This project is for my master thesis about DevOps: Implemetation of CI/CD for container based applications at the FOM Dortmund.

The complete thesis can be downloaded here.

It contains a Phoenix Framework based project that is build by Circle CI and automatically deployed to AWS, with the following features:

• Static code analysis, formatting checks and test for every commit using GitHub actions
• Cirlce CI pipeline with various tests for every pull request
• Automatic serverless deployment using AWS Fargate and terraform
• Automatic preview environments for pull requests
• Automatic cleanup of preview environments when pull requests are closed or merged
• Automatic deployment into production for merged pull requests

The workflow for the CI/CD pipeline is:

Getting started

A Linux OS is the recommended environment for running this application.

Install Docker and asdf and execute the following plugins:

# Elixir/Erlang
apt-get -y install build-essential autoconf m4 libncurses5-dev libwxgtk3.0-dev libgl1-mesa-dev libglu1-mesa-dev libpng-dev libssh-dev unixodbc-dev xsltproc fop
asdf plugin-add erlang
asdf plugin-add elixir

# NodeJS
apt-get install dirmngr gpg
asdf plugin-add nodejs

# Add the following to your ~/.bashrc to make global package installation work
export PATH=$PATH:/usr/local/lib/npm/bin

# Terrform
asdf plugin-add terraform

# While being the application main folder run this install the versions specified in the .tool-versions file:
asdf install

Running locally

You can set up the application by running the following make commands:

make setup
make run

Now you can visit localhost:4000 from your browser.

Running in docker

To build a docker image and run it you can use this commands:

make docker
make run_docker
