postgres

Available states

postgres

Installs and configures both PostgreSQL server and client with creation of various DB objects in the cluster.

postgres.client

Installs the PostgreSQL client binaries and libraries.

postgres.manage

Creates such DB objects as: users, tablespaces, databases, schemas and extensions. See pillar.example file for details.

postgres.python

Installs the PostgreSQL adapter for Python.

postgres.server

Installs the PostgreSQL server package, prepares the DB cluster and starts the server using packaged init script, job or unit.

postgres.server.image

Installs the PostgreSQL server package, prepares the DB cluster and starts the server by issuing raw pg_ctl command. The postgres:bake_image Pillar toggles this behaviour. For example:

postgres:
  bake_image: True

If set True, then it becomes possible to fully provision PostgreSQL with all supported entities from postgres.manage state during the build ("baking") of AMI / VM / Container images (using Packer, Docker or similar tools), i.e. when OS init process is not available to start the service and enable it on "boot" of resulting appliance.

Also it allows to make Docker images with PostgreSQL using functionality being available since Salt 2016.11.0 release:

salt 'minion.with.docker' dockerng.sls_build my-postgres base=centos/systemd mods=postgres

If a lookup dictionary or Pillar has postgres:bake_image set False (this is default), it is equivalent of applying postgres.server state.

postgres.upstream

Configures the PostgreSQL Official (upstream) repository on target system if applicable.

The state relies on the postgres:use_upstream_repo Pillar value which could be set as following:

  • True (default): adds the upstream repository to install packages from
  • False: makes sure that the repository configuration is absent

The postgres:version Pillar controls which version of the PostgreSQL packages should be installed from the upstream repository. Defaults to 9.5.

Testing

Testing is done with the kitchen-salt.

kitchen converge

Runs the postgres main state.

kitchen verify

Runs serverspec tests on the actual instance.

kitchen test

Builds and runs tests from scratch.

kitchen login

Gives you ssh to the vagrant machine for manual testing.
