Docker 4.22 Introduces Resource Saver And Improvements To Docker Compose
InfoQ, Monday, October 2,2023
Docker Desktop 4.22 has been released, featuring the new "Resource Saver" functionality designed to reduce idle memory and CPU usage, ensuring optimal utilization of machine resources. Additionally, Docker Compose now supports the inclusion of subprojects, simplifying the process of modularizing complex applications into separate Compose files.
Enhancements have also been made to role-based access control (RBAC) with the introduction of an Editor role, allowing administrators to delegate repository management tasks.
In version 4.22, Docker Desktop introduces the Resource Saver feature for Mac and Windows. When Docker Desktop remains idle without any active containers for 30 seconds, the memory and CPU footprint is automatically reduced, optimizing resource allocation and freeing up system resources for other tasks. A leaf icon appears on the Docker Desktop menu and dashboard sidebar to indicate that Resource Saver mode is activated.
