Overview

Devtest is a script that creates a development environment for TripleO / Tuskar / TuskarUI development. Below you can find step-by-step instructions for setting up the environment using devtest. If you would like more information about how devtest works as well as the script itself, see the following links

However, following the steps below should lead to a complete functioning setup.

Instructions

All commands (unless otherwise specified) should be run as root, in a dedicated machine you will use for TripleO development. We will call this machine "the lab machine" or "the lab server". The setup has been tested with lab machines running Fedora 19.

Install git and kvm. Installing kvm at this point sets the ownership of the /dev/kvm correctly (it should be owned by the root user and kvm group). If you don't do this, devtest will fail due to incorrectly set ownership of /dev/kvm.

yum -y install git kvm

Create devtest configuration file:

cat <<'EOF' > ~/.devtestrc
export NODE_CPU=1 NODE_MEM=4096 NODE_DISK=20 NODE_ARCH=amd64
export NODE_DIST="fedora selinux-permissive"
export DIB_RELEASE=19
export UNDERCLOUD_DIB_EXTRA_ARGS=""
export OVERCLOUD_DIB_EXTRA_ARGS=""
EOF

Clone the tripleo-incubator repo and run the devtest script:

export TRIPLEO_ROOT=~/tripleo
mkdir -p $TRIPLEO_ROOT
cd $TRIPLEO_ROOT
git clone https://git.openstack.org/openstack/tripleo-incubator
$TRIPLEO_ROOT/tripleo-incubator/scripts/devtest.sh --trash-my-machine
# wait around 2+ hours
# mawagner: if openvswitch fails to start, see https://bugzilla.redhat.com/show_bug.cgi?id=1006412 (or just mkdir /var/lock/subsys)

At this point, your devtest environment is configured. To proceed, you need to install Horizon and Tuskar-UI, since they are not installed by devtest. To do this, you have 2 options:

  • you can install and configure Horizon and Tuskar-UI in the undercloud

or

  • you can install and configure Horizon and Tuskar-UI on the lab machine

Option 1: Horizon and Tuskar-UI in the undercloud

SSH into seed machine and flush iptables rules:

ssh root@192.0.2.1
iptables -F # or set NAT masqurade in iptables http://www.revsys.com/writings/quicktips/nat.html
exit

SSH into the undercloud and enable internet there:

ssh heat-admin@192.0.2.2
sudo -i
echo "nameserver 192.168.122.1" >> /etc/resolv.conf

Install and configure Horizon and Tuskar-UI:

easy_install pip
easy_install nose
cd /opt/stack
git clone git://github.com/openstack/horizon.git 
git clone git://github.com/openstack/tuskar-ui.git
cd horizon
python tools/install_venv.py
./run_tests.sh
cp ../tuskar-ui/local_settings.py.example openstack_dashboard/local/local_settings.py
tools/with_venv.sh pip install -r ../tuskar-ui/requirements.txt
tools/with_venv.sh pip install -e ../tuskar-ui/
cp ../tuskar-ui/_50_tuskar.py.example openstack_dashboard/local/enabled/_50_tuskar.py

Open the port 8111 since that is where we will run the development web server:

iptables -F # or iptables -I INPUT -p tcp --dport 8111 -j ACCEPT

Start the server:

tools/with_venv.sh ./manage.py runserver 0.0.0.0:8111

Create an SSH tunnel so you can see the UI from your browser. This next command should be run on your local machine, replacing 'lab-machine' with the hostname of your lab machine:

ssh -L 8111:192.0.2.2:8111 root@lab-machine

Now you can see the UI from your browser (you can find credentials for dashboard in undercloud machine in /root/stackrc):

localhost:8111

The rest of this section explains how to setup the sshfs, if you want to edit your code locally. All the commands below should be run on your local machine, replacing 'lab-machine' with the hostname of your lab machine'. First tunnel to lab machine on port 22:

ssh -L 2222:192.0.2.2:22 root@lab-machine
# add your local machine's public key to undercloud's /root/.ssh/authorized_keys 

Then make sshfs from your local machine:

yum install -y sshfs && mkdir -p ~/devtest
sshfs -p 2222 root@localhost:/opt/stack/ ~/devtest

Option 2: Horizon and Tuskar-UI on the lab machine

Install and configure Horizon and Tuskar-UI:

easy_install pip
easy_install nose
cd /opt/stack
git clone git://github.com/openstack/horizon.git 
git clone git://github.com/openstack/tuskar-ui.git
cd horizon
python tools/install_venv.py
./run_tests.sh
cp ../tuskar-ui/local_settings.py.example openstack_dashboard/local/local_settings.py
tools/with_venv.sh pip install -r ../tuskar-ui/requirements.txt
tools/with_venv.sh pip install -e ../tuskar-ui/
cp ../tuskar-ui/_50_tuskar.py.example openstack_dashboard/local/enabled/_50_tuskar.py

Copy /root/stackrc from the undercloud to the lab machine, change the OS_AUTH_URL to point to the undercloud, and source it:

ssh heat-admin@192.0.2.2 "sudo -i cat /root/stackrc" > /root/stackrc
sed -i 's/localhost:5000/192.0.2.2:5000/' /root/stackrc
source /root/stackrc

Configure OPENSTACK_HOST in horizon settings to point to the undercloud machine:

sed -i 's/OPENSTACK_HOST = "127.0.0.1"/OPENSTACK_HOST = "192.0.2.2"/' /opt/stack/horizon/openstack_dashboard/local/local_settings.py

Start the server:

tools/with_venv.sh ./manage.py runserver 0.0.0.0:8111

Now you can see the UI from your browser (you can find credentials for dashboard in undercloud machine in /root/stackrc):

lab-machine:8111
