Upgrade to service and environment v2

info

This is an End of Life (EOL) notice for the CD NextGen service and environment v1 experience.

To provide the best software delivery experience for our customers, Harness has introduced an enhanced experience for service and environment entities in the CD NextGen platform. We have named this enhanced experience service and environment v2.

The v2 experience goes into effect as the default experience on Jan 31, 2023.

Except for specific Harness accounts, the current v1 experience will be removed from all accounts on that date.

Why make the change?​

The v2 experience has more robust service and environment entities. V2 has service variables, independent infrastructure definitions, environment groups, and file and variable overrides.

With v2, you'll notice a major reduction in the configuration included in pipelines. These changes are also reflected in the Harness APIs.

All new deployment types (ECS, Deployment Template, SSH, WinRM, etc.) are available in v2 only. New innovations such as Enterprise GitOps, multi-services and multi-environments, and environment groups, are in v2 only.

The new v2 experience has been designed to provided users and organizations with simpler configurations and an improved ability to scale.

Customer impact​

Here's a summary of the impact to Harness accounts:

  • The changes only impact your CD module. No other modules are impacted.
  • No impact on any existing pipelines using v1 services and environments.
  • Post 1/31/2023, when you create a new CD stage in an existing pipeline, the v2 experience will be the default.
note

Please note that any new services and environments created in Harness after 1/31/2023 will use the new v2 experience.

Important dates​

Please review these important dates before upgrading.

  • Service and environment v1 APIs are being deprecated in March 2023.
  • On the official EOL date (Jan 31, 2023), v1 services and environments will continue to work as before. After March 2023, pipelines with v1 services and environments might experience issues or even failures because Harness will not update v1 with fixes or enhancements after that date.
  • Harness will globally enable service and environments v2 APIs for all customers at the end of January 2023.
  • The forced change will reduce the migration effort needed for users.
  • Harness has an automated tool to help migrate your services and environments from v1 to v2.

We are happy to assist you in your migration to the new v2 experience. For any questions or comments, please contact support@harness.io or your CSM. Together we can work through discovery, migration planning, and assist with the process.

API changes​

Harness has introduced the following new APIs to support the v2 experience:

For steps on using these APIs, go to Migrating from v1 services and environments to v2.

Terraform provider automation​

Customers using the Harness Terraform provider will need to update their service and environment automation to use the v2 plugin resources:

Examples are provided in Changelog since service and environment v1 release below.

Changelog since service and environment v1 release​

This section contains all the v1 to v2 changes for each of the impacted entity types.

Services​

The following changes apply to services:

  • To use the service in a pipeline, service definitions must be configured via API/UI/YAML.
  • The service definition is a configuration mapped to the service irrespective of the pipelines where it is used.
  • For details on service v2, go to Services and environments overview.
  • The service entity is now moved from the pipeline to a standalone entity. The service contains the following components:
    • Name, Description, Tag, Id. These are the same as in the service v1 experience.
    • Manifests and artifacts. The service manifests and artifacts are now mapped in the service. They are moved out of the pipeline Service tab.
    • Service variables. Service variables are now associated with the Service and can be overridden at the environment level.

Service YAML updates​

Here is a a YAML sample that demonstrates the changes in v2.

service:
  name: nginx-canary
  identifier: nginxcanary
  
## SERVICE v2 UPDATE
## In v2, a service definition needs to be provided with the service in order for it to be used in a pipeline 

  serviceDefinition:
    type: Kubernetes
    spec:
    
## SERVICE v2 UPDATE  
## You will need to provide a path to your service manifests (i.e. kubernetes manifests)

      manifests:
        - manifest:
            identifier: nginx
            type: K8sManifest
            spec:
              store:

              skipResourceVersioning: false
              
## SERVICE v2 UPDATE
## You will need to add an artifact if you want to pass an image tag in at pipeline runtime 
## this is also associated with the service configuration

      artifacts:

              type: DockerRegistry
            
 ## SERVICE v2 UPDATE
 ## NEW CAPABILITY: We now have service variables that are mapped and managed with the service no longer defined in the pipeline
 ## This can be overwritten when deploying the service to different environments

REST API updates​

When creating a service via the Harness REST API, there is a new service endpoint.

Sample payload request​

{
  "identifier": "string",
  "orgIdentifier": "string",
  "projectIdentifier": "string",
  "name": "string",
  "description": "string",
  "tags": {
    "property1": "string",
    "property2": "string"
  },
  
// NEW PART OF THE SERVICE API PAYLOAD
// The YAML is optional when using the API for service creation
// The YAML is mandatory if the service will be used in a pipeline
// YAML is the service definition YAML passed as a string

  "yaml": "string" 
}

Sample payload response​

{
  "status": "SUCCESS",
  "data": {
    "service": {
      "accountId": "string",
      "identifier": "string",
      "orgIdentifier": "string",
      "projectIdentifier": "string",
      "name": "string",
      "description": "string",
      "deleted": true,
      "tags": {
        "property1": "string",
        "property2": "string"
      },
      "yaml": "string"
    },
    "createdAt": 0,
    "lastModifiedAt": 0
  },
  "metaData": {},
  "correlationId": "string"
}

Terraform provider​

Please review the changes to the Harness Terraform provider service resource.

  • The Harness Terraform Provider service resource endpoint has not changed.
  • The service resource payload has a new field added for service creation: yaml.
  • yaml is not mandatory for service object creation.
  • When creating a service without yaml defined, the Terraform provider will create a skeleton service that cannot be used for immediate deployment.
  • The yaml field defines the actual definition of the service so it can be used in a pipeline for deployment.
resource "harness_platform_service" "example" {
  identifier  = "identifier"
  name        = "name"
  description = "test"
  org_id      = "org_id"
  project_id  = "project_id"
  
## SERVICE v2 UPDATE
## We now take in a YAML that can define the service definition for a given service
## It is not mandatory for service creation 
## It is mandatory for service use in a pipeline

  yaml        = <<-EOT
                service:

                  gitOpsEnabled: false
              EOT
}

Environments​

The following changes apply to v2 environments:

  • Environments are now standalone objects with global environment variables and manifest configurations.
  • V2 Environment Service Overrides and Environment Variables can override service variables when the service is deployed into a given environment. Based on the variable name, Harness can override the service variable with the environment variable value.
  • Harness has introduced service-specific environment overrides where users can define specific services and variables they want to override for a given environment.
  • For details on environments v2, go to Services and environments overview.

Environment groups​

V2 introduces environment groups. You can now aggregate environments and manage them at scale.

Environment groups are simply a list of environments. You can deploy to a subset of environments within the group or to all of them.

For details on environments groups, go to Services and environments overview.

Environment YAML updates​

environment:
  name: staging
  identifier: staging
  tags: {}
  type: PreProduction
  orgIdentifier: default

      EOT
}

Infrastructure definition​

Harness has taken the infrastructure definition that was originally defined in the pipeline and moved it to the environment. For more information, go to Services and environments overview.

Here are the changes to infrastructure definition:

  • The infrastructure definition can be associated with one environment only.
  • The infrastructure definition is required to run a pipeline execution.
  • Users now need to pick an environment and infrastructure definition.

The infrastructure definition configuration now contains:

  • Name, Description, Tag, Deployment Type.
  • Connector details.
  • Deployment target details.

Infrastructure definition YAML updates​

V2 has the following infrastructure definition changes:

  • The infrastructure definition is now a standalone object not defined in a pipeline.
  • When configuring the infrastructure definition you will associate the infrastructure definition with the environment where you want to use it. For example, the actual cluster in the environment where you want to deploy.
infrastructureDefinition:
  name: product-staging
  identifier: productstaging
  description: ""
  tags: {}
  orgIdentifier: default
  projectIdentifier: Rohan
  
## NOTE: the Environment reference maps the infrastructure definition to the environment

  environmentRef: staging
  deploymentType: Kubernetes
  type: KubernetesDirect
  spec:
    connectorRef: pmk8scluster
    namespace: <+input>.allowedValues(dev,qa,prod)
    releaseName: release-<+INFRA_KEY>
  allowSimultaneousDeployments: false

Infrastructure definition Terraform provider​

Harness has released a new Terraform Provider resource for infrastructure definitions.

New Terraform provider infrastructure definition resource​
resource "harness_platform_infrastructure" "example" {
  identifier      = "identifier"
  name            = "name"

          allowSimultaneousDeployments: false
      EOT
}

Stages​

The stage definition changes when the service and environment v2 update is enabled.

Stages now have a deployment type, a service reference, an environment reference, and an infrastructure definition. These settings must be defined along with the Execution steps of the stage.

    - stage:
        name: Deploy
        identifier: Deploy
        description: ""
        type: Deployment
        spec:
        
 ## SERVICE + ENVIRONMENT v2 UPDATE
 ## deploymentType. This scopes the stage config to one of the deployment types that Harness offers 
 ## Steps, services, environments, infrastructure definitions are all scoped to the stage's deployment type. This prevents incompatible config usage
 
          deploymentType: Kubernetes
          
 ## SERVICE + ENVIRONMENT v2 UPDATE
 ## serviceref. This is now a reference to the service object that is configured and managed outside the pipeline
 ## serviceInputs. These are the runtime inputs that users provide for the artifact when they deploy the particular service
 
          service:
            serviceRef: nginxcanary
            serviceInputs:
              serviceDefinition:

 ## SERVICE + ENVIRONMENT v2 UPDATE
 ## environmentref. This is now a reference to the environment object that is configured and managed outside the pipeline
 ## infrastructureDefinitions. This object is defined outside of the pipeline and is referenced via the identifier. The YAML is inserted into the stage definition once defined

Pipelines​

The following changes apply to pipelines:

  • The pipeline entity changes with the service and environment v2 update.
  • The combination of service, environment, and infrastructure definitions are no longer defined in the pipeline. These entities are now managed outside of the pipeline.
  • Pipelines use identifiers to reference the service, environment, and infrastructure definitions used in the pipeline.
  • Each stage now has a reference to the service, environment, and infrastructure definition entities.

Sample v2 pipeline YAML​

pipeline:
  name: Nginx Colors Canary

Templates​

The following changes apply to v2 templates:

  • Templates are impacted by the service and environments v2 update.
  • Your existing templates in the service and environments v1 experience will run until v1 EOL (see Important dates).
  • When migrating to v2 service and environments, you must create a new stage template that references the v2 service and environment.

Sample stage template​

template:
  name: Deploy
  identifier: Deploy
  type: Stage
  projectIdentifier: Rohan
  orgIdentifier: default
  tags: {}
  spec:
    type: Deployment
    spec:
 
 ## SERVICE + ENVIRONMENT v2 UPDATE
 ## deploymentType. This scopes the stage config to a Harness deployment type.
 ## Steps, services, environments, and infrastructure definitions are all scoped to the stage's deployment type. This prevents incompatible config usage.
 
      deploymentType: Kubernetes
      
 ## SERVICE + ENVIRONMENT v2 UPDATE
 ## serviceref. This is now a reference to the service object that is configured and managed outside the pipeline.

Migrating from v1 services and environments to v2​

note

The user(s) running the APIs for migration must have standard Harness RBAC permissions to update pipelines, services, environments, and templates (if used).

To support automated migration of services and environments, we have created two APIs.

The APIs copy over the v1 serviceDefinition from a pipeline stage and update the existing service with this serviceDefinition.

The APIs also create an infrastructure definition by using the details from the infrastructure.infrastructureDefinition in the YAML of the pipeline stage.

Regardless of whether the pipeline uses templates, the API updates the pipeline YAML also.

Pipeline migration​

The API will migrate services and environments for all CD stages that exist in a pipeline. It can update pipeline YAML also (optional). The API will migrate the CD stages of a pipeline to v2 one by one.

Input fields for account level migration​

  • Authorization. The auth bearer token. It can be extracted from header of network calls from the browser after logging into Harness.
  • accountIdentifier. The user account identifier.
  • orgIdentifier. Organization identifier of the pipeline you want to migrate.
  • projectIdentifier. Project identifier of the pipeline you want to migrate.
  • infraIdentifierFormat. The format for the infrastructure definition identifier. Harness will replace the expressions in this string with actual values and use it as an identifier to create an infrastructure definition.
  • templateMap. Mapping of source template to target template.
    • source template. This refers to a stage template that exists in a CD stage's YAML.
    • target template. This refers to a stage template that replaces the existing source template in a CD stage's YAML.
    • skipInfras. The list of infrastructure identifiers to skip during migration. This allows you to omit infrastructures you don't want to upgrade.
    • skipServices. The list of service identifiers to skip during migration. This allows you to omit services you don't want to upgrade.
    • isUpdatePipeline. The pipeline YAML is updated with the new service and environment framework if this label is true. Otherwise, the pipeline YAML is not updated.

Output fields for account level migration​

  • failures. List of causes for migration failure.
  • pipelineYaml. Updated pipeline YAML with new service and environment framework.
  • migrated. This is true if the pipeline was updated. Otherwise it is false.

Project level migration​

The API will migrate services and enviroments for all existing pipelines in a project. It can update pipeline YAML also.
