# Docker-Flask-Demo
Building a python-flask app image with Docker and pushing to Dockerhub using Jenkins CI/CD
## To run/test the app manually on an ubuntu/debian server:
- Install python3, pip3 & flask
- $ git clone https://github.com/Lily-G1/docker-flask-demo/
- $ cd docker-flask-demo
- $ python3 app.py
- View application on localhost/IP:8080
## To containerize the app using Docker:
- Install Docker
- $ cd docker-flask-demo
- $ docker build -t flask-app . (to build image)
- $ docker run -d -p 8080:8080 flask-app (to run container)
- $ docker stop 'container-ID' (to stop container)
## To containerize & push app to Dockerhub with Jenkins:
- Install Jenkins on same server. See installation guide [here](https://www.jenkins.io/doc/book/installing/linux/#debianubuntu)
- On the Jenkins U.I, go to Manage Jenkins -> Credentials -> global -> Add Credentials :
- Kind = ‘username & password’-> Enter your dockerhub account's username & password respectively
- Id = ‘dockerhub’
- Description = ‘dockerhub_credentials’. Save.
- Go to dashboard & create new item (pipeline project) -> Advanced Project Options -> Advanced -> Display Name = ‘Docker-Flask-App’
- Pipeline -> Pipeline SCM (enter github repo details). Save.
- Go to Manage Jenkins -> Manage Plugins -> Install ‘safe restart’ plugin
- On the server's command line:
- $ sudo usermod -a -G docker Jenkins. Log out & Log back in (to give Jenkins access to Docker)
- Restart Jenkins using systemctl on the command line OR via the U.I using 'safe restart'
- Build project
- Check Dockerhub to confirm that image was pushed successfully
## Note:
- Edit the image name on the Jenkinsfile to your preference
