Requirements
StackState Self-hosted v5.1.x
Overview
This page details the requirements for all supported installations of StackState:
Requirements for networking and the StackState client (browser) can be found at the bottom of the page.
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): 1.21 to 1.28
Azure Kubernetes Service (AKS): 1.20 to 1.28
OpenShift: 4.8 to 4.10
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 number of nodes required for environments with out-of-the-box settings are listed below, note that these may change based on system tuning:
The recommended requirements include spare CPU/Memory capacity to ensure smooth application rolling update.
Requirements for the recommended high availability setup with backups enabled:
Node requirements: minimum 8 vCPUs, minimum 32GB memory
Total of 56 vCPUs available for StackState
Total of 120 GB memory available for StackState
Total of 2 TB disk space for data storing services (doesn't include disk space required for backups)
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:
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 isn't 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's 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.

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. For example, m5.xlarge.
The AWS CLI has to be installed on the EC2 instance that's running StackState.
Networking
All 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 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 pushing data to StackState
The following ports can be opened for monitoring, but are also useful when troubleshooting: 9001, 9002, 9003, 9004, 9005, 9006, 9010, 9011, 9020, 9021, 9022, 9023, 9024, 9025, 9026, 16010, 16030, 50070, 50075
