Migrating components

This section describes how to migrate components to devfile v2. There ARE major changes in the components section of the devfile. A component specified in a v1.0 devfile will NOT work as it is in a devfile v2.0.

Procedure

  1. Component is a polymophic type

    For a better syntax validation component now is defined as a polymorphic type and can be implemented as container, kubernetes, openshift, plugin or volume.

    v2.0
---
components:
  - container:
        image: maven
        ...
  - container:
        image: nodejs
        ...
  - kubernetes:
       reference: https://.../mongo.yaml
