Instructions

# Start minikube
minikube start --cpus=8 --memory=11000 --disk-size=50g --kubernetes-version=v1.19.5

# Install Operator
kubectl apply -f operator.yaml

# Bring up initial cluster and commerce keyspace
# NOTE: If you are using MySQL 8, update the images section to use mysql80 images
# Example:
#  images:
#    vtctld: vitess/lite:mysql80
#    vtadmin: vitess/vtadmin:latest
#    vtgate: vitess/lite:mysql80
#    vttablet: vitess/lite:mysql80
#    vtbackup: vitess/lite:mysql80
#    vtorc: vitess/lite:mysql80
#    mysqld:
#      mysql80Compatible: vitess/lite:mysql80

kubectl apply -f 101_initial_cluster.yaml

# Port-forward vtctld, vtgate and vtadmin and apply schema and vschema
# VTAdmin's UI will be available at http://localhost:14000/
