Settings

On your application’s Settings page, you can find details about your application, manage settings like buildpacks, and suspend or delete it.

General

Details

This section shows the application display name, name, and ID. To change the display name, click Update display name, enter a new name, and click Update.

Application display name, name, and ID.

Source

This shows the information about the application source. The information shown depends on whether you use a Git repository or a Docker image.

Git repository

• Source type: Shows if the repository is private or public.
• Git type: Shows which Git provider the application is using.
• Repository and Default branch: The Git repository and branch.
• Automatic deployment on commit: When this box is checked, your application will automatically deploy each time a commit is made to the branch selected above.

The source information for an application hosted on GitHub.

To change any of the details, click Update source. If you change the Branch, you must manually deploy your application again, which you can do on the Deployments page.

Docker image

• Source type: This shows that the application is using a Docker image.
• Docker image: This is the path to your Docker image.
• Registry credential: This shows the name of the registry credentials set up within Company settings > Registry credentials.

The source information for an application using a Docker image.

To change any of the details, click Update source. If you change the Registry credential, you must manually deploy your application again, which you can do on the Deployments page.

Deploy hook

Deploy hooks allow you to effortlessly trigger deployments by making a simple POST request to a unique URL, enabling seamless workflow integration.

To set up a deploy hook, click Enable; this generates a unique URL that you can call with a POST request to trigger a deployment. If you want to automate deployments based on external events (e.g., pushing code to a repository), you can configure a webhook in your repository provider (GitHub, GitLab, Bitbucket, or Docker) to call the deploy hook URL.

Set up a deploy hook for your application.

Deploy paths

Deploy paths allow you to trigger deployments based on a specific set of rules. You can define which file changes should initiate a deployment and which should be ignored. For example, you can trigger deployments only when files in /src/backend/** are modified or skip deployments if changes are limited to **/*.md files. This can be especially useful for monorepos.

[notice type="important"]This feature is only available for applications with a private GitHub or GitLab repository. It is not available for Bitbucket repositories or Docker images.[/notice]

To configure deploy paths, click Edit settings.

Configure deploy paths.

To trigger a deployment when a file is changed within a specific path, select Allow paths. To skip a deployment when a file is changed in a specific path, select Ignore paths. Add the required path patterns and click Edit settings.

Add the required deploy paths to trigger or skip a deployment.

Hibernation

Hibernation automatically scales down your application if no HTTP requests are received within the specified timeframe. When traffic resumes, the application wakes up in 30-90 seconds, with the HTTP request remaining pending during that time. Cron jobs and other jobs continue to run normally, even while hibernation is active. To enable hibernation on your application, click Edit hibernation.

Hibernate your application when idle.

Select Hibernate App, enter the number of idle minutes after which you want your application to enter hibernation, and click Save changes.

Hibernation settings for your application.

Build

info

This is only applicable to applications using a Git repository.

Build resources

This shows the build machine used to build your application.

The applications resources within Settings.

Build environment

This shows which environment type is used to build your application and the build path.

The applications environment within Settings.

To change the build environment, click Change environment, and select from one of the following:

Nixpacks

Use Nixpacks to create a container for your application based on your repository.

• Build path: This is the path in the repository to the files required to build the application. Most applications are built from the repository root, and the Build path defaults to this (.). If you have a different build path, specify it here. For example, if your application needs to be built from a subdirectory named app, enter app in the Build path field. This is also useful if you have a monorepo.

Select Nixpacks for your build environment.

Buildpacks

Use Buildpacks to create a container for your application based on your repository.

• Build path: This is the path in the repository to the files required to build the application. Most applications are built from the repository root, and the Build path defaults to this (.). If you have a different build path, specify it here. For example, if your application needs to be built from a subdirectory named app, enter app in the Build path field. This is also useful if you have a monorepo.
• Pack builder: Choose which buildpack builder you want to use. For information about what each builder includes, refer to Heroku stacks.
• Add buildpack: Add the required buildpacks for your application. The buildpack that contains the primary language of your application must be the last one in the buildpacks list. For example, if you have a Node.js application and need to add another buildpack, make sure the Node.js build pack is at the end of the list.

Select Buildpacks for your build environment.

Dockerfile

Use a Dockerfile (stored in your repository) to create a container for your application.

• Dockerfile path: This is the path to your Dockerfile relative to the repository root. For example, if your Dockerfile is in the repository root, enter Dockerfile in that field. If your Dockerfile is in a subdirectory named app, enter the path to the Dockerfile: app/Dockerfile.
• Context: This is the path in the repository we need access to so we can build your application. Most applications are built from the repository root, and you can enter the repository root (.) in the Context field. For example, if your application needs to be built from a subdirectory named app, enter app in the Context field.
• Registry credential: This is only required for private Docker images. You must enter your registry credentials within username > Company settings > Registry credentials. Once you’ve entered your credentials in the Company settings, you can choose which credentials you want to use.

Select Dockerfile for your build environment.

If you change the environment, you must manually deploy your application again, which you can do on the Deployments page.

Danger zone

info

Only Company Owners and Company Administrators can suspend, resume, or delete an Application. For information about how to change a user’s access, refer to User Management.

Suspend or resume application

There may be times when you need to stop an application without deleting it. This can be useful if you need to troubleshoot issues or test parts of the application without it running.

Suspending the application doesn’t change or remove anything from it. Connections to the application remain in place but will not work while the application is suspended. You will not incur any costs for the application during the suspension.

Click Suspend application and confirm the suspension by clicking Suspend application again in the modal/pop-up.

Suspend an application in Sevalla.

When you’re ready to restart your application, click Resume application and confirm the restart by clicking Resume application again in the modal/pop-up.

Resume an application in Sevalla.

Delete application

If you no longer need the application, click Delete application, enter your application name, and click Delete application again to remove it completely.

Delete your application within the application Settings.

Deleting the application completely removes the following:

• All files
• Settings
• Persistent storage disks
• Connections to other applications or databases.
