我有一个WebSocket粘性会话的问题。问题是我在Kubernetes部署上有2个Pod，我的应用使用WebSocket，问题是它不会坚持相同的pod-s。我读到我需要添加一个会话关联到入口NGNIX负载均衡器，但它不会工作。我无法在浏览器中创建cookie。我将此标注添加到我的NGNIX入口：

nginx.ingress.kubernetes.io/affinity: "cookie"
nginx.ingress.kubernetes.io/session-cookie-name: "http-cookie"
nginx.ingress.kubernetes.io/session-cookie-expires: "172800"
nginx.ingress.kubernetes.io/session-cookie-max-age: "172800"

字符串
但它不会工作。我的部署YAML看起来像这样：

我读到我需要添加这个注解来使其工作，但它不会工作。我想提一下，ingress和deployment不在同一个命名空间中，这是一个问题吗？我读到这可能是一个问题，但我不确定，如果是，有什么方法可以让它工作吗？
