但是当我试图查看日志时,什么也没有出现
al8-1@al8-1:~/kuber_test/pod_nginx$ kubectl logs pod-apigw2
al8-1@al8-1:~/kuber_test/pod_nginx$ kubectl logs pod-apigw2 -p
al8-1@al8-1:~/kuber_test/pod_nginx$
这是我的 yaml 文件
apiVersion: v1
kind: Pod
metadata:
name: pod-apigw2
spec:
selector:
app: apigw2
containers:
- name: apigw2
image: parkdongwoo/apigw_test:v1
imagePullPolicy: Always
ports:
- name: port-apigw2
containerPort: 8080
如果我通过“docker run”运行 docker 映像,我可以毫无问题地运行该映像,但只有通过 kubernetes 我才会崩溃。
有人可以帮我吗,我如何在没有看到任何日志的情况下进行调试?
