Portainer Introduction and Usage Guide for Docker Management

Portainer is a graphical management tool for Docker that offers status panels, quick deployment templates, basic operations for containers, images, networks, volumes, Swarm clusters, user management, and more, meeting the needs of small to medium‑sized environments.

Downloading the Portainer image

# Query available Portainer images
docker search portainer

The first listed image docker.io/portainer/portainer is typically used:

# Pull the image
docker pull docker.io/portainer/portainer

Running Portainer on a single Docker host

docker run -d -p 9000:9000 \
    --restart=always \
    -v /var/run/docker.sock:/var/run/docker.sock \
    --name portainer-test \
    docker.io/portainer/portainer

After starting, access the UI at http://IP:9000 , register the admin user, choose the local Docker endpoint, and begin managing containers, images, and volumes.

Cluster mode with Docker Swarm

Portainer also supports managing Docker Swarm clusters. After setting up a Swarm, start Portainer similarly:

docker run -d -p 9000:9000 --restart=always --name portainer-test docker.io/portainer/portainer

Log in as admin, then add remote endpoints by providing a name and the Swarm node URL (e.g., 10.0.11.152:2375 ). Once added, you can view and manage nodes, containers, images, and services across the cluster.

The UI also allows image pull/push, tag management, repository configuration, and permission settings.
