Chapter 9. Accessing an overcloud deployed with director Operator After you deploy the overcloud with director Operator (OSPdO), you can access it and run commands with the openstack client tool. The main access point for the overcloud is through the OpenStackClient pod that OSPdO deploys as a part of the OpenStackControlPlane resource that you created. 9.1. Accessing the OpenStackClient pod The OpenStackClient pod is the main access point to run commands against the overcloud. This pod contains the client tools and authentication details that you require to perform actions on your overcloud. To access the pod from your workstation, you must use the oc command on your workstation to connect to the remote shell for the pod. Note When you access an overcloud that you deploy without director Operator (OSPdO), you usually run the source ~/overcloudrc command to set environment variables to access the overcloud. You do not require this step with an overcloud that you deploy with OSPdO. Procedure Access the remote shell for openstackclient : Change to the cloud-admin home directory: Run your openstack commands. For example, you can create a default network with the following command: Additional resources Creating and managing instances Configuring Red Hat OpenStack Platform networking 9.2. Accessing the overcloud dashboard You access the dashboard of an overcloud that you deploy with director Operator (OSPdO) by using the same method as a standard overcloud: access the virtual IP address reserved by the control plane by using a web browser. Procedure Optional: To login as the admin user, obtain the admin password from the AdminPassword parameter in the tripleo-passwords secret: Retrieve the IP address reserved for the control plane from your OpenStackNetConfig CR: Open a web browser. Enter the IP address for the control plane in the URL field. Log in to the dashboard with your username and password.

Commands:
oc rsh -n openstack openstackclient
cd /home/cloud-admin
openstack network create default

Appendix A. Managing certificates A.1. Installing certificate authority certificates SSL/TLS authentication relies on digital certificates issued by trusted Certificate Authorities (CAs). When an SSL/TLS connection is established by a client, the AMQP peer sends a server certificate to the client. This server certificate must be signed by one of the CAs in the client's Trusted Root Certification Authorities certificate store. If the user is creating self-signed certificates for use by Red Hat AMQ Broker, then the user must create a CA to sign the certificates. Then the user can enable the client SSL/TLS handshake by installing the self-signed CA file ca.crt . From an administrator command prompt, run the MMC Certificate Manager plugin, certmgr.msc . Expand the Trusted Root Certification Authorities folder on the left to expose Certificates . Right-click Certificates and select All Tasks and then Import . Click . Browse to select file ca.crt . Click . Select Place all certificates in the following store . Select certificate store Trusted Root Certification Authorities . Click . Click Finish . For more information about installing certificates, see Managing Microsoft Certificate Services and SSL . A.2. Installing client certificates In order to use SSL/TLS and client certficates, the certificates with the client's private keys must be imported into the proper certificate store on the client system. From an administrator command prompt, run the MMC Certificate Manager plugin, certmgr.msc . Expand the Personal folder on the left to expose Certificates . Right-click Certificates and select All Tasks and then Import . Click . Click Browse . In the file type pulldown, select Personal Information Exchange (\.pfx;*.p12) . Select file client.p12 and click Open . Click . Enter the password for the private key password field. Accept the default import options. Click . Select Place all certificates in the following store . Select certificate store Personal . Click . Click Finish . A.3. Hello World using client certificates Before a client will return a certificate to the broker, the AMQ .NET library must be told which certificates to use. The client certificate file client.crt is added to the list of certificates to be used during SChannel connection startup. In this example, certfile is the full path to the client.p12 certificate installed in the Personal certificate store. A complete example is found in HelloWorld-client-certs.cs . This source file and the supporting project files are available in the SDK.

Commands:
factory.SSL.ClientCertificates.Add( X509Certificate.CreateFromCertFile(certfile) );
2.4. Cluster Considerations When determining the number of nodes that your system will contain, note that there is a trade-off between high availability and performance. With a larger number of nodes, it becomes increasingly difficult to make workloads scale. For that reason, Red Hat does not support using GFS2 for cluster file system deployments greater than 16 nodes. Deploying a cluster file system is not a "drop in" replacement for a single node deployment. We recommend that you allow a period of around 8-12 weeks of testing on new installations in order to test the system and ensure that it is working at the required performance level. During this period any performance or functional issues can be worked out and any queries should be directed to the Red Hat support team. We recommend that customers considering deploying clusters have their configurations reviewed by Red Hat support before deployment to avoid any possible support issues later on.

Chapter 1. The Ceph Object Gateway Ceph Object Gateway, also known as RADOS Gateway (RGW), is an object storage interface built on top of the librados library to provide applications with a RESTful gateway to Ceph storage clusters. Ceph Object Gateway supports three interfaces: S3-compatibility: Provides object storage functionality with an interface that is compatible with a large subset of the Amazon S3 RESTful API. You can run S3 select to accelerate throughput. Users can run S3 select queries directly without a mediator. There are two S3 select workflows, one for CSV and one for Apache Parquet (Parquet), that provide S3 select operations with CSV and Parquet objects. For more details about these S3 select operations, see section S3 select operations in the Red Hat Ceph Storage Developer Guide . Swift-compatibility: Provides object storage functionality with an interface that is compatible with a large subset of the OpenStack Swift API. The Ceph Object Gateway is a service interacting with a Ceph storage cluster. Since it provides interfaces compatible with OpenStack Swift and Amazon S3, the Ceph Object Gateway has its own user management system. Ceph Object Gateway can store data in the same Ceph storage cluster used to store data from Ceph block device clients; however, it would involve separate pools and likely a different CRUSH hierarchy. The S3 and Swift APIs share a common namespace, so you can write data with one API and retrieve it with the other. Administrative API: Provides an administrative interface for managing the Ceph Object Gateways. Administrative API requests are done on a URI that starts with the admin resource end point. Authorization for the administrative API mimics the S3 authorization convention. Some operations require the user to have special administrative capabilities. The response type can be either XML or JSON by specifying the format option in the request, but defaults to the JSON format. Additional Resources See the Red Hat Ceph Storage Developer Guide for details on the available APIs in Red Hat Ceph Storage.

Preface Important The following proof of concept deployment method is unsupported for production purposes. This deployment type uses local storage. Local storage is not guaranteed to provide the required read-after-write consistency and data integrity guarantees during parallel access that a storage registry like Red Hat Quay requires. Do not use this deployment type for production purposes. Use it for testing purposes only. Red Hat Quay is an enterprise-quality registry for building, securing and serving container images. The documents in this section detail how to deploy Red Hat Quay for proof of concept , or non-production, purposes. The primary objectives of this document includes the following: How to deploy Red Hat Quay for basic non-production purposes. Asses Red Hat Quay's container image management, including how to push, pull, tag, and organize images. Explore availability and scalability. How to deploy an advanced Red Hat Quay proof of concept deployment using SSL/TLS certificates. Beyond the primary objectives of this document, a proof of concept deployment can be used to test various features offered by Red Hat Quay, such as establishing superusers, setting repository quota limitations, enabling Splunk for action log storage, enabling Clair for vulnerability reporting, and more. See the " steps" section for a list of some of the features available after you have followed this guide. This proof of concept deployment procedure can be followed on a single machine, either physical or virtual.

Chapter 8. Viewing and managing JMX domains and MBeans Java Management Extensions (JMX) is a Java technology that allows you to manage resources (services, devices, and applications) dynamically at runtime. The resources are represented by objects called MBeans (for Managed Bean). You can manage and monitor resources as soon as they are created, implemented, or installed. With the JMX plugin on the Fuse Console, you can view and manage JMX domains and MBeans. You can view MBean attributes, run commands, and create charts that show statistics for the MBeans. The JMX tab provides a tree view of the active JMX domains and MBeans organized in folders. You can view details and execute commands on the MBeans. Procedure To view and edit MBean attributes: In the tree view, select an MBean. Click the Attributes tab. Click an attribute to see its details. To perform operations: In the tree view, select an MBean. Click the Operations tab, expand one of the listed operations. Click Execute to run the operation. To view charts: In the tree view, select an item. Click the Chart tab.
