We try to support the various authentication strategies supported by
kubectl, in order to provide seamless integration with your local setup. Here are the different authentication strategies we support, depending on how you’re using Kubebox:
Executable
Docker
Online
OpenID Connect
✔️
✔️
Amazon EKS
✔️
Digital Ocean
✔️
Google Kubernetes Engine
✔️
If the mode you’re using isn’t supported, you can refresh the authentication token/certs manually and update your kubeconfig file accordingly.
You can change the default
--storage_durationand--housekeeping_intervaloptions, added to the cAdvisor container arguments declared in thecadvisor.yamlfile, to adjust the duration of the storage moving window (default to5m0s), and the sampling period (default to10s) respectively. You may also have to provide the path of your cluster container runtime socket, in case it’s not following the usual convention.
Resources usage metrics are unavailable!
The metrics are retrieved from the REST API, of the cAdvisor pod running on the same node as the container for which the metrics are being requested. That REST API is accessed via the API server proxy, which requires proper RBAC permission, e.g.:
Kubernetes Operational View?
Goal: provide a common operational picture for multiple Kubernetes clusters.
Render nodes and indicate their overall status ("Ready")
Show node capacity and resource usage (CPU, memory)
Render one "box" per CPU and fill up to sum of pod CPU requests/usage
Render vertical bar for total memory and fill up to sum of pod memory requests/usage
Render individual pods
Indicate pod status by border line color (green: ready/running, yellow: pending, red: error etc)
Show current CPU/memory usage (gathered from Heapster) by small vertical bars
System pods ("kube-system" namespace) will be grouped together at the bottom
Provide tooltip information for nodes and pods
Animate pod creation and termination
What it is not:
It's not a monitoring solution. Use your preferred monitoring system to alert on production issues.
It's not a operation management tool. Kubernetes Operational View does not allow interacting with the actual cluster.

The app can be started in "mock mode" to work on UI features without running any Kubernetes cluster:
The provided
Makefilewill generate a Docker image by default:
Multiple clusters are supported by passing a list of API servers, reading a kubeconfig file or pointing to an HTTP Cluster Registry endpoint.
The following environment variables are supported:
AUTHORIZE_URLOptional OAuth 2 authorization endpoint URL for protecting the UI.
ACCESS_TOKEN_URLOptional token endpoint URL for the OAuth 2 Authorization Code Grant flow.
SCOPEOptional scope specifies level of access that the application is requesting.
CLUSTERSComma separated list of Kubernetes API server URLs. It defaults to
http://localhost:8001/(default endpoint ofkubectl proxy).CLUSTER_REGISTRY_URLURL to cluster registry returning list of Kubernetes clusters.
CREDENTIALS_DIRDirectory to read (OAuth) credentials from --- these credentials are only used for non-localhost cluster URLs.
DEBUGSet to "true" for local development to reload code changes.
KUBECONFIG_PATHPath to kubeconfig file to use for cluster access.
KUBECONFIG_CONTEXTSComma separated list of contexts to use when reading the kubeconfig file from
KUBECONFIG_PATH.MOCKSet to "true" to mock Kubernetes cluster data.
QUERY_INTERVALInterval in seconds for querying clusters (default: 5). Each cluster will at most queried once per configured interval.
REDIS_URLOptional Redis server to use for pub/sub events and job locking when running more than one replica. Example:
redis://my-redis:6379SERVER_PORTHTTP port to listen on. It defaults to
8080.NODE_LINK_URL_TEMPLATEThe URL prefix under which kube-ops-view is externally reachable (for example, if kube-ops-view is served via a reverse proxy). Used for generating relative and absolute links back to kube-ops-view itself. If the URL has a path portion, it will be used to prefix all HTTP endpoints served by kube-ops-view. If omitted, relevant URL components will be derived automatically.
The UI uses WebGL, ECMAScript 6, and EventSource features. The following browsers are known to work:
Chrome/Chromium 53.0+
Mozilla Firefox 49.0+

Weave Scope automatically generates a map of your application, enabling you to intuitively understand, monitor, and control your containerized, microservices-based application.
Ensure your computer is behind a firewall that blocks.
Understand your Docker containers in real timeChoose an overview of your container infrastructure, or focus on a specific microservice. Easily identify and correct issues to ensure the stability and performance of your containerized applications.
Contextual details and deep linkingView contextual metrics, tags, and metadata for your containers. Effortlessly navigate between processes inside your container to hosts your containers run on, arranged in expandable, sortable tables. Easily find the container using the most CPU or memory for a given host or service.
Interact with and manage containersInteract with your containers directly: pause, restart, and stop containers. Launch a command line. All without leaving the scope browser window.
Extend and customize via plugins

Kubebox relies on to retrieve the resource usage metrics. Before version 0.8.0, Kubebox used to access the cAdvisor endpoints, that are embedded in the Kubelet. However, these endpoints are being deprecated, and will eventually be removed, as discussed in .
Starting version 0.8.0, Kubebox expects cAdvisor to be deployed as a . This can be achieved with:
It’s recommended to use the provided cadvisor.yaml file, that’s tested to work with Kubebox. However, the DaemonSet example, from the project, should also work just fine. Note that the cAdvisor containers must run with a privileged security context, so that they can access the container runtime on each node.
Starting version 0.8.0, Kubebox expects to be deployed as a DaemonSet. See the section for more details;
It's not a replacement for the . The Kubernetes Dashboard is a general purpose UI which allows managing applications.

Template to make Pods clickable, e.g. can point to . {cluster} (cluster ID), {namespace} (Pod's namespace), and {name} (Pod name) will be replaced in the URL template.ROUTE_PREFIX
