I am configuring sentrifugo in a Docker container. I can't access the internet from my docker container. I am new to Docker. My host machine is running Ubuntu 14.04. Any suggestions?
Your container should access internet the same way. Please check your resolv.conf of container and network connective of docker host.

I need to access a service in a Linux docker container from a Windows docker container.
Setup:
Host: Windows 10 installed "Docker for Windows"
Linux Container: publish port 8080
Windows Container: access port 8080 of Linux container
Creating a shared network does not work: docker share network with windows and linux containers
Mixing Windows and Linux containers with docker-compose does not work, since platform is not supported anymore in docker-compose file: https://github.com/docker/compose/issues/5872
Am I missing something or is it not possible to access Linux container services from a windows container?
Host ip can change, so I need to pick IP address dynamically. I've found some solutions online for dockers running for Linux, but I can't find how to do it if you run docker container on Windows. Running it through docker compose file.
On a Windows 7 host, I have a Ubuntu guest inside virtualbox which runs a gitlab docker container. Inside the VM I can connect to the Gitlab inside the browser using localhost:80. How can I make the Gitlab reachable from the host?
So far I tried a port-forwanding in virtualbox which doesn't help. In my host with ipconfig, I see three IPs. One is the hosts public IP, the other two are the VirtualBox Host-Only Networks, which I can successfully ping.
I'm trying to use kvm in a Centos 6 docker container, via docker machine. My docker machine vm (vmware fusion based) supports nested VMs, but in my docker container I'm seeing:
modprobe kvm
FATAL: Could not load /lib/modules/4.1.12-boot2docker/modules.dep: No such file or directory
modprobe kvm_intel
FATAL: Could not load /lib/modules/4.1.12-boot2docker/modules.dep: No such file or directory
Any idea what I'm missing?
Docker isn't virtual machine. It is a way to package your application.
So I think that running KVM - Kernel Virtual Machine it is not possible inside docker container.
You can read about difference between Docker and other kind of virtualization on page:
https://www.docker.com/what-docker
you may need to load the kvm and kvm_intel module on the docker host before trying to run the container

You can use KVM simple container in DockerHub. Source code is available on GitHub and has been tested in DockerHosts with Ubuntu 16.04, Centos 7, Centos-Atomic 7.2 and RancherOS.
