Description
Description
When you create a service with a published port, this port is assigned to all host IPs (0.0.0.0). You cannot create a new service on the same port because this port is already in use.
This issue was first created in docker/swarm
Steps to reproduce the issue:
- docker service create --name test -p 192.169.2.8:80:80 nginx
and
- docker service create --name test -p 80:80 nginx
- docker service create --name test2 -p 80:80 nginx
Describe the results you received:
invalid argument "192.169.2.8:80:80" for p: HostIP is not supported by a service.
See 'docker service create --help'.
and
- 1wwed5dix1xga27583dh9bh6r
- Error response from daemon: rpc error: code = 3 desc = port '80' is already in use by service 'test' (1wwed5dix1xga27583dh9bh6r)
Describe the results you expected:
If a host has multiple IP addresses it should be possible to publish container ports on a specific IP address.
