Kubernetes (commonly referred to as "K8s") is an open source system for automating deployment, scaling and management of containerized applications originally designed by Google and donated to the Cloud Native Computing Foundation. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It supports a range of container tools, including Docker.

What would you like to be added?

The changes to support snapshot tests for Generic Ephemeral Volumes kubernetes/kubernetes#105659 generated some duplicated code in the file test/e2e/storage/testsuites/snapshottable.go as commented here: kubernetes/kubernetes#105659 (comment), it'd be great to create functions that are reused in b

Hi,

first thanks for this awesome software. But I have some trouble and I don't know how to proceed. First I try to find out what else I could provide for this report to be a good bug report.

First, I use the latest version (v1.14.0) from openSUSE build Service. I know, I should compile it by my self to avoid any other causes for this behavior. But for now I still use this package from there

Is there an existing issue for this?

  • I have searched the existing issues

Kong version ($ kong version)

2.5.1.0

Current Behavior

When calling kong.response.exit(), the function automatically sets the Content-Length header on the response even if the Transfer-Encoding header is present. This is in violation of RFC 7230 3.3.2:

A sender MUST NOT send a Content-

1.4.2版本注册中心测试结论如下:

  1. 在无鉴权情况下,7w dubbo实例已出现瓶颈。

  2. 在有鉴权情况下,3w dubbo实例已出现瓶颈。

  3. 当开启鉴权且达到3万dubbo实例,服务端主要参数的最佳实践为:tomcat最大线程数=4000,最小空闲线程数=200,nacos的鉴权缓存=true。

问题:

如何继续提升dubbo实例数?因为我们实例已经达到1.5万,并且要添加鉴权功能,后续会继续增加,明年年末预计会到8万实例。 @KomachiSion 多谢啦

另外,实例数个数我们是查看的naming-performance.log 和控制台


附[Nacos注册中心性能测试报告],如有问题,请指正,以便我们更好的测试注册中心性能。

Kubernetes cluster cert expires after a year. After the expiration the cert need to be updated. There needs to a way of notifying the user of this expiration through logging. One way could be using Kubernetes events to log the warning at the expiration event. Please refer to the epic for this for more context : dapr/cli#807

Feel free to chime in with more ideas around

Scenario:

  • Single vttablet, connecting to external MySQL (happens to be RDS Aurora, but I doubt it matters).
  • Single unsharded keyspace (keyspace3), no vschema, with a single table, containing a single row
  • Test program using the Python pymysql driver, using the CLIENT.FOUND_ROWS flag, and updating a single row to it's current key value (i.e. no rows are updated, but a single row
