在Kubernetes上安装Kamel时，我必须通过什么注册表

Question

我已经在AWS EC2实例中安装了Kubernetes。我不使用任何Minikube或OpenShift。我正在尝试在Kubernetes顶部安装Kamel来运行我的集成代码。当我尝试运行kamel install命令以下命令以下错误时，

Error: cannot find automatically a registry where to push images

当我尝试以root用户为单位以下错误的抛出以下错误时，

Error: cannot get current namespace: open /root/.kube/config: no such file or directory

我想知道在运行kamel install命令时必须通过的注册表。我有一个带有演示存储库的Docker Hub帐户。我应该通过吗？

kamel install --registry hubusername/reponame

通过价值之后，我没有得到的是，我要低于成功消息，

Camel K installed in namespace default

当我尝试运行一个示例式脚本脚本时，它在以下消息后被绞死

kamel run hello.groovy --dev

您能在这里帮我吗？谢谢您的宝贵时间。

如果安装了单个节点kubernetes机会是您唯一的节点是主节点。这就是为什么Kubernetes不会安排您的工作。通过运行：

来检查一下

kubectl get node

如果您唯一的节点在其角色列中显示"主" - 您需要取消它以允许安排：

kubectl taint nodes --all node-role.kubernetes.io/master-

尝试重新运行您的kamel工作。
