Kubernetes 工作永无止境

Question

我有一个 k8 作业，使用 sqlpackage 工具发布一个 sql-server dacpac。作业运行，数据库部署成功，但作业卡在Running状态。

如何确保作业在 sqlpackage 完成运行后结束？

在 Kubernetes 中定义作业时，您可以设置属性 activeDeadlineSeconds。

apiVersion: batch/v1
kind: Job
metadata:
  name: your-job
spec:
  activeDeadlineSeconds: 100
  template:
    spec:
      containers:
      - [...]
