= odo build-images
|
|
|
|
`odo` can build container images based on Dockerfiles, and push these images to their registries.
|
|
|
|
When running the `odo build-images` command, `odo` searches for all components in the `devfile.yaml` with the `image` type, for example:
|
|
|
|
[source,yaml]
|
|
----
|
|
components:
|
|
- image:
|
|
imageName: quay.io/myusername/myimage
|
|
dockerfile:
|
|
uri: ./Dockerfile <1>
|
|
buildContext: ${PROJECTS_ROOT} <2>
|
|
name: component-built-from-dockerfile
|
|
----
|
|
<1> The `uri` field indicates the relative path of the Dockerfile to use, relative to the directory containing the `devfile.yaml`. The devfile specification indicates that `uri` could also be an HTTP URL, but this case is not supported by odo yet.
|
|
<2> The `buildContext` indicates the directory used as build context. The default value is `+${PROJECTS_ROOT}+`.
|
|
|
|
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 are pushed to their registries after they are built.
