如何使用kubernetes在cronJob中触发restAPI[POST，其标头具有身份验证和参数]。当我创建cron并尝试运行它时，我得到了以下错误
curl: (7) Failed to connect to localhost port 8080: Connection refused
当我用实际主机而不是本地主机替换主机时，它仍然会将错误显示为
curl: (6) Could not resolve host : xxxHostName
我可以使用命令提示符以及在POSTMAN 中击中卷曲
以下是我正在尝试运行的cronJob
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: e2em-rule-violation-job
spec:
schedule: "*/3 * * * *"
concurrencyPolicy: Allow
failedJobsHistoryLimit: 1
successfulJobsHistoryLimit: 3

restartPolicy: OnFailure
以下是成功的试运行，但乔布斯在创建时失败了

你的问题出在上面的卷曲上。看，你正试图卷曲不存在的地址。运行cronjob后会发生什么？
- k8s创建
cronjobe2em-rule-violation-job cronjobe2em-rule-violation-job创建POD- curl命令正试图从该POD的内部运行
你的POD不知道localhost:8080是什么。与你的应用程序运行的地方相比，你的POD绝对有另一个本地成本。。。此地址未公开，您无法访问它。另外，image: curlimages/curl:7.72.0dockerfile没有公开端口8080。。
你能做的测试是
- 使用curl pod创建正常部署，比如
NEWCURLPOD - 连接到
NEWCURLPOD并执行您想要运行的初始命令。示例：kubectl exec -ti {NEWCURLPOD} -n {PROPER_NAMESPACE} -- curl blablabla
如果这不起作用-检查dns。如果你的应用程序在同一个集群中运行，你应该正确地公开它的服务以到达目标，但可以肯定的是，这不是localhost:8080
干式运行。。
以下是成功的试运行，但当创建
在运行试运行时-它只检查和预览对象，不应该在那里执行curl-结果你会看到它成功完成。
