Test it has installed correctly by getting the docker version
I also install docker-compose as some dockers need you to compose from a yml file. This downloads v2.16.0, just change this if the version updates to a later version
sudo curl -L "https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
Give permissions to this
sudo chmod +x /usr/local/bin/docker-compose
Test it has installed correctly by getting the docker-compose version
I keep all my dockers in a dockers folder in my home directory. If it doesn’t exist already, create this folder:-
Now create a folder for NodeRed to live in.
We need to create a folder for NodeRed to store data in.
Change directory to this folder
Create a docker-compose.yml file
Paste the following.
version: "3.7" services: node-red: image: nodered/node-red:latest container_name: node-red environment: - TZ=Europe/London ports: - "1880:1880" volumes: - ./data:/data
Save the file with ctl + x, then y to save.
Run the docker-compose file with the following:-
docker-compose up -d
Launch a browser and go to http://serverip:1880
