2.5. 使用 overcloud-minimal 镜像来避免使用红帽订阅授权

流程

1. 打开 /home/stack/templates/overcloud-baremetal-deploy.yaml 文件。

2. 为您要使用 overcloud-minimal 镜像的节点添加或更新 image 属性。您可以在特定节点上将镜像设置为 overcloud-minimal，或针对角色的所有节点。

   注意

   overcloud 最小镜像不是整个磁盘镜像。内核和 ramdisk 必须在 /home/stack/templates/overcloud-baremetal-deploy.yaml 文件中指定。

   特定节点

   - name: Ceph
     count: 3
     instances:
     - hostname: overcloud-ceph-0
       name: node00
       image:
         href: file:///var/lib/ironic/images/overcloud-minimal.raw
         kernel: file://var/lib/ironic/images/overcloud-minimal.vmlinuz
         ramdisk: file://var/lib/ironic/images/overcloud-minimal.initrd
     - hostname: overcloud-ceph-1
       name: node01
       image:
         href: file:///var/lib/ironic/images/overcloud-minimal.raw
         kernel: file://var/lib/ironic/images/overcloud-minimal.vmlinuz
         ramdisk: file://var/lib/ironic/images/overcloud-minimal.initrd
     - hostname: overcloud-ceph-2
       name: node02
       image:
         href: file:///var/lib/ironic/images/overcloud-minimal.raw
         kernel: file://var/lib/ironic/images/overcloud-minimal.vmlinuz
         ramdisk: file://var/lib/ironic/images/overcloud-minimal.initrd

   特定角色的所有节点

   - name: Ceph
     count: 3
     defaults:
       image:
         href: file:///var/lib/ironic/images/overcloud-minimal.raw
         kernel: file://var/lib/ironic/images/overcloud-minimal.vmlinuz
         ramdisk: file://var/lib/ironic/images/overcloud-minimal.initrd
     instances:
     - hostname: overcloud-ceph-0
       name: node00
     - hostname: overcloud-ceph-1
       name: node01
     - hostname: overcloud-ceph-2
       name: node02

3. 在 roles_data.yaml 角色定义文件中，将 rhsm_enforce 参数设置为 False。

   rhsm_enforce: False

4. 运行 provisioning 命令：

   (undercloud)$ openstack overcloud node provision \
   --stack overcloud \
   --output /home/stack/templates/overcloud-baremetal-deployed.yaml \
   /home/stack/templates/overcloud-baremetal-deploy.yaml

5. 将 overcloud-baremetal-deployed.yaml 环境文件传递给 openstack overcloud ceph deploy 命令。
