Hello World!

The purpose of this repo is to test deployment with the simplest possible node.js app.

Run it:

git clone git@github.com:nelsonic/hello-world-node-http-server.git && cd hello-world-node-http-server
npm start

Visit: http://localhost:3000 in your web browser.

You should see:

That's it!

Why?

This app was/is used to test our "ACID" deployment process. see: https://github.com/dwyl/learn-devops/issues/24

Automated Continuous Integration Deployment (ACID) MVP

1. Get Branch Issue Number

See: branch.sh e.g: 42

2. Create Dokku App

create the Dokku app for the issue number:

ssh root@138.68.163.126 dokku apps:create <appname>

e.g:

ssh root@138.68.163.126 dokku apps:create $(sh ./issue.sh)

Or for the master:

ssh root@138.68.163.126 dokku apps:create hello-world-node

3. Add Git Remote

git remote add dokku dokku@138.68.163.126:$(sh ./issue.sh)

3.b

Delete the remote

git remote rm dokku

Master:

git remote add dokku dokku@138.68.163.126:hello-world-node

4. Git PUSH Branch to Remote

git push dokku $(sh ./branch.sh):master

5. Add SSL Cert to App

Add the wildcard Cert to the Newly Created App

ssh root@138.68.163.126 "sudo dokku certs:add $(sh ./issue.sh) < /etc/letsencrypt/live/ademo.app/certs.tar"

ssh root@138.68.163.126 "sudo dokku certs:add hello-world-node < /etc/letsencrypt/live/ademo.app/certs.tar"

6. Reload nginx

ssh root@138.68.163.126 "nginx -t && nginx -s reload"

Add Dokku User on Server:

If you are using Dokku to deploy your app, run the following command on your server instance:

ssh root@138.68.163.126
cat ~/.ssh/id_rsa.pub | sudo sshcommand acl-add dokku root
