Purser Plugin Usage

Once installed, Purser is ready for use right away. You can query using native Kubernetes grouping artifacts.

Purser supports the following list of commands.

# query cluster visibility in terms of savings and summary for the application.
kubectl plugin purser get [summary|savings]

# query resources filtered by associated namespace, labels and groups.
kubectl plugin purser get resources group <group-name>

# query cost filtered by associated labels, pods and node.
kubectl plugin purser get cost label <key=val>
kubectl plugin purser get cost pod <pod name>
kubectl plugin purser get cost node all

# configure user-costs for the choice of deployment.
kubectl plugin purser [set|get] user-costs

Use flag --kubeconfig=<absolute path to config> if your cluster configuration is not at the default location.

         Total cost:                 7140.27$

  2. Get Cost Of All Nodes

    kubectl purser get cost node all

  3. Get Savings

    $ kubectl plugin purser get savings

Next, define higher level groupings to define your business, logical or application constructs.
