Install Kirby 3 on fortrabbit

Kirby is a popular, file based CMS originated from Germany (YEAH!). Learn here how to install and tune Kirby on fortrabbit.

Get ready

Make sure you to have completed all steps in the get ready guide.

Choose your deployment work-flow

There are two "main" ways to deploy code here on fortrabbit: Git and SFTP. The general rule of thumb is, that content driven legacy applications, like WordPress, are better uploaded in classical manner with SFTP. Modern PHP web frameworks that are based on Composer are mostly deployed with Git.

Now, Kirby is a bit in between and is - like Grav - file based. So there is no database, the actual contents are text files written on the file system.

Our architecture graphic here shows you that the files, you can access via SFTP or SSH (Universal App) are not the ones, that are in Git. The Git repo is a separated thing. So, deploying with Git is a one way street that only goes up, not down. In other words: You can NOT git pull any changes you have made on the Apps file system. In an ideal world, code and content are maybe separated. With a file based CMS this is all together.

SFTP upload

There is not much to say on that topic. Just make sure to upload all contents of your local Kirby folder, including the hidden .htaccess file into the htdocs folder within your App.

Deploy with Git and Composer

Kirby 3 has Composer support, so a clean way to deploy it is possible. Make sure to read the Kirby meets Composer article from official Kirby docs. Here is a basic rundown:

  1. Initialize Kirby with Composer on your local machine
  2. Deploy to fortrabbit using Git and Composer
  3. Synchronize contents with rsync

Install Kirby locally with Composer

# 1. Create a local (on your own computer) kirby project folder with Composer:
$ composer create-project getkirby/plainkit {{app-name}}

Note that Kirby offers a "starterkit" (with some demo contents and a theme with some templates) and a "plainkit" with no contents at all (which is used here). Maybe you also have a project running locally and are just looking for ways to deploy that. Continue with the next steps.

Configure Kirby for Git deployment

Open your local Kirby project folder with your text editor or IDE. Within there open the (hidden) .gitignore file on top level to tell Git to ignore some folders. Add those two lines:

# Kirby itself

# Composer dependencies

# Stuff you are creating

PLEASE NOTE: The setting above will also keep the /content folder out of Git. This is our opinionated way to do it. It will help keeping your repo tidy and separating code from content. But you will need to run dedicated rsync commands to deploy and update the "contents" (see below). You can also decide to exclude the /content with the .gitignore so that you can deploy everything with Git all together. Keep in mind that you can not pull in new contents from the fortrabbit App this way.

At that point you should be able to run the project in your local development environment already. We highly recommend to develop the site locally, use fortrabbit for staging and production.

Deploy Kirby with Git

# 1. Initialize Git
$ git init .

# 2. Add your Apps Git remote to your local repo
$ git remote add fortrabbit {{ssh-user}}@deploy.{{region}}{{app-name}}.git

# 4. Add changes to Git
$ git add -A

# 5. Commit changes
$ git commit -m 'My first commit'

# 6. Initial push and upstream
$ git push -u fortrabbit master

# From there on only
$ git push

Synchronize your contents

As mentioned above, deployment of your code base (templates and configuration) and dependencies (Kirby and Composer) is done via Git deployment. Deploying the content is a separated step. We recommend to use rsync to up- or down-load new contents to and from your remote fortrabbit App (see also our rsync article). On your local computer in the Terminal in the kirby project folder execute:

# SYNC UP: from local to remote
$ rsync -av ./content {{app-name}}@deploy.{{region}}

It works also the other way around. For example in a case, where you have done some edits online and want those changes to be reflected in your local development environment:

# SYNC DOWN: from remote to local
$ rsync -av {{app-name}}@deploy.{{region}} ./content

You can also use SFTP to synchronize the content folder.


By now, you have Kirby installation running on your local machine and you can easily deploy it to your fortrabbit App. You can deploy code changes and Kirby updated with Git. Additionally contents are synced down and up using rsync or Git. Let's get deeper:

Working with the Panel

Kirby - like other CMS - has a "Panel". That Dashboard enables you - or maybe the client/editor - to create and edit the contents easily in the Browser. You can create different users (admins) for the Panel. When first visiting the panel, locally, you are greeted to set up the first admin user.

The panel users are by default NOT stored with Git. So your local users will not available on the fortrabbit App. You can now either include the users with Git by removing the according lines from .gitignore or - maybe better - set up the users locally and on the remote App:

Continuos development

We recommend to always develop locally first — it's just the most convenient way. Deploy, when you have reached a certain status of development. In many cases the real content will be created on the fortrabbit App. You can easily sync down changes from production into development with rsync.


Some fortrabbit App plans have backups enabled. You can also spin your own solution. With Git you can already easily rollback changes.

Updating Kirby

We recommend to update your local development environment first. On your local computer issue composer update in Terminal on root level of the project folder to trigger the update. When you have confirmed that everything works, git push to bring the latest updates to your fortrabbit App.

Sending mails

fortrabbit does not support sendmail, so sending mails out of the box might not work. Kirby provides config for transactional mail providers, or you can use a plugin to send e-mail over your own SMTP account.

Getting a license

Remember that Kirby is not a free software. Get a license, support the authors!
