我正在尝试curl在中的容器内执行命令gke。
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: app
spec:
schedule: "* * * * *"
jobTemplate:
spec:
template:
spec:
containers:
- name: app
image: appropriate/curl
env:
- name: URL
value: "https://app.com"
- name: PASSWORD
value: "pass"
args: ["-vk", "-H", "\"Authorization: Bearer $(PASSWORD)\"", "$(URL)"]
restartPolicy: OnFailure
错误：
curl: option -vk -H "Authorization: Bearer pass" https://app.com: is unknown
我只是无法找到如何使用环境变量curl在args字段中执行。
该curl命令在我的PC中有效。
我究竟做错了什么？
如何将env vars与容器curl命令args集成？
您无需将auth标头用引号引起来，kubernetes会为您完成。
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: app
spec:
schedule: "* * * * *"
jobTemplate:
spec:
template:
spec:
containers:
- name: app
image: appropriate/curl
env:
- name: URL
value: "app.com"
- name: PASSWORD
value: "pass"
args: ["-vk", "-H", "Authorization: Bearer $(PASSWORD)", "$(URL)"]
restartPolicy: OnFailure
您可以执行以下操作来测试输出yaml：
kubectl apply -f job.yaml -o yaml --dry-run
这表明最终输出很好
apiVersion: batch/v1beta1
kind: CronJob
metadata:
annotations:
kubectl.kubernetes.io/last-applied-configuration: |
{"apiVersion":"batch/v1beta1","kind":"CronJob","metadata":{"annotations":{},"name":"app","namespace":"default"},"spec":{"jobTemplate":{"spec":{"template":{"spec":{"containers":[{"args":["-vk","-H","Authorization: Bearer $(PASSWORD)","$(URL)"],"env":[{"name":"URL","value":"https://app.com"},{"name":"PASSWORD","value":"pass"}],"image":"appropriate/curl","name":"app"}],"restartPolicy":"OnFailure"}}}},"schedule":"* * * * *"}}
