Continuous deployment of Node.js application for Heroku using GitLab

Question

There are tutorials on deploying Ruby and Python applications, but I can't find good documentation or examples for NodeJS.

http://docs.gitlab.com/ce/ci/examples/test-and-deploy-python-application-to-heroku.html

http://docs.gitlab.com/ce/ci/examples/test-and-deploy-ruby-application-to-heroku.html

Does anyone have .gitlab-ci.yml to share?

Answer 1

I found a detailed article for continuous integration on Heroku:

https://medium.com/@seulkiro/deploy-node-js-app-with-gitlab-ci-cd-214d12bfeeb5

Example .gitlab-ci.yml file:

https://gitlab.com/seulkiro/node-heroku-dpl

Answer 2

1. create project

  npm init -y npm i #install dependencies 

2. add the following lines to package.json

  "engines": { "node": "8.12.0", //node version "npm": "6.4.1" //npm version }, "scripts": { "start": "node app.js", //heroku will using the following script to run node app } 

3. create a heroku project

   1. select NEW → Create New Application
   2. set the name of the application and select a region
   3. click on the Create Application button

4. Gitlab setup creates a new repo or adds to an existing project listed on the gitlab website

5. create the .gitlab-ci.yml file

    image: node:latest stages: - production production: type: deploy stage: production image: ruby:latest script: - apt-get update -qy - apt-get install -y ruby-dev - gem install dpl - dpl --provider=heroku --app=APPNAME_OF_Heroku App --api-key=$HEROKU_API_KEY # security add the heroku api to CI/CD setting only: - master #branch name to deploy on heroku 

6. Setting HEROKU_API_KEY
   1. Setup → CI / CD → Variable → Expand
   2. Input variable key -> variable name in .gitlab-ci.yml
   3. Input Variable Value → Heroku Api Key

7. Get Heroku Api Key

   4. Heroki Dashborad → Account Settings

8. install runner on gitlab
