004k8s pods volumes和pod的对应关系查询

一、背景

如二、描述所示pods频繁地重启,导致听云的探针收集规则文件占用大量的空间,需要查询"063915dd-c5b8-4137-9e9c-119488992b56"对应的是哪个pod

听云data下存储的探针收集规则:

二、对应pod查询

kubectl get po -A -o json | \
pipe>     jq --arg pod_uuid 063915dd-c5b8-4137-9e9c-119488992b56  -r '.items[] 
      | select(.metadata.uid == $pod_uuid) 
      | "uuid \($pod_uuid) is \(.metadata.name)"'
uuid 063915dd-c5b8-4137-9e9c-119488992b56 is fp-mission-api-7bfcd67589-2txkk

三、对应查询听云探针版本

#直接看该deployment的名字xx-mission-api的yaml详细配置看不到听云探针,因为是注入的,所以需要用describe去看 
❯ kubectl -n dev describe pods xx-mission-api-7bfcd67589-2txkk
Name:         xx-mission-api-7bfcd67589-2txkk

四、听云V2.3.0.0对以上问题的修复
