  ## Lab
  
+ ### Mac / Windows
+ 
+ You'll need to know the IP of the `docker-machine` vm that is your docker host:
+ 
+ ```
+ docker-machine ip $(docker-machine active)
+ ```
+ 
+ Use this when browsing to a node IP in place of `localhost` below.
  
  ### Pods

  ### Service
  
  To access Lobsters from outside the cluster, we'll need a service. The
! service defined in [service.yaml](service.yaml) will route traffic to
! any pod with the label `app: lobsters`, which matches our pod
! definition. The service is for port 80, but routes to the port labeled
! `web` in our pod definition. The `type: LoadBalancer` creates an IP
! external to the cluster in supported environments.
  
  Create the service and pod:
  
  ```
! kubectl create -f ./service.yaml,./pod.yaml
  ```
  
  ```

  ### Service
  
  To access Lobsters from outside the cluster, we'll need a service. The
! service defined in [service-local.yaml](service-local.yaml) will route
! traffic to any pod with the label `app: lobsters`, which matches our
! pod definition. The service routs to the port labeled `web` in our pod
! definition. The `type: NodePort` line allows traffic on a particular
! port of each node to be routed to the service.
  
  Create the service and pod:
  
  ```
! kubectl create -f ./service-local.yaml,./pod.yaml
  ```
