我試圖在GKE上部署一個幽靈博客,工作於persistent disks with WordPress tutorial。我有手動運行罰款GKE節點上的工作容器:Google Container Engine上的Kubernetes窗格不斷重新啓動,從未準備好
kubectl run ghost --image=us.gcr.io/my_project_id/my-ghost-blog --port=2368
當我這麼做,我可以捲曲:
docker run -d --name my-ghost-blog -p 2368:2368 -d us.gcr.io/my_project_id/my-ghost-blog
使用下面的方法從另一教程中,我也可以正確地創建一個吊艙在內部IP的博客在集羣之內,並從kubectl get pod
以下的輸出:
Name: ghosty-nqgt0
Namespace: default
Image(s): us.gcr.io/my_project_id/my-ghost-blog
Node: very-long-node-name/10.240.51.18

的問題出現了,當我插件tead嘗試從yaml文件創建Pod,每個Wordpress教程。這裏的YAML:
metadata:
name: ghost
labels:
name: ghost
spec:
containers:
- image: us.gcr.io/my_project_id/my-ghost-blog
name: ghost
env:
- name: NODE_ENV
value: production
- name: VIRTUAL_HOST
value: myghostblog.com
ports:
- containerPort: 2368
當我運行kubectl create -f ghost.yaml
,創建吊艙,但從來沒有準備好:
> kubectl get pod ghost
NAME READY STATUS RESTARTS AGE
ghost 0/1 Running 11 3m
的艙不斷重新啓動,由kubectl describe pod ghost
輸出證實:

如果我不殺死吊艙,創建/啓動的這個循環會永遠持續下去。與成功的pod唯一的區別是缺少複製控制器。我不指望這是問題,因爲本教程沒有提及rc。
這是怎麼發生的?我怎樣才能從配置文件創建一個成功的pod?我在哪裏可以找到關於發生什麼的更詳細的日誌?
