第 9 章 Performing advanced builds
The following sections provide instructions for advanced build operations including setting build resources and maximum duration, assigning builds to nodes, chaining builds, build pruning, and build run policies.
9.1. Setting build resources
By default, builds are completed by pods using unbound resources, such as memory and CPU. These resources can be limited.
Procedure
You can limit resource use in two ways:
- Limit resource use by specifying resource limits in the default container limits of a project.
Limit resource use by specifying resource limits as part of the build configuration. ** In the following example, each of the
resources,cpu, andmemoryparameters are optional:apiVersion: "v1" kind: "BuildConfig" metadata: name: "sample-build" spec: resources: limits: cpu: "100m" 1 memory: "256Mi" 2However, if a quota has been defined for your project, one of the following two items is required:
A
resourcessection set with an explicitrequests:resources: requests: 1 cpu: "100m" memory: "256Mi"- 1
- The
requestsobject contains the list of resources that correspond to the list of resources in the quota.
A limit range defined in your project, where the defaults from the
LimitRangeobject apply to pods created during the build process.Otherwise, build pod creation will fail, citing a failure to satisfy quota.
