Prompt admin users to assign a hostname to a Docker node only known by IP address

[itzg]

Rather than present connection addresses with IP addresses (of the Swarm nodes, for example), the UI should somehow prompt an admin user to assign a resolvable hostname for that IP address.

A reverse DNS lookup could be attempted, but that mechanism is not very reliable where the containers are run in one hosting provider and domain names managed by another.

So, a human-intervention solution is needed:

One way could be to show a pop-up in the main container listing for server addresses only known with IP address.

There could also be an option to pre-configure IP to host mappings.

• Mechanism to input IP to host mapping
• Display resolved host names in connection details
• Include resolved host name in copied value
