How to restrict droplet to only accept connections over private IP

I see that each droplet has a publiv IPv4 adress and a private VPC adress. How can I easily configure an Ubuntu docker droplet to only accept connections from within the VPC (i.e. via the private IP)?

Hello @mattiaswelander

I believe with a docker container this can be easily achieved by specifying localhost in the required host IP when you spin the container.

An example is docker run -p

This should do the trick for you.

Hope that this helps!

If you wish to use UFW, you can check this one out:
