A playground for Docker Swarm Using Vagrant

Local Docker Swarm Testing

System Requirements

• Vagrant
• Ansible

Setup

Build the base Vagrant box make build

The make command really handles everything that needs to be done.

Building a Swarm

Here is an example Vagrantfile that uses the new box to build out a 3 node swarm.

Each node has remote docker-engine enabled (insecure/non-tls). You can access a node directly via ssh (vagrant ssh swarm01) or via the remote docker-engine (DOCKER_HOST=192.168.33.10 docker swarm node ls)

This Vagrant box also has vboxsf installed. This will allow you to easily setup a shared directory with all nodes for storage. (e.g. config.vm.synced_folder './data', '/src/docker')

Note: The swarm will have to be manually initiated and each node will need to be manually added.

    v.vm.hostname = "swarm03"
    v.vm.network "private_network", ip: "192.168.33.12"
  end
