openstack

OpenStack in a snap that you can run locally on a single machine!

openstack currently provides Nova, Keystone, Glance, Horizon and Neutron OpenStack services.

Installation

openstack is frequently updated to provide the latest stable updates of the most recent OpenStack release. The quickest was to get started is to install directly from the snap store. You can install openstack using:

sudo snap install openstack --classic --edge

Accessing OpenStack

openstack provides a pre-configured OpenStack CLI to access the local OpenStack deployment; its namespaced using the openstack prefix:

openstack.openstack server list

You can setup this command as an alias for openstack if you wish (removing the need for the openstack. prefix):

sudo snap alias openstack.openstack openstack

Alternatively you can access the Horizon OpenStack dashboard on http://127.0.0.1 with the following credentials:

username: admin
password: keystone

Booting and accessing an instance

openstack comes preconfigured with networking and images so you can get starting using OpenStack as soon as openstack is installed; to boot an instance:

openstack.openstack server create --flavor m1.small --nic net-id=test --image cirros my-openstack-server

To access the instance, you'll need to assign it a floating IP address:

ALLOCATED_FIP=`openstack.openstack floating ip create -f value -c floating_ip_address external`
openstack.openstack server add floating ip my-openstack-server $ALLOCATED_FIP

and as you would expect, openstack is just like a full OpenStack Cloud and does not allow ingress access to the instance by default, so next enable SSH and ping access to the instance:

SECGROUP_ID=`openstack.openstack security group list --project admin -f value -c ID`
openstack.openstack security group rule create $SECGROUP_ID --proto tcp --remote-ip 0.0.0.0/0 --dst-port 22
openstack.openstack security group rule create $SECGROUP_ID --proto icmp --remote-ip 0.0.0.0/0

once this is complete you should be able to SSH to the instance:

ssh cirros@$ALLOCATED_FIP

Happy openstacking!

Stopping and starting openstack

You may wish to temporarily shutdown openstack when not in use without un-installing it.

openstack can be shutdown using:

sudo snap disable openstack

and re-enabled latest using:

sudo snap enable openstack
