How we added/built stand-alone tests for Kubecost

• git clone
• mkdir/kubecost
• cd kubecost/
• go mod init github.com/aws/aws-k8s-tester/k8s-tester/kubecost
• Create a file to implement the Tester Interface. touch tester.go
• copy a vend file from another package cp ../vend.sh .
• Write tests
• run ./vend.sh
• run go mod tidy -v

Test/Run singe test stand-alone

go run cmd/k8s-tester-kubecost/main.go apply \
    --kubectl-path="/usr/local/bin/kubectl" \
    --kubeconfig-path="/Users/Username/.kube/config" \
    --log-outputs="kubecost.log"


## Delete
go run cmd/k8s-tester-kubecost/main.go delete \
    --kubectl-path="/usr/local/bin/kubectl" \
    --kubeconfig-path="/Users/Username/.kube/config" \
    --log-outputs="kubecost.log"

This test is equivilant to running this set of commands

kubectl create namespace kubecost helm repo add https://kubecost.github.io/cost-analyzer/ helm install kubecost cost-analyzer --namespace kubecost --set --set persistentVolume.enabled="false" --set prometheus.server.persistentVolume.enabled=false

After running apply how to check kubecost

kubectl port-forward --namespace kubecost deployment/cost-analyzer 9090
