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。您可以将特定节点上的镜像设置为 overcloud-minimal，或将角色的所有节点设置为 overcloud-minimal。

   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: CephStorage
     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: CephStorage
     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. 置备节点：

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

5. 部署 overcloud：

   (undercloud)$ openstack overcloud ceph deploy \
   --ntp-server <ntp_server> \ 

   1

   
   --tld <domain_name> \ 

   2

   
   --config initial-ceph.conf \
   --network-data network_data.yaml -o deployed_ceph.yaml \
   --roles-data roles_data.yaml \
   --container-image-prepare ~/containers-prepare-parameter.yaml overcloud-baremetal-deployed.yaml

   将 <ntp_server > 替换为适用的 NTP 服务器的 IP 地址。

   2

   将 <domain_name > 替换为所需的域名。
