我添加后,
spec:
containers:
- args:
- /bin/sh
- '-c'
- touch /tmp/healthy; touch /tmp/liveness
env:
对于部署文件,应用程序不会在描述日志中正常运行。部署成功,但是没有输出。这两个文件都在容器中创建。我可以在kubernetes部署中运行docker build吗?
下面是完整的部署Yaml。

您的问题是container is not found
完成任务后。您被告知要对容器执行Shell脚本。然后,完成容器。这就是为什么您看不到文件是否已创建的原因。而且它没有放任何日志。因此,创建文件后,您需要保持容器活动。您可以通过放置无限的while循环来实现。来了:
apiVersion: apps/v1
kind: Deployment
metadata:
name: hello
labels:
app: hi
spec:
replicas: 1
selector:
matchLabels:
app: hi
template:
metadata:
labels:
app: hi
spec:
containers:
- name: hi
image: busybox
args:
- /bin/sh
- "-c"
- "touch /tmp/healthy; touch /tmp/liveness; while true; do echo .; sleep 1; done"
ports:
- containerPort: 80
将其保存到hello-deployment.yaml并运行,
$ kubectl create -f hello-deployment.yaml
$ pod_name=$(kubectl get pods -l app=hi -o jsonpath='{.items[0].metadata.name}')
$ kubectl logs -f $pod_name
$ kubectl exec -it -f $pod_name -- ls /tmp
