Command line interface

The storageos command line interface (CLI) is used to manage cluster-wide configuration.

It is highly recommended to install the CLI, since it can be used to generate a lot of useful information about your Ondat cluster and significantly speed up resolution times for support issues.

Installation

# linux/amd64
curl -sSLo storageos \ 
    https://github.com/storageos/go-cli/releases/download/v2.4.4/storageos_linux_amd64 \
    && chmod +x storageos \
    && sudo mv storageos /usr/local/bin/

# MacOS
curl -sSLo storageos \
    https://github.com/storageos/go-cli/releases/download/v2.4.4/storageos_darwin_amd64 \
    && chmod +x storageos \
    && sudo mv storageos /usr/local/bin/

You will need to provide the correct credentials to connect to the API. The default installation uses the storageos-api Secret to generate the first admin user. By default, it creates a single user with username storageos and password storageos:

export STORAGEOS_USERNAME=storageos
export STORAGEOS_PASSWORD=storageos
export STORAGEOS_ENDPOINTS=10.1.5.249:5705

Run the CLI as a deployment in your cluster

This is a preferred installation method, since our support bundle generation software can automatically detect a deployment called “cli” and warn you if you do not have the CLI installed. You can run CLI commands with kubectl exec on your cli container.

kubectl apply -f the below YAML manifest to install.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: cli
  namespace: kube-system
  labels:
    app: storageos-cli
    kind: storageos
    app.kubernetes.io/part-of: storageos
    app.kubernetes.io/component: storageos-cli
spec:
  replicas: 1
  selector:
    matchLabels:

        command:
          - "/bin/sh"
          - "-c"
          - "while true; do sleep 3600; done"
        imagePullPolicy: IfNotPresent
        name: cli
        ports:
        - containerPort: 5705
        env:
        - name: STORAGEOS_USERNAME
          value: storageos
        - name: STORAGEOS_PASSWORD
          value: storageos
        - name: STORAGEOS_ENDPOINTS
          value: storageos:5705
      restartPolicy: Always

Run CLI as a container

You can also run the cli as a container in your Kubernetes cluster. Then exec into it to run commands.

kubectl -n kube-system run \
    --image storageos/cli:v2.4.4 \
    --restart=Never                          \
    --env STORAGEOS_ENDPOINTS=storageos:5705 \
    --env STORAGEOS_USERNAME=storageos       \
    --env STORAGEOS_PASSWORD=storageos       \
    --command cli                            \
    -- /bin/sh -c "while true; do sleep 100000; done"
