Docker

• installation according to here with the convenience script (because of the comment regarding raspberry installation)

curl -fsSL https://get.docker.com -o get-docker.sh
DRY_RUN=1 sudo sh ./get-docker.sh
sudo reboot
sudo usermod -aG docker $USER // logout and login

• architecture is linux/arm64/v8
• edited /usr/lib/systemd/system/docker.service, saved the old version to ~/SoftwareProjects/eclipse-workspace/uweheuer-backend/docker.service.2023-01-07 to get rid of iptables error and missing dPort parameter when calling docker compose up for uweheuerbackend

Test by:

docker 
docker version
docker compose version
docker run hello-world

Portainer Community Edition (CE)

• according to here

mkdir ~/PortainerData
docker volume create portainer_data
docker run -d   -p 8000:8000 -p 9443:9443   --name portainer   --restart=always   -v /var/run/docker.sock:/var/run/docker.sock   -v portainer_data:/home/uwe/PortainerData   cr.portainer.io/portainer/portainer-ce:latest
