bioreactor-docker

This project is the dockerization of Hackuarium/nodered-bioreactor-gui.

Install docker

curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-\$(uname -m) -o /usr/local/bin/docker-compose

Starting the project

Once you cloned the project, you can simply go to the folder and run:

docker-compose up

Stopping the project

You might want to do this if you pull some changes from the cloud, then start again.

docker-compose down

Docker images

We had to install three different docker images in the project:

Node-red
Mosquitto
InfluxDB

The images are installed (or built) thanks to the configuration in the docker-compose.yml file. The images were found on Docker Hub.

Node-Red

Source image: nodered/node-red

The node-red image has to be built because we add some packages to it (all the dependencies of the nodered-bioreactor-gui). All the packages are added in the filenode-red/Dockerfile`.

Mosquitto

Source image: eclipse-mosquitto

InfluxDB

Source image: influxdb

The node-red graphical interface of the bioreactor requires some influxDB databases to be already existing. We create these databases, as well as the continuous queries in the file influxdb/init/startup.iql.

The data of the database is in influxdb/db/.

Connect to influxdb for debug:

docker-compose exec influxdb bash

Deployment machine

Docker folder

Docker is in /usr/local/docker. This is where the project is cloned.

Proxy

Apache was used.

There is only one port accessible from the internet: HTTPS - port 443. Many services, which work on various ports, run behind this one entry point. This is why you have to configure a proxy, which will redirect queries to the correct services. In our case, we want to redirect [https://bioreactor.hackuarium.org]() to [http://localhost:1880]().

The proxy config file is: etc/httpd/conf.d.

The code underneath is what should be used as the configuration of port 443:

<VirtualHost *:443>
    Use SSLConf bioreactor.hackuarium.org

    ServerName bioreactor.hackuarium.org

    ProxyRequests Off
    ProxyPreserveHost On

    RewriteEngine On
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteRule /(.*) ws://localhost:1880/$1 [P,L]

    ProxyPass           /   http://localhost:1880/
    ProxyPassReverse    /   http://localhost:1880/
</VirtualHost>
