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 asX
m, 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.
