    <outputDir>

Description

simpledsapp_moc.py is a ChRIS-based application that basically does an explicit copy of each file in an input directory to the output directory, prefixing an optional string to each filename.

Agruments

[--prefix <prefixString>]
If specified, a prefix string to append to each file copied.

[--sleepLength <sleepLength>]
If specified, sleep for <sleepLength> seconds before starting script processing. This is to simulate a possibly long running  process.

[--ignoreInputDir]
If specified, ignore the input directory. Simply write a single json  file to the output dir that is a timestamp. Useful if the input  directory contains large nested file trees.

[-v <level>] [--verbosity <level>]
Verbosity level for app. Not used currently.

[--version]
If specified, print version number.

[--man]
If specified, print (this) man page.

[--meta]
If specified, print plugin meta data.

Run

This plugin can be run in two modes: natively as a python package or as a containerized docker image.

Using PyPI

To run from PyPI, simply do a

pip install simpledsapp_moc

and run with

simpledsapp_moc.py --man /tmp /tmp

to get inline help. The app should also understand being called with only two positional arguments

simpledsapp_moc.py /some/input/directory /destination/directory

Using docker run

To run using docker, be sure to assign an “input” directory to /incoming and an output directory to /outgoing. Make sure that the $(pwd)/out directory is world writable!

Now, prefix all calls with

docker run --rm -v $(pwd)/out:/outgoing                             \
        fnndsc/pl-simpledsapp_moc simpledsapp_moc.py                \

Thus, getting inline help is:

mkdir in out && chmod 777 out
docker run --rm -v $(pwd)/in:/incoming -v $(pwd)/out:/outgoing      \
        fnndsc/pl-simpledsapp_moc simpledsapp_moc.py                \
        --man                                                       \
        /incoming /outgoing
