This usage is based on the project of https://github.com/birdayz/kaf

Description

A Kafka cluster in your Kubernetes Cluster
If you're in China, Please make sure you have the proxy setup in your Kubernetes cluster as what I did

Steps

学习 goroutine 的异步执行并传参，具体参考：https://www.runoob.com/go/go-concurrent.html

package main

import (
	"log"
	"time"
)

Cron 表达式转换为日期

主要使用 https://github.com/caryyu/cronexpr 命令工具

MacOS - cronexpr -n 1 "30 16 * * *" | {read t; date -r "$t"}
Linux - cronexpr -n 1 "30 16 * * *" | {read t; date --date=@"$t"}

Date 日期调整（加一天，加一小时，等）

MacOS - date -v+1d/date -v-1d/date -v+1H

vault write auth/userpass/users/caryyu password="xxxxxxxxxxxx" 

vault auth list -detailed

vault policy list

vault write identity/entity name="caryyu" policies="policy-1,policy-2"

vault write identity/entity-alias name="caryyu" mount_accessor=auth_userpass_7cde8625
