## MariaDB secondary container's resource requests and limits

944

## ref: https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/

945

## We usually recommend not to specify default resources and to leave this as a conscious

946

## choice for the user. This also increases chances charts run on environments with little

947

## resources, such as Minikube. If you do want to specify resources, uncomment the following

948

## lines, adjust them as necessary, and remove the curly braces after 'resources:'.

949

## @param secondary.resourcesPreset Set container resources according to one common preset (allowed values: none, nano, micro, small, medium, large, xlarge, 2xlarge). This is ignored if secondary.resources is set (secondary.resources is recommended for production).

950

951

952

## @param secondary.resources Set container requests and limits for different resources like CPU or memory (essential for production workloads)

## Mysqld Prometheus exporter resource requests and limits

1487

## ref: https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/

1488

## We usually recommend not to specify default resources and to leave this as a conscious

1489

## choice for the user. This also increases chances charts run on environments with little

1490

## resources, such as Minikube. If you do want to specify resources, uncomment the following

1491

## lines, adjust them as necessary, and remove the curly braces after 'resources:'.

1492

## @param metrics.resourcesPreset Set container resources according to one common preset (allowed values: none, nano, micro, small, medium, large, xlarge, 2xlarge). This is ignored if metrics.resources is set (metrics.resources is recommended for production).

1493

1494

resourcesPreset: "nano"

1495

## @param metrics.resources Set container requests and limits for different resources like CPU or memory (essential for production workloads)

1496

## Example:

1497

## resources:

1498

## requests:

1499

## cpu: 2

1500

## memory: 512Mi

1501
