odo build-images

odo can build container images based on Dockerfiles, and push these images to their registries.

When running the command odo build-images, odo searches for all components in the devfile.yaml with the image type, for example:

components:
- image:
    imageName: quay.io/myusername/myimage
    dockerfile:
      uri: ./Dockerfile
      buildContext: ${PROJECTS_ROOT}
  name: component-built-from-dockerfile

The uri field indicates the relative path of the Dockerfile to use, relative to the directory containing the devfile.yaml. As indicated in the Devfile specification, uri could also be an HTTP or HTTPS URL.

The buildContext indicates the directory used as build context. The default value is ${PROJECT_SOURCE}.

For each image component, odo executes either podman or docker (the first one found, in this order), to build the image with the specified Dockerfile, build context and arguments.

If the --push flag is passed to the command, the images will be pushed to their registries after they are built.

Faking the image build​

You can also fake the image build by exporting PODMAN_CMD=echo or DOCKER_CMD=echo to your environment. Read environment variables controlling odo behaviour for more information.
