我正在尝试将我的maven集成测试迁移到bazel. 在运行时我面临一些问题。为了调试，我想maven dependency:tree与 bazel 的依赖树进行比较。以避免任何额外的依赖项或检测我是否缺少某些依赖项。

我们如何比较这些依赖关系（mavenvs bazel）。有没有办法获取 bazel 目标的依赖树？

我正在尝试使用https://kubernetes.io/blog/2018/04/13/local-persistent-volumes-beta/中提到的本地持久卷来创建我的statefulset pod.但当我的pod尝试声明音量时.我收到以下错误:

Events:
  Type     Reason            Age                 From               Message
  ----     ------            ----                ----               -------
  Warning  FailedScheduling  4s (x243 over 20m)  default-scheduler  0/2 nodes are available: 1 node(s) didn't find available persistent volumes to bind, 1 node(s) had taints that the pod didn't tolerate.

以下是我创建的存储类和持久卷:

storageclass - 卡夫卡broker.yml

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: kafka-broker
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

storageclass - 卡夫卡zookeeper.yml

kind: StorageClass
apiVersion: storage.k8s.io/v1

volumeBindingMode: WaitForFirstConsumer

PV-zookeeper.yml

apiVersion: v1
kind: PersistentVolume

在初始化时,kubeadm我遇到了以下错误.kubeadm reset在做之前我也尝试过命令kubadm init.Kubelet也在运行,我用过的命令也是如此systemctl enable kubelet && systemctl start kubelet.以下是执行kubeadm init后的日志

我尝试使用命令运行我的应用程序服务docker stack deploy。使用此命令我收到以下错误：

"starting container failed: error creating external connectivity network: cannot restrict inter-container communication: please ensure that br_netfilter kernel module is loaded"

我的服务的 Docker-compose 文件如下，它只包含一项服务：

version: '3.1'

services:
  app_service:
    image: app-image:latest

但是，如果我尝试使用 simple 来运行此服务docker run app-image:latest，那么它会正确运行。这里可能有什么问题？

以下是输出docker info：

之间有什么区别gevent.sleep()和time.sleep()在Python？什么时候gevent.sleep()和time.sleep()？

在Apache Ignite中的网格中连接2个节点时出现以下错误。当我在两个节点上运行脚本ignite.sh时，这两个节点会自我检测。但是，当我尝试使用ignite.sh在一个节点上以及使用Java代码在另一个节点上启动ignit时，出现以下错误。
