场景 1. 由于kubectl apply -f deployment.yaml时 在相同的镜像，没有做任何变更的情况下，无法触发更新 2. 于是采用kubectl patch -f deployment.yaml 的环境变量中追加时间的方式进行发布 结果 1. 在应用发布的这一个时刻瞬间出现两个pod, 在创建deployment时，同事会创建 replicasets.apps。 2. 发布后观察在同一时刻创建了两次replicasets.apps 3. 后通过 手动触发kubectl patch 的确产生了新的replicasets.apps，并生成一个新的pod [详解 Kubernetes Deployment 的实现原理](https://draveness.me/kubernetes-deployment/)
``` nginx stream 提供了四层代理。可以通过proxy_download_rate和proxy_upload_rate设置下载和上传限速。平时在七层http核心模块ngx_http_limit_conn_module这个模块提供limit_conn限速。 proxy_upload_rate 和proxy_download_rate分别配置从客户端读数据和从上游服务器读数据的速率，单位为每秒字节数，默认为0，不限速。 ``` ``` user www-data; worker_processes auto; pid /run/nginx.pid; events { worker_connections 1; } # 1) # Add a stream # This stream is used...
