The project is a part from Udacity Nanodegree. In this project, it is required to apply the skills and knowledge obtained from the program, which includes:
- Worked with AWS
- Used CircleCi to implement Continuous Integration and Continuous Deployment (CI/CD)
- Built pipelines in CircleCi
- Used Ansible and CloudFormation to deploy clusters
- Built Kubernetes clusters (AWS EKS)
- Built Docker Images in pipelines (Dockerhub)
The CI/CD pipeline for microservices applications is developed with rolling deployment. Linting is also done to check typographical errors.
