# A Service gives a stable way to reach a set of Pods, even as individual
|
||
|
|
# Pods are created and destroyed and get new internal IP addresses over
|
||
|
|
# time. This Service selects any Pod labelled app: demo (see
|
||
|
|
# deployment.yaml) and forwards traffic to it.
|
||
|
|
#
|
||
|
|
# type: LoadBalancer asks the cluster for a real, dedicated IP address that
|
||
|
|
# anything on your network can reach directly. On a cloud provider that
|
||
|
|
# would provision an actual cloud load balancer; on bare metal there's
|
||
|
|
# nothing to provision it, which is exactly the gap MetalLB
|
||
|
|
# (apps/metallb.yaml) fills — it watches for LoadBalancer Services and
|
||
|
|
# hands them an address from the pool configured in
|
||
|
|
# apps/metallb/templates/ipaddresspool.yaml. Until that pool exists, this
|
||
|
|
# Service's address will show as <pending>; see docs/05-metallb.md.
