In addition to being a useful sandbox for developers using the OpenStack APIs and others interested in seeing what OpenStack is all about, TryStack.org is also a very useful testbed for work that the OpenStack community is doing to automate the deployment and administration OpenStack environments.
The tools that we are using in the community can look complicated if you arenot familiar with them. To help you practice before you use them in action weare providing sandbox environments for you where you can practice all the stepswe describe in this guide.
Even if is the sandbox is not covering all OpenStack functionalities, it is possible to have a good idea of the solution: you can create projects, launch instances, create images and snaphots, create and attach volume, etc. For example, I can launch 3 instances of the preloaded cirros Linux image.
There are a number of ways to find, and authenticate to, OpenStack APIs. So farboth the openstack command you used in Stage 1 and the Ansible ad-hoc commandyou just executed using the os_auth module found the necessary meta data viaa clouds.yaml file. In this particular case here: /.config/openstack/clouds.yaml.
Whilst Ansible itself can use clouds.yaml via the openstacksdk packageyou pip installed earlier AgnosticD actually uses a different way ofauthenticating to OpenStack via vars expressed in YAML. Fortunately your environment has been, largely,pre-configured via a file located at /.secrets.yml
For instance, you can use the following command, which includes some extra parameters, to add a VIM target with VIO (e.g. site name: openstack-site-vio4, IP address: 10.10.10.12, VIM tenant: admin, user: admin, password: passwd)
Sometimes, casual testers of OSM may not have a fully fledged VIM at hand, either on premises or in a public cloud. In those cases, it is also possible using a VIM sandbox which, although limited and hence not appropriate for production services, it can be an option good enough for beginners.
MicroStack is a single-machine OpenStack cloud sandbox, developed by Canonical, and deployable with a single snap packages. Currently provided OpenStack services are: Nova, Keystone, Glance, Horizon, and Neutron, which should suffice for any basic OSM testing.
REASON: I must point out that the quickest way to dive into Openstack is to head over to The Openstack Sandbox Project. They have done an excellent job at making sure anyone can test and learn openstack. You will need a Facebook account, as the authentication piece is handle by the Facebook Login API. Additionally, some of the features are not enabled (like Heat orchestration), but some really cool features are (like Trove). Give them a try first, and then when you've decided you really like it, and want to use it more come back to this handy walkthrough!
This is a hands-on tutorial. To get the most out of it, you will need OpenvSwitch binaries. You do not, on the other hand, need any physical networkinghardware or even supervisor privilege on your system. Instead, we will use ascript called ovs-sandbox, which accompanies the tutorial, that constructsa software simulated network environment based on Open vSwitch.
If you have not installed Open vSwitch (and you do not want to install it),then you can build Open vSwitch according to the instructions inOpen vSwitch on Linux, FreeBSD and NetBSD, without installing it. Then run./ovs-sandbox -b DIRECTORY from this directory, substituting the OpenvSwitch build directory for DIRECTORY.
ovs-sandbox also has a -g option for launching ovs-vswitchd under GDB.This option can be handy for setting break points before ovs-vswitchd runs, orfor catching early segfaults. Similarly, a -d option can be used to runovsdb-server under GDB. Both options can be specified at the same time.
Once you have ovs-sandbox running with OVN enabled, you can start using OVNutilities to create resources in OVN. As an example, we will create anenvironment that has two logical switches connected by a logical router.
As intended for a sandbox environment, we use CloudNativeLab to provide a place where anyone can test and experiment. The same applies to us while maintaining and updating the system. Occasionally, some downtimes can be expected. We will try to bring the environment back online as soon as possible.
CloudShell creates a saved sandbox. When the saving process completes, the saved sandbox is displayed in the Saved Sandboxes dashboard and the original sandbox is available for use. Note that only admins and permitted users of the saved sandbox can see and restore it. They can restore it and then invite permitted users to the new restored sandbox. For details about what information is saved, see the section below.
If the sandbox teardown starts before the saving process completes, the saving process will be canceled. To avoid such a scenario, ensure that the sandbox duration is set so that you have enough time to save the sandbox. If you do not, extend the sandbox duration. See Extend and End Sandboxes for more information.
Once the saving action completes successfully, a saved sandbox is created and the sandbox returns to the active state. You can then continue working in the sandbox and save additional instances, if required.
Currently, CloudShell supports saving sandboxes that contain vCenter/OpenStack-based Apps, inventory resources and CloudShell services. Apps of other cloud providers are not supported and therefore, you cannot save a sandbox which contains these elements.
Each deployed App in the original sandbox represents a running VM, which was deployed by the App in the sandbox. When saving, CloudShell clones this VM, and creates a snapshot of the cloned VM on the vCenter/OpenStack server. Optionally, you can configure CloudShell to power off the original VM for the duration of the saving process using the Behavior During Save attribute, as explained in vCenter/OpenStack advanced saving configurations.
In the vCenter server, cloned VMs reside in a folder named as the saved sandbox ID. This folder is located within the Saved Sandboxes folder, defined in the VM Location attribute on the vCenter cloud provider resource. For example:
The route's endpoint information is copied, not the route solution. The save procedure also supports scenarios where connections are created after the sandbox was created and therefore do not exist in the blueprint.
If the VLAN service in the originalting sandbox is a VLAN Auto service, it is copied without the allocated VLAN. Therefore, in this case, the restored saved sandbox might get a different VLAN than the one assigned in the original sandbox.
If you just want to give OpenStack a try, one good resource for spinning the wheels without committing any physical resources is TryStack. TryStack lets you test your applications in a sandbox environment to better understand how OpenStack works and whether it is the right solution for you.
More images can be found in the MUNI-KYPO-IMAGES GitLab group. These images, each stored in its own repository, were created specifically for the needs of KYPO-CRP and their use is strongly recommended. Once an image is uploaded to the OpenStack project, it can be used in the topology.yml file of the sandbox definition.
From now on, new patches and recheck comments on the openstack-dev/sandboxproject will fire the dsvm-tempest-full Jenkins job on your devstack slave node. If your test run was successful, you will see something like this in your Jenkins console for the job run:
Creating a sandbox environment using VirtualBox (or VMware Fusion) and Vagrant allows us to discover and experiment with the OpenStack services. VirtualBox gives us the ability to spin up virtual machines and networks without affecting the rest of our working environment, and is freely available at for Windows, Mac OS X, and Linux. Vagrant allows us to automate this task, meaning we can spend less time creating our test environments and more time using OpenStack. This test environment can then be used for the rest of the OpenStack Cloud Computing Cookbook.
To create our sandbox environment within VirtualBox we will use Vagrant to define a number of virtual machines that allows us to run all of the OpenStack services used in the OpenStack Cloud Computing Cookbook.
These virtual machines will be configured with at an appropriate amount of RAM, CPU and Disk, and have a total of four network interfaces. Vagrant automatically setups an interface on our virtual machine that will NAT (Network Address Translate) traffic out, allowing our virtual machine to connect to the network outside of VirtualBox to download packages. This NAT interface is not mentioned in our Vagrantfile but will be visible on our virtual machine as eth0. A Vagrantfile, which is found in the working directory of our virtual machine sandbox environment, is a simple file that describes our virtual machines and how VirtualBox will create them. We configure our first interface for use in our OpenStack environment, which will be the host network interface of our OpenStack virtual machines (the interface a client will connect to Horizon, or use the API), a second interface will be for our private network that OpenStack Compute uses for internal communication between different OpenStack Compute hosts and a third which will be used when we look at Neutron networking as an external provider network. When these virtual machines become available after starting them up, you will see the four interfaces that are explained below:
TryStack is a cloud-based OpenStack sandbox created by Red Hat and the RDO community. The TryStack organization hosts a cluster of hardware running OpenStack that you may access to test OpenStack. It is intended to support developers but people who just want to try OpenStack may use it, too.
