asmtal / flaskweatherapp

A flask weather app deployed by me on Kubernetes and exposed using a service. Automated Jenkins servers on AWS for CI/CD Pipelines using Terraform and Ansible.

FlaskWeatherApp

• Developed a flask app using Python3, SQLalchemy and deployed it on Kubernetes.
• Used Jenkins servers on AWS for CI/CD pipeline.
• Provisioned the architecture on AWS using Terraform.
• Did configuratin management of Jenkins servers on AWS using Ansible.
• Deployed the app on EKS cluster using helm chart.

Steps to run the flask app

1. Clone the git repo.
2. Create a python virtual environement.
3. Install the requirements.txt in the environement.
4. Use the sample secret.ini provided below to run the app.

[main]
api_key = 271d1234d3f497eed5b1d80a07b3fcd1

5. Run the app using flask run command.

Steps to run Dockerfile

1. Clone the git repository.
2. cd in the repository and build the Dockerfile using docker build -t <name of image you want to build>:<tag> . (example - docker build -t weatherapp:1 .)
3. Check the images present using docker image ls
4. Run the Dockerfile using docker run -it -v <local-config-location>:<location-in-docker> -v <local-secret-location>:<location-in-docker> -p <port_to_be_served>:<port_the_website_works> <name of image you want to build>:<tag> (example - docker run -it -v ${PWD}/config:/config -v ${PWD}/secret/:/secret -p 5000:5000 weatherapp:1)
5. Go to localhost:5000
6. The docker image can be found on Docker Hub - https://hub.docker.com/r/jack17529/weather

Steps to deploy

1. Make a deployment.yaml file
2. The file has 2 parts the deployment part and the service part.
3. Make a namespace for the app kubectl create ns flaskapp
4. Deploy using kubectl apply -f deployment.yaml -n flaskapp
5. Check port31000 and the weather app would be running.

Setting up AWS

• Infrastructure provisioning with Terraform and configuration management with Ansible.
• Using aws-vault for keeping secrets.
• Steps are present here - https://github.com/jack17529/FlaskWeatherApp/tree/aws

Setting Jenkins Pipeline

• Set up jenkins pipeline with 3 jobs which are triggered from github webhook. Used Jenkins master and two slave servers on AWS.
• Tested the backend on staging server then deployed it in production using Jenkins Pipeline.
