Deployment notes
The following notes clarify support of some platform features.
Kubernetes
See What Can I Deploy in Kubernetes?.
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
For details on other tools and versions included in Harness, see Delegate-required SDKs.
Guidelines:
- Harness will officially support 3 previous versions from the last stable release. For example, the current most recent stable release is 1.24.3, and so Harness supports 1.23, 1.22, and 1.21.
- Harness supports any other versions of Kubernetes you are using on a best effort basis.
- Harness commits to support new minor versions within 3 months of the first stable release. For example, if the stable release of 1.24.3 occurs on August 15th, we will support it for compatibility by November 15th.
Helm
Helm chart dependencies are not supported in Git source repositories. Helm chart dependencies are supported in Helm Chart Repositories.
Artifact servers, repos, and artifacts
Harness uses Metadata only when downloading artifact sources.
For pulling Docker images from Docker repos, Harness is restricted by the limits of the Docker repo. For example, Docker Hub limits.
The maximum number of artifact image tags fetched by Harness that is 10000.
The following table lists Harness integrations and their artifact source support:

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:
- v1.3.5
- v1.1.9
- v1.0.0
- v0.15.5
- v0.15.0
- v0.14.0
Here's an example install script for the Harness delegate:
# Install TF
microdnf install unzip
curl -O -L https://releases.hashicorp.com/terraform/1.3.5/terraform_1.3.5_darwin_amd64.zip
unzip terraform_1.3.5_darwin_amd64.zip
mv ./terraform /usr/bin/
# Check TF install
terraform --version
Some Harness features might require specific Terraform versions.
Azure AKS clusters
To use an AKS cluster for deployment, the AKS cluster parameter disableLocalAccounts can be set either true or false.
AWS and Azure GovCloud
Harness is now certified in Azure GovCloud and AWS GovCloud.
GitOps
Harness GitOps lets you perform GitOps deployments in Harness. You define the desired state of the service you want to deploy in your Git manifest, and then use Harness GitOps to sync state with your live Kubernetes cluster.
GitOps supports the following:
- Source Repositories:
- All Git providers.
- HTTP Helm repos.
- Target clusters:
- Kubernetes clusters hosted on any platform:
- GKE.
- AKS.
- EKS.
- Other Kubernetes-compliant clusters.
- OpenShift version 3.11, 4.x.
- Minikube.
- Kubernetes Operations (kops).
- Kubernetes clusters hosted on any platform:
- Repository Certificates:
- TLS Certificate (PEM format).
- SSH Known Host Entry.
- GnuPG Keys:
- GnuPG Public Key Data (ASCII-armored).

|---|---|---|---|---|---|---|---|
| Kubernetes Cluster | Kubernetes - GKE - AKS - EKS | Yes | Yes | Prometheus, Grafana | Supported | Supported |
Supported Kubernetes versions for Harness Self-Managed Enterprise Edition
- Self-Managed Enterprise Edition supports Kubernetes v.1.23. Self-Managed Enterprise Edition additionally supports Kubernetes versions 1.22, 1.21, and 1.20.
- Effective October 7, 2022, with the release of version 76918, Self-Managed Enterprise Edition no longer supports Kubernetes open-source versions 1.18 and earlier.
- Self-Managed Enterprise Edition supports the other versions of Kubernetes you use on a best-effort basis.
- Harness commits to support new minor versions of Kubernetes within three months of the first stable release. For example, if the stable release of 1.24.0 occurs on August 31, Harness extends compatibility by November 30.
Terms of support for Harness Self-Managed Enterprise Edition
Harness Self-Managed Enterprise Edition does not introduce changes that break compatibility with supported versions of Kubernetes. For example, Self-Managed Enterprise Edition does not use features from Kubernetes version n that do not work in Kubernetes version n-2.
Installation and upgrade preflight checks provide warnings when you use Kubernetes versions that are not supported.
In cases where you encounter a problem that is related to an incompatibility issue, you must upgrade your cluster. Harness will not issue a patch to accommodate the use of unsupported Kubernetes versions.
SDKs installed with the Delegate
Harness Delegate includes binaries for the SDKs that are required for deployments with Harness-supported integrations. These include binaries for Helm, ChartMuseum, kubectl, Kustomize, and so on.
Kubernetes Deployments
For Kubernetes deployments, the following SDKs/tools are included in the Delegate.
- kubectl: v1.13, v1.19
- Helm: v2.13.1, v3.1.2, v3.8.0
- Kustomize: v3.5.4, v4.0.0

The versions can be found in this public GitHub repo: https://github.com/harness/harness-core/tree/develop/960-api-services/src/main/java/io/harness/delegate/clienttools
For details on updating the default tool versions, see Build custom delegate images with third-party tools.
For Kubernetes deployments, the following SDKs/tools are certified.
| Manifest Type | Required Tool/SDK | Certified Version |
| Kubernetes | kubectl | v1.24.3 |
| go-template | v0.4 | |

| Helm Chart | helm | v3.9.2 |
| kubectlRequired if Kubernetes version is 1.16+. | v1.24.3 |
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.
The Update Framework (TUF)
The Update Framework (TUF) is an open source specification for that provides instructions on how to organize, sign, and interact with metadata to secure package managers.
Harness includes native TUF support via the following:
- Deployment templates: Deployment Templates use shell scripts to connect to target platforms, obtain target host information, and execute deployment steps.
- Deployment Templates can obtain the required metadata for native TUF support, and generate and validate signatures in the software lifecycle.
- OCI image registry support:
- TUF recommends the use of an OCI image-spec container registry. Harness supports OCI registry for Helm charts.
- Enforce the rotation of secrets and key management practices:
- Harness provides token key rotation natively.
- Continuous Verification: TUF recommends the verification of deployments akin to Harness Continuous Verification.
