Chapter 4. Managing build output

Builds that use the docker or source-to-image (S2I) strategy result in the creation of a new container image. The image is then pushed to the container image registry specified in the

output

Build

If the output kind is

ImageStreamTag

DockerImage

spec:
  output:
    to:
      kind: "ImageStreamTag"
      name: "sample-image:latest"

spec:
  output:
    to:
      kind: "DockerImage"
      name: "my-registry.mycompany.com:5000/myimages/myimage:tag"

docker and source-to-image (S2I) strategy builds set the following environment variables on output images:

OPENSHIFT_BUILD_NAME

OPENSHIFT_BUILD_NAMESPACE

OPENSHIFT_BUILD_SOURCE

OPENSHIFT_BUILD_REFERENCE

OPENSHIFT_BUILD_COMMIT

Additionally, any user-defined environment variable, for example those configured with S2I] or docker strategy options, will also be part of the output image environment variable list.

docker and source-to-image (S2I)` builds set the following labels on output images:

io.openshift.build.commit.author

io.openshift.build.commit.date

io.openshift.build.commit.id

io.openshift.build.commit.message

io.openshift.build.commit.ref

io.openshift.build.source-location

You can also use the

BuildConfig.spec.output.imageLabels

spec:
  output:
    to:
      kind: "ImageStreamTag"
      name: "my-image:latest"
    imageLabels:
    - name: "vendor"
      value: "MyCompany"
    - name: "authoritative-source-url"
      value: "registry.mycompany.com"
