Windows Server 2019 Agent Containers End of Life
Jenkins core stopped supporting Windows Server 2019 container images in Jenkins 2.569 and Jenkins 2.568.1. It is now time to drop Windows Server 2019 container images for the inbound agent container images and the SSH agent container images.
Effective August 21, 2026, the Jenkins project will no longer deliver container images based on Windows Server 2019. We will continue to deliver container images based on newer versions of Windows Server, like Windows Server 2022 and Windows Server 2025.
For users running Windows Server 2019 for their agents, the alternatives are:
-
Upgrade to Windows Server 2022 or Windows Server 2025
-
Build their own agent image for Windows Server 2019
Windows Server 2019 was retired from the Azure Kubernetes Service (AKS) on March 1, 2026. Azure Kubernetes Service no longer provides new node images or security patches. Existing node pools with Windows Server 2019 are unsupported.
More details are available in the inbound agent issue and the SSH agent pull issue.
