Configure Ingress

StackState Self-hosted v5.1.x

Overview

StackState can be exposed with Ingress resources. The example on this page shows how to configure an nginx-ingress controller using Helm for StackState running on Kubernetes.

Kubernetes: Configure ingress with Helm

The StackState Helm chart exposes an ingress section in its values. This is disabled by default. The example below shows how to use the Helm chart to configure an nginx-ingress controller with TLS encryption enabled. Note that setting up the controller itself and the certificates is beyond the scope of this document.
To configure the ingress for StackState, create a file ingress_values.yaml with contents like below. Replace MY_DOMAIN with your own domain (that is linked with your ingress controller) and set the correct name for the tls-secret. Consult the documentation of your ingress controller to ensure that the correct annotations are set. All fields below are optional, for example, if no TLS will be used, that section can be omitted.
ingress:
enabled: true
annotations:
nginx.ingress.kubernetes.io/proxy-body-size: "50m"
hosts:
- host: stackstate.MY_DOMAIN
tls:
- hosts:
- stackstate.MY_DOMAIN
secretName: tls-secret
The thing that stands out in this file is the nginx annotation to increase the allowed proxy-body-size to 50m (larger than any expected request). By default, nginx allows body sizes of maximum 1m. StackState Agents and other data providers can sometimes send much larger requests. For this reason, you should make sure that the allowed body size is large enough, regardless of whether you are using nginx or another ingress controller.
Include the ingress_values.yaml file when you run the helm upgrade command to deploy StackState:
helm upgrade \
--install \
--namespace "stackstate" \
--values "ingress_values.yaml" \
--values "values.yaml" \
stackstate \
stackstate/stackstate
