Tutorial explaining Docker + Python3 SharedMemory usage

Docker + SharedMemory = <3

Description

This is a simple example of how you can share memory blocks between containers using Docker and Python3 SharedMemory library.

Usage

Build with docker-compose

docker-compose up

Or alternatively (and with more work), build and run the transmitter and receiver individually:

Build transmitter image

docker build ./transmitter/ --tag "transmitter:shm"

Build receiver image

docker build ./receiver/ --tag "receiver:shm"

Run transmitter

docker run --ipc="shareable" [TRANSMITTER_IMAGE_ID]

Run receiver

docker run --ipc="container:[TRANSMITTER_CONTAINER_ID]" [RECEIVER_IMAGE_ID]
