Configure an OpenStack Region

To configure a region you added to your OpenStack cloud, follow this procedure.

  1. Navigate to Clouds page: Admin > Clouds. Find the your OpenStack cloud from the cloud list on the left half of the screen and click its Configure Cloud link. This displays the Regions tab for this cloud as shown in the figure below with the Cloud Settings section displayed first.



    After you have added multiple regions to your OpenStack cloud, the Regions tab will show multiple individual region tabs on the left side of the screen. Click the tab of the region you want to configure.
  2. Click the Edit Cloud Settings link in the upper right of the Cloud Settings section. This opens the Configure Cloud Settings dialog box. The Cloud Settings section contains fields that are unique to OpenStack and settings that are common to all cloud providers. Adjust these field values per the instructions in the following tables.

    OpenStack Specific Cloud Settings

    FieldUsage
    Region

    This is a read-only field based on the region name you entered when you created this region.

    OpenStack Keystone API version

    The default value is V2. Use the dropdown menu to change this to V3 if your version of OpenStack supports the V3 API.

    OpenStack Keystone Authentication EndpointEnter the URL of your OpenStack API endpoint.
    Additional Ports for OpenStack endpointsThese are pre-populated with the standard ports for communication between the OpenStack API and Workload Manager. Only change these values if you have a non-standard network configuration for OpenStack.
    Use Config DriveThis is unchecked by default. Check this box if your deployments need to use configdrive.
    Nodes Per Batch

    This is the maximum number of VMs that can be launched simultaneously per application deployment. If left blank, the default value of 1 is applied. A value of 0 or 1 both mean only one VM will be launched at a time.

    Bootable Volume Mapping RequiredDefault means no mapping. You only need to change this field if OpenStack is configured along with a third-party infrastructure that is not visible to Workload Manager.


    Cloud Agnostic Cloud Settings

    Field

    Usage

    Exclude these special characters for Windows password

    When the Workload Manager agent is installed on a Windows worker VM, a special user account, called cliqruser, is created to support RDP sessions that may be initiated by the user through the Workload Manager UI. A Workload Manager process running on the CloudCenter Suite cluster creates a random password and passes it to the agent for creating the cliqruser account. Because some Windows deployments may restrict using certain characters for Windows passwords, this field is provided to tell the Workload Manager to exclude these special characters in the generation of the password for the cliqruser account.

    Agent Bundle URL

    If you plan to use a local repository to host the bundle store, you need to enter the URL of the local bundle store here. Otherwise, leave blank.

    Agent Custom Repository

    If you plan to use a local repository to host the package store, you need to enter the URL of the local package store here. Otherwise, leave blank.

    HTTP/HTTPS proxy fields (host, username, password)

    If you require VMs in your region to access public addresses through a web proxy, enter the URL and credentials of the HTTP and HTTPS proxy servers in these fields.

    No Proxy Hosts

    If you have specified an HTTP or HTTP proxy using the above fields, you can specify that managed VMs in the region should bypass the proxy and connect directly to certain hosts. Use this field to create a comma-separated list of IP addresses or URLs that should be accessed directly. This field is ignored if an HTTP or HTTPS proxy is not specified.

    Important information on proxy settings

    In CloudCenter Suite it is possible to specify proxy settings at the region level, as described here, and at the suite level. To understand the expected behavior when proxy settings are specified at both levels, see Precedence of Proxy Settings.

    Download Configuration and Encryption Key

    After saving the Region Configuration settings in the Workload Manager or Cost Optimizer UI, you can download them to your local computer and then upload them to other conditional components such as Cloud Remote.

    Click the Download Configuration link in the upper right of the Region Connectivity section, as shown in the following screenshot.

    Clicking Download Configuration causes two things to happen:

    • An encrypted zip file named artifacts.zip is downloaded by your browser. Make a note of the location of this zip file as you will need if you are using Cloud Remote.

    • The Region Connectivity section header updates to display a Copy Encryption Key link, as shown in the following screenshot.

    Click the Copy Encryption Key link to save the key to your clipboard. A success message will be display temporarily above the Region Connectivity section header. Make sure not to overwrite the clipboard with other data. You will need the key when you upload the configuration zip file to conditional components like Cloud Remote.

    If you change the connectivity settings in the CloudCenter Suite UI and need to again download the zip file from software.cisco.com, use the automatically create (new) encryption key, and copy the key to the clipboard by clicking the Copy Encryption Key link again.


    When you are done editing the settings in the dialog box, click Save.

  3. Determine if you need Cloud Remote for this region. Scroll down to the Region Connectivity section for the region and click on the Configure Region link in the upper right to open the Configure Region dialog box. The toggle settings should be the same as when you set them in the connectivity page of the Add Cloud dialog box. If all of the connectivity toggles in the Region Connectivity dialog box are set to Yes, then Cloud Remote is NOT needed for this cloud region. In this case, you would normally leave all region connectivity settings at their current values and continue to the next settings section. 

    The exception to this guidance is when a NAT firewall or proxy server exists between the CloudCenter Suite management cluster and worker VMs, or between the CloudCenter Suite management cluster and users that would use Workload Manager to initiate a Guacamole remote connection to a worker VM. In either of these cases, override the address fields in the Region Connectivity dialog box as explained below.

    Networking Constraint

    Field

    Value

    Worker VMs must use a proxy server or NAT firewall to access the "local" AMQP server running in the CloudCenter Suite cluster.Worker AMQP IP AddressIP address and port number that the firewall or proxy server presents to the worker VMs on behalf of the "local" AMQP server running in the CloudCenter Suite cluster.
    Users must use a proxy server or NAT firewall to access the Guacamole server running in the CloudCenter Suite cluster.Guacamole Public IP Address and PortIP address and port number that the firewall or proxy server presents to users on behalf of the Guacamole server running in the CloudCenter Suite cluster.

    Click OK to save the changes and dismiss the dialog box. You can now proceed to the next region settings section: VM Naming and IPAM Strategy.

  4. If any of the connectivity toggles in the Region Connectivity dialog box are set to No, then you must install and configure Cloud Remote for this region

     Steps to configure Cloud Remote in an OpenStack cloud region

    Configure Cloud Remote in an OpenStack Region

    Configure Cloud Remote in an OpenStack region as follows.

    Download and Launch the Cloud Remote Appliance in OpenStack

    1. Download the Cloud Remote appliance qcow2 file from software.cisco.com.

    2. Through the OpenStack console, import and launch the Cloud Remote appliance. This process is similar to importing and launching the CloudCenter Suite installer appliance for OpenStack.

      Do not add ‘Network Ports’ while launching a Cloud Remote instance in OpenStack.

    3. Optional but recommended for production environments: Deploy two additional instances of the appliance to form a cluster for HA. Cloud Remote includes support for clustering of multiple nodes. You will "add" these two additional instances to the first instance after the first instance is configured. See Cloud Remote (Conditional) > Scaling for details.

    4. Once the first instance of the appliance has been launched, use the OpenStack console to note its IP public and private addresses. You will need this information later on in order login to the Cloud Remote web UI and to complete the Region Connectivity settings in the CloudCenter Suite Web UI. Also, note the IP addresses of any other appliances you launch.


    Setup Cloud Remote Firewall Rules for a VM-based Cloud Region

    After you deploy the Cloud Remote appliance, you will need to open various ports on each instance of the appliance. To do this, use the tools provided by the cloud provider to create a new security group for your Cloud Remote cluster; then, associate each appliance in the cluster with that security group. Use the tables below for guidance on what port rules should be added to that security group.

    Port rules for a single node Cloud Remote deployment:

    PortProtocolSourceUsage
    22TCPLimit to address space of users needing SSH access for debugging and changing default portsSSH
    443TCPLimit to address space of users needing access to the Cloud Remote web UI for setup and scalingHTTPS (Cloud Remote web UI)
    8443TCPLimit to address space of users needing SSH or RDP access to their managed VMsUser to Guacamole
    5671TCPLimit to address space of the managed VMs and the address of the CloudCenter Suite cluster's local AMQP serviceAMQP
    15671TCPLimit to address space of users needing web access for debugging the remote AMQP serviceHTTPS (AMQP Management)
    7789TCPLimit to address space of the managed VMsWorker VM to Guacamole

    The Cloud Remote web UI, User-to-Guacamole, and AMQP ports listed above are the defaults used by Cloud Remote. You may change these port numbers using the Change Ports shell script (see Cloud Remote (Conditional) > Custom Port Numbers (Conditional)) once the appliance is fully configured and communicating with the CloudCenter Suite cluster. If you plan to modify any of these three port numbers, update the firewall rules accordingly.

    For a multi-node Cloud Remote cluster deployment, these additional port rules should be added to the same security group used for the single node configuration:

    PortProtocolSource
    2377TCP<cr_sec_group> *
    25672TCP<cr_sec_group>
    7946UDP<cr_sec_group>
    4369TCP<cr_sec_group>
    9010TCP<cr_sec_group>
    4789UDP<cr_sec_group>

     * <cr_sec_group> represents the security group that all Cloud Remote nodes are joined to.

    Specify AMQP and Guacamole Addresses for Supporting Cloud Remote

    From the CloudCenter Suite UI, for the cloud region requiring Cloud Remote, navigate to the corresponding Regions or Details tab. Click the Configure Region link in the upper left of the Region Connectivity section to bring up the Configure Region dialog box. The toggle settings should be the same as when you set them in the connectivity page of the Add Cloud dialog box. You must update some of the address fields in the dialog box according to the scenarios summarized in the table below.

    Toggle SettingsFieldValue

    Worker VMs Directly Connect with CloudCenter = No
    AND
    CloudCenter Directly Accessible from Cloud Remote = Yes

    Local AMQP IP Address

    Pre-populated with the address and port number of the "local" AMQP server running in the CloudCenter Suite cluster. This address must be accessible to Cloud Remote

    If Cloud Remote is accessing the CloudCenter Suite cluster through a user-supplied proxy server or NAT firewall, overwrite this field with the corresponding local AMQP IP address and port number provided by the user-supplied proxy server or NAT firewall and accessible to Cloud Remote.

    Worker VMs Directly Connect with CloudCenter = No
    AND
    CloudCenter Directly Accessible from Cloud Remote = No
    Remote AMQP IP Address

    Enter <Cloud_Remote_IP>:<amqp_port>, where
    <Cloud_Remote_IP> = the IP address Cloud Remote which is accessible to the CloudCenter Suite cluster, and
    <amqp_port> = 5671 OR the custom AMQP port number you would later set with the Change Ports shell script on the Cloud Remote appliance (see Cloud Remote (Conditional) >
    Custom Port Numbers (Conditional)).

    If there is no user-supplied NAT firewall or proxy server between the CloudCenter Suite cluster and Cloud Remote, the IP address would be the public IP address of Cloud Remote.

    If there is a NAT firewall or proxy server between the CloudCenter Suite cluster and Cloud Remote, instead, enter the corresponding public IP address and port number that the firewall or proxy server presents to the internet on behalf of the "remote" AMQP server running in Cloud Remote.


    Worker VMs Directly Connect with CloudCenter = NoWorker AMQP IP Address

    Enter <Cloud_Remote_IP>:<amqp_port>, where
    <Cloud_Remote_IP> = the Cloud Remote IP address accessible to the worker VMs, and
    <amqp_port> = 5671 OR the custom AMQP port number you would later set with the Change Ports shell script on the Cloud Remote appliance (see Cloud Remote (Conditional) > Custom Port Numbers (Conditional)).

    Worker VMs Directly Connect with CloudCenter = NoGuacamole Public IP and PortEnter <Cloud_Remote_IP>:<guac_port>, where
    <Cloud_Remote_IP> = the Cloud Remote IP address accessible to CloudCenter Suite users, and
    <guac_port> = 8443 OR the custom Guacamole port number you would later set with the Change Ports shell script on the Cloud Remote appliance (see Cloud Remote (Conditional) > Custom Port Numbers (Conditional)).
    Worker VMs Directly Connect with CloudCenter = NoGuacamole IP Address and Port for Application VMsEnter <Cloud_Remote_IP>:<guac_port>, where
    <Cloud_Remote_IP> = the Cloud Remote IP address accessible to worker VMs, and
    <guac_port> = 7789

    When done, click OK to save the setting and dismiss the dialog box.

    Download Region Connectivity Settings and Upload to Cloud Remote

    Cloud Remote uses the region connectivity settings set in the Workload Manager or Cost Optimizer UI. After saving the Region Configuration settings in the Workload Manager or Cost Optimizer UI, you must download them and to your local computer and then upload them to Cloud Remote as follows.

    Click the Download Configuration link in the upper right of the Region Connectivity section, as shown in the figure below.

    Clicking Download Configuration causes two things to happen:

    • An encrypted zip file named artifacts.zip will be downloaded by your browser. Make note of the location of this zip file as you will need to upload it to Cloud Remote through the Cloud Remote web UI (see below).

    • The Region Connectivity section header updates to display a Copy Encryption Key link, as shown in figure below. 

    Click the Copy Encryption Key link to save the key to your clipboard. A success message will be display temporarily above the Region Connectivity section header. Make sure not to overwrite the clipboard with other data. You will need the key when you upload the configuration zip file to Cloud Remote.

    If you change the connectivity settings in the CloudCenter Suite UI and need to again download the zip file, a new encryption key is automatically created and can be copied to the clipboard by clicking the Copy Encryption Key link again.

    After you have downloaded the zip file and copied the encryption key to your clipboard, login to Cloud Remote web UI.

    1. Open another browser tab and login to https://<Cloud Remote_ip> with the default credentials: admin / cisco. 

    2. You will immediately be required to change your password. Do so now. 

    3. You are now brought to the Cloud Remote home page as shown in the figure below.

    4. Click the Apply Configuration button in the page header. This prompts you to select a configuration file and enter the encryption key as shown in the figure below.

    5. Paste the encryption key that was copied to the clipboard into the Encryption Key field in the dialog box.

    6. Click Select File and browse to the artifacts.zip file that you downloaded through the CloudCenter Suite web UI and select it.

    7. Click Confirm.

    8. Once the zip file is successfully transmitted and accepted, the Cloud Remote appliance attempts to establish communication with the CloudCenter Suite cluster and the Cloud Remote web UI home page is updated to show the name of the region it is connecting to in the upper right (see figure below).

    Switch your focus back to the Region Connectivity section of the target cloud region in the CloudCenter Suite web UI. The status indicator in the Region Connectivity section header will change from Not Configured to Running once connectivity between  Cloud Remote and the CloudCenter Suite cluster is completely established (see figure below).

    After completing these steps, Workload Manager and Cost Optimizer can use Cloud Remote for communicating with the target cloud region.


  5. VM Naming and IPAM Strategy (conditional): Configure any VM naming or IPAM strategies in the Strategy section as explained in VM Naming and IPAM Strategies. If you leave the settings at the defaults, no IPAM strategy is applied and the default VM naming strategy is applied.

  6. External Lifecycle Actions (conditional): Specify any external lifecycle actions to be performed on all VMs launched by Workload Manager in this region as explained in External Lifecycle Actions Settings

  7. Instance Types: For OpenStack clouds, you can sync all instance types (flavors) defined in OpenStack to CloudCenter Suite on demand. To manually sync OpenStack instance types, click the Sync Instance Types link in the upper right of the instances types section. Alternatively, you can manually add instance types, one by one, by clicking the Add Instance Types link in the upper right of the instances types sections. If you add an instance type manually, you must ensure that the instance ID you enter in CloudCenter Suite exactly matches the corresponding flavor ID in OpenStack. Furthermore, during application deployment, the CPU, RAM and storage parameters defined in the OpenStack flavor will override any of the corresponding parameters defined in CloudCenter Suite. See Instance Types Settings for more details.

  8. Storage Types (conditional): For private VM-based clouds like OpenStack, CloudCenter Suite uses storage types for cost tracking purposes. CloudCenter Suite creates a default storage type with zero cost. You would manually edit this storage type to enter your own cost factor. You can optionally add more storage types to your OpenStack region. See Storage Types Settings for more details.

  9. Image Mappings: Image mappings allow services based on CloudCenter Suite logical images to be deployed using the appropriate physical image stored on the target cloud region. You must manually import these physical images into your OpenStack region and then map the appropriate CloudCenter Suite logical images to these physical images. See Images for more context.
