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

Setup devtest

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.

Note: You might want to move the location of the default libvirt storage pool. The default location is /var/lib/libvirt/images. Depending on your file system / partitions setup, there might not be enough space for images at this default location. To be on the safe side, you can move it to another location which has plenty of space. Below is an example how to move the default storage pool location to /home/images. If you are sure that there is enough space at the default location, you can skip this step.

mkdir /home/images
yum install -y libvirt
service libvirtd start
virsh pool-destroy default
virsh pool-undefine default
virsh pool-define-as default dir --target /home/images
virsh pool-start default
virsh pool-autostart default
service libvirtd restart

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

Check access rights on /dev/kvm afterwards. If group is not kvm or group doesn't have rw on this file, execute the following commands and reboot:

chgrp kvm /dev/kvm
chmod g+rw /dev/kvm

Create devtest configuration file:

cat <<'EOF' > ~/.devtestrc
export NODE_CPU=1 NODE_MEM=4096 NODE_DISK=60 NODE_ARCH=amd64
export NODE_DIST="fedora selinux-permissive"
export DIB_RELEASE=20
export UNDERCLOUD_DIB_EXTRA_ARGS=""
export OVERCLOUD_DIB_EXTRA_ARGS=""
export OVERCLOUD_COMPUTESCALE=1
export TRIPLEO_CLEANUP=1
export USE_IRONIC=1
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)

If you want to e.g. redeploy Overcloud for testing purposes, you will need to source following

source tripleo-incubator/scripts/devtest_variables.sh
source ./tripleo-undercloud-passwords
source ./tripleo-incubator/undercloudrc
source $TRIPLEO_ROOT/tripleo-incubator/cloudprompt
source ~/.devtestrc

Build the block storage image

$TRIPLEO_ROOT/diskimage-builder/bin/disk-image-create $NODE_DIST \
      -a $NODE_ARCH -o $TRIPLEO_ROOT/overcloud-cinder-volume hosts \
      baremetal cinder-volume neutron-openvswitch-agent os-collect-config heat-cfntools pip-cache \
      dhcp-all-interfaces $DIB_COMMON_ELEMENTS $OVERCLOUD_COMPUTE_DIB_EXTRA_ARGS 2>&1 | \
      tee $TRIPLEO_ROOT/dib-overcloud-cinder-volume.log
 load-image overcloud-cinder-volume.qcow2

To be able to deploy object storage node, you need this

$TRIPLEO_ROOT/diskimage-builder/bin/disk-image-create $NODE_DIST \
       -a $NODE_ARCH -o $TRIPLEO_ROOT/overcloud-swift-storage hosts \
       baremetal swift-storage neutron-openvswitch-agent os-collect-config \
       dhcp-all-interfaces $DIB_COMMON_ELEMENTS $OVERCLOUD_COMPUTE_DIB_EXTRA_ARGS 2>&1 | \
       tee $TRIPLEO_ROOT/dib-overcloud-swift-storage.log
 load-image overcloud-swift-storage.qcow2

To list MAC's for virsh listed machines run

virsh list --all
virsh dumpxml baremetal_0 | grep 'mac address' | cut -d\' -f2

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

Install Tuskar

mkdir -p /opt/stack && cd /opt/stack
git clone https://git.openstack.org/openstack/tuskar

Follow the instructions here to complete the install: https://github.com/openstack/tuskar/blob/master/doc/source/install.rst. Make sure that you create the initial data.

To be able to deploy Overcloud via Tuskar, you need to delete the Overcloud created by Devtest first. Go to the Undercloud machine and delete the Overcloud:

ssh heat-admin@192.0.2.3
sudo -i
source stackrc
heat stack-delete overcloud

Devtest will also set up Tuskar endpoints, but pointing to the undercloud machine. You need them point to your machine. This can be done by deleting and readding endpoints, but it's quicker to just modify them in mysql:

ssh heat-admin@192.0.2.3
sudo -i
mysql -u keystone -p keystone
Enter password: unset
update endpoint, service set endpoint.url="http://127.0.0.1:8585/" where service.type="management" and endpoint.service_id=service.id;

Next, you create a plan:

curl -i -X POST -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'User-Agent: python-tuskarclient' -d '{"name": "overcloud", "description": "overcloud"}' http://127.0.0.1:8585/v2/plans

Then you need to check out the role templates:

# use templates from this patch https://review.openstack.org/#/c/123100/
cd /opt/stack
git clone https://git.openstack.org/openstack/tripleo-heat-templates
cd tripleo-heat-templates
git fetch https://review.openstack.org/openstack/tripleo-heat-templates refs/changes/00/123100/4 && git checkout FETCH_HEAD

And load the roles:

cd /opt/stack/tuskar
.tox/py27/bin/tuskar-load-roles --config-file etc/tuskar/tuskar.conf  --master-seed /opt/stack/tripleo-heat-templates/overcloud.yaml --resource-registry /opt/stack/tripleo-heat-templates/overcloud-resource-registry.yaml --role /opt/stack/tripleo-heat-templates/controller.yaml --role /opt/stack/tripleo-heat-templates/compute.yaml

Finally, you need to associate the roles with the plan:

# list the plan to get the ID
curl -i -X GET -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'User-Agent: python-tuskarclient' http://127.0.0.1:8585/v2/plans
# list roles to get their uuids
curl -i -X GET -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'User-Agent: python-tuskarclient' http://127.0.0.1:8585/v2/roles
# add each role to the plan (you'll have to run this once for each role)
curl -i -X POST -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'User-Agent: python-tuskarclient' -d '{"uuid": "<role_uuid>"}' http://127.0.0.1:8585/v2/plans/<plan_uuid>/roles

Add Horizon and Tuskar-UI

Install and configure Horizon and Tuskar-UI using the instructions at: http://tuskar-ui.readthedocs.org/en/latest/install.html. Make sure to clone the horizon and tuskar-ui repositories in /opt/stack.

.Afterwards, 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@192.0.2.3 "sudo -i cat /root/stackrc" > /root/stackrc
sed -i 's/localhost:5000/192.0.2.3:5000/' /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 = "192.0.2.3"/' /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

If you want to develop locally, you need only to mount the remote folder containing the code, in your local file system:

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

Script for installing Tuskar and Tuskar UI

There is a script to automatically do previous two steps: https://gist.github.com/Divius/9525147. It clones to the current directory, uses sudo to do privileged operations, so it can be used by non-root. The only requirement is that stackrc file is in the current directory. Also note that the script is mostly unsupported and can become outdated.
