In this directory, you will see a group of yaml files. The first digit of each file name indicates the phase of example. The next two digits indicate the order in which to execute them. For example, 101_initial_cluster.yaml is the first file of the first phase. We shall execute that now:
kubectl apply -f 101_initial_cluster.yaml
We have supplied an example yaml for bringing up Vitess with the experimental vtorc component. You can try this out by using the following command: kubectl apply -f vtorc_example.yaml. Once vtorc is officially released, the examples will be updated accordingly.
The port-forward will only forward to a specific pod. Currently, kubectl does not automatically terminate a port-forward as the pod disappears due to apply/upgrade operations. You will need to manually restart the port-forward.
For ease-of-use, Vitess provides a script to port-forward from Kubernetes to your local machine. This script also recommends setting up aliases for mysql and vtctlclient:
You should now be able to connect to the VTGate Server in your cluster with the MySQL client:

In this example, we deployed a single unsharded keyspace named commerce. Unsharded keyspaces have a single shard named 0. The following schema reflects a common ecommerce scenario that was created by the script:
