Class DefaultTransferFilesCreator

java.lang.Object

software.xdev.testcontainers.imagebuilder.transfer.DefaultTransferFilesCreator

All Implemented Interfaces:

TransferFilesCreator

public class DefaultTransferFilesCreator
extends Object
implements TransferFilesCreator

Helper class for copying the docker-context inside a container, based on a (.git-)ignore file.

This class only exists because TestContainers default .dockerignore resolver isn't working well: It's slow (needs ~30s) and works incorrectly/misses files.

Utilizes IgnoreNode for ignoring.
