semaphore-demo-ruby-kubernetes's Issues

Impossible to run any build correct

I tried to run the default repo https://github.com/semaphoreci-demos/semaphore-demo-ruby-kubernetes but nothing works lost several minutes trying to works but nothing happens.

The errors says:

This example should be running fine, but unfortunately no.
