Adding an image component to a devfile

You can add an image component to a devfile.

Prerequisites

Procedure

Define a component using the type image.

Specify the location of the Dockerfile using the uri property. Specify arguments to be passed during the build with args. buildContext is the path of source directory to establish build context. If rootRequired is set to true, a privileged builder pod is required. The built container will be stored in the image provided by imageName.
An image dockerfile component
```
components:
  - name: outerloop-build
    image:
      imageName: python-image:latest
      autoBuild: true
      dockerfile:
        uri: docker/Dockerfile
        args:
            - "MY_ENV=/home/path"
        buildContext: .
        rootRequired: false
```
Alternatively, specify git and devfileRegistry as the image source.

When specifying git, fileLocation refers to the location of the Dockerfile in the git repository. Specify the remotes for the git repository and a checkoutFrom to indicate which revision to check the source from.

components:
  - name: outerloop-build
    image:
      imageName: python-image:latest
      dockerfile:
        git:
          fileLocation: "uri/Dockerfile"
          checkoutFrom:
            revision: "main"
            remote: "origin"
          remotes:
            "origin": "https://github.com/myorg/myrepo"
        buildContext: .
```
When specifying devfileRegistry, id refers to the Id in a devfile registry that contains a Dockerfile. registryUrl refers to the Devfile Registry URL to pull the Dockerfile from
