Explore Applications Running on Docker
To explore your app in Weave Cloud, run the following on all of your hosts:
sudo curl -L git.io/scope -o /usr/local/bin/scope
sudo chmod a+x /usr/local/bin/scope
scope launch --service-token=[cloud-token]
Where,
- [cloud-token] is the token you obtained from the instance settings page in Weave Cloud.
Visualize Weave Net Container Networking
To troubleshoot your Weave Net installation and visualize container networking in Weave Cloud run:
sudo curl -L git.io/weave -o /usr/local/bin/weave
sudo chmod a+x /usr/local/bin/weave
weave launch --token=[cloud-token]
Where,
- [cloud-token] is the token you obtained from the instance settings page in Weave Cloud.
Docker Compose
To start exploring your app in Docker decide on the Compose format version to use:
Docker Compose Format Version 1:
probe:
image: weaveworks/scope:1.3.0
net: "host"
pid: "host"
privileged: true
labels:
- "works.weave.role=system"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:rw"
command:
- "--probe.docker=true"
- "--service-token=${SCOPE_SERVICE_TOKEN}"
Docker Compose Format Version 2:
version: '2'
services:
probe:
image: weaveworks/scope:1.3.0
network_mode: "host"
pid: "host"
privileged: true
labels:
- "works.weave.role=system"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:rw"
command:
- "--probe.docker=true"
- "--service-token=${SCOPE_SERVICE_TOKEN}"
Version 2 of this YAML file supports a network mode that may be required with any Docker plugins that you are using. See Compose File Reference for more information.
And once you’ve set up a compose file, you can launch Scope (the Explore Agent) onto your local machine:
SCOPE_SERVICE_TOKEN=<token> docker-compose up -d
Where,
SCOPE_SERVICE_TOKEN=<token>is the token you obtained after you signed up for Weave Cloud.
Note: You must install launch Scope onto every node that you want to monitor.
Go to https://cloud.weave.works and click Explore or View Instance from the settings page in your instance.
