This is the steps we will take after we make any new VMs to ensure they are ready to run docker compose and will have a static ip.

Assigning a static IP

We can do this with Netplan. The process goes like this.

First create a backup of the netplan configuration.

sudo cp /etc/netplan/*.yaml /etc/netplan/backup.yaml

Open the configuration with nano

sudo nano /etc/netplan/50-cloud-init.yaml

Replace the configuration with the following, inputting the desired IP

network:
  version: 2
  ethernets:
    ens18:
      dhcp4: no
      addresses:
        - 192.168.4.50/22 
          # or any other desired address, this is just a template
      gateway4: 192.168.4.1
      nameservers:
        addresses:
          - 1.1.1.1
          - 8.8.8.8

Test it out before applying

sudo netplan try

Try pinging the IP from another VM or LAN device, if it works apply changes with the enter key.

Installing Docker and Docker Compose

Do sudo apt update && sudo apt upgrade first

Install prerequisites

sudo apt update
sudo apt install -y ca-certificates curl gnupg lsb-release

Add Docker’s official GPG key

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

Add Docker’s official repo

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

Install Docker + Compose (v2)

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Verify:

docker --version docker compose version

Enable docker without sudo takes effect after logging out and back in

sudo usermod -aG docker bryce

Start docker daemon

sudo systemctl enable --now docker
sudo systemctl status docker --no-pager -l
