先决条件

如果集群中只有一个节点,则至少需要 6 个 CPU、6 GB 内存和 30 GB 磁盘存储。
如果集群中有多个节点,则每个节点至少需要 2 个 CPU、4 GB 内存和 20 GB 磁盘存储。
您有一个使用 Kubernetes v1.24 或更高版本的集群。

部署 Knative Serving 流程

1.  部署Service自定义资源
2.  部署Serving核心组件
3.  部署网络层(networking layer)组件
    1. Istio、Contour和Kourier三选一
4. (可选)配置DNS
5. (可选)部署Serving扩展
    1. HPA:用于支持Kubernetes的HPA
    2. Cert Manager:用于为工作负载自动签发TLS证书
    3. Encrypt HTTP01:用于为工作负载自动签发TLS证书
6.  部署kn
