Document recommendation to use IPv6 to download images from Docker Hub
It's very easy to run into rate-limits of the Docker Hub.
Fortunately, docker.io is available over IPv6, so an easy way to mitigate the rate-limiting is to use IPv6.
By default, G5K nodes don't have IPv6 enabled. The user needs to run dhclient -6 br0
.
Actionable items:
- add general documentation recommending IPv6 when downloading container images (applies to all providers)
- add specific dhclient command to all Docker-related examples for G5K
