You 16 may want to familiarize yourself with the [key concepts](../key-concepts.md) 17 before you begin. 18 19 The tutorial guides you through the following activities: 20 21 * initializing a cluster of Docker Engines in swarm mode 22 * adding nodes to the swarm 23 * deploying application services to the swarm 24 * managing the swarm once you have everything running 25 26 This tutorial uses Docker Engine CLI commands entered on the command line of a 27 terminal window. You should be able to install Docker on networked machines and 28 be comfortable running commands in the shell of your choice. 29 30 If you’re brand new to Docker, see [About Docker Engine](../../index.md). 31 32 ## Set up 33 34 To run this tutorial, you need the following: 35 36 * [three networked host machines](#three-networked-host-machines) 37 * [Docker Engine 1.12 or later installed](#docker-engine-1-12-or-later) 38 * [the IP address of the manager machine](#the-ip-address-of-the-manager-machine) 39 * [open ports between the hosts](#open-ports-between-the-hosts) 40 41 ### Three networked host machines 42 43 The tutorial uses three networked host machines as nodes in the swarm. These can 44 be virtual machines on your PC, in a data center, or on a cloud service 45 provider. This tutorial uses the following machine names: 46 47 * manager1 48 * worker1 49 * worker2 50 51 ### Docker Engine 1.12 or later 52 53 To use swarm mode, you must [install Docker Engine](../../installation/index.md) 54 on each one of the host machines. Alternatively, install the latest Docker for 55 Mac or Docker for Windows. 56 57 >**Note**: Docker for Mac and Docker for Windows let you use single-node 58 features of swarm mode, like creating a swarm and creating a service. Multi-node 59 features like joining additional nodes and scaling a service are not available. 60 61 Verify that the Docker Engine daemon is running on each of the machines. 62 63 ### The IP address of the manager machine 64 65 The IP address must be assigned to an a network interface available to the host 66 operating system. All nodes in the swarm must be able to access the manager at the IP address. 67 68 Because other nodes contact the manager node on its IP address, you should use a 69 fixed IP address. 70 71 >**Tip**: You can run `ifconfig` on Linux or Mac OS X to see a list of the 72 available network interfaces. 73 74 The tutorial uses `manager1` : `192.168.99.100`. 75 76 ### Open ports between the hosts 77 78 * **TCP port 2377** for cluster management communications 79 * **TCP** and **UDP port 7946** for communication among nodes 80 * **TCP** and **UDP port 4789** for overlay network traffic 81 82 ## What's next? 83 84 After you have set up your environment, you're ready to [create a swarm](create-swarm.md).
