Publish your SubQuery project to IPFS

When deploying to SubQuery's Managed Service, you must first host your codebase in IPFS. Hosting a project in IPFS makes it available for everyone and reduces your reliance on centralised services like GitHub.

GitHub Deployment flows have being deprecated for IPFS

If your project is still being deployed via GitHub, read the migration guide for IPFS deployments here :::

Требования

• @subql/cli версии 0.21.0 или выше.
• Manifest specVersion 1.0.0 and above.
• Get your SUBQL_ACCESS_TOKEN ready.
• To make sure your deployment is successful, we strongly recommend that you build your project with the subql build command, and test it locally before publishing.

Подготовьте свой SUBQL_ACCESS_TOKEN

• Шаг 1. Перейдите в раздел SubQuery Managed Service и войдите в систему.
• Step 2: Click on your profile at the top right of the navigation menu, then click on Refresh Token.
• Шаг 3: Скопируйте сгенерированный токен.
• Шаг 4: Чтобы использовать этот токен:
  • Вариант 1: Добавьте SUBQL_ACCESS_TOKEN в переменные среды. EXPORT SUBQL_ACCESS_TOKEN=<token> (Windows) or export SUBQL_ACCESS_TOKEN=<token> (Mac/Linux)
  • Вариант 2: (последует в скором времени) subql/cli будет поддерживать локальное хранение вашего SUBQL_ACCESS_TOKEN.

Как опубликовать проект

Run the following command, which will read the project's default manifest project.yaml for the required information.

// Публикуем из корневого каталога вашего проекта
subql publish

// ИЛИ указываем корневую директорию вашего проекта
subql publish -f ~/my-project/

Alternatively, if your project has multiple manifest files, for example you support multiple networks but share the same mapping and business logic, and have a project structure as follows:

L projectRoot
 L src/
 L package.json
 L polkadot.yaml (Manifest для Polkadot network)
 L kusama.yaml   (Manifest для Kusama network)
 ...

Вы всегда можете опубликовать проект с выбранным файлом манифеста.

 #Это опубликует проект с поддержкой индексации сети Polkadot
subql publish -f ~/my-projectRoot/polkadot.yaml

После публикации

After successfully publishing the project, the logs below indicate that the project was created on the IPFS cluster and have returned its CID (Content IDentifier). Please note down this CID.

Building and packing code... done
Uploading SupQuery project to IPFS
SubQuery Project uploaded to IPFS: QmZ3q7YZSmhwBiot4PQCK3c7Z6HkteswN2Py58gkkZ8kNd  //CID

Note: With @subql/cli version 1.3.0 or above, when using subql publish, a copy of the project's IPFS CID will be stored in a file in your project directory. The naming of the file will be consistent with your project.yaml. For example, if your manfiest file is named project.yaml, the IPFS file will be named .project-cid.

IPFS Deployment

Развертывание в IPFS представляет собой независимое и уникальное существование проекта SubQuery в децентрализованной сети. Поэтому любые изменения с кодом в проекте повлияют на его уникальность. Если вам нужно перестроить свою бизнес-логику, например, изменить функцию сопоставления, вы должны повторно опубликовать проект, и CID изменится.

For now, to view the project you have published, use a REST api tool such as Postman, and use the POST method with the following example URL to retrieve it:https://ipfs.subquery.network/ipfs/api/v0/cat?arg=<YOUR_PROJECT_CID>.

You should see the example project deployment as below.

Это развертывание очень похоже на ваш файл манифеста. Вы можете ожидать эти описательные поля, а конечная точка сети и словаря была удалена, поскольку они не влияли напрямую на результат выполнения проекта.

Те файлы, которые использовались в вашем локальном проекте, также были упакованы и опубликованы в IPFS.

Deploy your SubQuery project in the Managed Service

Login to SubQuery Projects

Before starting, please make sure that your SubQuery project codebase is published to IPFS.

To create your first project, head to SubQuery Managed Service. You'll need to authenticate with your GitHub account to login.

On first login, you will be asked to authorize SubQuery. We only need your email address to identify your account, and we don't use any other data from your GitHub account for any other reasons. In this step, you can also request or grant access to your GitHub Organization account so you can post SubQuery projects under your GitHub Organization instead of your personal account.

SubQuery Projects is where you manage all your hosted projects uploaded to the SubQuery platform. You can create, delete, and even upgrade projects all from this application.

If you have a GitHub Organization accounts connected, you can use the switcher on the header to change between your personal account and your GitHub Organization account. Projects created in a GitHub Organization account are shared between members in that GitHub Organization. To connect your GitHub Organization account, you can follow the steps here.

Create Your First Project

There are two methods to create a project in the SubQuery Managed Service: you can use the UI or directly via the subql cli tool

Использование пользовательского интерфейса

Start by clicking on "Create Project". You'll be taken to the new project form. Please enter the following (you can change this in the future):

• Project Name: Name your project.
• Description: Provide a description of your project.
• Database: Premium customers can access dedicated databases to host production SubQuery projects from. If this interests you, you can contact sales@subquery.network to have this setting enabled.
• Visible in Explorer: If selected, this will show the project from the public SubQuery explorer to share with the community.

Create your project and you'll see it on your SubQuery Project's list. Next, we just need to deploy a new version of it.

Использование CLI

You can also use @subql/cli to publish your project to our Managed Service. Для этого необходимо:

• @subql/cli версии 1.1.0 или выше.
• Действительный SUBQL_ACCESS_TOKEN готов.

// Creating a project using the CLI
$ subql project:create-project

// OR using non-interactive, it will prompt you if the required fields are missing
$ subql project:create-project
    --apiVersion=apiVersion      Api version is default to 2
    --description=description    Enter description
    --gitRepo=gitRepo            Enter git repository
    --org=org                    Enter organization name
    --projectName=projectName    Enter project name

Deploy your First Version

There are three methods to deploy a new version of your project to the SubQuery Managed Service, you can use the UI or directly, via the subql cli tool, or using an automated GitHub Action.

Использование пользовательского интерфейса

While creating a project will setup the display behaviour of the project, you must deploy a version of it before it becomes operational. Deploying a version triggers a new SubQuery indexing operation to start, and sets up the required query service to start accepting GraphQL requests. You can also deploy new versions to existing projects here.

With your new project, you'll see a "Deploy your first version" button. Click this, and fill in the required information about the deployment:

• CID: Provide your IPFS deployment CID (without the leading ipfs://). This can be acquired by running subql publish with the CLI. The rest of the fields should then auto-populate.
• Manifest: The details are obtained from the contents of the provided CID.
• Override Network and Dictionary Endpoints: You can override the endpoints in your project manifest here.
• Indexer Version: This is the version of SubQuery's node service that you want to run this SubQuery on. See @subql/node.
• Query Version: This is the version of SubQuery's query service that you want to run this SubQuery on. See @subql/query.
• Advanced Settings: There are numerous advanced settings which are explained via the inbuild help feature.

If deployed successfully, you'll see the indexer start working and report back progress on indexing the current chain. This process may take time until it reaches 100%.

Использование CLI

You can also use @subql/cli to create a new deployment of your project to our Managed Service. Для этого необходимо:

• @subql/cli версии 1.1.0 или выше.
• Действительный SUBQL_ACCESS_TOKEN готов.

// Deploy using the CLI
$ subql deployment:deploy

// OR Deploy using non-interactive CLI
$ subql deployment:deploy

  -d, --useDefaults                Use default values for indexerVerion, queryVersion, dictionary, endpoint
  --dict=dict                      Enter dictionary
  --endpoint=endpoint              Enter endpoint
  --indexerVersion=indexerVersion  Enter indexer-version
  --ipfsCID=ipfsCID                Enter IPFS CID
  --org=org                        Enter organization name
  --projectName=projectName        Enter project name
  --queryVersion=queryVersion      Enter query-version
  --type=(stage|primary)           [default: primary]

Using GitHub actions

With the introduction of the deployment feature for the CLI, we've added a Default Action Workflow to the starter project in GitHub that will allow you to publish and deploy your changes automatically:

• Step 1: After pushing your project to GitHub, create DEPLOYMENT environment on GitHub, and add the secret SUBQL_ACCESS_TOKEN to it.
• Step 2: Create a project on SubQuery Managed Service, this can be done using the the UI or CLI.
• Step 3: Once your project is created, navigate to the GitHub Actions page for your project, and select the workflow CLI deploy
• Step 4: You'll see an input field where you can enter the unique code of your project created on SubQuery Projects, you can get the code from the URL in SubQuery's Managed Service SubQuery Managed Service. The code is based on the name of your project, where spaces are replaced with hyphens -. e.g. my project name becomes my-project-name
• Once the workflow is complete, you should be see your project deployed to our Managed Service

A common approach is to extend the default GitHub Action to automatically deploy changes to our Managed Service when code is merged into main. The following change to the GitHub Action workflow do this:

on:
  push:
    branches:
      - main
jobs:
  deploy:
    name: CLI Deploy
    ...

Следующие шаги - подключитесь к вашему проекту

После успешного завершения установки и успешного индексирования нашими узлами ваших данных из цепочки, вы сможете подключиться к вашему проекту через отображённую конечную точку запроса GraphQL Query.

Кроме того, вы можете щелкнуть три точки рядом с названием вашего проекта и просмотреть его в SubQuery Explorer. There you can use the in-browser playground to get started - read more about how to use our Explorer here.

Add GitHub Organization Account to SubQuery Projects

It is common to publish your SubQuery project under the name of your GitHub Organization account rather than your personal GitHub account. At any point your can change your currently selected account on SubQuery Managed Service using the account switcher.

If you can't see your GitHub Organization account listed in the switcher, the you may need to grant access to SubQuery for your GitHub Organization (or request it from an administrator). To do this, you first need to revoke permissions from your GitHub account to the SubQuery Application. Then, login to your account settings in GitHub, go to Applications, and under the Authorized OAuth Apps tab, revoke SubQuery - you can follow the exact steps here. Don't worry, this will not delete your SubQuery project and you will not lose any data.

Once you have revoked access, log out of SubQuery Managed Service and log back in again. You should be redirected to a page titled Authorize SubQuery where you can request or grant SubQuery access to your GitHub Organization account. If you don't have admin permissions, you must make a request for an adminstrator to enable this for you.

Once this request has been approved by your administrator (or if are able to grant it youself), you will see the correct GitHub Organization account in the account switcher.
