Adding a new app

In this guide, we will explain how to add a new app to the Runtipi App Store. The process is pretty simple and should take you less than 20 minutes.

Prerequisites

• The app you want to add is free and open-source (or at least source available with a permissive license for personal use)
• The app you want to add has an official and maintained docker image

Fork the repo

In order to open a pull request you need to fork the repo. Visit the official App Store repo (opens in a new tab) and start by clicking the "Fork" button in the upper right corner of the page. This will create a new repository with your name and an identical structure to the original repo.

Clone the repo locally

On your computer clone the repo you just forked.

git clone https://<your-github-username>/runtipi/runtipi-appstore

Create a new branch for your app

Navigate to the repoisitory you just cloned.

cd runtipi-appstore

Create a new branch for your app.

git checkout -b app/<app-name>

Create the app files

Each app requires at least the following files:

• A docker-compose.yml file to run your app
• A config.json file to configure your app
• A description in markdown format
• A logo in jpg format (512 x 512px)

Inside the repo open the apps folder and create a new folder for your app. The name should be the same as the app name without spaces or capital letters.

Create a new config.json file inside the newly create folder

{
  "name": "My super app",
  "available": true,
  "port": 8100,
  "exposable": true, # Wether the app can be exposed via a domain name
  "id": "my-app", # This should be the same name as the folder
  "description": "", # Long description of the app
  "tipi_version": 1, # Always 1 if you are adding a new app
  "version": "1.25.1", # The actual version of the app (not the tipi version)
  "categories": ["utilities"], # One or more categories for the app
  "short_desc": "", # Short description of the app
  "author": "", # Link or name of the author
  "source": "", # Link for git repo
  "website": "", # Link to the official website
  "form_fields": [] # Used to ask for more info to the user before installing. Will be explained further
}

Available categories : utilities, network, media, development, automation, social, utilities, photography, security, featured, books, data, music, finance, ai

Details for all the options of the config.json file:

If you want to add a new category, please open a new issue.

When choosing a port, please make sure that it is not in use already. You can check tipi.community/app-db (opens in a new tab) for an updated list. Feel free to let us know if there are any missing ones!

In the same folder, create a docker-compose.yml file with your app config.

version: '3.9'
services:
  my-app: # Should be exact same name as "id" field in config.json
    container_name: my-app # Should be exact same name as "id" field in config.json
    image: my-app:1.0.0 # Try to avoid "latest" tag. As it may break configs in the future.
    environment:
      - TZ=${TZ} # Can use any env variable. List in runtipi/templates/env-sample
    volumes:
      - ${APP_DATA_DIR}/data/config:/config # Always start the path with ${APP_DATA_DIR}. This will put all data inside app-data/my-app/data
      - ${APP_DATA_DIR}/data/projects:/projects
    ports:
      - ${APP_PORT}:8443
    restart: unless-stopped
    networks:
      - tipi_main_network

You'll also need to create a metadata folder and inside put the following files:

• description.md - Long description of the app in markdown format. (see other apps for inspiration)
• logo.jpg - Logo of the app in jpg format (512 x 512px) make sure the logo looks good in the dashboard

User defined environment variables

Sometimes an app is requiring more info to run it such as passwords or username. You can leverage the form_fields property in the config.json file to ask such information. Let's take for example Nextcloud. The image requires a username and password. We can simply add two fields in the config.json that will be presented to the user before installing.

{
  ...
  "form_fields": [
    {
        "type": "text",
        "label": "Username",
        "max": 50,
        "min": 3,
        "required": true,
        "env_variable": "NEXTCLOUD_ADMIN_USER"
    },
    {
        "type": "password",
        "label": "Password",
        "max": 50,
        "min": 3,
        "required": true,
        "env_variable": "NEXTCLOUD_ADMIN_PASSWORD"
    }
  ]
}

You can choose between different types of fields. The app will automatically validate the user input before submitting.

You can also define a min and max length of input with the corresponding properties. The env_variable property is the name of the variable you'll use in your docker-compose.yml file. Be sure to have a unique name.

So if we take the Nextcloud example again, this is how you would use the form_fields inside your compose file.

version: '3.7'
 
services:
  nextcloud:
    container_name: nextcloud
    image: nextcloud:23.0.3-apache
    restart: unless-stopped
    ports:
      - ${APP_PORT}:80
    volumes:
      - ${APP_DATA_DIR}/data/nextcloud:/var/www/html
    environment:
      - NEXTCLOUD_ADMIN_USER=${NEXTCLOUD_ADMIN_USER}
      - NEXTCLOUD_ADMIN_PASSWORD=${NEXTCLOUD_ADMIN_PASSWORD}

NEXTCLOUD_ADMIN_USER and NEXTCLOUD_ADMIN_PASSWORD are coming from the user inputs.

Regex validation

You can validate a user input against a regex:

{
  "env_variable": "version",
  "label": "Version",
  "pattern_error": "Version must be in the format x.y.z",
  "regex": "^[0-9]+.[0-9]+.[0-9]+$",
  "required": true,
  "type": "text"
}

The regex will be tested against the user input. If it doesn't match, the user will see the error message defined in pattern_error.

Multi select

You can also define a multi select field. This will be rendered as a dropdown in the UI.

{
  "label": "Select your favorite fruits",
  "type": "text",
  "required": true,
  "options": [
    { "label": "Apple", "value": "apple" },
    { "label": "Banana", "value": "banana" },
    { "label": "Orange", "value": "orange" }
  ],
  "env_variable": "fruits"
}

Default data folder

If your app requires default files or configuration, you can easily provide those by creating a data folder beside the app config.

Anything placed under data will be copied over app-data/<app-id>/data before installation. Then you can mount those files inside your compose file.

my-app:
  container_name: my-app
  restart: unless-stopped
  volumes:
    - ${APP_DATA_DIR}/data:/var/lib/config # Will mount the folder with `anything.conf` inside

Using a template in your data folder

If one of your files requires some dynamic values, you can use a template file. Let's take the example of a config.ini file that requires the APP_PORT variable.

[my-app]
port = {{APP_PORT}}

If you name your file config.ini.template, it will automatically replace the variables with the values defined in the environment variables.

For example if you put the previous example in data/config.ini.template, it will be copied over to app-data/<app-id>/data/config.ini with the APP_PORT variable replaced.

Per-architecture docker-compose files

If your app requires different docker-compose files for different architectures, you can use the following naming convention:

docker-compose.arm64.yml

If the user is running on an arm64 architecture, this file will be used instead of the default docker-compose.yml.

Commit your changes

Once you're done, you can commit your changes to the repository.

git add .
git commit -m "Add my-app"
git push origin master

Submit a Pull Request

You can now submit a pull request to the repository.

• On GitHub, visit your repository and click on the "Pull requests" tab.
• Click on "New pull request" and fill in the title and description.
• Choose your branch and target the main repository at runtipi/runtipi-appstore.

Test your app in your own instance

Before submitting your app, you can test it in your own instance. You can do so by adding your app repository to the appsRepoUrl property in the settings.json file. Visit the Using your own appstore repo section to learn more.
