Make container accessible only from localhost

Question

I have Docker engine installed on Debian Jessie and I am running there container with nginx in it. My \"run\" command looks like this:

docker run -p 1234:80          


        

Answer 1

Specify the required host IP in the port mapping

docker run -p 127.0.0.1:1234:80 -d -v /var/www/:/usr/share/nginx/html nginx:1.9

If you are doing a reverse proxy, you might want to put them all on a user defined network along with your reverse proxy, then everything is in a container and accessible on their internal network.

docker network create net
docker run -d --net=web -v /var/www/:/usr/share/nginx/html nginx:1.9
docker run -d -p 80:80 --net=web haproxy

Answer 2

Well, solution is pretty simple, you just have to specify 127.0.0.1 when mapping port:

docker run -p 127.0.0.1:1234:80 -d -v /var/www/:/usr/share/nginx/html nginx:1.9
