Adding an application

An application is a collection of resources and configurations that are managed together. It represents the service which you are going to deploy. With PipeCD, all application’s manifests and its application configuration (app.pipecd.yaml) must be committed into a directory of a Git repository. That directory is called as application directory.

Each application can be handled by one and only one piped. Currently, PipeCD is supporting 5 kinds of application: Kubernetes, Terraform, CloudRun, Lambda, ECS.

Before deploying an application, it must be registered to help PipeCD knows

• where the application configuration is placed
• which piped should handle it and which platform the application should be deployed to

Through the web console, you can register a new application in one of the following ways:

• Picking from a list of unused apps suggested by Pipeds while scanning Git repositories (Recommended)
• Manually configuring application information

(If you prefer to use pipectl command-line tool, see its usage for the details.)

Picking from a list of unused apps suggested by Pipeds

You have to prepare a configuration file which contains your application configuration and store that file in the Git repository which your Piped is watching first to enable adding a new application this way.

The application configuration file name must be suffixed by .pipecd.yaml because Piped periodically checks for files with this suffix.

To define your application deployment pipeline which contains the guideline to show Piped how to deploy your application, please visit Defining app configuration.

Go to the PipeCD web console on application list page, click the +ADD button at the top left corner of the application list page and then go to the ADD FROM GIT tab.

Select the Piped and Platform Provider that you deploy to, once the Piped that’s watching your Git repository catches the new unregistered application configuration file, it will be listed up in this panel. Click ADD to complete the registration.

Manually configuring application information

This way, you can postpone the preparation for your application’s configuration after submitting all the necessary information about your app on the web console.

By clicking on +ADD button at the application list page, a popup will be revealed from the right side as below:

After filling all the required fields, click Save button to complete the application registering.

Here are the list of fields in the register form:

Note: Labels couldn’t be set via this form. If you want, try the way to register via the application configuration defined in the Git repository.

After submitting the form, one more step left is adding the application configuration file for that application into the application directory in Git repository same as we prepared in the above method.

Please refer Define your app’s configuration or pipecd/examples for the examples of being supported application kind.

Updating an application

Regardless of which method you used to register the application, the web console can only be used to disable/enable/delete the application, besides the adding operation. All updates on application information must be done via the application configuration file stored in Git as a single source of truth.

  name: new-name
  labels:
    team: new-team
