Copy content from Docker container

SYNTAX: docker cp SOURCE_PATH DESTINATION_PATH
docker cp CONTAINER_ID:FOLDER_PATH LOCAL_DESTINATION_PATH
example: docker cp 07gsbsdh4563:/app/sample.txt c:\sample_data\

Copy content from Local machine to Docker container

SYNTAX: docker cp LOCAL_SOURCE_PATH DESTINATION_PATH
docker cp LOCAL_DESTINATION_PATH CONTAINER_ID:FOLDER_PATH
example: docker cp sample.txt 07gsbsdh4563:/app/sample.txt

Execute command on docker container from your physical machine

Syntax: docker exec -it container_id command
example: docker exec -it 07gsbsdh4563 ls
