PERSONAL PROJECTS
Kubernetes Project
Deployed a JavaScript example web application to a local Kubernetes cluster using Minikube. Application is connected to a MongoDB database with Mongo Express for DB UI.
Docker Project
Built a Docker image for example JavaScript application. The application uses a MongoDB database and Mongo Express for DB UI, both containerized. Pushed image to a private repository on AWS ECR. Deployment simulated with pulling the app image from Amazon ECR and MongoDB and Mongo Express from DockerHub. After that, the app is being run with Docker Compose.
Jenkins Project
?Created a Jenkins instance where agents get dynamically created in containers only when a pipeline is being executed. After the pipeline is finished, agents are destroyed in order to free up resources.
