robosapiensIO backend with Docker Tutorial

Goal: This tutorial will walk you through the steps to set up the robosapiensIO backend using Docker and Docker Compose. This can be used when manually running (e.g.using main.py) self-adaptive applications instead of the generated docker containers or for experimenting purpose.

Tutorial level: Beginner

Time: 5-10 minutes

Background

The robosapiensIO backend, used to develop and commission trustworthy self-adaptive systems using the RoboSAPIENS Adaptive Platform architecture, is provided as a multi-container Docker application. It includes the following services bundled in a Docker Compose configuration:

• EMQX Enterprise MQTT Broker

• Redis

A standalone robosapiensIO backend is provided for experimenting purposes or to run the self-adaptive applications in a manual way (e.g. using main.py).

Prerequisites

• Git: Make sure Git is installed on your machine. You can install it from Git’s official website.

• Docker: Make sure Docker is installed and running on your machine. You can install it from Docker’s official website.

• Docker compose: Make sure Docker compose is installed and running on your machine. You can install it from Docker’s official website.

Tasks

1. Clone the repository

   Open a terminal and run the following commands:

   git clone https://github.com/BertVanAcker/rpio-backend-docker.git
   cd rpio-backend-docker
   

2. Start the services using Docker Compose

   After pulling the git repository, you can run the robosapiensIO backend using docker compose command:

   docker compose up --detach
   

   Here’s what each flag does:

   • --detach: Runs the container in detached mode.

3. Verify that the services are running

   You can check that Redis Stack is running by connecting to it with the redis-cli:

   docker exec -it redis redis-cli
   

   Run a basic command to confirm connectivity, such as:

   PING
   

   If the response is PONG, Redis Stack is up and running.

   You can check that the EMQX MQTT broker is running by running the following command:

   docker exec -it emqx emqx ping
   

   If the response is pong, EMQX MQTT broker is up and running.

Summary

You have successfully set up robosapiensIO on Docker and is now ready to be used.
