# 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"
|
||||
# credentials:
|
||||
# secret:
|
||||
# name: leafnode-creds
|
||||
# key: TA.creds
|
||||
# tls:
|
||||
# secret:
|
||||
# name: nats-leafnode-tls
|
||||
# ca: "ca.crt"
|
||||
# cert: "tls.crt"
|
||||
# key: "tls.key"

## 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: natsio/nats-boot-config:latest
|
||||
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.kubernetes.io/name: 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'
|

```
|

|
||||
## Auth setup
|
||||
|
||||
### Auth with a Memory Resolver
|
||||
|
||||
```yaml
|
||||
auth:
|
||||
enabled: true
|
||||
|
||||
# Reference to the Operator JWT.
|
||||
operatorjwt:
|
||||
configMap:
|
||||
name: operator-jwt
|
||||
key: KO.jwt
|
||||
|
||||
# Public key of the System Account
|
||||
systemAccount:
|
||||
|
||||
resolver:
|
||||
############################
|
||||
# #
|
||||
# Memory resolver settings #
|
||||
# #
|
||||
##############################
|
||||
type: memory
|
||||
|
||||
#
|
||||
# Use a configmap reference which will be mounted
|
||||
# into the container.
|
||||
#
|
||||
configMap:
|
||||
name: nats-accounts
|
||||
key: resolver.conf
|
||||
```
|
||||
|
||||
### Auth using an Account Server Resolver
|
||||
|
||||
```yaml
|
||||
auth:
|
||||
enabled: true
|
||||
|
||||
# Reference to the Operator JWT.
|
||||
operatorjwt:
|
||||
configMap:
|
||||
name: operator-jwt
|
||||
key: KO.jwt
|
||||
|
||||
# Public key of the System Account
|
||||
systemAccount:
|
||||
|
||||
resolver:
|
||||
##########################
|
||||
# #

|
||||
type: URL
|
||||
url: "http://nats-account-server:9090/jwt/v1/accounts/"
|
||||
```
|
||||
|
||||
## JetStream
|
||||
|
||||
### Setting up Memory and File Storage
|
||||
|
||||
```yaml
|
||||
nats:
|
||||
image: nats:alpine
|
||||
|
||||
jetstream:
|
||||
enabled: true
|
||||
|
||||
memStorage:
|
||||
enabled: true
|
||||
size: 2Gi
|
||||
|
||||
fileStorage:
|
||||
enabled: true
|
||||
size: 1Gi
|
||||
storageDirectory: /data/
|
||||
storageClassName: default
|
||||
```
|
||||
|
||||
### Using with an existing PersistentVolumeClaim
|
||||
|
||||
For example, given the following `PersistentVolumeClaim`:
|
||||
|
||||
```yaml
|
||||
---
|
||||
kind: PersistentVolumeClaim
|
||||
apiVersion: v1
|
||||
metadata:
|
||||
name: nats-js-disk
|
||||
annotations:
|
||||
volume.beta.kubernetes.io/storage-class: "default"
|
||||
spec:
|
||||
accessModes:
|
||||
- ReadWriteOnce
|
||||
resources:
|
||||
requests:
|
||||
storage: 3Gi
|
||||
```
|
||||
|
||||
You can start JetStream so that one pod is bounded to it:
|
||||
|
||||
```yaml
|
||||
nats:
|
||||
image: nats:alpine
|
||||
|
||||
jetstream:
|
||||
enabled: true
|
||||
|
||||
fileStorage:
|
||||
enabled: true
|
||||
storageDirectory: /data/
|
||||
existingClaim: nats-js-disk
|
||||
claimStorageSize: 3Gi
|
||||
```
|
||||
|
||||
### Clustering example
|
||||
|
||||
```yaml
|
||||
|
||||
nats:
|
||||
image: nats:alpine
|
||||
|
||||
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
|
||||
```
|
||||
|
||||
### Basic Authentication and JetStream
|
||||
|
||||
```yaml
|
||||
nats:
|
||||

|
||||
|
||||
jetstream:
|
||||

|
||||
|
||||
memStorage:
|
||||
enabled: true
|
||||
size: "2Gi"
|
||||
|
||||
fileStorage:
|
||||
enabled: true
|
||||
size: "8Gi"
|
||||
storageDirectory: /data/
|
||||
storageClassName: gp2
|
||||
|
||||
cluster:
|
||||
enabled: true
|
||||
# Can set a custom cluster name
|
||||
# name: "nats"
|
||||
replicas: 3
|
||||
|
||||
auth:
|
||||
enabled: true
|
||||
|
||||
systemAccount: sys
|
||||
|
||||
basic:
|
||||
accounts:
|
||||
sys:
|
||||
users:
|
||||
- user: sys
|
||||
pass: sys
|
||||
js:
|
||||
jetstream: true
|
||||
users:
|
||||
- user: foo
|
||||
```
|
||||
|
||||
### NATS Resolver setup example
|
||||
|
||||
As of NATS v2.2, the server now has a built-in NATS resolver of accounts.
|
||||
The following is an example guide of how to get it configured.
|
||||
|
||||
```sh
|
||||
# Create a working directory to keep the creds.
|
||||
mkdir nats-creds
|
||||
cd nats-creds
|
||||
|
||||
# This just creates some accounts for you to get started.
|
||||
curl -fSl https://nats-io.github.io/k8s/setup/nsc-setup.sh | sh
|
||||
source .nsc.env
|
||||
|
||||
# You should have some accounts now, at least the following.
|
||||
nsc list accounts
|
||||
+-------------------------------------------------------------------+
|
||||
| Accounts |
|
||||
+--------+----------------------------------------------------------+
|
||||
| Name | Public Key |
|
||||
+--------+----------------------------------------------------------+
|
||||
| A | ABJ4OIKBBFCNXZDP25C7EWXCXOVCYYAGBEHFAG7F5XYCOYPHZLNSJYDF |
|
||||
| B | ACVRK7GFBRQUCB3NEABGQ7XPNED2BSPT27GOX5QBDYW2NOFMQKK755DJ |
|
||||
| SYS | ADGFH4NYV5V75SVM5DYSW5AWOD7H2NRUWAMO6XLZKIDGUWYEXCZG5D6N |
|
||||
+--------+----------------------------------------------------------+
|
||||
|
||||
# Now create an account with JetStream support
|
||||
export account=JS1
|
||||
nsc add account --name $account
|
||||
nsc edit account --name $account --js-disk-storage -1 --js-consumer -1 --js-streams -1
|
||||
nsc add user -a $account js-user
|
||||
```
|
||||
|
||||
Next, generate the NATS resolver config. This will be used to fill in the values of the YAML in the Helm template.
|
||||
For example the result of generating this:
|
||||
|
||||
```sh
|
||||
nsc generate config --sys-account SYS --nats-resolver
|
||||
|
||||
# Operator named KO

Now we start the server with the NATS Account Resolver (`auth.resolver.type=full`):
|

|

```yaml

|
||||
```
|
||||
|
||||
Finally, using a local port-forward make it possible to establish a connection to one of the servers and upload the accounts.
|
||||
|
||||
```sh
|
||||
nsc push --system-account SYS -u nats://localhost:4222 -A
|
||||
[ OK ] push to nats-server "nats://localhost:4222" using system account "SYS":
|
||||
[ OK ] push JS1 to nats-server with nats account resolver:
|
||||
[ OK ] pushed "JS1" to nats-server nats-0: jwt updated
|
||||
[ OK ] pushed "JS1" to nats-server nats-1: jwt updated
|
||||
[ OK ] pushed "JS1" to nats-server nats-2: jwt updated
|
||||
[ OK ] pushed to a total of 3 nats-server
|
||||
```
|
||||
|
||||
Now you should be able to use JetStream and the NATS based account resolver:
|
||||
|
||||
```sh
|
||||
nats stream ls -s localhost --creds ./nsc/nkeys/creds/KO/JS1/js-user.creds
|
||||
No Streams defined
|
||||
```
|
||||
|
||||
## 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: nats:alpine
|
||||
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: natsio/nats-server-config-reloader:latest
|
||||
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: natsio/prometheus-nats-exporter:latest
|
||||
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
|
||||
```
