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 cloud 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

In this way, you define all information in the application configuration defined in the Git repository and use it as a single source of truth.

It starts with creating an application configuration file as following and pushing it to the Git repository watched by a Piped with version v0.23.0 or higher. The file name must be suffixed by .pipecd.yaml because Piped periodically checks for files with this suffix.

apiVersion: pipecd.dev/v1beta1
kind: KubernetesApp
spec:
  name: foo
  labels:
    team: bar

After waiting for a while (it depends on the Piped’s setting), 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 Cloud Provider that you deploy to, and the application you have just selected should appear as a candidate. Click ADD to complete the registration.

Manually configuring application information

In this way, you set the necessary information on the web. 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 registering the application, one more step left is adding the application configuration file for that application into the application directory in Git repository. That application configuration file helps piped know how the application should be deployed, such as doing canary/blue-green strategy or requiring a manual approval… It is in YAML format as below:

apiVersion: pipecd.dev/v1beta1
kind: ApplicationKind
spec:
  ...

• kind is the application kind and must be one of KubernetesApp, TerraformApp, CloudRunApp, LambdaApp, ECSApp
• spec is the specific configuration for each application kind

Please refer pipecd/examples for the deployments being supported.

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.

apiVersion: pipecd.dev/v1beta1
kind: KubernetesApp
spec:
  name: new-name
  labels:
    team: new-team

Refer to configuration reference to see the full list of configurable fields.
