In the recent PipelineResource working group and as presented during Oct. 2 working group, and related to tektoncd/pipeline#1369 :

In the most recent PipelineResource working group we landed on the idea of keeping PipelineResources as Alpha when the rest of the Tekton resources move to Beta. So with that approach we'll need to make sure that our docs correctly reflect the "right" way to work with external resources.

In this direction, we need to provide generic tasks that cover the use case of PipelineResource today, e.g. a GitTask, a DockerImageTask, etc... This issue is there to track work related to that.

Current PipelineResource to cover

• GitResource Add a git task to clone a repository without PipelineResource #123
• ClusterResource
• PullRequestResource
• GCSResource
• S3resource

Additionnal generic tasks

• Other VCS, like mercurial, …

Feel free to add your ideas/need in comment, I'll update this issue's description 😉
