To run this repo is necessary to install:

• GNU Make
• Docker: https://docs.docker.com/get-docker/
• Vagrant: https://developer.hashicorp.com/vagrant/downloads
• Docker Provider for Vagrant: https://developer.hashicorp.com/vagrant/docs/provisioning/docker

Tested on M1 and intel macbooks.

Usage

To create the vms, run:

make create-machines

Once the were created, test the ansible connection:

make ansible-ping

If the connection working, setup patroni in the nodes:

make ansible-setup

checking if patroni is working

connect in any of the nodes, like below:

ssh -F vagrant-ssh.cfg db-node-1

In the node run:

sudo su - postgres -c "patronictl -c /etc/patroni.yaml topology"
