With docker already installed, following the instructions to create new user, that user needs to be manually added to docker group

[Dowster64]

Just a heads up, and I haven't got the l99 example running again yet but in the instructions it may be necessary to include instructions to add this new user to docker group?
Thanks,

@Dowster64, how did you install Ladder99 and Docker?

We have a script to install Docker, although I usually do it this way on Debian-like distributions:

non_root_user='user'

# Update the `apt` package index and install packages to allow `apt` to use a repository over HTTPS
sudo apt-get -y install ca-certificates curl gnupg lsb-release

# Add Docker's official GPG key
sudo mkdir -m 0755 -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

# Use the following command to set up the repository
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Update repositories
sudo apt-get -y update

# Install Docker Engine, `containerd`, and Docker Compose
sudo apt-get -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Add non-root user do `docker` group
sudo usermod -aG docker "$non_root_user"

Either way, the user should be added to the docker group. If you chose to install Docker differently, you need configure it manually (incl adding a non-root user to the docker group). Therefore, I am closing this as a non-issue. Feel free to re-open it if I didn’t got you.

It is possible though that you are following the installation guide at docs.ladder.99.com. It might need some cleanup.

@ottobolyos I was indeed following the installation guide on the docs. I had docker installed anyway on my pi as I have a framework set up for Industry 4.0 support which is docker based. I had problems with time and wanted to start afresh so I thought I ought to revisit my installation - which I had to do as I did update via git and it broke the last install... (see my real bug!). I did manually add the new user to the docker goup. I just wanted to ask if the documentation could mention this (as you picked up - thankyou)
