1.6. 输出定义

在 Build CR 中，您可以指定一个输出位置来推送镜像。当使用外部私有 registry 作为输出位置时，您必须指定一个 secret 才能访问该镜像。您还可以指定输出镜像的注解和标签。

注意

当您指定注解或标签时，输出镜像会被推送两次。第一个推送来自构建策略，第二次推送会更改镜像配置以添加注解和标签。

以下示例定义了推送镜像的公共 registry：

apiVersion: shipwright.io/v1beta1
kind: Build
metadata:
  name: s2i-nodejs-build
spec:
  source:
    git:
      url: https://github.com/shipwright-io/sample-nodejs
    contextDir: source-build/
  strategy:
    name: source-to-image
    kind: ClusterBuildStrategy
  paramValues:
  - name: builder-image
    value: docker.io/centos/nodejs-10-centos7
  output:
    image: image-registry.openshift-image-registry.svc:5000/build-examples/nodejs-ex

apiVersion: shipwright.io/v1beta1
kind: Build
metadata:
  name: s2i-nodejs-build
spec:
  source:
    git:
      url: https://github.com/shipwright-io/sample-nodejs
    contextDir: source-build/
  strategy:
    name: source-to-image
    kind: ClusterBuildStrategy
  paramValues:
  - name: builder-image
    value: docker.io/centos/nodejs-10-centos7
  output:
    image: image-registry.openshift-image-registry.svc:5000/build-examples/nodejs-ex
