Dan Wendlandt 555ecd07b0 Devstack support for nicira plugin
Bug 1116847

Includes slight refactoring of L3 logic in main lib/quantum as previous
logic treated l3-agent as only way to do L3, whereas NVP has its own L3
support.

DevStack is a set of scripts and utilities to quickly deploy an OpenStack cloud.

Goals

  • To quickly build dev OpenStack environments in a clean Ubuntu or Fedora environment
  • To describe working configurations of OpenStack (which code branches work together? what do config files look like for those branches?)
  • To make it easier for developers to dive into OpenStack so that they can productively contribute without having to understand every part of the system at once
  • To make it easy to prototype cross-project features
  • To sanity-check OpenStack builds (used in gating commits to the primary repos)

Read more at http://devstack.org (built from the gh-pages branch)

IMPORTANT: Be sure to carefully read stack.sh and any other scripts you execute before you run them, as they install software and may alter your networking configuration. We strongly recommend that you run stack.sh in a clean and disposable vm when you are first getting started.

Devstack on Xenserver

If you would like to use Xenserver as the hypervisor, please refer to the instructions in ./tools/xen/README.md.

Versions

The devstack master branch generally points to trunk versions of OpenStack components. For older, stable versions, look for branches named stable/[release] in the DevStack repo. For example, you can do the following to create a diablo OpenStack cloud:

git checkout stable/diablo
./stack.sh

You can also pick specific OpenStack project releases by setting the appropriate *_BRANCH variables in localrc (look in stackrc for the default set). Usually just before a release there will be milestone-proposed branches that need to be tested::

GLANCE_REPO=https://github.com/openstack/glance.git
GLANCE_BRANCH=milestone-proposed

Start A Dev Cloud

Installing in a dedicated disposable vm is safer than installing on your dev machine! To start a dev cloud:

./stack.sh

When the script finishes executing, you should be able to access OpenStack endpoints, like so:

We also provide an environment file that you can use to interact with your cloud via CLI:

# source openrc file to load your environment with osapi and ec2 creds
. openrc
# list instances
nova list

If the EC2 API is your cup-o-tea, you can create credentials and use euca2ools:

# source eucarc to generate EC2 credentials and set up the environment
. eucarc
# list instances using ec2 api
euca-describe-instances

Customizing

You can override environment variables used in stack.sh by creating file name localrc. It is likely that you will need to do this to tweak your networking configuration should you need to access your cloud from a different host.

Database Backend

Multiple database backends are available. The available databases are defined in the lib/databases directory. mysql is the default database, choose a different one by putting the following in localrc:

disable_service mysql
enable_service postgresql

mysql is the default database.

RPC Backend

Multiple RPC backends are available. Currently, this includes RabbitMQ (default), Qpid, and ZeroMQ. Your backend of choice may be selected via the localrc.

Note that selecting more than one RPC backend will result in a failure.

Example (ZeroMQ):

ENABLED_SERVICES="$ENABLED_SERVICES,-rabbit,-qpid,zeromq"

Example (Qpid):

ENABLED_SERVICES="$ENABLED_SERVICES,-rabbit,-zeromq,qpid"

Swift

Swift is not installed by default, you can enable easily by adding this to your localrc:

enable_service swift

If you want a minimal Swift install with only Swift and Keystone you can have this instead in your localrc:

disable_all_services
enable_service key mysql swift

If you use Swift with Keystone, Swift will authenticate against it. You will need to make sure to use the Keystone URL to auth against.

If you are enabling swift3 in ENABLED_SERVICES devstack will install the swift3 middleware emulation. Swift will be configured to act as a S3 endpoint for Keystone so effectively replacing the nova-objectstore.

Only Swift proxy server is launched in the screen session all other services are started in background and managed by swift-init tool.

By default Swift will configure 3 replicas (and one spare) which could be IO intensive on a small vm, if you only want to do some quick testing of the API you can choose to only have one replica by customizing the variable SWIFT_REPLICAS in your localrc.
