Deployment Notes

The following notes clarify support of some platform features.

Kubernetes: What Can I Deploy?

In Harness, a managed workload is a Deployment, StatefulSet, or DaemonSet object deployed and managed to steady state.

Harness Canary and Blue/Green Workflow default steps support a single Deployment or StatefulSet workload as a managed entity.

Rolling Workflow default steps support Deployment, StatefulSet, or DaemonSet as managed workloads, but not Jobs.

You can deploy any Kubernetes workload in any Workflow type by using a Harness  annotation to make it unmanaged (harness.io/direct-apply).

The  Apply Step can deploy any workloads or objects in any Workflow type as a managed workload.

OpenShift: Harness supports OpenShift DeploymentConfig in OpenShift clusters as a managed workload across Canary, Blue Green, and Rolling deployment strategies. Please use apiVersion: apps.openshift.io/v1 and not apiVersion: v1.

Kubernetes Version Support

The following versions are tested and supported for Kubernetes Canary, Rolling, and Blue/Green deployments:

• 1.13.0
• 1.14.0
• 1.15.0
• 1.16.0
• 1.17.0
• 1.18.0
• 1.19.4
• 1.20.0
• 1.21.0
• 1.22.0
• 1.23.0
• 1.24.3

Currently, Kubernetes command-line tool kubectl binary version 1.19.2 is supported behind the Feature Flag NEW_KUBECTL_VERSION. Contact Harness Support to enable the feature.##### Helm

Harness certifies its Helm support using Helm 3.1.2.

Helm chart dependencies are not supported in Git source repositories (Harness Source Repo Providers). Helm chart dependencies are supported in Helm Chart Repositories.

Artifact Servers, Repos, and Artifacts

Harness uses Metadata only when downloading artifact sources. See Service Types and Artifact Sources.

For pulling Docker images from Docker repos, Harness has a limit of 10000 for private Docker repos, and 250 for public (no username or password required) Docker repos.

Virtual Servers

Harness supports VMs on any platform using the platform-agnostic Physical Data Center deployment type. But Harness has full-fledged API integration only with AWS and Azure, at this time. This integration auto-populates VM names and provides many filtering options usings VPCs, subnets, etc. For VMs on GCP, use the Physical Data Center deployment type in your Harness Infrastructure Definition.

AWS SDK Version Support

Harness supports AWS SDK 1.12.47.

Azure Deployments and Proxy Authentication

Harness uses the Azure SDK among other methods and Authenticated proxy is not supported for Azure SDK. Consequently, you cannot use Azure connections for artifacts, machine images, etc, that require proxy authentication. This is an Azure limitation, not a Harness limitation. This is a known Azure limitation with Java environment properties and their SDK.

Terraform Version Support

Harness does not include Terraform on the Harness Delegate. You must install Terraform on the Delegate when using Terraform in Harness. For more information, go to Terraform How-tos.

Harness supports the following Terraform versions:

• v1.1.9
• v1.0.0
• v0.15.5
• v0.15.0
• v0.14.0

Install a Delegate with custom SDK and 3rd-party tool binaries

To support customization, Harness provides a Harness Delegate image that does not include any third-party SDK binaries. We call this image the No Tools Image.

Using the No Tools Image and Delegate YAML, you can install the specific SDK versions you want. You install software on the Delegate using the INIT_SCRIPT environment variable in the Delegate YAML.

For steps on using the No Tools Delegate image and installing specific SDK versions, see Install a Delegate with 3rd Party Tool Custom Binaries.
