Init could not choose ip address error while doing docker swarm init

Question

I've recently started learninf docker swarm and i was experimenting while i came across the following error

Error response from daemon: could not choose an IP address to advertise since this system has multiple addresses

command that caused this error:

docker-machine create -d virtualbox node-1
docker-machine create -d virtualbox node-2
docker-machine create -d virtualbox node-3

eval $(docker-machine env node-1)

docker swarm init \
    --secret my-secret \
    --auto-accept worker \
    --listen-addr $(docker-machine ip node-1):2377

Whats happening?

Answer 1

First look for the public IP of your machine on your network

ifconfig

Add the IP address to your init statement like this:

docker swarm init --advertise-addr 192.1.68.1.x
