Kubernetes容器挂在ContainerCreating上

我已经创build了一个我知道可用的容器，并且已经在一个“只有主人”的Kubernetes上进行了testing。 我现在想要在一个奴隶上运行pod。 我已经使用kubeadm init出一个集群，并且kubeadm join <IP>:6443 --discovery-token-unsafe-skip-ca-verification --token XXXXXXjoin一个从VM。 尝试从以下YAML创build一个吊舱时吊舱挂在ContainerCreating：

 apiVersion: apps/v1beta1 kind: StatefulSet metadata: name: psql spec: serviceName: "psql-svc" replicas: 3 template: metadata: labels: app: psqllogical spec: terminationGracePeriodSeconds: 10 containers: - name: psqllogical image: psqllogical:v1 imagePullPolicy: Never ports: - containerPort: 5432 name: dbport volumeMounts: - name: db mountPath: /var/lib/postgresql/data volumeClaimTemplates: - metadata: name: db spec: accessModes: [ "ReadWriteOnce" ] storageClassName: psql-pv resources: requests: storage: 100Mi 

该图像是本地存储的，并成功地在单个主机上build立。 还有其他的YAML（PV，一些服务）。

kubectl describe pod POD_NAME回应：

kubectl logs psql-0 ：

 Error from server (BadRequest): container "psqllogical" in pod "psql-0" is waiting to start: ContainerCreating 

kubectl describe node <SlaveIP>报告有足够的资源，据说就绪。

这两个虚拟机都运行CentOS 7，K8s版本1.85，Docker版本1.12.6。 我已经testing过，这也发生在其他的Docker镜像上，而不仅仅是我自定义的postgres镜像。 虚拟机由Openstackpipe理。

我做了以下：

• 确保港口是开放的
• 确保selinux已禁用
• 与奴隶拼合
• 尝试了另外的Docker容器，它也挂在ContainerCreating上
• 确保psql YAML成功地在单个节点集群上工作
• 在主机和从机上构build自定义映像（如果需要，不确定）
