Signup for Google cloud platform

  1. Log on into the GCP, create an instance
  2. Under machine type choose micro (1 shared vCPU) this is the free option because they offer 300 credits annually
  3. Under boot disk choose the operating system you would like to use, using debian 9
  4. Allow default access under access scopes
  5. Under firewall choose the traffic option you need (or both if you are not sure) then create.

Accessing VPC instance
Use Putty or any other SSH tool to login in to the instance you created. You will find the external IP address information from GCP and fill in the information to Putty then add your private key to the configuration and SSH into your instance.

Point to Note: *whatever name is in the private key comment section will be used by google as the login account name, so change it to any name you rather use to login in such as foo.bar

Installing Docker
After successfully SSHing into the new VPC, run these commands to install Docker
Run these commands as root:

sudo -i

apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys F76221572C52609D

apt-get update

apt-get install apt-transport-https

echo "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | tee -a /etc/apt/sources.list.d/docker.list

apt-get update

apt-get install docker-ce

systemctl enable docker; systemctl start docker


As a regular user configure docker:

sudo usermod -aG docker $USER # log out/in to get new group

mkdir blog
