CI-CD Pipeline for Nodejs, Circle CI, Heroku

This demo is practical demonstration of dockerizing app, continous integration using circle ci and deploy on heroku.

Flow of a process

A picture is a graphical representation how git is integrated with circle ci and deploy built and tested image to heroku.

SETUP

• (Create a new project from template)
• Auth with CircleCI
• Pick project from list
• Docker account & Heroku account & app configured
• Set up environment values:
• $DOCKER_LOGIN
• $DOCKER_PASSWORD
• $HEROKU_APP_NAME
• $HEROKU_API_KEY
• $SNYK_TOKEN

Pipeline Behavior on Triggering on code commit by Developer/Tester

• On the Failure of Test pipeline failed and stop further execution as shown below:

• After Fixing the Tests pipeline runing for approval by authorized person for deployment as shown below:

• Pipeline succeeded and after build and test process image from dockerhub is deployed on Heroku server as shown below:

These workflow images can be really helpful for learner to know about how the whole pipeline process is executed.

Hope this will be good learning guide.
