Limiting resources usage

This section describes how to limit resource use in devfiles.

Procedure

  1. Specify container memory limit and memory request for components

    To specify a container memory limit for container, use the memoryLimit parameter. To specify a container memory request, use the memoryRequest parameter:

    Example 1. Specify container memory limit and memory request for components
      components:
   - name: maven
     container:
      image: eclipse/maven-jdk8:latest
      memoryLimit: 512M
      memoryRequest: 256M

    This limit applies to every container of the given component.

    When not specified, the values may or may not be inferred from the application that consumes the devfile or from the underlying platform (for example, Kubernetes).

  2. Specify container CPU limit and container CPU request for components

    To specify a container CPU limit for container, use the cpuLimit parameter. To specify a container CPU request for container, use the cpuRequest parameter:

    Example 2. Specify container CPU limit and CPU request for components
      components:
   - name: maven
     container:
      image: eclipse/maven-jdk8:latest
      cpuLimit: 750m
      cpuRequest: 450m

    This limit applies to every container of the given component.

    When not specified, the values may or may not be inferred from the application that consumes the devfile or from the underlying platform (for example, Kubernetes).
