# postgres The postgres role will install Postgresql software and configure a database and user to support an Artifactory or Xray server. ### Role Variables By default, the [_pg_hba.conf_](https://www.postgresql.org/docs/13/auth-pg-hba-conf.html) client authentication file is configured for open access for development purposes through the _postgres_allowed_hosts_ variable: ``` postgres_allowed_hosts: - { type: "host", database: "all", user: "all", address: "0.0.0.0/0", method: "trust"} ``` **THIS SHOULD NOT BE USED FOR PRODUCTION.** **Update this variable to only allow access from Artifactory, Distibution, MissionControl and Xray.** ## Example Playbook ``` --- - hosts: postgres_servers roles: - postgres ```
