System requirements
On-Premise hosts architecture
Example of On-Premise hosts architecture:
Common requirements
-
Operating system on hosts:
- Ubuntu 20.04 LTS, 22.04 LTS
- Oracle Linux 8
- Astra Linux "Oryol"
- ALT Linux 10
-
General-purpose software:
- Kubernetes: from 1.21 to 1.29
- Docker Engine: 20.10.* or later
- Docker Registry: 2.* or later
-
Data storage software required for some On-Premise services (see the list of data storage for services):
- S3 compatible storage: e.g., Ceph: 14.2.22
- PostgreSQL: 14.*
- PostgreSQL extensions: PostGIS 3.3, JsQuery 1.*, PL/pgSQL 1.*, pg_trgm 1.4
- Apache Kafka: 3.0.*
- Apache Cassandra: 4.*
- Elasticsearch: 7.*
- Redis: 6.* (stable release)
- Apache Zookeeper: 3.6.3
Computational resources
The performance requirements for the On-Premise system are specified in the Helm charts. To check resources amount for each service, go to a corresponding folder in the GitHub repository, open the values.yaml
file, and find the resources
settings.
To ensure that Pods are placed on the nodes of the Kubernetes cluster, it is recommended to specify resources
for all the components. Learn more about Resource Management for Pods and Containers in Kubernetes.
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).
