Docker Prep/Prerequesites (Debian)

This guide assumes you are running a Debian based OS.  So, it will work regardless of whether you are using Proxmox, OMV, Ubuntu Server, Linux Mint or anything else that uses APT.  If you are using some flavor of Arch, Fedora, FreeBSD or any of their derivatives, you'll have to use their version of these commands.  For example, Arch uses AUR.  I don't know what the others use.  I might change the guide to support other OSs, if I feel energetic enough.

Do note that you may want/need to alter the process quite a bit for stuff like Proxmox and OMV, since they use a GUI that is very different from a normal desktop/server distro like Mint or Ubuntu Server.  For example, you'll probably want to use a Docker LXC under Proxmox, rather than running Docker directly on the host OS.  For OMV, you'll have to decide whether to install everything directly from the command line (as this guide covers) or to install it from OMV-extras.  I do cover how to install OMV-extras in the OMV guide.

Install prereqs:

sudo apt update
sudo apt install apt-transport-https ca-certificates curl gnupg

Add Docker's Official GPG Key:  curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker.gpg

Add Docker Repo:  echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu jammy stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Refresh package list again:  sudo apt update

Install docker:  sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Verify:  sudo systemctl is-active docker

Add your user to Docker group:  sudo usermod -aG docker ${USER}

Reboot server for permissions to take effect or run this command:  newgrp docker

Verify docker access with:  docker ps

Install Portainer:

Create Docker Volume:  docker volume create portainer_data

Deploy Portainer:

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:/data \
  portainer/portainer-ce:latest

Connect to portainer "https://localhost:9443" and setup admin account.

Click Home -> Environments and add the host IP (10.20.10.75, for me) into the Public IP field.

Optionally, change Settings -> Settings -> Application Settings -> URL to https://raw.githubusercontent.com/technorabilia/portainer-templates/main/lsio/templates/templates-2.0.json
