Portainer: a lightweight GUI for Docker and Kubernetes

TL;DR

• Portainer Community Edition is a lightweight, open-source GUI and API for managing containerized applications across Docker, Docker Swarm, Kubernetes and ACI environments.
• It ships as a single container that runs on any cluster, deployable as a Linux container or a Windows native container.
• From one "smart" web UI you manage orchestrator resources: containers, images, volumes, networks, stacks and more.
• It is licensed under the zlib license (a permissive open-source license), and a separate commercial Portainer Business Edition adds advanced features like RBAC and vendor support.
• Latest release at the time of writing is 2.39.4 LTS, by Portainer (Portainer.io).

What is Portainer?

Portainer Community Edition is, in the project's own words, a lightweight service delivery platform for containerized applications. It gives you a graphical interface and an extensive API to manage Docker, Swarm, Kubernetes and ACI environments without memorising every CLI flag. The whole product is a single container that can run on any cluster, and it is designed to be as simple to deploy as it is to use. That low-friction model is a big part of why it became a fixture in homelabs and production stacks alike.

What can it manage?

Through a single "smart" GUI, or its API, Portainer lets you manage all your orchestrator resources: containers, images, volumes, networks and more. It supports Docker standalone, Docker Swarm, Kubernetes and Azure Container Instances (ACI), so the same console can sit in front of very different backends. You deploy and inspect stacks, browse and pull images, attach volumes, wire up networks and watch container state, all from the browser instead of juggling shell sessions across hosts. The result is one pane of glass over heterogeneous container infrastructure.

How do you deploy it?

Portainer's appeal starts with deployment: it is a single container, so getting it running is a couple of commands. The project recommends consulting the official install guide for your platform, since the exact steps differ between Docker, Swarm and Kubernetes. The general Docker pattern is to create a named volume for Portainer's data and then run the Portainer image, exposing its UI port. A typical Docker-based bring-up looks like this:

docker volume create portainer_data

docker run -d -p 9443:9443 --name portainer \
  --restart=always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce

Mounting the Docker socket lets Portainer talk to the local Docker engine; the named volume keeps your configuration and settings across restarts. For Swarm, Kubernetes or Windows native containers, follow the matching path in the documentation. Because it is just one container, you can tear it down and redeploy without disturbing your workloads.

CE vs Business Edition?

This repository is Portainer Community Edition (CE), the open-source product, and it is licensed under the zlib license. CE is free to use, alter and redistribute, including in commercial settings, subject to the zlib license's short attribution and "don't misrepresent the origin" conditions. Separately, Portainer Business Edition (BE) builds on the open-source base and adds a range of advanced features and functions, such as role-based access control (RBAC) and commercial support, that are specific to the needs of business users. Portainer offers a "Take 3" option giving three free nodes of Business Edition, and publishes a feature comparison between CE and BE. The distinction matters: the code in this repo is the open-source CE, while BE is a separate commercial offering from Portainer.

Who is it for?

Portainer suits anyone who wants the power of container orchestration without living in the terminal. Homelab and self-hosting enthusiasts get an approachable way to run and watch their Docker stacks. Small teams and DevOps engineers get a consistent console across Docker, Swarm and Kubernetes, plus an API for automation. Operators managing Windows or Linux container hosts get a single tool that spans both. It is supported as an open-source project by its community, with a paid, supported edition available for organisations that need RBAC and vendor backing.

FAQ

Is Portainer made by Navanem?

No. Portainer is an open-source project created and maintained by Portainer (Portainer.io / Portainer, Inc.). Navanem did not build it and is not affiliated with it. This page is simply an editorial spotlight; navanem publishes the write-up, but every bit of credit for the software belongs to the Portainer team.

Is Portainer free and open source?

Yes. Portainer Community Edition, the product in this repository, is open source under the zlib license, a permissive license that allows free use, modification and redistribution, including in commercial applications. A separate commercial Portainer Business Edition exists with additional features and support, but CE itself is free.

What container platforms does Portainer support?

According to the project, Portainer can manage Docker, Docker Swarm, Kubernetes and Azure Container Instances (ACI) environments. It runs as a single container and can be deployed as a Linux container or a Windows native container, so it spans a wide range of host setups.

What is the difference between Portainer CE and Business Edition?

CE is the open-source edition under the zlib license, free to deploy and use. Business Edition builds on that same open-source base and layers on advanced capabilities such as RBAC and official support aimed at business users. Portainer publishes a side-by-side feature comparison and offers a free three-node tier of Business Edition.

What language is Portainer written in?

Portainer is built with a Go backend and a TypeScript front end. The frontend consumes a TypeScript API client that is generated from the Go API's Swagger annotations, so the two stacks stay in sync as the API evolves.
