Delegate Connection Requirements
This article lists the permissions and ports required by the Harness Delegate to access your artifact servers, cloud providers, verification, and security providers.
How does Harness Connect to Providers?
The Harness Manager connects to the artifact servers, cloud providers, verification, and security providers using the Harness Delegate. You download the Harness Delegate from the Harness Manager and install it in your network or VPC.
For information on Harness architecture, see Harness Architecture.
The Delegate only connects to the Harness Manager via an outbound HTTPS connection over port 443. There is no inbound connection from the Harness Manager to the Delegate.
In the Harness Manager, you configure artifact servers, cloud providers, verification, and security providers using your account credentials with those providers. The Delegate uses those credentials when it uses your providers in the Harness deployment, verification, and security processes.
Harness Delegate Connection to Harness Manager
The Delegate runs from within your enterprise network or VPC and only connects to the Harness Manager with a secure outbound HTTPS connection over port 443.
- HTTPS port 443 outbound from locally-installed delegate to the Harness Manager.
- HTTPS port 443 from your browser to the Harness Manager.
Permissions and Ports for Harness Connections
The following table lists the permissions and ports needed for the Harness Delegate to access artifact servers, cloud providers, verification, and security providers. You configure these settings in the Harness Manager.
- Artifact servers: The Delegate pulls artifacts and metadata from artifact servers using the account and ports required by the artifact server.
- Deployments: Most Harness deployments to Virtual Machines (for example, AWS, GCP, Azure, Datacenter) are performed using SSH over port 22. The VPC firewall setting might also require additional open ports for administration, such as HTTP 443.
- Verifications: The Delegate makes API calls to verification providers using the access keys required by the providers.
- Security: For security, such as SAML and LDAP, the Delegate uses the account and ports required by the provider, such as a Active Directory domain controller running in a Azure or AWS VPC.
