# Jenkins CI/CD Pipeline to host Flask Application
### Github Actions
- This code check if there are any conflicts to merge with master branch
- If any problem persists it would break the pipeline and there would be no build triggered
- If the build fails there would be no build made and hence it won't be deployed and deployed build be a previous successfull build
```

### Jenkinsfile file to do stage work
- Once build in get sucessfull by scm poll in jenkins configuration the stage work gets triggered.
- Changes made by developer would be shared to hosted directory and hence it would apply changes in deployment.
