Managing Images for the Image
Service
2
In the OpenStack context, an image is a file that contains a virtual disk from which you can install an operating system on a VM. You create an instance in your OpenStack cloud by using one of the images available. The VMware Integrated OpenStack Image Service component natively supports images that are packaged in the ISO, OVA, and VMDK formats.
If you have existing images in vSphere that you want to use in OpenStack, you can export them in one of the supported formats and upload them to the Image Service. If you obtain an image that is in an unsupported format, you can convert it as part of the import process. Unsupported formats are RAW, QCOW2, VDI, and
VHD.
This chapter includes the following topics: n

Configuring Access and Security for
Instances
3
Before you start instances, configure access and security settings. For example, SSH access and ICMP access are not enabled by default.
Security groups
Enable users to ping and use SSH to connect to the instance. Security groups are sets of IP filter rules that define networking access and are applied to all instances in a project.
Key pairs
SSH credentials that are injected into an instance when it starts. To use key pair injection, the image that the instance is based on must contain the cloudinit package. Each project must have at least one key pair. If you generated a key pair with an external tool, you can import it into OpenStack. You can use the key pair for multiple instances that belong to a project.
Floating IPs
When you create an instance in OpenStack, it is assigned a fixed IP address in the network. This IP address is permanently associated with the instance until the instance is terminated. You can also attach to an instance a floating
IP address whose association can be modified.
This chapter includes the following topics: n
“Working with Security Groups,” on page 13
n n
“Working with Key Pairs,” on page 16
“Allocate a Floating IP to an Instance,” on page 17
Working with Security Groups
A security group is a set of IP filter rules that define networking access and that you can apply to all instances in a project. Group rules are project-specific. Project members can edit the default rules for their group and add new rule sets.
You can use security groups to apply IP rules by creating a new security group with the desired rules or by modifying the rules set in the default security group.
Note A security group can apply either rules or a security policy, but not both.
Important For deployments with VMware NSX-T, the maximum number of security groups per port is 9.
VMware, Inc. 13
VMware Integrated OpenStack User Guide
14
About the Default Security Group
Each project in VMware Integrated OpenStack has a default security group that is applied to an instance unless another security group is defined and specified. Unless it is modified, the default security group denies all incoming traffic to your instance and permits only outgoing traffic. A common example is to edit the default security group to permit SSH access and ICMP access, so that users can log in to and ping instances.
Create a Security Group
Security groups are sets of IP filter rules that define networking access and are applied to all instances within a project. You can either modify the rules in the default security group or create a security group with custom rules.
To modify an existing rule for a security group, see
“Modify the Rules for an Existing Security Group,” on page 14

The Nova scheduler provides filters that you can use to ensure that OpenStack instances are automatically placed on the same host (affinity) or separate hosts (anti-affinity).
You apply the affinity or anti-affinity filter as a policy to a server group. All instances that are members of the same group are subject to the same filters. When you create an OpenStack instance, you can specify the server group to which the instance will belong and therefore what filter will be applied.
You can perform this configuration using either the OpenStack CLI or ServerGroup API. You cannot perform this configuration in the VMware Integrated OpenStack Horizon dashboard.
24 VMware, Inc.
Chapter 5 Working with Instances in OpenStack
This approach to placing OpenStack instances is tenant-based. Affinity and anti-affinity determine the relationship among instances in the same server group, but they cannot determine the hosts on which the instances are placed in vCenter. For an administrator-based approach that provides greater control, see
VMware Integrated OpenStack Administrator Guide.
Create Instances with an Affinity or Anti-Affinity Policy by Using the CLI
You can place instances using affinity or anti-affinity by creating a server group in OpenStack and applying desired filter as a group policy. All instances that are members of the server group will be subject to the affinity or anti-affinity policy. You can perform this configuration using the CLI.
Prerequisites
n
Verify with the cloud administrator that the intended filter configuration does not conflict with any administrative configuration, such as DRS rules that manage instance placement on hosts.
n n n
Verify that you are running VMware Integrated OpenStack version 2.0.x or later.
Verify that VMware Integrated OpenStack is running.
Verify that you are using a Python nova-client version 2.17.0.6 or later as required for the ServerGroup
API. Go to http://docs.openstack.org/user-guide/common/cli_install_openstack_command_line_clients.html
.
Procedure
1 Using SSH, log in to the nova-client.
2 (Optional) Obtain the ID of the image you will use to create the instance.
You can use the nova image-list
command to view the list of available images and their ID values.
3 (Optional) Obtain the ID of the flavor you will use to define the instance .
You can use the nova flavor-list
command to view the list of flavor definitions and their ID values.
4 Create a new server group with the intended policy.
a Create a server group with the affinity policy: nova server-group-create GROUP_NAME affinity b Create a server group with the anti-affinity policy: nova server-group-create GROUP_NAME anti-affinity
In both case, the CLI returns the auto-generated server group UUID, name, and policy.
5 Launch a new instance, using the
--image
,
--flavor
, and
--hint
flags to apply the server group affinity policy .
nova boot --image IMAGE_ID --flavor FLAVOR_ID --hint group=SERVER_GROUP_UUID INSTANCE_NAME
6 (Optional) Ask your cloud administrator to confirm that the new rule and the server group instances appear and are running correctly in the VMware Integrated OpenStack deployment in vCenter Server.
The details appear in the Manage > Settings > VM/Host Rules page for the Compute cluster.

Working with Orchestration and
Stacks
7
You can use the OpenStack Orchestration service to orchestrate multiple composite cloud applications. It supports the native OpenStack Heat Orchestration Template (HOT) format through a REST API, and the
Amazon Web Services (AWS) CloudFormation template format through a Query API that is compatible with CloudFormation.
You use templates to create stacks. A stack configures the automated creation of most OpenStack resource types, including instances, floating IP addresses, volumes, security groups, and users.
With orchestration templates, application developers can define the parameters for automating the deployment of infrastructure, services, and applications. Templates are static files that you can use directly for creating a stack.
You can also create a stack that combines a template with an environment file. An environment file supplies a unique set of values to the parameters defined by the template. By using environment files with templates, you can create many unique stacks from a single template.
For information about how to create template and environment files, see the OpenStack documentation at http://docs.openstack.org/developer/heat/template_guide/index.html.
