Question

我已经安装了Kubernetes仪表板，并创建了具有适当权限的服务帐户用户，但是由于某些原因，使用令牌登录失败。

我看到以下日志：

floreks在GitHub上写道：

注意：仪表板不应通过HTTP公开公开。对于通过HTTP访问的域，将无法登录。单击登录页面上的“登录”按钮后，什么也不会发生。

另外，正如chrissound写道：

我通过为仪表板用户授予集群管理员权限并在登录提示符下单击“跳过”来解决此问题：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
    <sub-deployment name="pfi-web.war">
        <exclusions>
            <module name="org.apache.commons.logging" />
            <module name="org.apache.log4j" />
            <module name="org.jboss.logging" />
            <module name="org.jboss.logging.jul-to-slf4j-stub" />
            <module name="org.jboss.logmanager" />
            <module name="org.jboss.logmanager.log4j" />
            <module name="org.slf4j" />
            <module name="org.slf4j.impl" />
        </exclusions>
    </sub-deployment>
</jboss-deployment-structure>

Answer 2

注意：不应使用kubectl proxy命令公开显示控制板，因为它仅允许HTTP连接。对于除localhost和127.0.0.1之外的域，将无法登录。单击登录页面上的“登录”按钮后，什么也不会发生。

您可以将服务kubernetes-dashboard更改和发布为NodePort类型，然后使用指定的NodePort访问仪表板。例如：

---
# ------------------- Dashboard Service ------------------- #

kind: Service
apiVersion: v1
metadata:
  labels:
    k8s-app: kubernetes-dashboard
    kubernetes.io/cluster-service: "true"
  name: kubernetes-dashboard
  namespace: kube-system
spec:
  type: NodePort
  ports:
    - port: 443
      targetPort: 8443
      nodePort: 31115
  selector:
    k8s-app: kubernetes-dashboard

无法使用令牌和服务帐户登录Kubernetes仪表板
