Add public app


Supervisely supports both private and public apps.

🔒 Private apps are those that are available only on your private Supervisely Instance (Enterprise Edition) in your account. The guidelines for adding public apps is this tutorial.

🌎 Public apps are available on all private Supervisely Instances and in Community Edition.

This tutorial covers the case of adding a public app. It means that this app is open-sourced and is available on all Supervisely instances (Community Edition and all private customer's instances with Enterprise Edition license).

Only for Supervisely Team.

Version releases and Branch releases

There are two types of releases: version and branch. The version release is made from the main or master branch. With each version release, a release tag is added to the last commit. This tag is used to identify the release version and is important for the app versioning. If during the release process, the tag is not created, the release will be rejected. With version releases, you can specify the release version and description. The branch releases are for testing and debugging and are made from any other branch except main or master. With branch releases, you can't specify the release version and description. The release version will be the branch name.

Multi-app repositories

In Supervisely you can have a single git repository with multiple applications. It is advised to have connected applications with a common codebase in the same repository. By default supervisely release command will release the application from the root directory of the repository. If you have multiple applications in the repository, you can specify the path to the application directory with the -a flag. The application directory is a directory with a config.json file. Such applications are called subapps. For example, if you have a repository with two applications in the train and serve directories, you can release the train application with the following command:

supervisely release -a train

When making a release the tag is added to the last commit. And since all of the applications are in the same repository, it is impossible to differentiate the release tags of different applications. Therefore, it is advised to do a release for each subapp with every new version.

Step 1. Create a repository

Create an app repository on GitHub in a Supervisely-ecosystem organization. *How to create an app

Step 2. Add GitHub workflow

Add a GitHub workflow files from this repository:

  1. To publish the app to the production (see step 3): .github/workflows/publish.yml

  2. For version releases (see step 4.1): .github/workflows/release.yml

  3. For branch releases (see step 4.2): .github/workflows/release_branch.yml

Workflow files to release the app as private and as public are the same. If you already have .github/workflows/release.yml or .github/workflows/release_branch.yml you only need to add .github/workflows/publish.yml file.

name: Release
run-name: Release version "${{ github.event.release.tag_name }}"
    types: [published]
      - main
      - master
      SUBAPP_PATHS: "__ROOT_APP__, subapp" <-- Change this variable

In each of this files, you should change the following variable: SUBAPP_PATHS - Paths to directories with applications within the repository (directory where the config.json file is located). If the application is located in a root directory, then you should specify __ROOT_APP__ instead of the path. Paths should be separated by commas.

In the example above, releases are configured for two applications in the repository: the one which is located in root directory and the one which is located in the subapp directory. Example for the repository with two applications, located in train and serve directories: SUBAPP_PATHS: "train, serve".

Step 3. Publish to production

Workflow files to release the app as private and as public are the same. To make your private app public you need to run Publish to production workflow.

This workflow will create a public release for all the GitHub releases in the repository. Only releases with valid version names (in semver format) will be published.

To run the workflow you need to go to the Actions tab of the repository and select the Publish app to production workflow. Then click on the Run workflow button. Do not change the Target of the release. It should always be main or master.

After the app is published to the production you will no longer be able to create releases via CLI tool and you will need to create releases via GitHub interface. How to do it is described below in steps 3.2 and 3.3.

Step 4. Create a release

4.1 Version release

The workflow we created in the previous step will be triggered when you publish a release in the repository.

To create a release, go to the repository page on GitHub and click on the Releases tab. Then click on the Create a new release or Draft a new release button. Choose a tag version in semver format (v1.0.0) and a release title. Then click on the Publish release button.

Do not change the Target of the release. It should always be main or master.

4.2 Branch release

The workflow we created in the previous step will be triggered when you push a branch (except "main" or "master") in the repository.

You can disable branch release by adding branch name to branches-ignore list in the .github/workflows/release_branch.yml workflow file. See below

name: Release branch
run-name: Release "${{ github.ref_name }}" branch
      - main
      - master
      - branch-to-ignore <-- Add branch name here

After the release is published the workflow will be triggered and you can see the release progress in the Actions tab. If the workflow is successful, the app will appear in the ecosystem.

App development process

App Development and local tests

The developer creates the application and tests it locally.

Testing on development instance

When you done with development and local tests, you can test your app on the development instance. To do so you need to create a private app on the development instance and then create a new release. *How to add private app.

The preferred way is to use CLI tool from the SDK. From the environment where you have installed the SDK, run the following command: supervisely release and follow the instructions. Make sure you set the correct server address and API token. After the release is created, you can find the application in the Private apps tab of the ecosystem.

For development in a team you need to add APP_RELEASE_TOKEN variable to your ~/supervisely.env file. Ask the administrator for the token.

Releasing the app to the public

When you are ready to publish your app to the public, you need to create a public app. To do so you need to follow the steps described in the steps 1 to 3 of this tutorial. After the app is published to the public you will no longer be able to create releases via CLI tool.

Do not forget to add the app to the README_v2. It is needed for back-compatibility with older versions of Supervisley instances. To check that the app is released on older instances ask the administrator.

Developing new features

Still in development

You may be asking yourself: "How can I develop new features for my app if I can't create releases via CLI tool?". There is a solution for that. Future feature development and testing are done in development branches (any branch other than main or master).

To activate this mechanism you need to add another workflow file to the repository: You can use This file.

name: Supervisely release
run-name: Supervisely ${{ github.repository }} app release
      - main
      - master
      SUBAPP_PATHS: "__ROOT_APP__, subapp"

Same as in step 2 you need to change the SUBAPP_PATHS variable.

This workflow will be triggered on any push to any branch other than main or master. It will create a release with the name of the branch. For example, if you push to the dev branch, the release will be created with the version dev and the name dev branch release.

You can also limit branches on which the workflow will be triggered. To do so you need to replace branches-ignore parameter with branches parameter to the on section of the workflow. For example, if you want to trigger the workflow only on the test branch you need to add on: push: branches: - test

Updating the app

When you need to update the app, you need to create a new release. It is described in step 4 of this tutorial.
