Help:
    Typical workflow scenario is (see also target descriptions bellow):

    1. Open terminal, run 'make ${RUN_OPENSEARCH}' .
    2. Open another terminal, run 'make ${RUN_DEV_ENV}' .
    3. Develop and build some great stuff.
    4. Close both terminals, run 'make $(CLEAN_ALL)', get some sleep.

    For other scenarios, run 'make <target>' where <target> is:
    - '${RUN_OPENSEARCH}' -- run OpenSearch containers.
    - '${RUN_DEV_ENV}' -- run /bin/bash in a development environment from Dockerfile.
    - '$(CLEAN_CONTAINERS)' -- clean docker containers.
    - '$(CLEAN_VOLUMES)' -- clean OpenSearch docker volumes, the containers
       have to be removed first.
    - '$(CLEAN_ALL)' -- clean all, docker containers and volumes.
