How to select a specific physical location

Our clusters extends to multiple locations in NYU. If you want, you can choose to have your workloads run in specific buildings by adding a nodeSelector to your workloads with the label topology.kubernetes.io/zone.

For example:

apiVersion: v1
kind: Pod
metadata:
  name: edge-compute
spec:
  containers:
    - name: python:3.10
  nodeSelector:
    topology.kubernetes.io/zone: "wwh"

Another option is nodeAffinity, which is more verbose but a little more powerful:

apiVersion: v1
kind: Pod
metadata:
  name: edge-compute
spec:
  containers:
    - name: python:3.10
  affinity:
    nodeAffinity:
      # Prefer running in 60fifthave
      preferredDuringSchedulingIgnoredDuringExecution
        - weight: 1
          preference:
            matchExpressions:
              - key: topology.kubernetes.io/zone
                operator: In
                values:
                  - "60fifthave"
      # Only run in either 60fifthave or 7e12
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
          - matchExpressions:
              - key: topology.kubernetes.io/zone
                operator: In
                values:
                  - "60fifthave"
                  - "7e12"

The zones available for your use are:

rcdc 16 Data Center in Secaucus New Jersey
7e12 4 7 East 12th St (Union Square)
60fifthave 3 60 Fifth Ave (Union Square)

Make sure to use quotes around 7e12

If you put 7e12 in YAML, it will be recognized as the number 7000000000000.0.

You need to put quotes around it: "7e12"
