Terraform

This directory contains the terraform code that allows to deploy the project to an aws EC2 instance.

Instructions

• Get into the terraform directory

      cd terraform

• Set your aws IAM credentials of a user with programmatic access.

      cp credentials.example credentials.sh
      ##Set your credentials in the created file
      chmod +x credentials.sh
      . credentials.sh

• Create your ssh key-pair

      ssh-keygen -t rsa -b 2048 
      ...
      Generating public/private RSA key pair.
      Enter file in which to save the key (/home/path_to_ssh/.ssh/id_rsa): /home/path/to/save/keys/aws_key 
      ...

Note

Change your own path in the line 27 of the main.tf and line 3 of the security.tf files.

• Start terraform

      terraform init

• Look the terraform plan and deploy

      terraform plan
      ...
      terraform apply
      ...

• Connect to the instance and check if the images are running

      ssh -i "your/private/key/path" ubuntu@your_instance_ip
      sudo docker ps -a
      ...

  If everything went right all the images should be shown by the last command.

Additional notes

Everything was done having in mind a free plan deployment, so the images of the project are in a docker repository, IMO the best way should be by creating the images directly in the EC2 instance, because with that way we can modify the .evn file of the web application so it sends the requests to the correct endpoint, but with a t2.micro is was impossible to build the images on the EC2 instance.
