Docker：Swarms

Prerequisites

• Install Docker version 1.13 or higher.

• Get Docker Compose as described in Part 3 prerequisites.（.yaml）

• Get Docker Machine, which is pre-installed with Docker for Mac and Docker for Windows, but on Linux systems you need to install it directly. On pre Windows 10 systems without Hyper-V, as well as Windows 10 Home, use Docker Toolbox.

• Read the orientation in Part 1.

• Learn how to create containers in Part 2.

• Make sure you have published the friendlyhello image you created by pushing it to a registry. We use that shared image here.

• Be sure your image works as a deployed container. Run this command, slotting in your info for username, repo, and tag: docker run -p 80:80 username/repo:tag, then visit http://localhost/.

• Have a copy of your docker-compose.yml from Part 3 handy.
