Requirements

StackState Self-hosted v4.5.x
This page describes StackState v4.5.x. The StackState 4.5 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.5 version range to upgrade to a more recent release.
Go to the documentation for the latest StackState release.

Kubernetes and OpenShift

Supported versions

StackState can be installed on a Kubernetes or OpenShift cluster using the Helm charts provided by StackState. These Helm charts require Helm v3.x to install and are supported on:
  • Amazon Elastic Kubernetes Service (EKS): 1.18 to 1.21
  • Azure Kubernetes Service (AKS): 1.18 to 1.21
  • OpenShift: 4.7 to 4.8

Node sizing

For a standard deployment, the StackState Helm chart will deploy backend services in a redundant setup with 3 instances of each service. The nodes required for different environments:
Recommended setup
Minimal setup
Non-high availability setup
Requirements for the recommended high availability setup:
  • Amazon EKS: 6 instances of type m5.2xlarge or m4.2xlarge
  • Azure AKS: 6 instances of type D8s v3 or D8as V4 (Intel or AMD CPUs)
  • Virtual machines: 6 nodes with 32GB memory, 8 vCPUs
Requirements for the minimal high availability setup:
  • Amazon EKS: 5 instances of type m5.2xlarge or m4.2xlarge
  • Azure AKS: 5 instances of type D8s v3 or D8as V4 (Intel or AMD CPUs)
  • Virtual machines: 5 nodes with 32GB memory, 8 vCPUs
Optionally, a non-high availability setup can be configured which has the following requirements:
  • Amazon EKS: 3 instances of type m5.2xlarge or m4.2xlarge
  • Azure AKS: 3 instances of type D8s v3 or D8as V4 (Intel or AMD CPUs)
  • Virtual machines: 3 nodes with 32GB memory, 8 vCPUs

Docker images

For a list of all Docker images used, see the image overview.

Storage

StackState uses persistent volume claims for the services that need to store data. The default storage class for the cluster will be used for all services unless this is overridden by values specified on the command line or in a values.yaml file. All services come with a pre-configured volume size that should be good to get you started, but can be customized later using variables as required.
For more details on the defaults used, see the page Configure storage.

Ingress

By default, the StackState Helm chart will deploy a router pod and service. This service's port 8080 is the only entry point that needs to be exposed via Ingress. You can access StackState without configuring Ingress by forwarding this port:
kubectl port-forward service/<helm-release-name>-distributed-router 8080:8080
When configuring Ingress, make sure to allow for large request body sizes (50MB) that may be sent occasionally by data sources like the StackState Agent or the AWS integration.
For more details on configuring Ingress, have a look at the page Configure Ingress docs.

Namespace resource limits

It is not recommended to set a ResourceQuota as this can interfere with resource requests. The resources required by StackState will vary according to the features used, configured resource limits and dynamic usage patterns, such as Deployment or DaemonSet scaling.
If it is necessary to set a ResourceQuota for your implementation, the namespace resource limit should be set to match the node sizing requirements. For example, using the recommended node sizing for virtual machines (6 nodes with 32GB memory, 8 vCPUs), the namespace resource limit should be 6*32GB = 192GB and 6*8 vCPUs = 48 vCPUs.

Linux

Size requirements

Production setup

The StackState production setup runs on two machines and requires:
StackState node:
  • 32GB of RAM
  • 500GB disk space (available under /opt/stackstate)
  • 8 cores CPU
StackGraph node:
  • 24GB of RAM
  • 500GB disk space (available under /opt/stackstate)
  • 8 cores CPU

POC setup

The POC setup runs on a single node and requires:
  • 32GB of RAM
  • 500GB disk space (available under /opt/stackstate)
  • 8 cores CPU

Development setup

The development setup runs on a single node and requires:
  • 16GB of RAM
  • 500GB disk space (available under /opt/stackstate)
  • 4 cores CPU

AWS requirements

To meet StackState minimal requirements, the AWS instance type needs to have at least:
  • 4 CPU cores
  • 16GB of memory, e.g., m5.xlarge.
The AWS CLI has to be installed on the EC2 instance that is running StackState.

Networking

Listed ports are TCP ports.

Production deployment

A production deployment separates StackState and StackState's database processes; StackGraph.
StackState has to be reachable on port 7070 by any supported browser. StackState port 7077 must be reachable from any system that is pushing data to StackState
StackGraph should be reachable by StackState on ports 2181, 8020, 15165, 16000, 16020, 50010.
The following ports can be opened for monitoring, but are also useful when troubleshooting:
  • StackState: 9010, 9011, 9020, 9021, 9022, 9023, 9024, 9025, 9026
  • StackGraph: 9001, 9002, 9003, 9004, 9005, 9006, 16010, 16030, 50070, 50075

Development/POC deployment

StackState has to be reachable on port 7070 by any supported browser. StackState port 7077 must be reachable from any system that is pushing data to StackState
