Document how to use Scope in multi-cluster environment

[sachinar]

Hi Team,

We are having multiple kubernetes clusters & we need to monitor them using weave scope.

How we can setup centralize dashboard. for multiple clusters?

Hi @sachinar, thanks for bringing this up!

As of now, Scope can work with multiple clusters (#3359), but the UI doesn't always know which objects come from which cluster (#2199).

I'll keep this issue open as I think we should add some minimal documentation in the FAQ, but in the meantime, all you need to do to get you going is to install Scope probe on every host of every cluster you are running and point them all to the same Scope app endpoint.

Please take a look at the following links for more context / examples:

• https://www.weave.works/docs/scope/latest/how-it-works/
• https://github.com/weaveworks/scope/tree/master/examples/k8s

node with app

version: '2'
services:
  scope-app:
    image: weaveworks/scope:latest
    container_name: scope-app
    restart: unless-stopped
    network_mode: host
    pid: host
    privileged: true
    volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - /var/run/scope/plugins:/var/run/scope/plugins
    - /sys/kernel/debug:/sys/kernel/debug
    command:
    - '--no-probe'
  scope-probe:
    image: weaveworks/scope:latest
    container_name: scope-probe
    restart: unless-stopped
    network_mode: host
    pid: host
    privileged: true
    volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - /var/run/scope/plugins:/var/run/scope/plugins
    - /sys/kernel/debug:/sys/kernel/debug
    command:
    - '--probe.docker=true'
    - 'scope-app:4040'`

node with prober

version: '2'
services:
  scope-probe:
    image: weaveworks/scope:latest
    container_name: scope-probe
    restart: unless-stopped
    network_mode: host
    pid: host
    privileged: true
    volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - /var/run/scope/plugins:/var/run/scope/plugins
    - /sys/kernel/debug:/sys/kernel/debug
    command:
    - '--probe.docker=true'
    - 'IP-of-app-node:4040'

and it work's perfect
