I’m seeing a few unhappy comments about this, so I’ll just point out a couple of things:

1. This was introduced in a beta. It was then removed from subsequent betas until a fix could be found.

2. Running docker on a router could be really helpful in some cases, especially for small ISPs such as mine. For example: being able to run a recursive DNS resolver at the broadcast tower (ie nearer the customer) without having to run an entire server would be great. Or running a Prometheus exporter on the router for metric collection. Or for local processing/archiving of netflow data.

There are some really helpful use cases for this, but they are not the normal devops reasons for using docker.
