Continuous Deployment Events

Continuous Deployment (CD) events are related to continuous deployment pipelines and their target environments. These events can be emitted by environments to report where software artifacts such as services, binaries, daemons, jobs or embedded software are running.

Subjects

This specification defines two subjects in this stage: environment and service. The term service is used to represent a running Artifact. A service can represent a binary that is running, a daemon, an application, a docker container. The term environment represent any platform which has all the means to run a service.

Subject Description Predicates
environment An environment where to run services created, modified, deleted
service A service deployed, upgraded, rolledback, removed, published

environment

An environment is a platform which may run a service.

Field Type Description Examples
id String See id 1234, maven123, builds/taskrun123
source URI-Reference See source staging/tekton, tekton-dev-123
type String See type environment
name String Name of the environment dev, staging, production, ci-123
url String URL to reference where the environment is located https://my-cluster.zone.my-cloud-provider

service

A service can represent for example a binary that is running, a daemon, an application or a docker container.

Field Type Description Examples
id String See id service/myapp, daemonset/myapp
source URI-Reference See source staging/tekton, tekton-dev-123
type String See type service
environment Object (environment) Reference for the environment where the service runs {"id": "1234"}, {"id": "maven123, "source": "tekton-dev-123"}
artifactId Purl Identifier of the artifact deployed with this service pkg:oci/myapp@sha256%3A0b31b1c02ff458ad9b7b81cbdf8f028bd54699fa151f221d1e8de6817db93427, pkg:golang/mygit.com/myorg/myapp@234fd47e07d1004f0aed9c
