Whale_Watcher

A rudimentary Python tool used to manage the execution of software within Docker containers on a single machine. This is done in an encapsulated manner, allowing multiple containers to be run simultaneously and independently. See ARCHITECTURE.md for my thoughts on tradeoffs when implementing this tool under a 3 hour time constraint.

Requirements:

1. Accept a bash command.
2. Launch a Docker container to run the command.
3. Collect logs real-time (STDOUT/STDERR) while the command runs.
4. The logs should be saved and identifiable in a logs directory.
5. Clean up when the command finishes and handle expected failures.
6. Have the ability to stop a specified container (without losing any logs).

Usage

• Make the file executable

chmod +x <script_name>

• Run some command inside a container

./script_name -r 'my command'

• To have more control over bash and run longer commands

./script_name -b 'my super long command with -options'

• To stop a specified container

./script_name stop 'container_name_or_id'

• To kill a container

./script_name kill 'container_name_or_id'
