Architecture Reference Documentation: https://grafana.com/blog/2018/12/12/loki-prometheus-inspired-open-source-logging-for-cloud-natives/ Distributor Once promtail collects and sends the logs to Loki, the distributor is the first component to receive them. Now we could be receiving millions of writes per second and we wouldn’t want to write them to a database as they come in. That would kill any database out there. We... » read more

很多流行的编程语言中都以某种方式提供迭代器，其中包括 C++、Java、Javascript、Python 和 Rust。Go 语言现在也加入了迭代器。iter 包是 Go 1.23 新增的标准库，提供了迭代器的基本定义和相关操作。 为什么需要迭代器 在 Go 1.18 引入泛型之后，便可以很方便的定义一些泛型容器类型来提升编码效率。 例如我们可以基于 map 类型定义了一个集合类型—— Set。 // Set 基于 map 定义一个存放元素的集合类型 type Set[E comparable] struct { m map[E]struct{} } // NewSet 返回一个 Set func NewSet[E comparable]() *Set[E] { return &Set[E]{m: make(map[E]struct{})} } // Add 向 Set 中添加元素 func (s *Set[E]) Add(v E) {... » read more

Ensuring all client requests are handled properly You now have a good sense of how to make pods shut down cleanly. Now, we’ll look at the pod’s lifecycle from the perspective of the pod’s clients (clients consuming the service the pod is providing). This is important to understand if you don’t want clients to run... » read more
The Kubernetes termination lifecycle Once Kubernetes has decided to terminate your pod, a series of events takes place. Let’s look at each step of the Kubernetes termination lifecycle. The container termination sequence 1 – Pod is set to the “Terminating” State and removed from the endpoints list of all Services At this point, the pod... » read more
在上一篇文章，我们实现了SSH 私钥的“内容直接输入与文件上传双重输入方式”，那么我们在 console 上主动生成一个 SSH 私钥（非本地上传），当请求成功时，如何本地能同时得到生成的私钥文件呢？ 实现 API 响应: { "code": 0, "message": "ok", "data": { "name": "test", "key_material": "-----BEGIN RSA PRIVATE KEY-----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\npxOHfLyTvv0lcv/1AqAhKzu7r64f5lyUMFNcF33LWifZBhcI+5s=\n-----END RSA PRIVATE KEY-----\n" } } 实现方案: 用户点击生成密钥对按钮 amis 请求后台，拿到密钥对 amis 自动弹出下载/保存对话或直接下载（JS动作，生成blob并自动触发下载） *** reload 当前界面 { "type": "container", "align": "right", "behavior": [ "FuzzyQuery" ], "body": [ { "type": "button", "label": "创建秘钥对", "onEvent": {... » read more
