Ansible / Jenkins / AWS Cloud /GitHub Webhook / Docker
CI/CD Pipeline to Automate Docker Image Build
This project shows how to automate the Docker image build process on every commit on the GitHub repo using Ansible. An Ansible playbook created will be triggered using github webhook which builds a Docker image from a Flask app repository, pushes it to Docker Hub, and runs it on a test server. Using this workflow, testing of applications can be done smoothly.
Docker / Nginx / IP-geolocation API / Redis
Dockerizing Your IP Geolocation Service with Nginx Reverse Proxy
This is a simple IP-location application project which you can deploy with the help of containerization. Also, this project includes 3 api containers for effectivly working and that can handle more clients, and these containers uses a common cache server (Redis). Also, an Nginx container acts as a reverse proxy, which receives traffic from the outside world and redirects it to the api containers.
AWS Cloud / Ansible / LAMP Stack
Launching a WordPress Website on LAMP Stack Across Different Operating Systems using Anisble Playbook
This project shows how to create an Ansible playbook that can be used to deploy a WordPress website on a LAMP stack, regardless of the target server’s operating system. This playbook can be used to run on servers running on Amazon Linux & Ubuntu AMI's.
