Overview

Smart ID now supports optional memory limits for all docker services. This allows administrators to control the maximum amount of memory each service is allowed to consume, helping to prevent any single service from using excessive system resources.

By default, no memory limits are applied, so existing deployments are not affected.

Each service has a corresponding configuration variable in the smartid.env file. These variables are commented out (disabled) by default. When uncommented and set to a value (for example, 3g for 3 gigabytes), the service will be restricted to that amount of memory. If a variable is not set, the service runs without any memory constraint, preserving the current behavior.

Configure memory limit

To apply a memory limit to a service, open smartid.env, find the relevant line, remove the # comment character, and set the desired value.

Example:

Before(no limit):
#POSTGRES_MEM_LIMIT=3g
After (limit applied):
POSTGRES_MEM_LIMIT=3g

Values use standard docker memory notation: 512m (megabytes), 1g (gigabytes), 2g, etc.
