Building Composite Docker Images
Query: Can Docker merge multiple images into a single one, combining their functionalities? For instance, creating an image that bundles Java and MySQL from individual images containing each component separately?
Solution:
Docker itself does not natively support image combination, but DockerMake, an external tool, enables this functionality. It leverages a YAML configuration file to define the dependencies and build instructions for each image component. Using DockerMake, you can create a composite image by inheriting from multiple base images.
For example, to construct an image with both Java and MySQL, you would define a DockerMake configuration similar to the one provided below:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |

With DockerMake installed (via pip), simply execute the command docker-make specificAB to build the desired composite image.
