Portainer, one of the most widely deployed container management interfaces, is making a dramatic enterprise pivot. CEO Neil Cresswell announced on September 11 that version 2.45 LTS is the final release of the 2.x line. The upcoming 3.0 release will be Kubernetes-first, with Docker, Podman, and Docker Swarm support handled through a new compatibility tool called d2k (Docker-to-Kubernetes-Translator) that translates Docker commands into Kubernetes operations within a namespace.
The Community Edition will remain frozen on the 2.x codebase, receiving only security patches and bug fixes. Selective features may be backported, but the timeline is indefinite. Cresswell argued that the next generation of applications and AI agents requires infrastructure complexity that Docker cannot provide.
New products including Portainer-Run, Portainer-IDP, and Portainer-Command (an MCP gateway for AI agents) will be Kubernetes-only. Docker users can still access free Business Edition keys for up to three nodes under the 3 Nodes Free program, but the source code is no longer public.
The community reaction has been sharp. Users are debating alternatives such as Komodo, Arcane, Dockge, and Dockhand. The core complaint: Kubernetes is overkill for most self-hosting and homelab use cases, and removing first-class Docker support from a tool that made Docker accessible is a significant regression.
