.. _heat-dev-env:
=================================
Development Environment with Heat
=================================
These `Heat <https://wiki.openstack.org/wiki/Heat>`__ templates will
deploy an *N*-node `Kolla <https://wiki.openstack.org/Kolla>`__ cluster,
where *N* is the value of the ``number_of_nodes`` parameter you specify
when creating the stack.
Kolla has recently undergone a considerable design change. The details
of the design change is addressed in this
`spec <https://review.openstack.org/#/c/153798/>`__. As part of the
design change, containers share pid and networking namespaces with the
Docker host. Therefore, containers no longer connect to a docker0 bridge
and have separate networking from the host. As a result, Kolla
networking has a configuration similar to:
.. image:: kollanet.png
:alt: Kolla networking
Sharing pid and networking namespaces is detailed in the `super
privileged
containers <http://sdake.io/2015/01/28/an-atomic-upgrade-process-for-openstack-compute-nodes/>`__
concept.
The Kolla cluster is based on Fedora 21, requires the minimum Docker
version of 1.7.0
`binary <https://docs.docker.com/installation/binaries/>`__.
These templates are designed to work with the Icehouse or Juno versions
of Heat. If using Icehouse Heat, this
`patch <https://review.openstack.org/#/c/121139/>`__ is required to
correct a bug with template validation when using the "Fn::Join"
function).
Create the Glance Image
=======================
After cloning the project, run the get-image.sh script from the
project's devenv directory:
::
$ ./get-image.sh
The script will create a Fedora 21 image with the required
modifications.
Add the image to your Glance image store:
::
$ glance image-create --name "fedora-21-x86_64" \
--file /var/lib/libvirt/images/fedora-21-x86_64 \
--disk-format qcow2 --container-format bare \
--is-public True --progress
Create the Stack
================
Copy local.yaml.example to local.yaml and edit the contents to match
your deployment environment. Here is an example of a customized
local.yaml:
::
parameters:
ssh_key_name: admin-key
external_network_id: 028d70dd-67b8-4901-8bdd-0c62b06cce2d
container_external_network_id: 028d70dd-67b8-4901-8bdd-0c62b06cce2d
container_external_subnet_id: 575770dd-6828-1101-34dd-0c62b06fjf8s
dns_nameserver: 192.168.200.1
The external\_network\_id is used by Heat to automatically assign
floating IP's to your Kolla nodes. You can then access your Kolla nodes
directly using the floating IP. The network ID is derived from the
``neutron net-list`` command.
The container\_external\_network\_id is used by the nova-network
container within the Kolla node as the FLAT\_INTERFACE. The
FLAT\_INTERFACE tells Nova what device to use (i.e. eth1) to pass
network traffic between Nova instances across Kolla nodes. This network
should be separate from the external\_network\_id above and is derived
from the 'neutron net-list' command.
The container\_external\_subnet\_id: is the subnet equivalent to
container\_external\_network\_id
Review the parameters section of kollacluster.yaml for a full list of
configuration options.
.. note:: You must provide values for:
- ``ssh_key_name``
- ``external_network_id``
- ``container_external_network_id``
- ``container_external_subnet_id``
And then create the stack, referencing that environment file:
::
$ openstack stack create -f kollacluster.yaml -e local.yaml kolla-cluster
Access the Kolla Nodes
======================
You can get the ip address of the Kolla nodes using the
``openstack stack output show`` command:
::
$ openstack stack output show kolla-cluster kolla_node_external_ip
"192.168.200.86"
You can ssh into that server as the ``fedora`` user:
::
$ ssh fedora@192.168.200.86
Once logged into your Kolla node, setup your environment. The basic
starting environment will be created using ``docker-compose``. This
environment will start up the openstack services listed in the compose
directory.
To start, setup your environment variables.
::
$ cd kolla
$ ./tools/genenv
The ``genenv`` script will create a compose/openstack.env file and an
openrc file in your current directory. The openstack.env file contains
all of your initialized environment variables, which you can edit for a
different setup.
Next, run the start script.
::
$ ./tools/kolla-compose start
The ``start`` script is responsible for starting the containers using
``docker-compose -f <osp-service-container> up -d``.
If you want to start a container set by hand use this template
::
$ docker-compose -f glance-api-registry.yml up -d
Debugging
=========
All Docker commands should be run from the directory of the Docker
binary, by default this is ``/``.
A few commands for debugging the system.
::
$ sudo ./docker images
Lists all images that have been pulled from the upstream kolla
repository thus far. This can be run on the node during the ``./start``
operation to check on the download progress.
::
$ sudo ./docker ps -a
This will show all processes that docker has started. Removing the
``-a`` will show only active processes. This can be run on the node
during the ``./start`` operation to check that the containers are
orchestrated.
::
$ sudo ./docker logs <containerid>
::
$ curl http://<NODE_IP>:3306
You can use curl to test connectivity to a container. This example
demonstrates the Mariadb service is running on the node. Output should
appear as follows
::
$ curl http://10.0.0.4:3306
Trying 10.0.0.4...
Connected to 10.0.0.4.
Escape character is '^]'.

@ -360,23 +360,10 @@ Two virtualized development environment options are available for Kolla. These
options permit the development of Kolla without disrupting the host operating
system.
If developing Kolla on an OpenStack cloud environment that supports Heat,
follow the :doc:`heat-dev-env`.
If developing Kolla on a system that provides VirtualBox or Libvirt in addition
to Vagrant, use the Vagrant virtual environment documented in
:doc:`vagrant-dev-env`.
Currently the Heat development environment is entirely non-functional. The
Kolla core reviewers have debated removing it from the repository but have
resisted to provide an opportunity for contributors to make Heat usable for
Kolla development. The Kolla core reviewers believe Heat would offer a great
way to develop Kolla in addition to Vagrant, bare metal, or a manually setup
virtual machine.
