[helgi]

For now fetch the minio credentials from the API

Note: I can change it to to object-storage if someone points me to the doc what to use instead

is this going in for beta? object storage secret is not yet implemented in slugrunner

[helgi]

This can go into beta if I just keep it as minio-user which is what slugrunner expects based on what you said

[smothiki]

Also this requires a change in helm charts removing secret volume mount in controller rc

@helgi has this been tested?

[smothiki]

if this is going in we should hold off the current testing and wait for the new images

[arschles]

Looks like it's already merged :)

[helgi]

Already merged and master for it was already built https://travis-ci.org/deis/controller/builds/116716881
