Quick 4 nodes Docker Swarm Mode Cluster using Vagrant and Virtualbox#

##This repository will create a working swarm mode cluster for quick deploying, demo and testing of your service and applications. ##

Basic Usage:

1. Download or clone this respository

2. Install Vagrant

3. Install Virtualbox

4. Execute make create to create a new environment (you can use make recreate as well).

5. This will create nodes defined in config.yml and will create the swarm cluster for you (using docker swarm mode). It defaults to for nodes:

• swarmnode1 - manager
• swarmnode2 - manager
• swarmnode3 - manager
• swarmnode4 - worker

4. Connect to nodes using vagrant as usual (vagrant ssh swarmnode1).

5. When you have finnished all your tests, you can execute make stop to stop all nodes or make destroy to destroy your environment (it will delete all nodes and temporary space).

Notes

• Deployment will create 3 interfaces on everynode

• vagrant internal communication (internal)

• internal docker network with ips configured in config.yml (internal)

• bridged interface for connecting to your network using dhcp (external)

• make recreate will destroy your environment and temporary space and create a new one.

• config.yml will let you configure your environment (for example adding more nodes, docker engine version to use and mode, changing default roles, node ips, domain, etc..)

• If you execut vagrant up for each node, you will have the following options:

  • --engine-version - You can choose between 'experimental', 'test' and 'current' versions and deployment will download the required version using its url.
  • --engine-mode - Will let you choose between 'default' or 'experimental'.
  • If none of these options is used, deployment will use config.yml values.
