Hironori Shiina 2822e05673 Doc: Remove -r option for running a specific unit test

Now that os-testr was replaced with stestr for running unit tests, -r
options is no longer necessary to pass a regex to the test runner.

Raw Blame History

Developer Quick-Start

This is a quick walkthrough to get you started developing code for Ironic. This assumes you are already familiar with submitting code reviews to an OpenStack project.

The gate currently runs the unit tests under Python 2.7 and Python 3.5. It is strongly encouraged to run the unit tests locally prior to submitting a patch.

Note

Do not run unit tests on the same environment as devstack due to conflicting configuration with system dependencies.

Note

This document is compatible with Python (3.5), Ubuntu (16.04) and Fedora (24). When referring to different versions of Python and OS distributions, this is explicitly stated.

https://docs.openstack.org/infra/manual/developers.html#development-workflow

Prepare Development System

System Prerequisites

The following packages cover the prerequisites for a local development environment on most current distributions. Instructions for getting set up with non-default versions of Python and on older distributions are included below as well.

Ubuntu/Debian:

sudo apt-get install build-essential python-dev libssl-dev python-pip libmysqlclient-dev libxml2-dev libxslt-dev libpq-dev git git-review libffi-dev gettext ipmitool psmisc graphviz libjpeg-dev

Fedora 21/RHEL7/CentOS7:
```
sudo yum install python-devel openssl-devel python-pip mysql-devel libxml2-devel libxslt-devel postgresql-devel git git-review libffi-devel gettext ipmitool psmisc graphviz gcc libjpeg-turbo-devel
```
If using RHEL and yum reports "No package python-pip available" and "No package git-review available", use the EPEL software repository. Instructions can be found at https://fedoraproject.org/wiki/EPEL/FAQ#howtouse.

Fedora 22 or higher:

sudo dnf install python-devel openssl-devel python-pip mysql-devel libxml2-devel libxslt-devel postgresql-devel git git-review libffi-devel gettext ipmitool psmisc graphviz gcc libjpeg-turbo-devel

Additionally, if using Fedora 23, redhat-rpm-config package should be installed so that development virtualenv can be built successfully.

openSUSE/SLE 12:
```
sudo zypper install git git-review libffi-devel libmysqlclient-devel libopenssl-devel libxml2-devel libxslt-devel postgresql-devel python-devel python-nose python-pip gettext-runtime psmisc
```
Graphviz is only needed for generating the state machine diagram. To install it on openSUSE or SLE 12, see https://software.opensuse.org/download.html?project=graphics&package=graphviz-plugins.

Python Prerequisites

If your distro has at least tox 1.8, use similar command to install python-tox package. Otherwise install this on all distros:

sudo pip install -U tox

You may need to explicitly upgrade virtualenv if you've installed the one from your OS distribution and it is too old (tox will complain). You can upgrade it individually, if you need to:

sudo pip install -U virtualenv

Running Unit Tests Locally

If you haven't already, Ironic source code should be pulled directly from git:

# from your home or source directory
cd ~
git clone https://git.openstack.org/openstack/ironic
cd ironic

Running Unit and Style Tests

All unit tests should be run using tox. To run Ironic's entire test suite:

# to run the py27, py35 unit tests, and the style tests
tox

To run a specific test or tests, use the "-e" option followed by the tox target name. For example:

# run the unit tests under py27 and also run the pep8 tests
tox -epy27 -epep8

You may pass options to the test programs using positional arguments. To run a specific unit test, this passes the desired test (regex string) to stestr:

# run a specific test for Python 2.7
tox -epy27 -- test_conductor

Debugging unit tests

In order to break into the debugger from a unit test we need to insert a breaking point to the code:

import pdb; pdb.set_trace()

Then run tox with the debug environment as one of the following:

tox -e debug
tox -e debug test_file_name
tox -e debug test_file_name.TestClass
tox -e debug test_file_name.TestClass.test_name

For more information see the oslotest documentation.

Database Setup

The unit tests need a local database setup, you can use tools/test-setup.sh to set up the database the same way as setup in the OpenStack test systems.

Additional Tox Targets

There are several additional tox targets not included in the default list, such as the target which builds the documentation site. See the tox.ini file for a complete listing of tox targets. These can be run directly by specifying the target name:

# generate the documentation pages locally
tox -edocs

# generate the sample configuration file
tox -egenconfig

Exercising the Services Locally

In addition to running automated tests, sometimes it can be helpful to actually run the services locally, without needing a server in a remote datacenter.

If you would like to exercise the Ironic services in isolation within your local environment, you can do this without starting any other OpenStack services. For example, this is useful for rapidly prototyping and debugging interactions over the RPC channel, testing database migrations, and so forth.

Here we describe two ways to install and configure the dependencies, either run directly on your local machine or encapsulated in a virtual machine or container.

Step 1: Create a Python virtualenv

If you haven't already downloaded the source code, do that first:

cd ~
git clone https://git.openstack.org/openstack/ironic
cd ironic

Create the Python virtualenv:
```
tox -evenv --notest --develop -r
```
Activate the virtual environment:
```
. .tox/venv/bin/activate
```
Install the openstack client command utility:
```
pip install python-openstackclient
```
Install the openstack baremetal client:
```
pip install python-ironicclient
```
Note

You can install python-ironicclient from source by cloning the git repository and running pip install . while in the root of the cloned repository.
Export some ENV vars so the client will connect to the local services that you'll start in the next section:
```
export OS_TOKEN=fake-token
export OS_URL=http://localhost:6385/
```

Next, install and configure system dependencies. Two different approaches are described below; you should only do one of these.

Step 2a: System Dependencies In A Virtual Machine

This option requires virtualbox, vagrant, and ansible. You may install these using your favorite package manager, or by downloading from the provided links.

Let vagrant do the work:
```
vagrant up
```

This will create a VM available to your local system at 192.168.99.11, will install all the necessary service dependencies, and configure some default users. It will also generate ./etc/ironic/ironic.conf.local preconfigured for local dev work. We recommend you compare and familiarize yourself with the settings in ./etc/ironic/ironic.conf.sample so you can adjust it to meet your own needs.

Step 2b: Install System Dependencies Locally

This option will install RabbitMQ and MySQL on your local system. This may not be desirable in some situations (eg, you're developing from a laptop and do not want to run a MySQL server on it all the time).

Install rabbitmq-server:

# install rabbit message broker
# Ubuntu/Debian:
sudo apt-get install rabbitmq-server

# Fedora 21/RHEL7/CentOS7:
sudo yum install rabbitmq-server
sudo systemctl start rabbitmq-server.service

# Fedora 22 or higher:
sudo dnf install rabbitmq-server
sudo systemctl start rabbitmq-server.service

# openSUSE/SLE 12:
sudo zypper install rabbitmq-server
sudo systemctl start rabbitmq-server.service

Install mysql-server:

# Ubuntu/Debian:
# sudo apt-get install mysql-server

# Fedora 21/RHEL7/CentOS7:
# sudo yum install mariadb mariadb-server
# sudo systemctl start mariadb.service

# Fedora 22 or higher:
# sudo dnf install mariadb mariadb-server
# sudo systemctl start mariadb.service

# openSUSE/SLE 12:
# sudo zypper install mariadb
# sudo systemctl start mysql.service

# If using MySQL, you need to create the initial database
mysql -u root -pMYSQL_ROOT_PWD -e "create schema ironic"

Note

if you choose not to install mysql-server, ironic will default to using a local sqlite database.

Create a configuration file within the ironic source directory:

# generate a sample config
tox -egenconfig

# copy sample config and modify it as necessary
cp etc/ironic/ironic.conf.sample etc/ironic/ironic.conf.local

# disable auth since we are not running keystone here
sed -i "s/#auth_strategy = keystone/auth_strategy = noauth/" etc/ironic/ironic.conf.local

# use the 'fake-hardware' test hardware type
sed -i "s/#enabled_hardware_types = .*/enabled_hardware_types = fake-hardware/" etc/ironic/ironic.conf.local

# use the 'fake' deploy and boot interfaces
sed -i "s/#enabled_deploy_interfaces = .*/enabled_deploy_interfaces = fake/" etc/ironic/ironic.conf.local
sed -i "s/#enabled_boot_interfaces = .*/enabled_boot_interfaces = fake/" etc/ironic/ironic.conf.local

# enable both fake and ipmitool management and power interfaces
sed -i "s/#enabled_management_interfaces = .*/enabled_management_interfaces = fake,ipmitool/" etc/ironic/ironic.conf.local
sed -i "s/#enabled_power_interfaces = .*/enabled_power_interfaces = fake,ipmitool/" etc/ironic/ironic.conf.local

# set a fake host name [useful if you want to test multiple services on the same host]
sed -i "s/#host = .*/host = test-host/" etc/ironic/ironic.conf.local

# change the periodic sync_power_state_interval to a week, to avoid getting NodeLocked exceptions
sed -i "s/#sync_power_state_interval = 60/sync_power_state_interval = 604800/" etc/ironic/ironic.conf.local

# if you opted to install mysql-server, switch the DB connection from sqlite to mysql
sed -i "s/#connection = .*/connection = mysql\+pymysql:\/\/root:MYSQL_ROOT_PWD@localhost\/ironic/" etc/ironic/ironic.conf.local

Step 3: Start the Services

From within the python virtualenv, run the following command to prepare the database before you start the ironic services:

# initialize the database for ironic
ironic-dbsync --config-file etc/ironic/ironic.conf.local create_schema

Next, open two new terminals for this section, and run each of the examples here in a separate terminal. In this way, the services will not be run as daemons; you can observe their output and stop them with Ctrl-C at any time.

Start the API service in debug mode and watch its output:

cd ~/ironic
. .tox/venv/bin/activate
ironic-api -d --config-file etc/ironic/ironic.conf.local

Start the Conductor service in debug mode and watch its output:

cd ~/ironic
. .tox/venv/bin/activate
ironic-conductor -d --config-file etc/ironic/ironic.conf.local

Step 4: Interact with the running services

You should now be able to interact with ironic via the python client, which is present in the python virtualenv, and observe both services' debug outputs in the other two windows. This is a good way to test new features or play with the functionality without necessarily starting DevStack.

To get started, export the following variables to point the client at the local instance of ironic and disable the authentication:

export OS_AUTH_TYPE=token_endpoint
export OS_TOKEN=fake
export OS_ENDPOINT=http://127.0.0.1:6385

Then list the available commands and resources:

# get a list of available commands
openstack help baremetal

# get the list of drivers currently supported by the available conductor(s)
openstack baremetal driver list

# get a list of nodes (should be empty at this point)
openstack baremetal node list

Here is an example walkthrough of creating a node:

MAC="aa:bb:cc:dd:ee:ff"   # replace with the MAC of a data port on your node
IPMI_ADDR="1.2.3.4"       # replace with a real IP of the node BMC
IPMI_USER="admin"         # replace with the BMC's user name
IPMI_PASS="pass"          # replace with the BMC's password

# enroll the node with the fake hardware type and IPMI-based power and
# management interfaces. Note that driver info may be added at node
# creation time with "--driver-info"
NODE=$(openstack baremetal node create \
       --driver fake-hardware \
       --management-interface ipmitool \
       --power-interface ipmitool \
       --driver-info ipmi_address=$IPMI_ADDR \
       --driver-info ipmi_username=$IPMI_USER \
       -f value -c uuid)

# driver info may also be added or updated later on
openstack baremetal node set $NODE --driver-info ipmi_password=$IPMI_PASS

# add a network port
openstack baremetal port create $MAC --node $NODE

# view the information for the node
openstack baremetal node show $NODE

# request that the node's driver validate the supplied information
openstack baremetal node validate $NODE

# you have now enrolled a node sufficiently to be able to control
# its power state from ironic!
openstack baremetal node power on $NODE

If you make some code changes and want to test their effects, simply stop the services with Ctrl-C and restart them.

Step 5: Fixing your test environment

If you are testing changes that add or remove python entrypoints, or making significant changes to ironic's python modules, or simply keep the virtualenv around for a long time, your development environment may reach an inconsistent state. It may help to delete cached ".pyc" files, update dependencies, reinstall ironic, or even recreate the virtualenv. The following commands may help with that, but are not an exhaustive troubleshooting guide:

# clear cached pyc files
cd ~/ironic/ironic
find ./ -name '*.pyc' | xargs rm

# reinstall ironic modules
cd ~/ironic
. .tox/venv/bin/activate
pip uninstall ironic
pip install -e .

# install and upgrade ironic and all python dependencies
cd ~/ironic
. .tox/venv/bin/activate
pip install -U -e .

Deploying Ironic with DevStack

DevStack may be configured to deploy Ironic, setup Nova to use the Ironic driver and provide hardware resources (network, baremetal compute nodes) using a combination of OpenVSwitch and libvirt. It is highly recommended to deploy on an expendable virtual machine and not on your personal work station. Deploying Ironic with DevStack requires a machine running Ubuntu 16.04 (or later) or Fedora 24 (or later). Make sure your machine is fully up to date and has the latest packages installed before beginning this process.

https://docs.openstack.org/devstack/latest/

Note

The devstack "demo" tenant is now granted the "baremetal_observer" role and thereby has read-only access to ironic's API. This is sufficient for all the examples below. Should you want to create or modify bare metal resources directly (ie. through ironic rather than through nova) you will need to use the devstack "admin" tenant.

Devstack will no longer create the user 'stack' with the desired permissions, but does provide a script to perform the task:

git clone https://git.openstack.org/openstack-dev/devstack.git devstack
sudo ./devstack/tools/create-stack-user.sh

Switch to the stack user and clone DevStack:

sudo su - stack
git clone https://git.openstack.org/openstack-dev/devstack.git devstack

Create devstack/local.conf with minimal settings required to enable Ironic. An example local.conf that enables both direct and iscsi deploy interfaces </admin/interfaces/deploy> and uses the ipmi hardware type by default:

cd devstack
cat >local.conf <<END
[[local|localrc]]
# Credentials
ADMIN_PASSWORD=password
DATABASE_PASSWORD=password
RABBIT_PASSWORD=password
SERVICE_PASSWORD=password
SERVICE_TOKEN=password
SWIFT_HASH=password
SWIFT_TEMPURL_KEY=password

# Enable Ironic plugin
enable_plugin ironic git://git.openstack.org/openstack/ironic

# Disable nova novnc service, ironic does not support it anyway.
disable_service n-novnc

# Enable Swift for the direct deploy interface.
enable_service s-proxy
enable_service s-object
enable_service s-container
enable_service s-account

# Disable Horizon
disable_service horizon

# Disable Cinder
disable_service cinder c-sch c-api c-vol

# Swift temp URL's are required for the direct deploy interface
SWIFT_ENABLE_TEMPURLS=True

# Create 3 virtual machines to pose as Ironic's baremetal nodes.
IRONIC_VM_COUNT=3
IRONIC_BAREMETAL_BASIC_OPS=True
DEFAULT_INSTANCE_TYPE=baremetal

# Enable additional hardware types, if needed.
#IRONIC_ENABLED_HARDWARE_TYPES=ipmi,fake-hardware
# Don't forget that many hardware types require enabling of additional
# interfaces, most often power and management:
#IRONIC_ENABLED_MANAGEMENT_INTERFACES=ipmitool,fake
#IRONIC_ENABLED_POWER_INTERFACES=ipmitool,fake
# The 'ipmi' hardware type's default deploy interface is 'iscsi'.
# This would change the default to 'direct':
#IRONIC_DEFAULT_DEPLOY_INTERFACE=direct

# Change this to alter the default driver for nodes created by devstack.
# This driver should be in the enabled list above.
IRONIC_DEPLOY_DRIVER=ipmi

# The parameters below represent the minimum possible values to create
# functional nodes.
IRONIC_VM_SPECS_RAM=1280
IRONIC_VM_SPECS_DISK=10

# Size of the ephemeral partition in GB. Use 0 for no ephemeral partition.
IRONIC_VM_EPHEMERAL_DISK=0

# To build your own IPA ramdisk from source, set this to True
IRONIC_BUILD_DEPLOY_RAMDISK=False

VIRT_DRIVER=ironic

# By default, DevStack creates a 10.0.0.0/24 network for instances.
# If this overlaps with the hosts network, you may adjust with the
# following.
NETWORK_GATEWAY=10.1.0.1
FIXED_RANGE=10.1.0.0/24
FIXED_NETWORK_SIZE=256

# Log all output to files
LOGFILE=$HOME/devstack.log
LOGDIR=$HOME/logs
IRONIC_VM_LOG_DIR=$HOME/ironic-bm-logs

END

Note

Git protocol requires access to port 9418, which is not a standard port that corporate firewalls always allow. If you are behind a firewall or on a proxy that blocks Git protocol, modify the enable_plugin line to use https:// instead of git:// and add GIT_BASE=https://git.openstack.org to the credentials:

GIT_BASE=https://git.openstack.org

# Enable Ironic plugin enable_plugin ironic https://git.openstack.org/openstack/ironic

Note

When the ipmi hardware type is used and IRONIC_IS_HARDWARE variable is false devstack will automatically set up VirtualBMC to control the power state of the virtual baremetal nodes.

Note

When running QEMU as non-root user (e.g. qemu on Fedora or libvirt-qemu on Ubuntu), make sure IRONIC_VM_LOG_DIR points to a directory where QEMU will be able to write. You can verify this with, for example:

# on Fedora

sudo -u qemu touch $HOME/ironic-bm-logs/test.log # on Ubuntu sudo -u libvirt-qemu touch $HOME/ironic-bm-logs/test.log

Note

To check out an in-progress patch for testing, you can add a Git ref to the enable_plugin line. For instance:

enable_plugin ironic git://git.openstack.org/openstack/ironic refs/changes/46/295946/15

For a patch in review, you can find the ref to use by clicking the "Download" button in Gerrit. You can also specify a different git repo, or a branch or tag:

enable_plugin ironic https://github.com/openstack/ironic stable/kilo

For more details, see the devstack plugin interface documentation.

Run stack.sh:

./stack.sh

Source credentials, create a key, and spawn an instance as the demo user:

. ~/devstack/openrc

# query the image id of the default cirros image
image=$(openstack image show $DEFAULT_IMAGE_NAME -f value -c id)

# create keypair
ssh-keygen
openstack keypair create --public-key ~/.ssh/id_rsa.pub default

# spawn instance
openstack server create --flavor baremetal --image $image --key-name default testing

Note

Because devstack create multiple networks, we need to pass an additional parameter --nic net-id to the nova boot command when using the admin account, for example:

net_id=$(openstack network list | egrep "$PRIVATE_NETWORK_NAME"'[^-]' | awk '{ print $2 }')

openstack server create --flavor baremetal --nic net-id=$net_id --image $image --key-name default testing

You should now see a Nova instance building:

openstack server list --long

+----------+---------+--------+------------+-------------+----------+------------+----------+-------------------+------+------------+

Nova will be interfacing with Ironic conductor to spawn the node. On the Ironic side, you should see an Ironic node associated with this Nova instance. It should be powered on and in a 'wait call-back' provisioning state:

openstack baremetal node list
+--------------------------------------+--------+--------------------------------------+-------------+--------------------+-------------+
| UUID                                 | Name   | Instance UUID                        | Power State | Provisioning State | Maintenance |
+--------------------------------------+--------+--------------------------------------+-------------+--------------------+-------------+
| 9e592cbe-e492-4e4f-bf8f-4c9e0ad1868f | node-0 | None                                 | power off   | None               | False       |
| ec0c6384-cc3a-4edf-b7db-abde1998be96 | node-1 | None                                 | power off   | None               | False       |
| 4099e31c-576c-48f8-b460-75e1b14e497f | node-2 | a2c7f812-e386-4a22-b393-fe1802abd56e | power on    | wait call-back     | False       |
+--------------------------------------+--------+--------------------------------------+-------------+--------------------+-------------+

At this point, Ironic conductor has called to libvirt (via virtualbmc) to power on a virtual machine, which will PXE + TFTP boot from the conductor node and progress through the Ironic provisioning workflow. One libvirt domain should be active now:

sudo virsh list --all
 Id    Name                           State
----------------------------------------------------
 2     node-2                         running
 -     node-0                         shut off
 -     node-1                         shut off

This provisioning process may take some time depending on the performance of the host system, but Ironic should eventually show the node as having an 'active' provisioning state:

openstack baremetal node list
+--------------------------------------+--------+--------------------------------------+-------------+--------------------+-------------+
| UUID                                 | Name   | Instance UUID                        | Power State | Provisioning State | Maintenance |
+--------------------------------------+--------+--------------------------------------+-------------+--------------------+-------------+
| 9e592cbe-e492-4e4f-bf8f-4c9e0ad1868f | node-0 | None                                 | power off   | None               | False       |
| ec0c6384-cc3a-4edf-b7db-abde1998be96 | node-1 | None                                 | power off   | None               | False       |
| 4099e31c-576c-48f8-b460-75e1b14e497f | node-2 | a2c7f812-e386-4a22-b393-fe1802abd56e | power on    | active             | False       |
+--------------------------------------+--------+--------------------------------------+-------------+--------------------+-------------+

This should also be reflected in the Nova instance state, which at this point should be ACTIVE, Running and an associated private IP:

openstack server list --long
+----------+---------+--------+------------+-------------+---------------+------------+----------+-------------------+------+------------+

Running Tempest tests

After Deploying Ironic with DevStack one might want to run integration tests against the running cloud. The Tempest project is the project that offers an integration test suite for OpenStack.

First, navigate to Tempest directory:

cd /opt/stack/tempest

To run all tests from the Ironic plugin, execute the following command:

tox -e all-plugin -- ironic

To limit the amount of tests that you would like to run, you can use a regex. For instance, to limit the run to a single test file, the following command can be used:

tox -e all-plugin -- ironic_tempest_plugin.tests.scenario.test_baremetal_basic_ops

Debugging Tempest tests

It is sometimes useful to step through the test code, line by line, especially when the error output is vague. This can be done by running the tests in debug mode and using a debugger such as pdb.

For example, after editing the test_baremetal_basic_ops file and setting up the pdb traces you can invoke the run_tempest.sh script in the Tempest directory with the following parameters:

./run_tempest.sh -N -d ironic_tempest_plugin.tests.scenario.test_baremetal_basic_ops

The -N parameter tells the script to run the tests in the local environment (without a virtualenv) so it can find the Ironic tempest plugin.
The -d parameter enables the debug mode, allowing it to be used with pdb.

For more information about the supported parameters see:

./run_tempest.sh --help

Note

Always be careful when running debuggers in time sensitive code, they may cause timeout errors that weren't there before.

OSProfiler Tracing in Ironic

OSProfiler is an OpenStack cross-project profiling library. It is being used among OpenStack projects to look at performance issues and detect bottlenecks. For details on how OSProfiler works and how to use it in ironic, please refer to OSProfiler Support Documentation.

Building developer documentation

If you would like to build the documentation locally, eg. to test your documentation changes before uploading them for review, run these commands to build the documentation set:

On your local machine:

# activate your development virtualenv
. .tox/venv/bin/activate

# build the docs
tox -edocs

#Now use your browser to open the top-level index.html located at:

ironic/doc/build/html/index.html

On a remote machine:

# Go to the directory that contains the docs
cd ~/ironic/doc/source/

# Build the docs
tox -edocs

# Change directory to the newly built HTML files
cd ~/ironic/doc/build/html/

# Create a server using python on port 8000
python -m SimpleHTTPServer 8000

#Now use your browser to open the top-level index.html located at:

http://your_ip:8000
