Recently, I was working on a micro-service using Ratpack framework. \u00a0I wanted to deploy it to Heroku. I had tried to find good documentation for deploying on Heroku but couldn’t find as such.\u00a0After much trial and error, I finally managed to get a working configuration for successful deployment. As Heroku has very good support for Gradle-based projects and just we need to give right configuration details and all would be done. So, Here are the steps for right configuration:<\/p>\n

Artifacts:\u00a0<\/strong>we would need to create some files at root of the project which would contain<\/p>\n

\u00a0 1. system.properties<\/span><\/em>: \u00a0It will let\u00a0Heroku \u00a0know which version of java to be used<\/p>\n

java.runtime.version=1.8<\/pre>\n
\u00a0 2. settings.gradle<\/span><\/em>:<\/p>\n
rootProject.name = 'project_name'<\/pre>\n
\u00a0 3. Procfile<\/span><\/em>: It would\u00a0let\u00a0Heroku know from where it needs to pick a big fat jar of the project and what command, it needs to execute to run project.<\/p>\n
web: java -jar -Dport=$PORT build\/libs\/project_name-all.jar<\/pre>\n
Edit build.gradle:\u00a0<\/strong>we would need to add a dependency \u00a0in buildscript for buildingfat jar<\/p>\n
buildscript {\r\n    repositories {\r\n        jcenter()\r\n    }\r\n    dependencies {\r\n        classpath \"io.ratpack:ratpack-gradle:0.9.15\"\r\n        classpath \"com.github.jengelman.gradle.plugins:shadow:1.2.1\"\r\n    }\r\n}\r\n\r\n<\/pre>\n
apply plugin: \"io.ratpack.ratpack-groovy\"\r\napply plugin: \"com.github.johnrengelman.shadow\"<\/pre>\n
and closure of Task stage<\/em>\u00a0:<\/p>\n
task stage {\r\n    dependsOn shadowJar\r\n}<\/pre>\n
This above code will help in generating big fat jar of ratpack application with name project_name-all.jar when Heroku would run “gradle stage” task for building the code.<\/p>\n
 <\/p>\n
Just That’s it…
\nNow! We are ready to commit our code to Heroku and deployment done \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
