Deploying onos-cli with Helm
This guide deploys
onos-cli through it's Helm chart assumes you have a Kubernetes cluster running with an atomix controller deployed in a namespace.
onos-cli Helm chart is based on Helm 3.0 version, with no need for the Tiller pod to be present. If you don't have a cluster running and want to try on your local machine please follow first the Kubernetes setup steps outlined in deploy with Helm. The following steps assume you have the setup outlined in that page, including the
micro-onos namespace configured.
Installing the Chart
To install the chart in the
micro-onos namespace run from the root directory of the
onos-helm-charts repo the command:
helm install -n micro-onos onos-cli onos-cli
The output should be:
NAME: onos-cli LAST DEPLOYED: Tue Nov 26 13:31:42 2019 NAMESPACE: default STATUS: deployed REVISION: 1 TEST SUITE: None
helm install assigns a unique name to the chart and displays all the k8s resources that were created by it. To list the charts that are installed and view their statuses, run
helm ls NAME REVISION UPDATED STATUS CHART APP VERSION NAMESPACE ... onos-cli 1 Tue May 14 18:56:39 2019 DEPLOYED onos-cli-0.0.1 0.0.1 default
Installing the chart in a different namespace.
helm install command substituting
micro-onos with your namespace.
helm install -n <your_name_space> onos-cli onos-cli
Installing the chart with debug.
onos-cli offers the capability to open a debug port (4000) to the image. To enable the debug capabilities please set the debug flag to true in
values.yaml or pass it to
helm install -n micro-onos onos-cli onos-cli --set debug=true
If your chart does not install or the pod is not running for some reason and/or you modified values Helm offers two flags to help you debug your chart:
--dry-runcheck the chart without actually installing the pod.
--debugprints out more information about your chart
helm install -n micro-onos onos-cli --debug --dry-run onos-cli/
Also to verify how template values are expanded, run:
helm install template onos-gui
Uninstalling the chart.
To remove the
onos-cli pod issue
helm delete -n micro-onos onos-cli
To view the pods that are deployed, run
kubectl -n micro-onos get pods.
Getting access to the onos-cli console
To gain acess to the
onos-cli console and be able of issuing the different cli commands the following command is need:
kubectl -n micro-onos exec -it $(kubectl -n micro-onos get pods -l type=cli -o name) -- /bin/sh
At this point you can execute
config and all the other commands. For example:
onos topo get devices
