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 and for the container memory request, use the memoryRequest parameter:

   Specify container memory limit and memory request for components

   devfile.yaml

   components:  - name: maven  container:  image: eclipse/maven-jdk8:latest  memoryLimit: 512M  memoryRequest: 256M 

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

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

   Specify container CPU limit and CPU request for components

   devfile.yaml

   components:  - name: maven  container:  image: eclipse/maven-jdk8:latest  cpuLimit: 750m  cpuRequest: 450m 

3. 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).
