I've been working on the docker part, taking my lumps but not bringing it up, as it isn't perl proper. I had a setback with following outdated instructions on the first attempt. I found a nice fresh how-to-install-docker-on-linux, from 31 January 2023, and have made considerable progress, but I can't quite get to where I successfully pull files. Fuller story in readmores:
All these commands went off without complaint:
apt update apt-get remove docker docker-engine docker.io containerd runc apt-get update apt-get -y install ca-certificates curl gnupg lsb-release mkdir -p /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --d +earmor -o /etc/apt/keyrings/docker.gpg echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrin +gs/docker.gpg] https://download.docker.com/linux/debian $(lsb_release + -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/n +ull apt-get update apt-get install -y docker-ce docker-ce-cli containerd.io docker-compos +e-plugin systemctl start docker systemctl enable docker
Output for root:
root@mypi:~# docker info Client: ... Server: Containers: 0 ... WARNING: No blkio throttle.write_iops_device support root@mypi:~#
Looks all good. But then as pi, I failed:
root@mypi:~# exit logout $ which docker /usr/bin/docker $ docker info Client: ... Server: ERROR: permission denied while trying to connect to the Docker daemon +socket at unix:///var/run/docker.sock: Get "http://%2Fvar%2Frun%2Fdoc +ker.sock/v1.24/info": dial unix /var/run/docker.sock: connect: permis +sion denied errors pretty printing info $ whoami pi $
Then I thought, gosh, root can give pi permissions like this:
usermod -aG docker pi
, restart and see if I can pull some files:
$ docker info ... Server: Containers: 0 Running: 0 ...

I didn't understand this ultimate command, and I don't find any evidence of
on my machine./code
Q1) Do I need to be worried about this mismatch?
