Intro

This is simple flask application based on Python Flask Web framework which utilizes the app routes view functions as endpoints.

• App has three endpoints ,default,/health and /metadata

  • /

    • default

  • /health

    • would show status_code and message.

  • /metadata

    • Would show application metadata,version and github last commit.

CI/CD

• Configured Travis as CI/CD Pipeline for each commit on github.
• And also app to be built on python version 2.7 and 3.6.
• For each commit of the 2 parallel builds running for each of the python version.
• Travis pipeline script also builds docker image and runs the docker container .
• Runs unittest cases of the application

UnitTest

• I have used python unittest framework to develop the unit test cases for the above app to test endpoints and its data.

 python test.py -v

Depndencies

• I have packaged dependencies in requirement.txt file to install dependencies using pip before the app would executed.

Docker Build

• Containerized the flask app into single deployable artifact and its dependencies.

docker build -t flaskapp:latest .

Running Docker Container

• The below command would run the docker container which contains flask web application and runs on port 80.

docker run -d -p 80:80 flaskapp

• Once you have executed ,see the running container using below.

docker ps -a

Issues with healh end point -delay loading

• There is a delay in loading when we browse /health endpoint,becasue of the app is trying to point its own url and returing the status code . It tries to contact itself to find out the status of the app.
