GitLab Spring-Boot Heroku Continuous Integration and Deployment – part 1

Posted on by

Gitlab has in built pipeline for continuous integration and deployment. For every commit to the master branch , Gitlab CI will build and deploy my code to two(dev and staging) different Environments.

Prerequisites 

  1. Gitlab free account https://gitlab.com/
  2. Heroku free account https://www.heroku.com

 

Below is the .gitlab-ci.yml I use to build and deploy the application dev and staging environments

before_script:
 - echo "Execute scripts which are required to bootstrap the application. !"

after_script:
 - echo "Clean up activity can be done here !."
 
cache:
 paths:
 - /root/.m2/repository
 
stages:
 - build
 - deploy

build:
 stage: build
 image: maven:3.3.9-jdk-8
 script:
 - mvn clean package
 tags:
 - docker
 
deploy_dev:
 stage: deploy
 image: ruby:2.3
 script:
 - apt-get update -qy
 - apt-get install -y ruby-dev
 - gem install dpl
 - dpl --provider=heroku --app=vel-ci-api-dev --api-key=$HEROKU_API_KEY
 environment:
 name: dev
 url: https://vel-ci-api-dev.herokuapp.com
 only:
 - master
 tags:
 - docker
 
deploy_staging:
 stage: deploy
 image: ruby:2.3
 script:
 - apt-get update -qy
 - apt-get install -y ruby-dev
 - gem install dpl
 - dpl --provider=heroku --app=vel-ci-api-stg --api-key=$HEROKU_API_KEY
 environment:
 name: staging
 url: https://vel-ci-api-stg.herokuapp.com
 only:
 - master
 tags:
 - docker

I have two stages , build and deploy

build stage has only one job – build

deploy stage has two jobs – deploy_dev , deploy_staging

pipe-line-success

Pipeline-stages-builds

All the jobs in the same stage will be run parallel.

Below are the environments it gets deployed the application.

  1. Hello,
    First of all thanks for creating this article on this subject.
    I am trying to deploy a SpringBoot app (generating a RESTful API connected to a PostGreSQL database) using Gilab and Heroku (which are fairly new frameworks for me).
    Concerning your article i have a question about the variable here $HEROKU_API_KEY.
    Could you explain how and where you define that variable ?
    Regards

  3. Hi Vel,
    Thank you very much for this great article. But I have a couple of questions.
    1) my first question is about the runners, it looks like you didn’t register any runners. How does that possible ? Can you explain that part please ?

    2) my second question is about RUBY, you used image ruby in the deploy_dev and staging jobs, why did you use Ruby, is there another one that we can use ?

    Thanks in advance for your reply.
    Best

    • If you have a repo in gitlab.com , by default runners are enabled. If you have your own gitlab server , then you need to install and configure the runners.
      2. As i am deploying my spring boot application into Heroku , I need ruby packages. As per your deployment requirement, you can use any images that fits your needs.
      Hope this clarifies your question!.
