// how it works

How it works

  1. Install Portainer CE

    Create a data volume and run the portainer/portainer-ce container with the Docker socket mounted, per the official install docs.

  2. Create the admin user

    Open https://localhost:9443 within a few minutes of first start (the installer times out for security if you wait) and set the admin password.

  3. Manage your environment

    Portainer connects to the local Docker environment automatically; add remote environments or Kubernetes clusters from the same UI.

// features

Why people love it

One UI for every runtime

Docker, Swarm, Podman, Kubernetes and ACI environments side by side in a single dashboard.

Deploy without the CLI

Create and edit containers and compose stacks in forms and a built-in editor, with logs and console access in the browser.

Multi-environment by design

Manage the homelab, the VPS and the office cluster from one login, with per-environment access in Business Edition.

Trivially self-hosted

Portainer is one container mounting the Docker socket — the manager is as easy to run as the things it manages.

// run it

Run it yourself

  1. Docker run (CE)

    The documented Community Edition install.

    docker volume create portainer_data
    docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:lts
  2. Open the UI

    Do this promptly — first-run setup locks after a short timeout.

    https://localhost:9443
  3. Deploy your first stack

    In the UI: Stacks → Add stack, paste a docker-compose file, deploy. Portainer shows logs, stats and console for every container it starts.

Questions, answered

Who makes Portainer?

Portainer.io, the company behind the open-source project (portainer/portainer on GitHub), which funds development through the Business Edition.

Is Portainer free?

The Community Edition in this repository is free and open source (Zlib licence). Business Edition adds enterprise features and support under a commercial licence.

Is it safe to mount the Docker socket?

The socket is root-equivalent access to the host, so protect your Portainer login accordingly — strong password, HTTPS, and do not expose it to the open internet without thought.

How does it compare to a well-known alternative?

Against the Docker CLI, Portainer trades keystrokes for visibility — logs, stats and deploys in one screen. Against Rancher, it is far lighter and simpler for small fleets; Rancher goes deeper on large-scale Kubernetes governance.

How do I get started?

Run the portainer/portainer-ce:lts container with the Docker socket mounted, then open https://localhost:9443.
