Self AWS cloud hosted setup example

In this guide we install, setup and run a postgsail project on an AWS instance in the cloud.

On AWS Console

Launch an instance on AWS EC2 With the following settings:

  • Ubuntu

  • Instance type: t2.small

  • Create a new key pair:

    • key pair type: RSA
    • Private key file format: .pem

  • The key file is stored for later use

  • Allow SSH traffic from: Anywhere

  • Allow HTTPS traffic from the internet

  • Allow HTTP traffic from the internet

Configure storage: The standard storage of 8GiB is too small so change this to 16GiB.

Create a new security group

  • Go to: EC2>Security groups>Create security group Add inbound rules for the following ports:443, 8080, 80, 3000, 5432, 22, 5050
  • Go to your instance>select your instance>Actions>security>change security group
  • And add the correct security group to the instance.

Connect to instance with SSH

  • Copy the key file in your default SSH configuration file location (the one VSCode will use)
  • In terminal, go to the folder and run this command to ensure your key is not publicly viewable:
chmod 600 "privatekey.pem"

We are using VSCode to connect to the instance:

  • Install the Remote - SSH Extension for VSCode
  • Open the Command Palette (Ctrl+Shift+P) and type Remote-SSH: Add New SSH Host:
ssh -i "privatekey.pem" ubuntu@ec2-111-22-33-44.eu-west-1.compute.amazonaws.com

When prompted, select the default SSH configuration file location. Open the config file and add the location:

xIdentityFile ~/.ssh/privatekey.pem

Install Docker on your instance

To install Docker on your new EC2 Ubuntu instance via SSH, follow these steps:

Update your package list:

sudo apt-get update

Install required dependencies:

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

Add Docker’s official GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

Add Docker’s official repository:

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update the package list again:

sudo apt-get update

Install Docker:

sudo apt-get install docker-ce docker-ce-cli containerd.io

Verify Docker installation:

sudo docker --version

Add your user to the docker group to run Docker without sudo:

sudo usermod -aG docker ubuntu

Then, log out and back in or use the following to apply the changes:

newgrp docker

Now you can follow the Postgsail process.
