  • Operating system: Ubuntu 20.04 LTS
  • Kubernetes: 1.21
  • Docker Engine: 20.10.*
  • Docker Registry: 2.*

• Data storage software

  • Apache Cassandra: 3.*

System requirements

The performance requirements for the system on which the On-Premise complex should be run are specified in the Helm charts. To check requirements for each service of the complex, go to a corresponding folder in the GitHub repository, open the values.yaml file, and find the resources settings:

Code Example

resources:
    requests:
        cpu: 10m
        memory: 32Mi
    limits:
        cpu: 500m
        memory: 256Mi

Where:

• requests: the minimum amount of resources required to run the service.
• limits: the maximum amount of resources that can be allocated to run the service.
• cpu: the number of cores. If the value is specified as Xm, it is converted to millicores.
• memory: the amount of RAM in mebibytes (Mi).

Important Note:

The system requirements mentioned above are approximate, provided for informational purposes, and intended for test deployments.
