Local run

1. Open terminal.
2. Go into bloomon-code-challenge folder.
3. You will need to install python 3.7.0.
4. Run:

   python script.py
   

5. In current (bloomon-code-challenge) folder you will see new file output.txt. It will contain results for this test task.

You can specify input file name and output file name by passing following flags:

• --input-file-name for input file name (default is sample.txt);
• --output-file-name for output file name (default is output.txt);

So, you can run following command:

python script.py --input-file-name another_sample.txt --output-file-name another_output.txt

Run in Docker

I tested this program on MacOS and I'm not sure how it will work on Windows, for example.

1. Open terminal.
2. Go into bloomon-code-challenge folder.
3. Run:

   docker build . --tag bloomon:oleh
   

   It will create docker image.
4. Run:

   docker run -it --name bloomon-code-olehzorenko --mount src="$(pwd)",target=/app,type=bind bloomon:oleh
   

   It will run container, mount volumes and execute program for this test task.
5. In current (bloomon-code-challenge) folder you will see new file output.txt. It will contain results for this test task.

In Docker you also can specify input file name and output file name by passing following flags:

• --input-file-name for input file name (default is sample.txt);
• --output-file-name for output file name (default is output.txt);

So, you can run following command:

docker run -it --name bloomon-code-olehzorenko --mount src="$(pwd)",target=/app,type=bind bloomon:oleh --input-file-name another_sample.txt --output-file-name another_output.txt

In this case, please, remember that you already have container with bloomon-code-olehzorenko name and if you need to run it again with file names flags, change the name of the container by setting --name flag to another name, for example --name bloomon-code-olehzorenko-with-flags.
