This project is a template for installing and running WordPress on Heroku. The repository comes bundled with:

heroku config:set AUTH_KEY='put your unique phrase here' \
  SECURE_AUTH_KEY='put your unique phrase here' \
  LOGGED_IN_KEY='put your unique phrase here' \
  NONCE_KEY='put your unique phrase here' \
  AUTH_SALT='put your unique phrase here' \
  SECURE_AUTH_SALT='put your unique phrase here' \
  LOGGED_IN_SALT='put your unique phrase here' \
  NONCE_SALT='put your unique phrase here'

       http://strange-turtle-1234.herokuapp.com deployed to Heroku

To git@heroku:strange-turtle-1234.git
  * [new branch]    production -> master

After deployment WordPress has a few more steps to setup and thats it!

Usage

Because a file cannot be written to Heroku's file system, updating and installing plugins or themes should be done locally and then pushed to Heroku.

Updating

Updating your WordPress version is just a matter of merging the updates into the branch created from the installation.

$ git pull # Get the latest

Using the same branch name from our installation:

$ git checkout production
$ git merge master # Merge latest
$ git push heroku production:master

WordPress needs to update the database. After push, navigate to:

http://your-app-url.herokuapp.com/wp-admin

WordPress will prompt for updating the database. After that you'll be good to go.

Deployment optimisation

If you have files that you want tracked in your repo, but do not need deploying (for example, *.md, *.pdf, *.zip). Then add path or linux file match to the .slugignore file & these will not be deployed.

Examples:

path/to/ignore/
bin/
*.md
*.pdf
*.zip
