Cloudbuild Private pool doesn't show correct IP

[semicircle]

We're trying to have cloud build launch instances in a private pool but we're not seeing the correct IPs on the workers.

We configured a /24 block of IPs which is connected via private services access. 

However, launching a worker and running an ifconfig -a on the worker shows an internal IP address of 192.168.10.x

Here's the trigger yaml file that we're testing this with which returns

inet addr:192.168.10.2 Bcast:192.168.10.255

steps:

  - name: bash

    args:

      - echo

      - I am running in a private pool!

  - name: bash

    args:

      - '-c'

      - |

        ifconfig -a

    entrypoint: bash

timeout: 3600s

options:

  logging: CLOUD_LOGGING_ONLY

  dynamicSubstitutions: true

  pool:

    name: projects/$PROJECT_ID/locations/europe-west3/workerPools/cicd-private-pool

Shouldn't we be seeing an IP address from the cicd-private-pool /24 ?
