Personal Blog

In this personal blog application, I will handle blog posts, my portfolio, as well as my professional online profile. It is developed following the Test-Driven Development principles, both unit tests and integration tests.

In the Makefile, you can find some automation of utilities for the backend:

    make migrations     # to make the migration files, and migrate them
    make user           # create a superuser in the database
    make test           # run tests with PyTest

Some of the most relevant technos I am using are the following, and some commands that are useful.

GitHub Actions

To automate the test on when pushing the code to the respository.

For the backend, it focuses on testing:

• Functionality: that the code is working well
• Code Quality: automating checks of the code quality and persistance with PEP8, as well as type hinting.

If we run this utility for GitHub Actions:

    gh run list

We will get an overview of all workflow we have defined, whether they are triggered via push, pull request, ...

Terraform

Infrastructure as a Code is a new way to create the cloud infrastructure. In this way, you define in code how the servers should be structured. For this, I am using Terraform for the automation & maintainance of the AWS cloud infrastructure.

For starting with it, we need first to download the necessary packages from the providers we are going to use:

    terraform init

This will install puligns to interact with the AWS API.

Another useful command:

    terraform plan

Will take a look to the code, and see which changes needs to be make. So it creates an execution plan. We could check if the configuration is valid with: terraform validate.

And to apply this execution plan:

    terraform apply

Once applied, we can check the status of our infrastructure with: terraform state list. We could add the tag: --auto-approve to automatically create it, without asking in terminal for confirmation.

In case we wanted to destroy the instances:

    terraform destroy

Docker && AWS

I am using Docker to containerize my application, so it can be easily deployed on a server EC2 in AWS. The simple CI/CD pipeline will be the following when pushing to main branch:

1. Making Integration test with GitHub Actions
2. Creationg of Docker image with GitHub Actions
3. Pushing Docker image to ECS of AWS
4. Deploy the image from ECS to EC2
