
|
|
Using a custom location for all templates
|
|
-----------------------------------------
|
|
|
|
You may specify a path to the ``--templates`` option, such that the packaged
|
|
tree may be copied to another location, which is useful e.g for developer usage
|
|
where you wish to check the templates into a revision control system.
|
|
|
|
.. note::
|
|
|
|
Use caution when using this approach as you will need to rebase any local
|
|
changes on updates to the openstack-tripleo-heat-templates package, and
|
|
care will be needed to avoid modifying anything in the tree which the CLI
|
|
tools rely on (such as top-level parameters). In many cases using the
|
|
:doc:`ExtraConfig <extra_config>` interfaces or specific template overrides
|
|
as outlined above may be preferable.
|
|
|
|
Here is an example of copying the entire tripleo-heat-templates tree to a
|
|
local directory and launching a deployment using the new location::
|
|
|
|
cp -r /usr/share/openstack-tripleo-heat-templates /home/stack/
|
|
openstack overcloud deploy --templates /home/stack/openstack-tripleo-heat-templates
