2.3. 为叶网络创建类别和标记节点

流程

1. Source stackrc 文件：

   $ source ~/stackrc

2. 为每个自定义角色创建类别：

   $ ROLES="control0 compute_leaf0 compute_leaf1 compute_leaf2 ceph-storage_leaf0 ceph-storage_leaf1 ceph-storage_leaf2"
   $ for ROLE in $ROLES; do openstack flavor create --id auto --ram 4096 --disk 40 --vcpus 1 $ROLE ; done
   $ for ROLE in $ROLES; do openstack flavor set --property "cpu_arch"="x86_64" --property "capabilities:boot_option"="local" --property "capabilities:profile"="$ROLE" $ROLE ; done

3. 将节点标记为其对应的 leaf network。例如，运行以下命令，将具有 UUID 58c3d07e-24f2-48a7-bbb6-6843f0e8ee13 的节点标记到 Leaf2 上的计算角色：

   $ openstack baremetal node set --property capabilities='profile:compute_leaf2,boot_option:local' 58c3d07e-24f2-48a7-bbb6-6843f0e8ee13

4. 创建一个环境文件(~/templates/node-data.yaml)，其中包含类别到角色的映射：

   parameter_defaults:
     OvercloudController0Flavor: control0
     Controller0Count: 3
     OvercloudCompute0Flavor: compute_leaf0
     Compute0Count: 3
     OvercloudCompute1Flavor: compute_leaf1
     Compute1Count: 3
     OvercloudCompute2Flavor: compute_leaf2
     Compute2Count: 3
     OvercloudCephStorage0Flavor: ceph-storage_leaf0
     CephStorage0Count: 3
     OvercloudCephStorage1Flavor: ceph-storage_leaf1
     CephStorage1Count: 3
     OvercloudCephStorage2Flavor: ceph-storage_leaf2
     CephStorage2Count: 3

   您还可以使用每个对应的 *Count' 参数设置要在 overcloud 中部署的节点数量。
