+`kubevirt` publishes a containerdisk which can be consumed by KubeVirt. In order to publish the containerdisk, the
+credentials to the container registry need to be provided in `~/.docker/config.json`.
+
+An example configuration may look like this:
+
+```
+{
+ "auths": {
+ "quay.io": {
+ "auth": "dXNlcjpwYXNzCg=="
+ }
+ }
+}
+```
+
+where `auth` is a base64 encoded HTTP Basic Auth token:
+
+```
+$ echo dXNlcjpwYXNzCg== | base64 -d
+user:pass
+```
