Kotlin + Spring + Vue: CI/CD

In this section,

we will overview how to automate the delivery process, configure a CI/CD pipeline, feel yourself a DevOps engineer and actually make development more enjoyable.

GitHub Repository

Create a git repository from project root folder. I recommend to create the following .gitignore file there first:

*.class

# Help #
backend/*.md

# Package Files #
*.jar
*.war
*.ear

# Eclipse #
.settings
.project
.classpath
.studio
target

# NetBeans #
backend/nbproject/private/
backend/nbbuild/
backend/dist/
backend/nbdist/
backend/.nb-gradle/
backend/build/

# Apple #
.DS_Store

# Intellij #
.idea
*.iml
*.log

# logback
logback.out.xml

backend/src/main/resources/public/
backend/target
backend/.mvn
backend/mvnw
frontend/dist/
frontend/node/
frontend/node_modules/
frontend/npm-debug.log
frontend/target

!.mvn/wrapper/maven-wrapper.jar

Make initial commit to your GitHub repository and make Push.

Heroku

IMPORTANT: Before you start Heroku configuration, add Procfile (with no any extension) to the root folder of your repository with the following string:

web: java -Dserver.port=$PORT -jar backend/target/backend-0.0.1-SNAPSHOT.jar

and commit!

OPTIONAL: Add also .travis.yaml file to reduce build and deploy time:

language: java
jdk:
- oraclejdk8
script: mvn clean install jacoco:report coveralls:report
cache:
directories:
- node_modules

#1 Register at Heroku

#2 Create an app:
