11.2. 为 director Operator 运行 overcloud 更新准备

流程

1. 修改名为 fencing.yaml 的 heat 参数 ConfigMap，以在更新期间禁用隔离：

   parameter_defaults:
     EnableFencing: false

   Copy to Clipboard Toggle word wrap

2. Create an OpenStackConfigGenerator resource called osconfiggenerator-update-prepare.yaml:

   $ cat <<EOF > osconfiggenerator-update-prepare.yaml
   apiVersion: osp-director.openstack.org/v1beta1
   kind: OpenStackConfigGenerator
   metadata:
     name: "update"
     namespace: openstack
   spec:
     gitSecret: git-secret
     heatEnvs:
       - lifecycle/update-prepare.yaml
     heatEnvConfigMap: heat-env-config-update
     tarballConfigMap: tripleo-tarball-config-update
   EOF

   Copy to Clipboard Toggle word wrap

3. 应用配置：

   $ oc apply -f osconfiggenerator-update-prepare.yaml

   Copy to Clipboard Toggle word wrap
4. 等待更新准备过程完成。
