  7. In the Password field, enter the SSH password for image access.
  8. From the Image list, select an image from the Red Hat OpenStack Platform compute resource.
  9. Optional: Select the User Data checkbox if the image supports user data input, such as cloud-init data.
  10. Click Submit to save the image details.

CLI procedure

  • Create the image with the hammer compute-resource image create command. Use the --uuid field to store the full path of the image location on the Red Hat OpenStack Platform server. 

    # hammer compute-resource image create \
--name "OpenStack Image" \
--compute-resource "My_OpenStack_Platform"
--operatingsystem "RedHat version" \
--architecture "x86_64" \
--username root \
--user-data true \
--uuid "/path/to/OpenstackImage.qcow2"

13.3. Adding Red Hat OpenStack Platform Details to a Compute Profile

Use this procedure to add Red Hat OpenStack Platform hardware settings to a compute profile. When you create a host on Red Hat OpenStack Platform using this compute profile, these settings are automatically populated.

Procedure

  1. In the Satellite web UI, navigate to Infrastructure > Compute Profiles.
  2. In the Compute Profiles window, click the name of an existing compute profile, or click Create Compute Profile, enter a Name, and click Submit.
  3. Click the name of the Red Hat OpenStack Platform compute resource.
  4. From the Flavor list, select the hardware profile on Red Hat OpenStack Platform to use for the host.
  5. From the Availability zone list, select the target cluster to use within the Red Hat OpenStack Platform environment.
  6. From the Image list, select the image to use for image-based provisioning.
  7. From the Tenant list, select the tenant or project for the Red Hat OpenStack Platform instance.
  8. From the Security Group list, select the cloud-based access rules for ports and IP addresses.
  9. From the Internal network, select the private networks for the host to join.
  10. From the Floating IP network, select the external networks for the host to join and assign a floating IP address.
  11. From the Boot from volume, select whether a volume is created from the image. If not selected, the instance boots the image directly.
  12. In the New boot volume size (GB) field, enter the size, in GB, of the new boot volume.
  13. Click Submit to save the compute profile.

CLI procedure

  • Set Red Hat OpenStack Platform details to a compute profile: 

    # hammer compute-profile values create
--compute-resource "My_Laptop" \
--compute-profile "My_Compute_Profile" \
--compute-attributes "availability_zone=My_Zone,image_ref=My_Image,flavor_ref=m1.small,tenant_id=openstack,security_groups=default,network=My_Network,boot_from_volume=false"

13.4. Creating Image-based Hosts on Red Hat OpenStack Platform

In Satellite, you can use Red Hat OpenStack Platform provisioning to create hosts from an existing image. The new host entry triggers the Red Hat OpenStack Platform server to create the instance using the pre-existing image as a basis for the new volume.

To use the CLI instead of the Satellite web UI, see the CLI procedure.

Procedure

  1. In the Satellite web UI, navigate to Hosts > Create Host.
  2. In the Name field, enter a name for the host.
  3. Optional: Click the Organization tab and change the organization context to match your requirement.
  4. Optional: Click the Location tab and change the location context to match your requirement.
  5. From the Host Group list, select a host group that you want to assign your host to. That host group will populate the form.
  6. From the Deploy on list, select the Red Hat OpenStack Platform connection.
  7. From the Compute Profile list, select a profile to use to automatically populate virtual machine settings.
  8. From the Lifecycle Environment list, select the environment.
  9. Click the Interfaces tab, and on the interface of the host, click Edit.

  10. Verify that the fields are populated with values. Note in particular:

    • Satellite automatically assigns an IP address for the new host.
    • Ensure that the MAC address field is blank. Red Hat OpenStack Platform assigns a MAC address to the host during provisioning.
    • The Name from the Host tab becomes the DNS name.
    • Ensure that Satellite automatically selects the Managed, Primary, and Provision options for the first interface on the host. If not, select them.
  11. Click OK to save. To add another interface, click Add Interface. You can select only one interface for Provision and Primary.
  12. Click the Operating System tab, and confirm that all fields automatically contain values.
  13. If you want to change the image that populates automatically from your compute profile, from the Images list, select a different image to base the new host’s root volume on.
  14. Click Resolve in Provisioning templates to check the new host can identify the right provisioning templates to use.
  15. Click the Virtual Machine tab and confirm that these settings are populated with details from the host group and compute profile. Modify these settings to suit your needs.
  16. Click the Parameters tab, and ensure that a parameter exists that provides an activation key. If not, add an activation key.
  17. Click Submit to save the host entry.

CLI procedure

  • Create the host with the hammer host create command and include --provision-method image. Replace the values in the following example with the appropriate values for your environment. 

    # hammer host create \
--compute-attributes="flavor_ref=m1.small,tenant_id=openstack,security_groups=default,network=mynetwork" \
--compute-resource "My_OpenStack_Platform" \
--enabled true \
--hostgroup "Base" \
--image "OpenStack Image" \
--interface "managed=true,primary=true,provision=true" \
--location "New York" \
--managed true \
--name "openstack-host1" \
--organization "My_Organization" \
--provision-method image
