Create New Antlet

Create new antlet using Ubuntu 18 KVM.
Very important, before starting we must create a Virtual NIC

Set Up Bridge Networking

ssh ubuntu@10.1.1.23
sudo apt-get update
cd /etc/netplan
sudo nano 50-cloud-init.yaml

network:
  ethernets:
    ens3:
      dhcp4: true
  ethernets:
    ens8:
      dhcp4: true
  version: 2

Close and save file with control-o => return => control-x

Run the netplan apply command to update the network.
Don’t need to restart antlet.

sudo netplan apply

Get the external ip address

Eeeeeek! Not to worry. We just need to find ens8 in the above response.

Install Docker Engine

We need to use Digital Ocean’s setup tutorial since the setup using the official docker setup doesn’t work.

sudo apt-get update

sudo apt install apt-transport-https ca-certificates curl software-properties-common

sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"

sudo apt update

apt-cache policy docker-ce
# confirm Installed: (none)

sudo apt install docker-ce

sudo systemctl status docker

Install Docker-Compose

We’re using the official Docker installation tutorial.

sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

Set permissions:

sudo chmod +x /usr/local/bin/docker-compose

Verify installation by checking version:

docker-compose --version
docker-compose version 1.21.2, build a133471

If using curl doesn’t work, try pip.

# install python3
sudo apt update
sudo apt install python3

# install pip3
sudo apt update
sudo apt install python3-pip

# install docker-compose
sudo pip3 install docker-compose

# confirm that docker-compose is installed
docker-compose --version
