Rets Rabbit removes the nightmare of importing thousands of real estate listings and photos from RETS or ListHub and gives you an easy to use import and Web API server so you can focus on building your listing search powered website or app.
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.
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.
Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.
The list of actions listed below was taken mostly from Book Of Zeus with minor modifications and did the job well for Ubuntu version, which was available at that moment (May 2016). This gist was created for internal use and was never meant to be discovered by the web, although Google managed to find and index this page, which was a great surprise for me. Please check the original source for the updated information (links are provided in most of the sections), and read the comments below: they provide more details about the usage experience.

Keeping the system updated is vital before starting anything on your system. This will prevent people to use known vulnerabilities to enter in your system.
