👋 Introduction

Setup with github codespaces

If you have github codespaces enabled then you can just create a codespace and run pnpm dev to run your the dev environment. All the required dependencies and packages has been configured for you already.

Setup locally in your machine

🔴 At the moment, Coolify doesn't support Windows. You must use Linux or MacOS. 💡 Although windows users can use github codespaces for development

Recommended Pull Request Guideline

• Fork the project
• Clone your fork repo to local
• Create a new branch
• Push to your fork repo
• Create a pull request: https://github.com/coollabsio/compare
• Write a proper description
• Open the pull request to review against next branch

How to start after you set up your local fork?

Due to the lock file, this repository is best with pnpm. I recommend you try and use pnpm because it is cool and efficient!

You need to have Docker Engine installed locally.

Steps for local setup

1. Copy .env.template to .env and set the COOLIFY_APP_ID environment variable to something cool.

2. Install dependencies with pnpm install.

3. Need to create a local SQlite database with pnpm db:push.

   This will apply all migrations at db/dev.db.

4. Seed the database with base entities with pnpm db:seed

5. You can start coding after starting pnpm dev.

🧑‍💻 Developer contribution

Technical skills required

• Languages: Node.js / Javascript / Typescript
• Framework JS/TS: Svelte / SvelteKit
• Database ORM: Prisma.io
• Docker Engine

Database migrations

During development, if you change the database layout, you need to run pnpm db:push to migrate the database and create types for Prisma. You also need to restart the development process.

If the schema is finalized, you need to create a migration file with pnpm db:migrate <nameOfMigration> where nameOfMigration is given by you. Make it sense. :)

Tricky parts

• BullMQ, the queue system Coolify uses, cannot be hot reloaded. So if you change anything in the files related to it, you need to restart the development process. I'm actively looking for a different queue/scheduler library. I'm open to discussion!

How to add new services

You can add any open-source and self-hostable software (service/application) to Coolify if the following statements are true:

• Self-hostable (obviously)
• Open-source
• Maintained (I do not want to add software full of bugs)

Backend

There are 5 steps you should make on the backend side.

1. Create Prisma / database schema for the new service.
2. Add supported versions of the service.
3. Update global functions.
4. Create API endpoints.
5. Define automatically generated variables.

I will use Umami as an example service.

Create Prisma / database schema for the new service.

You only need to do this if you store passwords or any persistent configuration. Mostly it is required by all services, but there are some exceptions, like NocoDB.

Update Prisma schema in prisma/schema.prisma.

• Add new model with the new service name.
• Make a relationshup with Service model.
• In the Service model, the name of the new field should be with low-capital.
• If the service needs a database, define a publicPort field to be able to make it's database public, example field name in case of PostgreSQL: postgresqlPublicPort. It should be a optional field.

If you are finished with the Prisma schema, you should update the database schema with pnpm db:push command.

You must restart the running development environment to be able to use the new model

If you use VSCode, you probably need to restart the Typescript Language Server to get the new types loaded in the running VSCode.

Add supported versions

Supported versions are hardcoded into Coolify (for now).

You need to update supportedServiceTypesAndVersions function at src/lib/components/common.ts. Example JSON:

     {
       // Name used to identify the service internally
       name: 'umami',
       // Fancier name to show to the user
       fancyName: 'Umami',
       // Docker base image for the service
       baseImage: 'ghcr.io/mikecao/umami',
       // Optional: If there is any dependent image, you should list it here
       images: [],
       // Usable tags
       versions: ['postgresql-latest'],
       // Which tag is the recommended
       recommendedVersion: 'postgresql-latest',
       // Application's default port, Umami listens on 3000
       ports: {
         main: 3000
       }
     }

Update global functions

1. Add the new service to the include variable in src/lib/database/services.ts, so it will be included in all places in the database queries where it is required.

const include: Prisma.ServiceInclude = {
	destinationDocker: true,
	persistentStorage: true,
	serviceSecret: true,
	minio: true,
	plausibleAnalytics: true,
	vscodeserver: true,
	wordpress: true,
	ghost: true,
	meiliSearch: true,
	umami: true // This line!
};

2. Update the database update query with the new service type to configureServiceType function in src/lib/database/services.ts. This function defines the automatically generated variables (passwords, users, etc.) and it's encryption process (if applicable).

[...]
else if (type === 'umami') {
		const postgresqlUser = cuid();
		const postgresqlPassword = encrypt(generatePassword());
		const postgresqlDatabase = 'umami';
		const hashSalt = encrypt(generatePassword(64));
		await prisma.service.update({
			where: { id },
			data: {
				type,
				umami: {
					create: {
						postgresqlDatabase,
						postgresqlPassword,
						postgresqlUser,
						hashSalt,
					}
				}
			}
		});
	}

3. Add decryption process for configurations and passwords to getService function in src/lib/database/services.ts

if (body.umami?.postgresqlPassword)
	body.umami.postgresqlPassword = decrypt(body.umami.postgresqlPassword);

if (body.umami?.hashSalt) body.umami.hashSalt = decrypt(body.umami.hashSalt);

4. Add service deletion query to removeService function in src/lib/database/services.ts

Create API endpoints.

You need to add a new folder under src/routes/services/[id] with the low-capital name of the service. You need 3 default files in that folder.

index.json.ts:

It has a POST endpoint that updates the service details in Coolify's database, such as name, url, other configurations, like passwords. It should look something like this:

import { getUserDetails } from '$lib/common';
import * as db from '$lib/database';
import { ErrorHandler } from '$lib/database';
import type { RequestHandler } from '@sveltejs/kit';

export const post: RequestHandler = async (event) => {
	const { status, body } = await getUserDetails(event);
	if (status === 401) return { status, body };

	const { id } = event.params;

	let { name, fqdn } = await event.request.json();
	if (fqdn) fqdn = fqdn.toLowerCase();

	try {
		await db.updateService({ id, fqdn, name });
		return { status: 201 };
	} catch (error) {
		return ErrorHandler(error);
	}
};

If it's necessary, you can create your own database update function, specifically for the new service.

start.json.ts

It has a POST endpoint that sets all the required secrets, persistent volumes, docker-compose.yaml file and sends a request to the specified docker engine.

You could also define an HTTP or TCP proxy for every other port that should be proxied to your server. (See startHttpProxy and startTcpProxy functions in src/lib/haproxy/index.ts)

stop.json.ts

It has a POST endpoint that stops the service and all dependent (TCP/HTTP proxies) containers. If publicPort is specified it also needs to cleanup it from the database.

Frontend

1. You need to add a custom logo at src/lib/components/svg/services/ as a svelte component.

   SVG is recommended, but you can use PNG as well. It should have the isAbsolute variable with the suitable CSS classes, primarily for sizing and positioning.

2. You need to include it the logo at

• src/routes/services/index.svelte with isAbsolute in two places,
• src/lib/components/ServiceLinks.svelte with isAbsolute and a link to the docs/main site of the service
• src/routes/services/[id]/configuration/type.svelte with isAbsolute.

3. By default the URL and the name frontend forms are included in src/routes/services/[id]/_Services/_Services.svelte.

   If you need to show more details on the frontend, such as users/passwords, you need to add Svelte component to src/routes/services/[id]/_Services with an underscore. For example, see other files in that folder.

   You also need to add the new inputs to the index.json.ts file of the specific service, like for MinIO here: src/routes/services/[id]/minio/index.json.ts

🌐 Translate the project

The project use sveltekit-i18n to translate the project. It follows the ISO 639-1 to name languages.

Installation

You must have gone throw all the intro steps before you can start translating.

It's only an advice, but I recommend you to use:

• Visual Studio Code
• i18n Ally for Visual Studio Code: ideal to see the progress of the translation.
• Svelte for VS Code: to get the syntax color for the project

Adding a language

If your language doesn't appear in the locales folder list, follow the step below:

1. In src/lib/locales/, Copy paste en.json and rename it with your language (eg: cz.json).
2. In the lang.json file, add a line after the first bracket ({) with "ISO of your language": "Language", (eg: "cz": "Czech",).
3. Have fun translating!
