Chapter 12. Build configuration resources Use the following procedure to configure build settings. 12.1. Build controller configuration parameters The build.config.openshift.io/cluster resource offers the following configuration parameters. Parameter Description Build Holds cluster-wide information on how to handle builds. The canonical, and only valid name is cluster . spec : Holds user-settable values for the build controller configuration. buildDefaults Controls the default information for builds. defaultProxy : Contains the default proxy settings for all build operations, including image pull or push and source download. You can override values by setting the HTTP_PROXY , HTTPS_PROXY , and NO_PROXY environment variables in the BuildConfig strategy. gitProxy : Contains the proxy settings for Git operations only. If set, this overrides any proxy settings for all Git commands, such as git clone . Values that are not set here are inherited from DefaultProxy. env : A set of default environment variables that are applied to the build if the specified variables do not exist on the build. imageLabels : A list of labels that are applied to the resulting image. You can override a default label by providing a label with the same name in the BuildConfig . resources : Defines resource requirements to execute the build. ImageLabel name : Defines the name of the label. It must have non-zero length. buildOverrides Controls override settings for builds. imageLabels : A list of labels that are applied to the resulting image. If you provided a label in the BuildConfig with the same name as one in this table, your label will be overwritten. nodeSelector : A selector which must be true for the build pod to fit on a node. tolerations : A list of tolerations that overrides any existing tolerations set on a build pod. BuildList items : Standard object's metadata. 12.2. Configuring build settings You can configure build settings by editing the build.config.openshift.io/cluster resource. Procedure Edit the build.config.openshift.io/cluster resource by entering the following command: USD oc edit build.config.openshift.io/cluster The following is an example build.config.openshift.io/cluster resource: apiVersion: config.openshift.io/v1 kind: Build 1 metadata: annotations: release.openshift.io/create-only: "true" creationTimestamp: "2019-05-17T13:44:26Z" generation: 2 name: cluster resourceVersion: "107233" selfLink: /apis/config.openshift.io/v1/builds/cluster uid: e2e9cc14-78a9-11e9-b92b-06d6c7da38dc spec: buildDefaults: 2 defaultProxy: 3 httpProxy: http://proxy.com httpsProxy: https://proxy.com noProxy: internal.com env: 4 - name: envkey value: envvalue gitProxy: 5 httpProxy: http://gitproxy.com httpsProxy: https://gitproxy.com noProxy: internalgit.com imageLabels: 6 - name: labelkey value: labelvalue resources: 7 limits: cpu: 100m memory: 50Mi requests: cpu: 10m memory: 10Mi buildOverrides: 8 imageLabels: 9 - name: labelkey value: labelvalue nodeSelector: 10 selectorkey: selectorvalue tolerations: 11 - effect: NoSchedule key: node-role.kubernetes.io/builds operator: Exists 1 Build : Holds cluster-wide information on how to handle builds.
