Use Docker-Client Library to interact with a Docker Daemon

User Story: As a Plugin developer I want to access the Docker Deamon for building dockerfiles or starting containers

When trying to build Dockerfiles you have to access a running instance of the Docker Daemon. This decides how this will be done in the code.

Considered Alternatives

• Docker-Client Library: See Here
• Docker CLI Calls
• Manually Connect to the Docker Daemon

Decision Outcome

• Chosen Alternative: Docker-Client Library
• The Library is quite simple to use, and does allow the mocking of some parts. The maintainabiliy is also better, compared to the other options.

Pros and Cons of the Alternatives

Docker-Client Library

• + Allows Access to the Docker Daemon using method calls
• + Can be mocked (easier than the other options)
• '+' Allows the connection to other Docker daemons by changing the configuration of a client object
• - Not the best Documentation

Docker CLI Calls

• + The Quality of the Documentation depends on us.
• - Hard to maintain
• - Possible issues with platform independency
• - Connection to other Docker Daemons is hard

Manually Connect to the Docker Daemon

• - Highly Complex
• - Even harder to maintain
