Developer Quick-Start
|
|
=====================
|
|
|
|
This is a quick walkthrough to get you started developing code for Zun.
|
|
This assumes you are already familiar with submitting code reviews to
|
|
an OpenStack project.
|
|
|
|

|
Exercising the Services Using Devstack
|
|
======================================
|
|
|
|
This session has been tested on Ubuntu 16.04 (Xenial) only.
|
|
|
|
Clone devstack::
|
|
|
|
# Create a root directory for devstack if needed
|
|
sudo mkdir -p /opt/stack
|
|
sudo chown $USER /opt/stack
|
|
|
|
git clone https://git.openstack.org/openstack-dev/devstack /opt/stack/devstack
|
|
|
|
We will run devstack with minimal local.conf settings required to enable
|
|
required OpenStack services::
|
|
|
|
$ cat > /opt/stack/devstack/local.conf << END
|
|
[[local|localrc]]
|
|
HOST_IP=$(ip addr | grep 'state UP' -A2 | tail -n1 | awk '{print $2}' | cut -f1 -d'/')
|
|
DATABASE_PASSWORD=password
|
|
RABBIT_PASSWORD=password
|
|
SERVICE_TOKEN=password
|
|
SERVICE_PASSWORD=password
|
|
ADMIN_PASSWORD=password
|
|
enable_plugin zun https://git.openstack.org/openstack/zun
|
|
enable_plugin kuryr-libnetwork https://git.openstack.org/openstack/kuryr-libnetwork
|
|
|
|
# Optional: uncomment to enable the Zun UI plugin in Horizon
|
|
# enable_plugin zun-ui https://git.openstack.org/openstack/zun-ui
|
|
END
|
|
|
|
By default, devstack will enable docker driver in Zun. Alternatively, you can
|
|
enable nova-docker driver instead. If nova-docker driver is enabled, zun will
|
|
use Nova to manage `container sandboxes <https://github.com/openstack/zun/blob/master/specs/container-sandbox.rst>`_.
|
|
Simply speaking, you should choose nova-docker driver if you want to get
|
|
containers with networking provided by Neutron. Otherwise, choose docker
|
|
driver::
|
|
|
|
$ cat >> /opt/stack/devstack/local.conf << END
|
|
ZUN_DRIVER=nova-docker
|
|
IP_VERSION=4
|
|
disable_service n-net
|
|
enable_service q-svc
|
|
enable_service q-agt
|
|
enable_service q-dhcp
|
|
enable_service q-l3
|
|
enable_service q-meta
|
|
enable_service neutron
|
|
END
|
|
|
|
More devstack configuration information can be found at
|
|
https://docs.openstack.org/developer/devstack/configuration.html
|
|
|
|
More neutron configuration information can be found at
|
|
https://docs.openstack.org/developer/devstack/guides/neutron.html
|
|
|
|
Run devstack::
|
|
|
|
cd /opt/stack/devstack
|
|
./stack.sh
|
|
|
|
Prepare your session to be able to use the various openstack clients including
|
|
nova, neutron, and glance. Create a new shell, and source the devstack openrc
|
|
script::
|
|
|
|
source /opt/stack/devstack/openrc admin admin
|
|
|
|
Using the service
|
|
=================
|
|
|
|
We will create and run a container that pings the address 8.8.8.8 four times::
|
|
|
|
$ zun run --name test cirros ping -c 4 8.8.8.8
|
|
|
|
You should see a similar output to::
|
|
|
|
$ zun list
|
|
+--------------------------------------+------+--------+---------+------------+------------+-------+
|
|
| uuid | name | image | status | task_state | addresses | ports |

|

|
|

|
|
|
|
$ zun logs test
|
