Parity Cluster Ansible

A collection of Ansible scripts used in setting up a cluster of Parity nodes.

Currently allows to set up a Docker Swarm Mode cluster on a number of target hosts.

Usage

Provision a few hosts in a cloud of your choice or locally, using VirtualBox or similar software. Take note of their ip addresses, usernames and make sure you have ssh access to these machines.

Populate group_vars/inventory/cluster with the IP addresses, appointing one to be the manager (multiple managers currently not supported) and the others as workers, e.g.

ager]
3.4
ker]
7.8
.11.12
4.15.16

If the ssh username is not “root”, then you can specify it like this, also in the inventory file:

3.4 user=my_username

To configure Docker Swarm, run

pts/init_cluster.sh

This should initialise a new Docker Swarm and connect all listed hosts into a single cluster.

Notes

• All target hosts have to be running Ubuntu 16.04
