Install Docker

Update the repo to get latest versions

sudo apt update

Install the latest version

sudo apt install

Set Docker to start on startup

sudo systemctl enable --now docker

Give your user permissions to docker, replacing user with your username

sudo usermod -aG docker user

Once you have run this command close and reopen your session if you accessing remotely. This is to apply the permissions in the above step

Test it has installed correctly by getting the docker version

docker --version

Docker Compose

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 "$(uname -s)-$(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

docker-compose --version

Install NodeRed

I keep all my dockers in a dockers folder in my home directory. If it doesn’t exist already, create this folder:-

mkdir ~/dockers

Now create a folder for NodeRed to live in.

mkdir ~/dockers/nodered

We need to create a folder for NodeRed to store data in.

mkdir ~/dockers/nodered/data

Change directory to this folder

cd ~/dockers/nodered

Create a docker-compose.yml file

nano docker-compose.yml

Paste the following.

version: "3.7"
    image: nodered/node-red:latest
    container_name: node-red
      - TZ=Europe/London
      - "1880:1880"
      - ./data:/data

Save the file with ctl + x, then y to save.

Run the docker-compose file with the following:-

docker-compose up -d

First run

Launch a browser and go to http://serverip:1880
