Spec

Property Required Updatable Default Type Description
cpu 1 string

CPU(s) (cores) used for every instance of a SGCluster. Please note that every StackGres pod contains not only the Patroni+Postgres container, but several other sidecar containers. While the majority of the resources are devoted to the main Postgres container, some CPU is needed for the sidecars.

The number of cores set is split between all the containers.

A minimum of 2 cores is recommended.

memory 2Gi string

RAM allocated to every instance of a SGCluster. The suffix Mi or Gi specifies Mebibytes or Gibibytes, respectively. Please note that every StackGres pod contains not only the Patroni+Postgres container, but several other sidecar containers. While the majority of the resources are devoted to the main Postgres container, some RAM is needed for the sidecars.

The amount of RAM set is split between all the containers.

A minimum of 2-4Gi is recommended.
