kubectl-cost usage

kubectl cost will need to be pointed at the OpenCost service. The below example assumes you followed

Potentially set an alias:

alias kcac='kubectl cost --service-port 9003 --service-name opencost --kubecost-namespace opencost --allocation-path /allocation/compute'

Find the cost of each namespace based on the last five days:

kubectl cost --service-port 9003 --service-name opencost --kubecost-namespace opencost --allocation-path /allocation/compute  \
namespace \
--historical \
--window 5d \
--show-cpu \
--show-memory \
--show-pv \

Find the total projected monthly costs based on the last two hours:

kubectl cost --service-port 9003 --service-name opencost --kubecost-namespace opencost --allocation-path /allocation/compute  \
namespace \
--window 2h \

Using the alias, show the total costs of all resources with the label app:

Note: Unallocated represents resources not using the label

kcac label --historical -l app --window 5d
