Testing a Openstack Installation with tempest on Debian GNU/Linux

Scope of this howto

This page explains how to test a Openstack Cluster installation on Debian

The Tempest tools will be used to test the installation and the stability of the cluster.

The s3-tests tools to test the s3 compatibility.


In formatted blocks :


Setup the dependencies:

# apt-get install -y git python-nose python-anyjson python-unittest2 python-lxml python-boto openstack-clients python-paramiko python-netifaces python-webob python-virtualenv python-dev libevent-dev python-sqlalchemy 

Prepare materials for Glance/Nova API

NB: we assume that Openstack environment variables (OS_USERNAME, OS_TENANT_NAME, OS_PASSWORD and OS_AUTH_URL) are set with a admin account.

Prepare materials for EC2 API

#TODO: create all manifest.xml files

Create two users for tempest test:

# keystone role-list | grep Member

# keystone tenant-create --name demo | awk '/id/{print $4}'

All ids generated here will be used in tempest and s3tests configuration.

Tempest Installation/Configuration

Clone the git repository

# git clone https://github.com/openstack/tempest.git

Prepare the configuration file

cp /root/tempest/etc/tempest.conf.sample /root/tempest/etc/tempest.conf

Edit the following fields in /root/tempest/etc/tempest.conf, and replace <VALUE> by the value that match your configuration.

nb: identity/host define field "host" in section "[identity"]

identity/host = <KEYSTONE_HOST>
identity/port = <KEYSTONE_PORT>
identity-admin/username = admin
identify-admin/password = <THE_ADMIN_PASSWORD>
identity-admin/tenant_name = <THE_ADMIN_TENANT>

compute-admin/username = admin
compute-admin/password = <THE_ADMIN_PASSWORD>
compute-admin/tenant_name = <THE_ADMIN_TENANT>
compute/whitebox_enabled = false       # this disable tests inside VM
compute/resize_available = false       # disable it only if your cluster don't support resize

image/host = <GLANCE_HOST>
image/host = <GLANCE_PORT>

boto/ec2_url = <URL_OF_THE_EC2_API>    # ie: http://identity.mystack.net:8773/services/Cloud
boto/s3_url = <URL_OF_THE_S3_API>      # ie: http://storage.mystack.net:8080
boto/aws_access = fd158f8c4841411f8ec0b1500b8c3c16  # access_key for the demo account
boto/aws_secret = e6563c4efcc14c418f20262e92e8bfa9  # secret_key for the demo account
boto/s3_materials_path = /root/s3-materials

Tempest run

Go in the tempest directory

cd /root/tempest

Run all tests with:

nosetests tempest/tests/

Or only some of them with:

For keystone:

# nosetests tempest/tests/identity
Ran 147 tests in 18.202s

OK (SKIP=13)

For swift:

nosetests tempest/tests/object_storage

Ran 17 tests in 2.389s


s3tests Installation/Configuration

Clone the git repository

git clone  https://github.com/ceph/s3-tests.git

Create the configuration file /root/s3-tests/s3.conf and replace all ids by the one generated previously:

## this section is just used as default for all the "s3 *"
## sections, you can place these variables also directly there

## replace with e.g. "localhost" to run against local software
host = storage.mystack.net
port = 8080

## say "no" to disable TLS
is_secure = no

## all the buckets created will start with this prefix;
## {random} will be filled with random characters to pad
## the prefix to 30 characters long, and avoid collisions
bucket prefix = s3test-{random}-

[s3 main]
## the tests assume two accounts are defined, "main" and "alt".

## user_id is a 64-character hexstring
user_id = ea80cb1a216c44f1845e6fe9d1025ac2

## display name typically looks more like a unix login, "jdoe" etc
display_name = demo

## replace these with your access keys
access_key = fd158f8c4841411f8ec0b1500b8c3c16
secret_key = e6563c4efcc14c418f20262e92e8bfa9

[s3 alt]
## another user account, used for ACL-related tests
user_id = bfe2b7da10034329b04caef5d12345a8
display_name = alt-demo
email = alt-demo@demo.com
access_key = ed1adcfcc7994445a290ac1c8ab13621
secret_key = 066b237eabe946d2a1c83f1ff61aaccb

s3tests run

# cd s3-tests
# S3TEST_CONF=s3.conf ./virtualenv/bin/nosetests

Ran 256 tests in 477.413s

FAILED (errors=40, failures=50)

This result come from a Folsom Openstack Cluster, all S3 tests did not work correctly yet.
