Description of problem:

When uploading local source code using the "streaming" method (default), the build fails changing file ownership permissions for the uploaded source code.

Workaround: TBD

Prerequisites (if any, like setup, operators/versions):

shp CLI v0.16.0
Builds for OpenShift 1.6
OpenShift Pipelines 1.20
OpenShift 4.19

Steps to Reproduce

1. Create a build that uses the Git source ("test-build"). Use any build strategy.
2. Clone the same source code locally to your machine. Make a local change.
3. Upload the local source code using the shp command line:

shp build upload test-build .

Actual results:

Build fails changing the UID/GID of the local source code to match that of the running container:

tar: frontend/webpack.prod.js: Cannot change ownership to uid 103223, gid 103223: Operation not permitted
tar: shipwright/quizap/backend-build.yaml: Cannot change ownership to uid 103223, gid 103223: Operation not permitted
tar: shipwright/quizap/frontend-build.yaml: Cannot change ownership to uid 103223, gid 103223: Operation not permitted

Expected results:

Build succeeds uploading local source code.
