7 Chapt er 1. How can I administ er an O penst ack cloud? Chapter 1. How can I administer an OpenStack cloud? As an OpenStack cloud administrative user, you can manage tenants, known as projects, users, services, images, flavors, and quotas. The examples in this guide show you how to perform tasks by using the following methods: OpenStack dashboard. Use this web-based graphical interface, code named " horizon", to view, create, and manage resources and services. OpenStack command-line clients. Each core OpenStack project has a command-line client that you can use to run simple commands to view, create, and manage resources and services in a cloud and automate tasks by using scripts. You can modify these examples for your specific use cases. In addition to these ways of interacting with a cloud, you can access the OpenStack APIs directly or indirectly through curl commands or open SD Ks. You can automate access or build tools to manage resources and services by using the native OpenStack APIs or the EC2 compatibility API. To use the OpenStack APIs, it helps to be familiar with HTTP/1.1, RESTful web services, the OpenStack services, and JSON or XML data serialization formats. 3

8 Red Hat Ent erprise Linux O penst ack Plat form 5 Administ rat ion User G uide Chapter 2. Dashboard As a cloud administrative user, the OpenStack dashboard lets you create and manage projects, users, images, and flavors. You can also set quotas and create and manage services. For information about using the dashboard to perform end user tasks, see the End User Guide at US/Red_Hat_Enterprise_Linux_OpenStack_Platform/. 1. Log in t o t he dashboard The dashboard is available on the node with the no va-d ashbo ard server role. 1. Ask the cloud operator for the host name or public IP address from which you can access the dashboard, and for your user name and password. 2. Open a web browser that has JavaScript and cookies enabled. Note To use the Virtual Network Computing (VNC) client for the dashboard, your browser must support HTML5 Canvas and HTML5 WebSockets. The VNC client is based on novnc. For details, see novnc: HTML5 VNC Client. For a list of supported browsers, see Browser support. 3. In the address bar, enter the host name or IP address for the dashboard. Note If a certificate warning appears when you try to access the URL for the first time, a self-signed certificate is in use, which is not considered trustworthy by default. Verify the certificate or add an exception in the browser to bypass the warning. 4. On the Lo g In page, enter your user name and password, and click Si g n In. The top of the window displays your user name. You can also access Setti ng s or sign out of the dashboard. The visible tabs and functions in the dashboard depend on the access permissions, or roles, of the user you are logged in as. If you are logged in as an end user, the Project tab is displayed. If you are logged in as an administrator, the Project tab and Admin tab are displayed OpenSt ack dashboard- Project t ab 4

Within a project, a user creates and manages instances. From the P ro ject tab, you can view and manage the resources in a selected project, including instances and images. You select the project from the C urrent P ro ject Project_Name list at the top of the tab. Figure 2.1. Project tab From the P ro ject tab, you can access the following tabs: C o mpute tab O vervi ew View reports for the project.

Id enti ty P anel tab P ro jects View, create, assign users to, remove users from, and delete projects. Users View, create, enable, disable, and delete users. 2. Manage project s and users As a cloud administrator, you manage both projects and users. Projects are organizational units in the cloud to which you can assign users. Projects are also known as tenants or accounts.you can manage projects and users independently from each other. Users are members of one or more projects. During cloud set up, the operator defines at least one project, user, and role. The operator links the role to the user and the user to the project. Roles define the actions that users can perform. As an administrator, you can create additional projects and users as needed. Learn how to add, update, and delete projects and users, assign users to one or more projects, and change or remove the assignment. To enable or temporarily disable a project or user, update that project or user. When you create a user account, you must assign the account to a primary project. Optionally, you can assign the account to additional projects. Before you can delete a user account, you must remove the user account from its primary project Consequences of disabling project s and users When you disable a project, it has the following consequences: 9

Creat e and manage host aggregat es Host aggregates enable administrative users to assign key-value pairs to groups of machines. Each node can have multiple aggregates and each aggregate can have multiple key-value pairs. You can assign the same key-value pair to multiple aggregates. The scheduler uses this information to make scheduling decisions. For more information, see the Configuration Reference Guide at US/Red_Hat_Enterprise_Linux_OpenStack_Platform/. Procedure 2.1.

In a production deployment with multiple servers, you could have multiple host aggregates associated with different availability zones, based on location and other factors. 9. Launch and manage st acks The Orchestration service provides a template-based orchestration engine for the OpenStack cloud, which can be used to create and manage cloud infrastructure resources such as storage, networking, instances, and applications as a repeatable running environment. Templates are used to create stacks, which are collections of resources. For example, a stack might include instances, floating IPs, volumes, security groups, or users. The Orchestration service offers access to all OpenStack core services via a single modular template, with additional orchestration capabilities such as auto-scaling and basic high availability. For information about: Administrative tasks on the command line, see Section 9.4, Launch and manage stacks. Note There are no administration-specific tasks that can be done through the dashboard. The basic creation and deletion of Orchestration stacks, see the End User Guide at US/Red_Hat_Enterprise_Linux_OpenStack_Platform/. 26

31 Chapt er 3. O penst ack command- line client s Chapter 3. OpenStack command-line clients 1. Overview You can use the OpenStack command-line clients to run simple commands that make API calls. You can run these commands from the command line or in scripts to automate tasks. If you provide OpenStack credentials, you can run these commands on any computer. Internally, each client command runs curl commands that embed API requests. The OpenStack APIs are RESTful APIs that use the HTTP protocol, including methods, URIs, media types, and response codes. These open-source Python clients run on Linux systems and are easy to learn and use. Each OpenStack service has its own command-line client. On some client commands, you can specify a d ebug parameter to show the underlying API request for the command. This is a good way to become familiar with the OpenStack API calls. The following table lists the command-line client for each OpenStack service with its package name and description. Table 3.1.

For more information on installation instructions and the OpenStack RC file, see the End User Guide at US/Red_Hat_Enterprise_Linux_OpenStack_Platform/. 2. Discover t he version number for a client Run the following command to discover the version number for a client: $ PROJECT --version For example, to see the version number for the no va client, run the following command: $ nova --version The version number ( in the example) is returned Get help for client commands To get usage information, including a list of commands with descriptions, for a client, run the following command: $ CLIENT_NAME help For example, to get help information for the swift client, run the following command: $ swift help Note D epending on your credentials, you might not have permission to use every command. After the hel p command, you can enter a command name to get help for that command, as follows: $ CLIENT_NAME help COMMAND_NAME For example, to get help for the glance i mag e-sho w command, enter the following command: $ glance help image-show The command returns a description of the command and its positional and optional arguments: usage: glance image-show [--human-readable] <IMAGE> Describe a specific image. 28

Manage project s, users, and roles As a cloud administrator, you manage projects, users, and roles. Projects are organizational units in the cloud to which you can assign users. Projects are also known as tenants or accounts. Users can be members of one or more projects. Roles define which actions users can perform. You assign roles to user-project pairs. You can define actions for OpenStack service roles in the /etc/project/po l i cy. jso n files. For example, define actions for Compute service roles in the /etc/no va/po l i cy. jso n file. You can manage projects, users, and roles independently from each other. During cloud set up, the operator defines at least one project, user, and role. Learn how to add, update, and delete projects and users, assign users to one or more projects, and change or remove the assignment. To enable or temporarily disable a project or user, you update that project or user. You can also change quotas at the project level. Before you can delete a user account, you must remove the user account from its primary project. Before you can run keystone client commands, you must download and source an OpenStack RC file. See the End User Guide at US/Red_Hat_Enterprise_Linux_OpenStack_Platform/ Services To look at your service catalog, use these keystone client commands servi ce-create Keyword arguments: Name Type D escription Example: $ keystone service-create \ --name=nova \ --type=compute \ --description="nova Compute Service" 29
