     - name: bo1-ome
           uri: https://10.10.100.23:443
           public_addr: "bo1-ome.teleport.bo1.dfinity.network"
           insecure_skip_verify: true
           rewrite:
             redirect:
             - "10.10.100.23"
             - "bo1-ome.teleport.bo1.dfinity.network"
           labels:
             dc: "bo1"
