Go to https://cloud.digitalocean.com/apps and click Create App.
Select the source for your app. You can choose a GitHub repository, a GitLab repository, or a container image you uploaded to DigitalOcean Container Registry or Docker Hub.
Select the repository that contains your source code and specify the branch or tag in your repository that contains your app’s source code. If you’d like to automatically re-deploy your app when pushing to this branch/tag, select Autodeploy code changes and click Next.
App Platform inspects the code and selects an appropriate runtime environment (such as Node, Ruby, etc). If you need to override this, upload a Dockerfile to your branch and restart the app creation process.
Configure your app.
Enter a name for your app and choose the region where you’d like your app to be hosted. Click Next.
