Install Portainer BE with Docker Swarm on Linux
Portainer consists of two elements, the Portainer Server and the Portainer Agent. Both elements run as lightweight Docker containers on a Docker engine. This document will help you deploy the Portainer Server and Agent containers on your Linux environment. To add a new Linux Swarm environment to an existing Portainer Server installation, please refer to the Portainer Agent installation instructions.
To get started, you will need:
- The latest version of Docker installed and working
- Swarm mode enabled and working, including the overlay network for the swarm service communication
sudoaccess on the manager node of your swarm cluster
- By default, Portainer will expose the UI over port
9443and expose a TCP tunnel server over port
8000. The latter is optional and is only required if you plan to use the Edge compute features with Edge agents.
- The manager and worker nodes must be able to communicate with each other over port
- A license key for Portainer Business Edition.
The installation instructions also make the following assumptions about your environment:
- You are accessing Docker via Unix sockets. Connecting via TCP is not supported in Docker Swarm.
- SELinux is disabled on the machine running Docker.
- Docker is running as root. Portainer with rootless Docker has some limitations, and requires additional configuration.
- If your nodes are using DNS records to communicate, that all records are resolvable across the cluster.
Portainer can be directly deployed as a service in your Docker cluster. Note that this method will automatically deploy a single instance of the Portainer Server, and deploy the Portainer Agent as a global service on every node in your cluster.
Only do this once for your environment, regardless of how many nodes are in the cluster. You do not need to add each node in your cluster as a separate environment in Portainer. Deploying the manifest to your swarm will include every node in the cluster automatically. Adding each node as a separate environment will also consume more of your licensed node count than you may expect.
First, retrieve the stack YML manifest:
curl -L https://downloads.portainer.io/ee2-19/portainer-agent-stack.yml -o portainer-agent-stack.yml
Then use the downloaded YML manifest to deploy your stack:
docker stack deploy -c portainer-agent-stack.yml portainer
Portainer Server and the Agents have now been installed. You can check to see whether the Portainer Server and Agent containers have started by running
root@manager01:~# docker ps

Now that the installation is complete, you can log into your Portainer Server instance by opening a web browser and going to:
localhostwith the relevant IP address or FQDN if needed, and adjust the port if you changed it earlier.
You will be presented with the initial setup page for Portainer Server.
