Pre-Requisites

Note: Steps 1-3 are only required if the repositories are still private

1. Generate SSH key for github authentication

   ssh-keygen -t ed25519 -C "[email protected]" -f ~/.ssh/id_github -q -N ""
   
   cat ~/.ssh/id_github.pub
   

2. Go to the Github Page

   • log into your account
   • on top right click your icon and choose "Settings"
   • click on "SSH and GPG Keys"
   • click on the button that says "New SSH key"
   • name it something appropriate
   • paste the contents of the cat ~/.ssh/id_github.pub command into the Key section on github
   • click "Add SSH key"

3. Copy your private ssh key into this repository

   cp ~/.ssh/id_github <path to this repository>
   

4. Install Docker and Docker compose using

   cd <path to this repository>
   sudo chmod +x install_docker.sh
   ./install_docker.sh
   

Install ECUI

Now you only need to execute the following script

sudo chmod +x install_ecui.sh
./install_ecui.sh

After executing the script login to Grafana (localhost:3000) once and then execute

sudo docker cp <path to this repository>/grafana/lib/grafana.db grafana:/var/lib/grafana/
sudo docker restart grafana

Configure Grafana

After copying the grafana database log into grafana again and head to "Configuration" (cogwheel on left sidebar) -> influx-streaming

Then enter the correct hostname port and database; probably:

• hostname: localhost
• port: 8086
• database: gse

Troubleshooting

• if the llserver fails to connect to the web server or carshes instantly try to check if the correct ip addresses are used in the config file with sudo docker network inspect bridge

• if either or both web and llserver refuse to start, try and check the docker environment variable for the correct config path

• if the llserver crashes instantly check if influx is correctly installed
