OpenStack in a snap!

Pete Vander Giessen c3ba4ee501 Delay creating external bridge until we are initializing Previously, the snap set up a bridge using the default 10.20.20.0/24 network upon install. If there was a good reason not to use this network (e.g., it already exists and is being used for another purpose), MicroStack, and the host machine, could wind up in a broken state. This PR delays setting up the bridge until after we have given an operator a chance to override the default settings. This has been manually tested. To test, do the following: 1) Checkout the code, and run tox -e build 2) Run tools/make-a-microstack.sh 3) snapctl set config.network.ext-cidr and config.network.ext-gateway 4) Run microstack_init 5) Exit the snap shell and run microstack.launch Change-Id: I9e268495f313b29d9781d80a2468fc0a1a450aa0 Closes-Bug: https://bugs.launchpad.net/microstack/+bug/1851521		2019-11-12 23:19:51 +00:00

README.md

MicroStack

MicroStack is a single-machine, snap-deployed OpenStack cloud.

Common purposes include:

Development and testing of OpenStack workloads
Continuous integration (CI)
IoT and appliances
Edge clouds (experimental)
Introducing new users to OpenStack

Currently provided OpenStack services are: Nova, Keystone, Glance, Horizon, and Neutron.

MicroStack is frequently updated to provide the latest stable updates of the most recent OpenStack release.

Requirements: You will need at least 2 CPUs, 8 GiB of memory, and 100 GiB of disk space.

See the full MicroStack documentation.

Installation

At this time you can install from the --beta or --edge snap channels:

sudo snap install microstack --classic --beta

Initialisation

Initialisation will set up databases, networks, flavors, an SSH keypair, a CirrOS image, and open ICMP/SSH security groups:

sudo microstack.init --auto

OpenStack client

The OpenStack client is bundled as microstack.openstack. For example:

microstack.openstack network list
microstack.openstack flavor list
microstack.openstack keypair list
microstack.openstack image list
microstack.openstack security group rule list

Creating an instance

To create an instance (called "awesome") based on the CirrOS image:

microstack.launch cirros --name awesome

SSH to an instance

The launch output will show you how to connect to the instance. For the CirrOS image, the user account is 'cirros'.

ssh -i ~/.ssh/id_microstack cirros@<ip-address>

Horizon

The launch output will also provide information for the Horizon dashboard. Its credentials are:

username: admin
password: keystone

Customising and contributing

To customise services and settings, look in the .d directories under /var/snap/microstack/common/etc. You can add services with your package manager, or take a look at CONTRIBUTING.md and make a code based argument for adding a service to the default list.

Reporting a bug

Please report bugs to the MicroStack project on Launchpad.
