{8.0.0-new} Deploying to Heroku

Heroku is a platform-as-a-service that allows applications to be quickly hosted in the cloud. The juneau-examples-rest-springboot project contains additional metadata files for quickly deploying and running the examples in Heroku using free services.

You'll need to sign up for an account on Heroku. Afterwards, you can go to the apps page to create a new application:

https://dashboard.heroku.com/apps

Click the New button to create a new app, give it a unique name:

https://dashboard.heroku.com/new-app

After clicking the Create app button, you should see this page:

https://dashboard.heroku.com/apps/juneau-examples-rest/deploy/heroku-git

For this example, we'll use the Heroku Git option for deploying our application. Follow the instructions for installing the Heroku CLI and logging into Heroku:

https://dashboard.heroku.com/apps/juneau-examples-rest/deploy/heroku-git

Next, run the following commands to cd into our Eclipse project and initialize it as a local git repo:

$ cd juneau-examples-rest-springboot/ $ git init

Output

$ cd juneau-examples-rest-springboot/ $ git init Initialized empty Git repository in /.../juneau-examples-rest-springboot/.git/

Next, run the following command to link our project to the Heroku app:

$ heroku git:remote -a juneau-examples-rest

Output

$ heroku git:remote -a juneau-examples-rest set git remote heroku to https://git.heroku.com/juneau-examples-rest.git

Next, run the following commands to add our files to the git repo and push to the Heroku master branch:

$ git add . $ git commit -am "Initial deploy" $ git push heroku master

Output

$ git add . master (root-commit) 7c94cb9] Initial deploy 123 files changed, 11986 insertions(+) Counting objects: 127, done. $ git commit -am "Initial deploy" $ git push heroku master Delta compression using up to 8 threads.

If no errors were shown, then our application should now be live. You can click on the Open app button to open the examples application in a browser:

If everything worked, your browser should now be loaded with our example REST app:
