3장. Creating build inputs

Use different build inputs in OpenShift Container Platform to provide source content for your builds. Understanding the order of precedence helps ensure your builds use the correct sources.

The following build inputs are available and listed in order of precedence:

You can combine multiple inputs in a single build. However, as the inline Dockerfile takes precedence, it can overwrite any other file named Dockerfile provided by another input. Binary (local) input and Git repositories are mutually exclusive inputs.

You can use input secrets when you do not want certain resources or credentials used during a build to be available in the final application image produced by the build, or want to consume a value that is defined in a secret resource. External artifacts can be used to pull in additional files that are not available as one of the other build input types.

When you run a build:

The following example of a source definition includes multiple input types and an explanation of how they are combined. For more details on how each input type is defined, see the specific sections for each input type.

source:
  git:
    uri: https://github.com/openshift/ruby-hello-world.git
    ref: "master"
  images:
  - from:
      kind: ImageStreamTag
      name: myinputimage:latest
      namespace: mynamespace
    paths:
    - destinationDir: app/dir/injected/dir
      sourcePath: /usr/lib/somefile.jar
  contextDir: "app/dir"
  dockerfile: "FROM centos:7\nRUN yum install -y httpd"
