Class FlinkDistributionOverlay

java.lang.Object

org.apache.flink.runtime.clusterframework.overlays.FlinkDistributionOverlay

All Implemented Interfaces:

ContainerOverlay

public class FlinkDistributionOverlay
extends Object

Overlays Flink into a container, based on supplied bin/conf/lib directories.

The overlayed Flink is indistinguishable from (and interchangeable with) a normal installation of Flink. For a docker image-based container, it should be possible to bypass this overlay and rely on the normal installation method.

The following files are copied to the container: - bin/ - conf/ - lib/ - plugins/

addPathRecursively

protected void addPathRecursively(File sourcePath,
                                  org.apache.flink.core.fs.Path targetPath,
                                  ContainerSpecification env)
                           throws IOException

Add a path recursively to the container specification.

If the path is a directory, the directory itself (not just its contents) is added to the target path.

The execute bit is preserved; permissions aren't.

Parameters:

sourcePath - the path to add.

targetPath - the target path.

env - the specification to mutate.

Throws:

IOException
