Portainer is an open-source tool designed to simplify container management. It provides a web-based user interface that allows you to easily manage Docker, Kubernetes, and Swarm environments. By abstracting the complexity of container orchestration, Portainer enables developers and IT operations teams to deploy, monitor, and manage containers with ease.
Portainer is comprised of two main components:
Portainer offers a wide range of features, including:
Before installing Portainer, ensure you have:
Deploy Portainer Server
For a Docker standalone environment, run:
docker run -d -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce
For Docker Swarm, first create a Docker volume:
docker volume create portainer_data
Then deploy Portainer as a service:
docker service create --name=portainer --publish=9000:9000 --replicas=1 --constraint='node.role==manager' --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock --mount=type=volume,src=portainer_data,dst=/data portainer/portainer-ce
(Optional) Deploy Portainer Agent
For environments with multiple nodes, deploy the Portainer Agent on each node to enable full management capabilities:
docker run -d -p 9001:9001 --name=portainer_agent --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker/volumes:/var/lib/docker/volumes portainer/agent
After installation, access the Portainer web UI by navigating to http://<YOUR-IP>:9000 in your web browser. The setup wizard will guide you through the initial configuration, including setting up an admin account.
