Azure Pipelines YAML CD features now generally available

We’re excited to announce the general availability of the Azure Pipelines YAML CD features. We now offer a unified YAML experience to configure each of your pipelines to do CI, CD, or CI and CD together.

Releases vs. YAML pipelines

Azure Pipelines supports continuous integration (CI) and continuous delivery (CD) to test, build and ship your code to any target – repeatedly and consistently. You accomplish this by defining a pipeline. CD pipelines can be authored using the YAML syntax or through the visual user interface (Releases).

Classic vs YAML pipelines

You can create and configure release pipelines in the web portal with the visual user interface editor (Releases). A release pipeline can consume and deploy the artifacts produced by the CI pipelines to your deployment targets. On the other hand, you can define the CI/CD workflows in a YAML file – azure-pipelines.yml. The pipelines file is versioned with your code. It follows the same branching structure. As result, you get validation of the changes through code reviews in pull requests and branch build policies. Most importantly, the changes are in the version control with the rest of the codebase so you can easily identify the issue.

Highlights

YAML CD features introduces several new features that are available for all organizations using multi-stage YAML pipelines. Some of the highlights include.

Multi-stage YAML pipelines (for CI and CD)

Stages are the major divisions in a pipeline: “build app”, “Run tests”, and “deploy to Prod” are good examples of stages. They are a logical boundary in your pipeline at which you can pause the pipeline and perform various checks. Stages may be arranged into a dependency graph. For example, “run dev stage before the QA”.

Resources in YAML pipelines

A resource defines the type of artifact used by a pipeline. Resources provide full traceability of the artifacts consumed in your pipeline. It includes artifact, version, associated commits, and work-items. Most importantly, fully automate the DevOps workflow by subscribing to trigger events on your resources. Supported type of resources are: pipelines, builds, repositories, containers, and packages.

resources:
  pipelines: [ pipeline ]  
  builds: [ build ]
  repositories: [ repository ]
  containers: [ container ]
  packages: [ package ]

Environments and deployment strategies

An environment is a collection of resources that can be targeted for deployment from a pipeline. Environments can include Kubernetes clusters, Azure web apps, virtual machines, databases etc. Typical examples of environment names are Dev, Test, QA, Staging, and Production.

Kubernetes and Virtual Machine resources in environment

Kubernetes resource view provides the status of objects within the mapped Kubernetes namespace. It overlays pipeline traceability on top so you can trace back from the Kubernetes object to the pipeline and to the commit. Virtual machine resource view lets you add your VMs that are on any cloud or on-premises. As a result, rollout application updates and track deployments to the virtual machines.

Approvals and checks on resources

Pipelines rely on resources such as environments, service connections, agent pools, and library items. Checks enable the resource owner to control whether a stage in a pipeline can consume the resource. As an owner, you can define the checks that must be met prior a stage consuming that resource can start. For example, a manual approval checks on an environment ensures that deployment can happen only after the reviewers have signed-off.

Review apps for collaboration

Review apps works by deploying every pull request from your git repository to a dynamically created resource in an environment. The team can see the changes in the PR, as well as how they work with other dependent services before they’re merged into the main branch. As a result, you to shift-left the code quality and improve productivity.

Refreshed UX for service connections

We have improved the service connection user experience. Further, enabled configuring approvals and checks on service connections. For approvals, we follow segregation of roles between the resource owners and developers. For instance, any pipeline runs that use a connection with the checks enabled will pause the workflow.
