Hi Guys,

On my Droplet, let’s say

i have IP ADDRESS: X.X.X.99
I assign a new floating IP address like: X.X.X.100

I would like to run two docker container like that

docker run –name mynginx1 -p X.X.X.99:80:80 nginx
docker run –name mynginx2 -p X.X.X.100:80:80 nginx

The second command is not working so far.

What should i do to make it work?

Thank you!

Antoine

Hi @antoine0148fdc88ebae8de13b

When using the Floating IP, the droplet is assigned an Anchor IP, which is the IP you should listen to.
Read more about Anchor IP here - and how to retrieve it:
