simpleservice:0.5.0 doesn't work

[namanrawal47]

When I try to run this image from Quay, I get an Error: ImagePullBackOff. I do not have the same problem with centos:7. More info:

Failed to pull image "quay.io/openshiftlabs/simpleservice:0.5.0": rpc error: code = Unknown desc = failed to pull and unpack image "quay.io/openshiftlabs/simpleservice:0.5.0": failed to resolve reference "quay.io/openshiftlabs/simpleservice:0.5.0": failed to do request: Head https://quay.io/v2/openshiftlabs/simpleservice/manifests/0.5.0: x509: certificate signed by unknown authority
