This updates the StatefulSet `spec.volumeClaimTemplates` field, which is immutable and cannot be changed on an existing StatefulSet; to upgrade from an older chart version, add the value: - ```yaml - nats: - jetstream: - fileStorage: - # add if enabled was previously the default setting - # not recommended; it would be better to migrate to a StatefulSet with storage enabled - enabled: false - # add if size was previously the default setting - size: 1Gi - ``` -- **0.12.0**: The `podManagementPolicy` value was introduced and set to `Parallel` by default, which controls the StatefulSet `spec.podManagementPolicy` field. This field is immutable and cannot be changed on an existing StatefulSet; to upgrade from an older chart version, add the value: - ```yaml - podManagementPolicy: OrderedReady - ``` - -## Configuration - -### Server Image - -```yaml -# use a specific versions -nats: - image: - tag: X.Y.Z-alpine - -# fully custom location -nats: - image: - registry: my.custom.registry - repository: my-nats - tag: latest - pullPolicy: Always -``` - -### 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 -``` - -#### Setting Go Memory Limit (Recommended) - -Since NATS Server v2.9 release, it is possible to use the `GOMEMLIMIT` environment variable to signal memory limits to the Go runtime (which is by default unaware of cgroups memory limits). You should set this to about 90% of the intended available memory resources for the NATS Server container. - -```yaml -nats: - gomemlimit: "4GiB" -``` - -### 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.

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 - # 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: - tag: X.Y.Z -``` - -### Using LoadBalancers - -In case of using a load balancer for external access, it is recommended to disable advertise -so that internal ips from the NATS Servers are not advertised to the clients connecting through -the load balancer. - -```yaml -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 -``` - -### Using NATS Chart as a Dependency - -In order to fully manage your deployment through Helm, you can use `nats` as a [helm dependency](https://helm.sh/docs/helm/helm_dependency/#helm-dependency). This is our recommend approach for exposing your NATS deployment with Services or WebSocket Ingresses. - -1. Example uses a helm chart named `mynats` (example: `helm create mynats`) -2. In `Chart.yaml` add the following dependencies block - ```yaml - dependencies: - - name: nats - version: 0.18.0 - repository: https://nats-io.github.io/k8s/helm/charts/ - ``` -3. Run `helm dep update` now (and any time you update the `nats` dependency version) -4. Add `nats` settings to the `values.yaml` file: - ```yaml - # notice the extra nats key here, must match the dependency name in Chart.yaml - nats: - nats: - jetstream: - enabled: true - cluster: - enabled: true - # disable cluster advertisements when running behind a load balancer - noAdvertise: true - - # add whatever other nats settings you need here - ``` -5. Add a template for your service to `templates/service-lb.yaml`: - ```yaml - apiVersion: v1 - kind: Service - metadata: - name: {{ include "mynats.fullname" . }}-lb - labels: - {{- include "mynats.labels" . | nindent 4 }} - spec: - type: LoadBalancer - selector: - {{- include "nats.selectorLabels" .Subcharts.nats | nindent 4 }} - ports: - - name: nats - port: 4222 - protocol: TCP - targetPort: 4222 - ``` - -## 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 - -> ⚠️ Note: When using Gateways and JetStream make sure that the deployment name is different so that the generated server names do not
