How to send http request from Docker to localhost or Virtual Machine

Being new to Docker and VM’s, I have run into a blocker. I have a node app that needs to send a POST request from a Docker container to a Virtual Machine or to my local machine.

I have read through the Docker documentation, but still don’t understand what I need to do in order to accomplish this.

  • initdb: could not change permissions of directory on Postgresql container
  • docker multiple containers with static addresses
  • Copy directory before update and import after compile.
  • Trying to reach localhost from inside Selenium docker
  • Docker Swarm: Does it let two containers in different hosts to communictae?
  • docker out of disk space
  • So how can I send an http request from my node app running in a Docker Container to my Vagrant Box?

  • guacamole You do not have permission to access this connection"
  • Dockerhub Automatic Build with Github LFS
  • Gitlab run docker inside docker
  • Get audio from asterisk in docker on Mac?
  • How to set-up a docker registry acting as a Proxy?
  • Docker push re-sends layers to private repository

    By default, Docker creates a virtual interface (docker0) in your host machine with IP Each of the container launched will have an IP of the network, and they will be able to connect to host machine connecting to IP

    If you want to connect a docker container with another service running in a virtual machine running with other provider (e.g.: virtualbox, vmware), the easiest way is forwarding the ports needed by the service to you host machine and then, from your docker container, connecting to IP You should check your virtual machine provider documentation to see details about this. And if you are using libvirt/KVM (or with any other provider), you can use iptables to enable port forwarding.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
