kubernetes - 如何将 env 值用于 Job？

Question

您好，我正在尝试将 env 值传递给作业以执行此操作，我使用以下 kubernetes 模板:

apiVersion: batch/v1
kind: Job
metadata:
  name: socksdownloader
spec:
  template:
    spec:
      containers:
      - name: socksdownloader
        image: socksdownloader:0.0.1
   #     env:
   #     - name: REDIS_HOST
   #       value: redis
   #     - name: REDIS_PORT
   #       value: 6379
   #     - name: REDIS_DB
   #       value: 0
   #     - name: REDIS_KEY
   #       value: "SOCK:"
        command: ["python",  "src/main.py"]
      restartPolicy: Never
  backoffLimit: 4

如果我取消注释 yml 的 env 条目，我会收到以下错误:

The request is invalid: patch: Invalid value:"map[metadata:map[annotations:map[kubectl.kubernetes.io/last-applied-configuration:{"apiVersion":"batch/v1","kind":"Job","metadata":{"annotations":{},"name":"socksdownloader","namespace":"default"},"spec":{"backoffLimit":4,"template":{"spec":{"containers":[{"command":["python","src/main.py"],"env":[{"name":"REDIS_HOST","value":"redis"},{"name":"REDIS_PORT","value":6379},{"name":"REDIS_DB","value":0},{"name":"REDIS_KEY","value":"SOCK:"}],"image":"socksdownloader:0.0.1","name":"socksdownloader"}],"restartPolicy":"Never"}}}}\n]]spec:map[template:map[spec:map[]]]]": cannot convert int64 to string

问题是我如何将这些值传递给 Job 以便可以连接到 redis。

谢谢

Kubernetes' envvar规范要求将环境变量值强制转换为字符串，因此整数需要通过引号传递。

在整数值中使用引号:

- name: REDIS_PORT
  value: "6379"
- name: REDIS_DB
  value: "0"
