Staged Deployment Example

Created using Heroku Django Template

Example Instructions

Create Project Locally and Push to GitHub master branch

Python, pip, and Django should be installed globally, as well as Heroku Toolbelt installed and authenticated. Create a GitHub repo and clone locally, but do not cd into the directory. Run this command in the parent directory (You can replace "projectname" with your desired project name; replace repo-name with the name of the GitHub repo you have cloned locally.):

$ django-admin.py startproject --template=https://github.com/heroku/heroku-django-template/archive/master.zip --name=Procfile projectname repo-name

Change directory

$ cd repo-name

At this point, it's strongly recommended that you create and activate a virtualenv of some type. Afterward, install requirements, and run server. (migrate?)

$ pip install -r requirements.txt
$ python manage.py runserver 

Check that the Django welcome page appears

http://127.0.0.1:8000

Add and commit files, with message

$ git add -A
$ git commit -m "Message"

Push to GitHub master branch

$ git push origin master

Deploy to Heroku Staging and Production Websites

$ heroku create app-name
$ git push heroku master

Migrate and Open Heroku App in Browser

$ heroku run python manage.py migrate (does this need to be run again for forked app?)
$ heroku open 

Fork the App

$ heroku fork --from app-name --to app-name-staging

Add Forked Remote

$ heroku info -a app-name-staging
$ git remote add forked [email protected]:app-name-staging.git (or otherwise use Git URL from previous info command)

Alternatively

$ git remote add forked https://git.heroku.com/app-named-staging.git

Heroku Remotes in Repo

heroku          (app-name)
forked          (app-name-staging)

Open Staging or Production Sites in Browser

$ heroku open --app app-name
$ heroku open --remote forked

Create local development Branch, Push to Staging Site, Create/Push to GitHub development Branch

$ git checkout -b development 
$ heroku keys:add (if needed due to publickeys error)
$ git push forked master
$ git push origin development

Staging and Production Site Examples

Staging URL

https://deployment-example-staging.herokuapp.com

Production URL

https://deployment-example.herokuapp.com

Two ways to Change URL

$ heroku apps:rename new-name --remote forked
$ heroku apps:rename new-name --app old-name

Merge Changes Between development and master Branches, Push and Pull Between GitHub and Local Branches

Merge changes from development branch into master branch

$ git checkout master
$ git merge development -m "Message" (merge local development branch changes into local master branch)

Add and commit files, with message

$ git add -A
$ git commit -m "Message" 

Push to GitHub master branch and Heroku master branch

$ git push origin master
$ git push heroku master

Merge changes from master branch into development branch

$ git checkout development
$ git merge master  -m "Message" (merge local master branch changes into local development branch)

Add and commit files, with message

$ git add -A
$ git commit -m "Message" 

Push to GitHub development branch and Heroku forked master (staging site)

$ git push origin development
$ git push forked master

To Escape Git Message, if needed

ESC
$ :wq

Pull changes (checkout as needed)

$ git pull origin master
$ git pull origin development
