# NATS Server
|
||||||
|
|
||||||
|
[NATS](https://nats.io) is a simple, secure and performant communications system for digital systems, services and devices. NATS is part of the Cloud Native Computing Foundation ([CNCF](https://cncf.io)). NATS has over [30 client language implementations](https://nats.io/download/), and its server can run on-premise, in the cloud, at the edge, and even on a Raspberry Pi. NATS can secure and simplify design and operation of modern distributed systems.
|
||||||
|
|
||||||
|
## TL;DR;
|
||||||
|
|
||||||
|
```console
|
||||||
|
helm repo add nats https://nats-io.github.io/k8s/helm/charts/
|
||||||
|
helm install my-nats nats/nats
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
### Server Image
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
image: nats:2.1.7-alpine3.11
|
||||||
|
pullPolicy: IfNotPresent
|
||||||
|
```
|
||||||
|
|
||||||
|
### Limits
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
# The number of connect attempts against discovered routes.
|
||||||
|
connectRetries: 30
|
||||||
|
|
||||||
|
# How many seconds should pass before sending a PING
|
||||||
|
# to a client that has no activity.
|
||||||
|
pingInterval:
|
||||||
|
|
||||||
|
# Server settings.
|
||||||
|
limits:
|
||||||
|
maxConnections:
|
||||||
|
maxSubscriptions:
|
||||||
|
maxControlLine:
|
||||||
|
maxPayload:
|
||||||
|
|
||||||
|
writeDeadline:
|
||||||
|
maxPending:
|
||||||
|
maxPings:
|
||||||
|
lameDuckDuration:
|
||||||
|
|
||||||
|
# Number of seconds to wait for client connections to end after the pod termination is requested
|
||||||
|
terminationGracePeriodSeconds: 60
|
||||||
|
```
|
||||||
|
|
||||||
|
### Logging
|
||||||
|
|
||||||
|
*Note*: It is not recommended to enable trace or debug in production since enabling it will significantly degrade performance.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
logging:
|
||||||
|
debug:
|
||||||
|
trace:
|
||||||
|
logtime:
|
||||||
|
connectErrorReports:
|
||||||
|
reconnectErrorReports:
|
||||||
|
```
|
||||||
|
|
||||||
|
### TLS setup for client connections
|
||||||
|
|
||||||
|
You can find more on how to setup and trouble shoot TLS connnections at:
|
||||||
|
https://docs.nats.io/nats-server/configuration/securing_nats/tls
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
tls:
|
||||||
|
secret:
|
||||||
|
name: nats-client-tls
|
||||||
|
ca: "ca.crt"
|
||||||
|
cert: "tls.crt"
|
||||||
|
key: "tls.key"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Clustering
|
||||||
|
|
||||||
|
If clustering is enabled, then a 3-node cluster will be setup. More info at:
|
||||||
|
https://docs.nats.io/nats-server/configuration/clustering#nats-server-clustering
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
cluster:
|
||||||
|
enabled: true
|
||||||
|
replicas: 3
|
||||||
|
|
||||||
|
tls:
|
||||||
|
secret:
|
||||||
|
name: nats-server-tls
|
||||||
|
ca: "ca.crt"
|
||||||
|
cert: "tls.crt"
|
||||||
|
key: "tls.key"
|
||||||
|
```
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
```sh
|
||||||
|
$ helm install nats nats/nats --set cluster.enabled=true
|
||||||
|
```
|
||||||
|
|
||||||
|
## Leafnodes
|
||||||
|
|
||||||
|
Leafnode connections to extend a cluster. More info at:
|
||||||
|
https://docs.nats.io/nats-server/configuration/leafnodes
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
leafnodes:
|
||||||
|
enabled: true
|
||||||
|
remotes:
|
||||||
|
- url: "tls://connect.ngs.global:7422"

## Setting up External Access
|
||||||
|
|
||||||
|
### Using HostPorts
|
||||||
|
|
||||||
|
In case of both external access and advertisements being enabled, an
|
||||||
|
initializer container will be used to gather the public ips. This
|
||||||
|
container will required to have enough RBAC policy to be able to make a
|
||||||
|
look up of the public ip of the node where it is running.
|
||||||
|
|
||||||
|
For example, to setup external access for a cluster and advertise the public ip to clients:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
# Toggle whether to enable external access.
|
||||||
|
# This binds a host port for clients, gateways and leafnodes.
|
||||||
|
externalAccess: true
|
||||||
|
|
||||||
|
# Toggle to disable client advertisements (connect_urls),
|
||||||
|
# in case of running behind a load balancer (which is not recommended)
|
||||||
|
# it might be required to disable advertisements.
|
||||||
|
advertise: true
|
||||||
|
|
||||||
|
# In case both external access and advertise are enabled
|
||||||
|
# then a service account would be required to be able to
|
||||||
|
# gather the public ip from a node.
|
||||||
|
serviceAccount: "nats-server"
|
||||||
|
```
|
||||||
|
|
||||||
|
Where the service account named `nats-server` has the following RBAC policy for example:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
---
|
||||||
|
apiVersion: v1
|
||||||
|
kind: ServiceAccount
|
||||||
|
metadata:
|
||||||
|
name: nats-server
|
||||||
|
namespace: default
|
||||||
|
---
|
||||||
|
apiVersion: rbac.authorization.k8s.io/v1
|
||||||
|
kind: ClusterRole
|
||||||
|
metadata:
|
||||||
|
name: nats-server
|
||||||
|
rules:
|
||||||
|
- apiGroups: [""]
|
||||||
|
resources:
|
||||||
|
- nodes
|
||||||
|
verbs: ["get"]
|
||||||
|
---
|
||||||
|
apiVersion: rbac.authorization.k8s.io/v1
|
||||||
|
kind: ClusterRoleBinding
|
||||||
|
metadata:
|
||||||
|
name: nats-server-binding
|
||||||
|
roleRef:
|
||||||
|
apiGroup: rbac.authorization.k8s.io
|
||||||
|
kind: ClusterRole
|
||||||
|
name: nats-server
|
||||||
|
subjects:
|
||||||
|
- kind: ServiceAccount
|
||||||
|
name: nats-server
|
||||||
|
namespace: default
|
||||||
|
```
|
||||||
|
|
||||||
|
The container image of the initializer can be customized via:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
bootconfig:
|
||||||
|
image: connecteverything/nats-boot-config:0.5.2
|
||||||
|
pullPolicy: IfNotPresent
|
||||||
|
```
|
||||||
|
|
||||||
|
### Using LoadBalancers
|
||||||
|
|
||||||
|
In case of using a load balancer for external access, it is recommended to disable no advertise
|
||||||
|
so that internal ips from the NATS Servers are not advertised to the clients connecting through
|
||||||
|
the load balancer.
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
image: nats:alpine
|
||||||
|
|
||||||
|
cluster:
|
||||||
|
enabled: true
|
||||||
|
noAdvertise: true
|
||||||
|
|
||||||
|
leafnodes:
|
||||||
|
enabled: true
|
||||||
|
noAdvertise: true
|
||||||
|
|
||||||
|
natsbox:
|
||||||
|
enabled: true
|
||||||
|
```
|
||||||
|
|
||||||
|
Then could use an L4 enabled load balancer to connect to NATS, for example:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: v1
|
||||||
|
kind: Service
|
||||||
|
metadata:
|
||||||
|
name: nats-lb
|
||||||
|
spec:
|
||||||
|
type: LoadBalancer
|
||||||
|
selector:
|
||||||
|
app: nats
|
||||||
|
ports:
|
||||||
|
- protocol: TCP
|
||||||
|
port: 4222
|
||||||
|
targetPort: 4222
|
||||||
|
name: nats
|
||||||
|
- protocol: TCP
|
||||||
|
port: 7422
|
||||||
|
targetPort: 7422
|
||||||
|
name: leafnodes
|
||||||
|
- protocol: TCP
|
||||||
|
port: 7522
|
||||||
|
targetPort: 7522
|
||||||
|
name: gateways
|
||||||
|
```
|
||||||
|
|
||||||
|
## Gateways
|
||||||
|
|
||||||
|
A super cluster can be formed by pointing to remote gateways.
|
||||||
|
You can find more about gateways in the NATS documentation:
|
||||||
|
https://docs.nats.io/nats-server/configuration/gateways
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
gateway:
|
||||||
|
enabled: false
|
||||||
|
name: 'default'
|
||||||
|

|
||||||
|
|
||||||
|
For example, given the following `PersistentVolumeClaim`:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
---
|
||||||
|
kind: PersistentVolumeClaim
|

|
|
||||||
|
You can start JetStream so that one pod is bounded to it:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
image: synadia/nats-server:nightly
|
||||||
|
|
||||||
|
jetstream:
|
||||||
|
enabled: true
|
||||||
|
|
||||||
|
fileStorage:
|
||||||
|
enabled: true
|
||||||
|
storageDirectory: /data/
|
||||||
|
existingClaim: nats-js-disk
|
||||||
|
claimStorageSize: 3Gi
|
||||||
|
```
|
||||||
|
|
||||||
|
### Clustering example
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
|
||||||
|
nats:
|
||||||
|
image: synadia/nats-server:nightly
|
||||||
|
|
||||||
|
jetstream:
|
||||||
|
enabled: true
|
||||||
|
|
||||||
|
memStorage:
|
||||||
|
enabled: true
|
||||||
|
size: "2Gi"
|
||||||
|
|
||||||
|
fileStorage:
|
||||||
|
enabled: true
|
||||||
|
size: "1Gi"
|
||||||
|
storageDirectory: /data/
|
||||||
|
storageClassName: default
|
||||||
|
|
||||||
|
cluster:
|
||||||
|
enabled: true
|
||||||
|
# Cluster name is required, by default will be release name.
|
||||||
|
# name: "nats"
|
||||||
|
replicas: 3
|
||||||
|
```
|
||||||
|
|
||||||
|
## Misc
|
||||||
|
|
||||||
|
### NATS Box
|
||||||
|
|
||||||
|
A lightweight container with NATS and NATS Streaming utilities that is deployed along the cluster to confirm the setup.
|
||||||
|
You can find the image at: https://github.com/nats-io/nats-box
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
natsbox:
|
||||||
|
enabled: true
|
||||||
|
image: synadia/nats-box:latest
|
||||||
|
pullPolicy: IfNotPresent
|
||||||
|
|
||||||
|
# credentials:
|
||||||
|
# secret:
|
||||||
|
# name: nats-sys-creds
|
||||||
|
# key: sys.creds
|
||||||
|
```
|
||||||
|
|
||||||
|
### Configuration Reload sidecar
|
||||||
|
|
||||||
|
The NATS config reloader image to use:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
reloader:
|
||||||
|
enabled: true
|
||||||
|
image: connecteverything/nats-server-config-reloader:0.6.0
|
||||||
|
pullPolicy: IfNotPresent
|
||||||
|
```
|
||||||
|
|
||||||
|
### Prometheus Exporter sidecar
|
||||||
|
|
||||||
|
You can toggle whether to start the sidecar that can be used to feed metrics to Prometheus:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
exporter:
|
||||||
|
enabled: true
|
||||||
|
image: synadia/prometheus-nats-exporter:0.5.0
|
||||||
|
pullPolicy: IfNotPresent
|
||||||
|
```
|
||||||
|
|
||||||
|
### Prometheus operator ServiceMonitor support
|
||||||
|
|
||||||
|
You can enable prometheus operator ServiceMonitor:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
exporter:
|
||||||
|
# You have to enable exporter first
|
||||||
|
enabled: true
|
||||||
|
serviceMonitor:
|
||||||
|
enabled: true
|
||||||
|
## Specify the namespace where Prometheus Operator is running
|
||||||
|
# namespace: monitoring
|
||||||
|
# ...
|
||||||
|
```
|
||||||
|
|
||||||
|
### Pod Customizations
|
||||||
|
|
||||||
|
#### Security Context
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
# Toggle whether to use setup a Pod Security Context
|
||||||
|
# ## ref: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/
|
||||||
|
securityContext:
|
||||||
|
fsGroup: 1000
|
||||||
|
runAsUser: 1000
|
||||||
|
runAsNonRoot: true
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Affinity
|
||||||
|
|
||||||
|
<https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity>
|
||||||
|
|
||||||
|
`matchExpressions` must be configured according to your setup
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
affinity:
|
||||||
|
nodeAffinity:
|
||||||
|
requiredDuringSchedulingIgnoredDuringExecution:
|
||||||
|
nodeSelectorTerms:
|
||||||
|
- matchExpressions:
|
||||||
|
- key: node.kubernetes.io/purpose
|
||||||
|
operator: In
|
||||||
|
values:
|
||||||
|
- nats
|
||||||
|
podAntiAffinity:
|
||||||
|
requiredDuringSchedulingIgnoredDuringExecution:
|
||||||
|
- labelSelector:
|
||||||
|
matchExpressions:
|
||||||
|
- key: app
|
||||||
|
operator: In
|
||||||
|
values:
|
||||||
|
- nats
|
||||||
|
- stan
|
||||||
|
topologyKey: "kubernetes.io/hostname"
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Service topology
|
||||||
|
|
||||||
|
[Service topology](https://kubernetes.io/docs/concepts/services-networking/service-topology/) is disabled by default, but can be enabled by setting `topologyKeys`. For example:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
topologyKeys:
|
||||||
|
- "kubernetes.io/hostname"
|
||||||
|
- "topology.kubernetes.io/zone"
|
||||||
|
- "topology.kubernetes.io/region"
|
||||||
|
```
|
||||||
|
|
||||||
|
#### CPU/Memory Resource Requests/Limits
|
||||||
|
Sets the pods cpu/memory requests/limits
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nats:
|
||||||
|
resources:
|
||||||
|
requests:
|
||||||
|
cpu: 2
|
||||||
|
memory: 4Gi
|
||||||
|
limits:
|
||||||
|
cpu: 4
|
||||||
|
memory: 6Gi
|
||||||
|
```
|
||||||
|
|
||||||
|
No resources are set by default.
|
||||||
|
|
||||||
|
#### Annotations
|
||||||
|
|
||||||
|
<https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations>
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
podAnnotations:
|
||||||
|
key1 : "value1",
|
||||||
|
key2 : "value2"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Name Overides
|
||||||
|
|
||||||
|
Can change the name of the resources as needed with:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
nameOverride: "my-nats"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Image Pull Secrets
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
imagePullSecrets:
|
||||||
|
- name: myRegistry
|
||||||
|
```
|
||||||
|
|
||||||
|
Adds this to the StatefulSet:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
spec:
|
||||||
|
imagePullSecrets:
|
||||||
|
- name: myRegistry
|
||||||
|
```

You can find more information about running NATS on Kubernetes
|
||||||
|
in the NATS documentation website:
|
||||||
|

|
https://docs.nats.io/nats-on-kubernetes/nats-kubernetes
|
||||||
|
|
||||||
|
{{- if .Values.natsbox.enabled }}
|
||||||
|
|
||||||
|
NATS Box has been deployed into your cluster, you can
|
||||||
|
now use the NATS tools within the container as follows:
|
||||||
|
|
||||||
|
kubectl exec -n {{ .Release.Namespace }} -it deployment/{{ template "nats.fullname" . }}-box -- /bin/sh -l
|
||||||
|
|
||||||
|
nats-box:~# nats-sub test &
|
||||||
|
nats-box:~# nats-pub test hi
|
||||||
|
nats-box:~# nc {{ template "nats.fullname" . }} 4222
|
||||||
|
|
||||||
|
{{- end }}
|
||||||
|
|
||||||
|
Thanks for using NATS!
