• What Operating System are you using (both controller, and any agents involved in the problem)?

Ubuntu 20.4

Reproduction steps

• Create a classic Swam manager endpoint on an ipv6 enabled docker host
• Create a classic Swarm agent on a separate ipv6 enabled docker host
• Launch a build job on the swarm endpoint (using jenkins) and check the port bindings
• Check the bindings in on the swarm manger node to be made available on ipv4 using different different ports, e.g.:
  • 10.10.1.11:49448->22/tcp, 10.10.1.11:49449->22/tcp

Results

Expected result:

• The agent should connect to any of the SSH bound ports

Actual result:

• The agent may never be started, because there are two SSH bindings of the container, but if the first one is the only one checked it may not respond correctly, but the second one does
