Usage

Kubescope CLI can be used in Kubernetes or locally because it connects to the docker socket to collect stats.

Kubernetes

Kubescope needs access to the docker socket on the host, stdin and a tty. It also needs to be running on the same host that you want to monitor. Here's an example pod spec:

apiVersion: v1
kind: Pod
metadata:
  name: kubescope-cli-example
spec:
  containers:
  - image: hharnisc/kube-scope-cli:9c02f636b8cb6d4f251af3e73d19248c2a31b3e1
    name: kubescope-cli-example
    stdin: true
    tty: true
    volumeMounts:
    - mountPath: /var/run/docker.sock
      name: docker-sock-volume
    env:
    - name: MATCH_NAME
      value: ".*my-app.*"
    - name: SKIP_NAME
      value: ".*POD.*"
    # - name: MATCH_IMAGE
    #   value: ".*my-image.*"
    # - name: SKIP_IMAGE
    #   value: ".*some-image.*"
    # - name: DOCKER_SOCKET
    #   value: /var/run/docker.sock
  volumes:
  - name: docker-sock-volume
    hostPath:
      path: /var/run/docker.sock
  # pin kubescope to a specific node
  # nodeSelector:
    # kubernetes.io/hostname: minikube

Attach to the running container:

kubectl attach -it kubescope-cli-example

Locally

Kubescope CLI can be used locally and connects to the docker socket to collect stats

MATCH_NAME=.*my_app.* npm start
