Scripts to create and manage a Docker Swarm cluster on Google Cloud Platform.
Before you start
Make sure you create a Google Cloud Project
You need to enable Google Cloud Deployment Manager V2 API using this link.
Create a Cluster
By default, this will create a cluster with one manager and two workers. You can edit this and more options in the options.yaml file.
Delete a Cluster
Resize a Cluster
Edit the options.yaml file to specify your options.
- Cluster Configuration Options
prefix= All nodes in the Swarm will start with this Prefix. This allows you to have multiple Swarms in the same project.
zone= Google Cloud Zone for the nodes - default: us-central1-f
- Manager Options
manager_machine_type= Google Cloud Machine Type for the Manager nodes - default: n1-standard-1
manager_disk= Disk size in GB for the Manager nodes - default: 100
- Worker Options
num= Number of Workers for the Cluster - default: 2
worker_machine_type= Google Cloud Machine Type for the Worker nodes - default: n1-standard-1
worker_disk= Disk size in GB for the Worker nodes - default: 100
How it works
These scripts are simple wrappers around a set of Deployment Manager templates.
It launches a VM for the Swarm Manager, and a Managed Instance Group for the workers.
This allows you to dynamically scale the number of workers as well as easily create Network Load Balancers that target the worker nodes.
Docker-Machine is used to connect to the Manager node over a secure TLS connection
