#### Network Load Balancer support on AWS [alpha]
|
||||
|
||||
**Warning:** This is an alpha feature and not recommended for production clusters yet.
|
||||
|
||||
Starting in version 1.9.0, Kubernetes supports Network Load Balancer (NLB). To
|
||||
use a Network Load Balancer on AWS, use the annotation `service.beta.kubernetes.io/aws-load-balancer-type`
|
||||
with the value set to `nlb`.
|
||||
|
||||
```yaml
|
||||
metadata:
|
||||
name: my-service
|
||||
annotations:
|
||||
service.beta.kubernetes.io/aws-load-balancer-type: "nlb"
|
||||
```
|
||||
|
||||
Unlike classic Elastic Load Balancers, Network Load Balancers (NLBs) forward the
|
||||
client's IP through to the node. If a service's `spec.externalTrafficPolicy` is
|
||||
set to `Cluster`, the client's IP address will not be propagated to the end
|
||||
pods.
|
||||
|
||||
By setting `spec.externalTrafficPolicy` to `Local`, client IP addresses will be
|
||||
propagated to the end pods, but this could result in uneven distribution of
|
||||
traffic. Nodes without any pods for a particular LoadBalancer service will fail
|
||||
the NLB Target Group's health check on the auto-assigned
|
||||
`spec.healthCheckNodePort` and not recieve any traffic.
|
||||
|
||||
In order to achieve even traffic, either use a DaemonSet, or specify a
|
||||
[pod anti-affinity](/docs/concepts/configuration/assign-pod-node/#inter-pod-affinity-and-anti-affinity-beta-feature)
|
||||
to not locate pods on the same node.
|
||||
|
||||
NLB can also be used with the [internal load balancer](/docs/concepts/services-networking/service/#internal-load-balancer)
|
||||
annotation.
|
||||
|
||||
In order for client traffic to reach instances behind an NLB, the Node security
|
||||
groups are modified with the following IP rules:
|
||||
|
||||
| Rule | Protocol | Port(s) | IpRange(s) | IpRange Description |
|
||||
|------|----------|---------|------------|---------------------|
|
||||
| Health Check | TCP | NodePort(s) (`spec.healthCheckNodePort` for `spec.externalTrafficPolicy = Local`) | VPC CIDR | kubernetes.io/rule/nlb/health=\<loadBalancerName\> |
|
||||
| Client Traffic | TCP | NodePort(s) | `spec.loadBalancerSourceRanges` (defaults to `0.0.0.0/0`) | kubernetes.io/rule/nlb/client=\<loadBalancerName\> |
|
||||
| MTU Discovery | ICMP | 3,4 | `spec.loadBalancerSourceRanges` (defaults to `0.0.0.0/0`) | kubernetes.io/rule/nlb/mtu=\<loadBalancerName\> |
|
||||
|
||||
Be aware that if `spec.loadBalancerSourceRanges` is not set, Kubernetes will
|
||||
allow traffic from `0.0.0.0/0` to the Node Security Group(s). If nodes have
|
||||
public IP addresses, be aware that non-NLB traffic can also reach all instances
|
||||
in those modified security groups. IPv6 is not yet supported for source ranges.
|
||||
|
||||
In order to limit which client IP's can access the Network Load Balancer,
|
||||
specify `loadBalancerSourceRanges`.
|
||||
|
||||
```yaml
|
||||
spec:
|
||||
loadBalancerSourceRanges:
|
||||
- "143.231.0.0/16"
|
||||
```
|
||||
|
||||
**Note:** NLB only works with certain instance classes, see the [AWS documentation](http://docs.aws.amazon.com/elasticloadbalancing/latest/network/target-group-register-targets.html#register-deregister-targets)
|
||||
for supported instance types.
