31.3. 设置全局构建覆盖
您可以通过两种方式设置全局构建覆盖：
31.3.1. 使用 Ansible 配置全局构建覆盖
在集群安装过程中，BuildOverrides 插件可以使用以下参数来配置，该插件可在清单文件中配置：
-
openshift_buildoverrides_force_pull -
openshift_buildoverrides_image_labels -
openshift_buildoverrides_nodeselectors -
openshift_buildoverrides_annotations -
openshift_buildoverrides_tolerations
例 31.2. 使用 Ansible 构建覆盖配置示例
# These options configure the BuildOverrides admission controller which injects
# configuration into Builds.
openshift_buildoverrides_force_pull=true
openshift_buildoverrides_image_labels=[{'name':'imagelabelname1','value':'imagelabelvalue1'}]
openshift_buildoverrides_nodeselectors={'nodelabel1':'nodelabelvalue1'}
openshift_buildoverrides_annotations={'annotationkey1':'annotationvalue1'}
openshift_buildoverrides_tolerations=[{'key':'mykey1','value':'myvalue1','effect':'NoSchedule','operator':'Equal'}]
# Or you may optionally define your own build overrides configuration serialized as json
#openshift_buildoverrides_json='{"BuildOverrides":{"configuration":{"apiVersion":"v1","kind":"BuildOverridesConfig","forcePull":"true","tolerations":[{'key':'mykey1','value':'myvalue1','effect':'NoSchedule','operator':'Equal'}]}}}'注意
您必须使用 BuildOverrides 节点选择器来使用 BuildOverrides 插件覆盖容限。
