问题
Some providers, such as ScaleWay will give your server an IP that is not attached to a local interface on the box.
# docker swarm init --advertise-addr <my-external-ip>:2377 --listen-addr 0.0.0.0:2377
Error response from daemon: must specify a listening address
because the address to advertise is not recognized as a system address
While
# docker swarm init --advertise-addr eth0:2377
will advertise a private IP address.
How is docker swarm supposed to be setup in such an environment?
回答1:
There is an issue with native swarm mode, when it comes to binding to a non system IP Address as docker 1.12.5. There has been multiple github issues, but the problem still persists.
To define non system IP Address: IP Addresses used with technologies like DNAT. These IP Addresses are not set on local interface and visible to underlying operating system.
