Before, we did this in an init container, which meant if the Dex pod restarted we would have fresh certs, but our Tilt/bash setup didn't account for this. Now, the certs are generated by a Job which runs once and saves the generated files into a Secret. This should be a bit more stable. Signed-off-by: Matt Moyer <moyerm@vmware.com>
