+=====================================
+Resource Constraints in Kolla Ansible
+=====================================
+
+Overview
+~~~~~~~~
+
+Since the Rocky release it is possible to restrict
+the resource usage of deployed containers.
+The following components support this feature:
+
+* Nova
+
+In Kolla Ansible,
+container resources to be constrained are referred to as dimensions.
+
+The `Docker documentation <https://docs.docker.com/config/containers/resource_constraints/>`__
+provides information on container resource constraints.
+The resources currently supported by Kolla Ansible are:
+
+.. code-block:: console
+
+    cpu_period
+    cpu_quota
+    cpu_shares
+    cpuset_cpus
+    cpuset_mems
+    mem_limit
+    mem_reservation
+    memswap_limit
+    kernel_memory
+    blkio_weight
+
+.. end
+
+Pre-deployment Configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Dimensions are defined as a mapping from a Docker resource name
+(e.g. ``cpu_period``) to a string constraint value.
+
+The variable ``default_container_dimensions`` sets the default dimensions
+for all supported containers, and by default these are unconstrained.
+
+Each supported container has an associated variable,
+``<container name>_dimensions``, that can be used to set the resources
+for the container. For example, dimensions for the ``nova_libvirt``
+container are set via the variable ``nova_libvirt_dimensions``.
+
+For example,
+to constrain the number of CPUs that may be used by all supported containers,
+add the following to the dimensions options section in
+``/etc/kolla/globals.yml``:
+
+.. code-block:: yaml
+
+   default_container_dimensions:
+     cpuset_cpus: "1"
+
+.. end
+
+For example, to constrain the number of CPUs that may be used by
+the ``nova_libvirt`` container, add the following to the dimensions
+options section in ``/etc/kolla/globals.yml``:
+
+.. code-block:: yaml
+
+   nova_libvirt_dimensions:
+     cpuset_cpus: "2"
+
+.. end
+
+Deployment
+~~~~~~~~~~
+
+To deploy resource constrained containers, run the deployment as usual:
+
+.. code-block:: console
+
+  $ kolla-ansible deploy -i /path/to/inventory
+
+.. end
