红帽全球峰会1.19. 采用自动扩展
采用自动扩展意味着应该禁用 Aodh 服务的现有 OpenStackControlPlane CR 应该被修补，以使用源环境提供的配置参数启动该服务。
本指南还假设：
-
TripleO环境（源云）在一个端运行； -
SNO/CodeReadyContainers在另一端运行。
1.19.1. 先决条件

- 以前的 Adoption 步骤已完成。应已经采用 MariaDB、Keystone、Heat 和 Telemetry。
1.19.2. 流程 - 自动扩展采用

修补 OpenStackControlPlane 以部署自动扩展服务：
cat << EOF > aodh_patch.yaml
spec:
autoscaling:
enabled: true
prometheus:
deployPrometheus: false
aodh:
customServiceConfig: |
[DEFAULT]
debug=true
secret: osp-secret
passwordSelectors:
databaseUser: aodh
databaseInstance: openstack
memcachedInstance: memcached
EOF对 OpenStackControlPlane 进行补丁来部署 Aodh 服务：
oc patch openstackcontrolplane openstack --type=merge --patch-file aodh_patch.yaml1.19.3. post-checks

1.19.3.1. 如果启用了自动扩展服务，请检查 Aodh pod

AODH_POD=`oc get pods -l service=aodh | tail -n 1 | cut -f 1 -d' '`
oc exec -t $AODH_POD -c aodh-api -- cat /etc/aodh/aodh.conf1.19.3.2. 检查 Aodh API 服务是否在 Keystone 中注册
