Deploy Backend Apps

To deploy a backend application on Hostman, go to the App platform section and click Create.

Step 1. Select the Application Type

Go to the Backend tab and select the framework your application uses. 

Step 2. Connect Repository

You can connect a repository:

• From your GitHub, GitLab, or BitBucket account. Click on the platform name, log in and select the desired repository. If you are already logged in, Hostman will immediately show the available repositories.

• By URL, providing a link to a repository created on any platform. Click Connect the repository via URL and enter the Git URL of the repository. If the repository is private, also enter the access details.

Read more about connecting repositories here.

Step 3. Select Branch and Commit

1. Select a branch for deployment.
2. By default, we enable the Build by the last executed commit option. In this case, the App platform will deploy the latest commit, and later will automatically rebuild the application when you add new commits to the repository. If necessary, you can disable automatic deployment in the future.

If you want to select a specific commit manually, disable this option.

Step 4. Select Server Location and Configuration

Your application must run on a separate cloud server. Select the region where the server should be located and its configuration.

You can always upgrade your server later, however, downgrading will not be possible.

Step 5. Configure Private Network

Now, you can add the application to a private network and specify the IP address the app will use.

Note that you cannot change the private network after the deployment.

Step 6. Configure the Build Settings

At this stage you can:

• set the build command;
• set dependencies;
• set the startup command;
• set environment variables.

In most cases, the app platform will automatically determine the start command for your project, so you can leave it unchanged.

If you need additional system packages (for example, for building a project), specify them in the Dependencies section. They will be passed to the apt install command. You can enter multiple dependencies separating them with a space.

You will be able to change any of these settings later and redeploy the app with the new parameters.

Step 7. Enter the App Information

Here you can specify a name and a comment for your application to be displayed in the Hostman dashboard. You can also select a project to add the app to.

These settings can also be changed later.

Step 8. Deploy

Click Start Deploy. Once the process starts, you will see the deployment log on the Deploy tab.

The deploy log contains all the necessary information to solve possible issues. If something goes wrong, for example, due to errors in the code, the deploy log will display the notification about it specifying the cause of the problem.

When you first deploy a project, the server installation may take some time. Once the process is completed, the application status will be updated, and you will also see a message about this in the log.

All done!

You can find the application's IP address and the technical domain linked to the app in the Dashboard tab. The application will be available on port 443; port 80 is also open.

To link your own domain to the app, follow this guide.

In the future, the App platform will monitor updates in the repository and, if automatic deployment is enabled, automatically rebuild the project with new changes.
