#  minikube start --cpus 4 --memory 8192 --disk-size 60g
# helm init

Download the prometheus-operator from the official github repository, use dependency update for updating the dependency locally:

# cd prometheus-operator
# helm dependency update

Record the docker images before deployment:

# eval $(minikube docker-env)
# docker images>before.txt

#  helm install --name newprom .

# docker images>after.txt
