wlan-cloud-helm

This repository contains helm charts for various deployment types of the tip wlan cloud services.

Deploying the wlan-cloud deployment

• Run the following command under tip-wlan-helm directory:

  • helm install <RELEASE_NAME> tip-wlan/ -n default -f tip-wlan/resources/environments/dev.yaml

  More details can be found here: https://telecominfraproject.atlassian.net/wiki/spaces/WIFI/pages/262176803/Pre-requisites+before+deploying+Tip-Wlan+solution

Deleting the wlan-cloud deployment:

• Run the following command:

  • helm del tip-wlan -n default

  (Note: this would not delete the tip namespace and any PVC/PV/Endpoints under this namespace. These are needed so we can reuse the same PVC mount when the pods are restarted.)

  To get rid of them (PVC/PV/Endpoints), you can use the following script (expects that you are in the tip namespace or add -n tip to the below set of commands):

  #!/bin/bash
  # Usage: ./cleanup-pvc-gluster-resources.sh <namespace to delete>
  # script to remove gluster-dynamic-endpointsm, gluster-dynamic-svc and pvc that are retained after
  # helm del of the release.
  # NOTE: we are not deleting the namespace, to avoid deletion of any resource by mistake.
  kubectl get endpoints --no-headers -o custom-columns=":metadata.name"  | xargs kubectl delete endpoints
  kubectl get svc --no-headers -o custom-columns=":metadata.name"  | xargs kubectl delete svc
  kubectl get pvc --no-headers -o custom-columns=":metadata.name"  | xargs kubectl delete pvc
  kubectl get pv --no-headers -o custom-columns=":metadata.name"  | xargs kubectl delete pv
  

Running tests under wlan-cloud deployment

Currently we have tests for:

• Cassandra: Test that verifies the following in a running Cassandra cluster:

  • Keyspace, Table creation
  • Insert a record in the Table
  • Select the record
  • Delete Table
  • Delete Keyspace (to enable us to run the test again)
    • NOTE: For the test to work, make sure that the cluster-size remains the same, if you are redeploying the chart using helm-del and helm-install with existing pvc.

• Kafka: Test that verifies:

  • Creating a topic
  • Posting a message on topic
  • Consuming a message from topic
  • Changing the retention period of a topic to 1 sec
  • Marking the topic for deletion (to enable us to run the test again)

• Run the following command under tip-wlan-helm directory after the components are running:

  • helm test <RELEASE_NAME> -n default (For more details add --debug flag to the above command)
