我试图使用Helm图表安装KeyCloak,所以我运行了这两个命令。
$ helm install codecentric/keycloak
$ helm install keycloak codecentric/keycloak
然后我检查了吊舱状态:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
keycloak-0 0/1 ImagePullBackOff 0 52s
由于出现错误,我检查了详细的事件:

为什么不能成功拉出图像?
答案 0 :(得分:2)
正如评论所暗示的,这似乎是与防火墙相关的问题。我刚刚在本地minikube实例上运行了相同的命令,效果很好。
您的集群可以从dockerhub中提取其他图像吗?
您可以使用ssh进入任何工作节点,并尝试使用docker pull
进行查找。
