General

This git repository holds anything needed to give a demo of SplendidData Postgres Pure. Basic aproach is that you

• create a docker image of fedora or centos
• use that image to spin 4 docker containers
• use ansible to
  • configure one as a repo and
  • install postgres, repmgr and barman from that repo

Step by step

Start the docker containers

docker-compose up -d

Change default config if needed

Only needed for

• non default docker deployments, or with already running containers
• switching between centos / fedora (default is centos)
• switching to pure3 (default is pure4) Look at
• ansible/group_vars/all for all preconfigured variables
• ansible/staging/inventory for all hostrelated stuff

Run playbook all.yml, or repo.yml, then repmgr.yml and then barman.yml

• all.yml calls all the other playbooks in the correct order
• repo.yml initializes repo container
• repmgr.yml initializes database servers, making first server a master and the rest a standby (only one standby is tested for now)
• barman.yml initializes database servers as barman clients and barman server as barman server

ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook ansible/all.yml -i ansible/staging/inventory -u root --private-key docker/c7_ssh/id_rsa

Cleanup

Cleanout docker containers

• docker-compose kill
• docker-compose rm
