如何执行从POD A到另一个POD B的shell脚本

Question

---

就像你说的那样，我创建了另一个pod，它是同类的：job，并包含script.sh.

在script.sh文件中；kubectl exec"到主吊舱运行几个命令

脚本被执行，但我得到错误"；无法创建资源"；API组中的pods/exec"；

因此，我用resources创建了一个clusterrole：["pods/exec"]，并使用ClusterRoleBinding 将其绑定到默认服务帐户

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: pod-reader
rules:
- apiGroups: [""]
resources: ["pods", "pods/log"]
verbs: ["get", "list"]
- apiGroups: [""]
resources: ["pods/exec"]
verbs: ["create"]
--- 
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
name: service-account-role-binding
namespace: default
subjects:
- kind: ServiceAccount
name: default
namespace: default
roleRef:
kind: ClusterRole
name: pod-reader
apiGroup: rbac.authorization.k8s.io
---
apiVersion: v1
kind: ServiceAccount
metadata:
name: default
namespace: default

In the pod which is of kind:job, I include the service account like shown below
restartPolicy: Never
serviceAccountName: default
but I still get the same error. What am I doing wrong here ?

Error from server (Forbidden): pods "mongo-0" is forbidden: User "system:serviceaccount:default:default" cannot create resource "pods/exec" in API group "" in the namespace "default"
