-----------------------------------
Summary: camel-yaml-dsl - Deprecate Pipe (aka KameletBinding)
support
Key: CAMEL-24807
URL: https://issues.apache.org/jira/browse/CAMEL-24807
Project: Camel
Issue Type: Improvement
Components: camel-yaml-dsl
Reporter: Claus Ibsen
The YAML DSL can load Kubernetes-style {{kind: Pipe}} (formerly
{{KameletBinding}}) files from Camel K, converting
{{source}}/{{sink}}/{{steps}} and the Pipe {{errorHandler}} into a regular
route at load time ({{YamlRoutesBuilderLoader.preConfigurePipe}}, the
{{*.pipe.yaml}} extension).
This is a Camel K construct rather than a Camel feature. A plain YAML route is
more expressive (any EIP, multiple routes per file, error handling, route
configuration), is what the tooling, the catalog, the validator and the AI
tools work on, and is what the documentation teaches. Keeping a second, more
limited way of writing the same thing costs maintenance for little gain.
Deprecate Pipe support in the YAML DSL in 4.x so it can be removed in the next
major:
* log a deprecation WARN when a Pipe file is loaded, pointing to writing a
plain route instead
* mark the Pipe handling in {{YamlRoutesBuilderLoader}} and the {{pipe.yaml}}
extension as deprecated
* document the deprecation in the YAML DSL page and in the upgrade guide, with
an example of the equivalent route
* camel-jbang: the {{init}} Pipe template ({{init-pipe.yaml.ftl}},
{{pipe.yaml.tmpl}}) and the {{bind}} command follow CAMEL-21521
Related: CAMEL-21521 (remove the {{camel bind}} command).
