Troubleshooting

Create box

This is how to install something in a VM and export it as a Vagrant box and use it locally.

First copy the Vagrantfile from below and change the box to the box you want as a base.

Run vagrant up to create the Virtual Machine and vagrant ssh to login.
On Windows you might have to put ssh.exe to your %PATH%. If you have installed git, you can use C:\Program Files\Git\usr\bin You can also login via Putty on host: "localhost", Port "2222", login: "vagrant", password: "vagrant".

Run commands on remote Docker host

This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.

Enable Docker Remote API

First be sure to enable the Docker Remote API on the remote host.

This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.

Start a VM with Docker with a simple command

This is how to easily setup a VM with Docker and Docker Remote API enabled.
We use VirtualBox, Vagrant and Docker for that.

First install VirtualBox https://www.virtualbox.org/wiki/Downloads
and Vagrant https://www.vagrantup.com/downloads.html

Run vagrant version to check that vagrant is correctly installed.

Save the Vagrantfile from this gist to a local directory.
