OSHA OiRA Statistics Deployment

This package contains configuration and scripts for deploying the OSHA OiRA statistics. The buildout configuration sets up a number of metabase instances to serve the statistics and generates scripts to manage them.

Setup

Quickstart

Create a buildout.cfg like this:

[buildout]
extends =
    base.cfg
    secrets.cfg

[secrets]
<= secrets-production

Run

# make

Installation / Update

One-Shot

If you're installing for the first time, you need to make sure the databases are created (see below). If you're updating an existing installation, it's usually enough to call

# make

or, equivalently,

# make all

This sets up everything in one go except for creating the databases - you may need to do this as a privileged user, and it's unnecessary to run on every update, so it's not included by default. See "Creating the Databases" for instructions.

Step-By-Step

If the one-shot setup fails for some reason or you're interested in the details, read on for a step-by-step setup.

If you're in an environment with managed secrets, decrypt the secrets file with:

# gpg -d secrets.cfg.gpg > secrets.cfg

Create a buildout.cfg that extends base.cfg and, if you're using it, secrets.cfg.

[buildout]
extends =
    base.cfg
    secrets.cfg

Make sure that there is a secrets section in your buildout.cfg and that it inherits from the correct section in secrets.cfg.gpg:

[secrets]
<= secrets-production

Otherwise set the passwords manually:

[secrets]
metabase-password = secret
ldap-password = secret

If you want to bind to a different address than localhost, set the metabase-host:

[metabase-instance]
metabase-host = oira.local

Then, as usual, run:

# bin/buildout

Alternatively, decrypting and running buildout is done by

# make buildout

Creating the Databases

During the first setup or if you get an error like

psql: FATAL:  database "xyz" does not exist

you will need to initialize the postgresql databases. Make sure

• buildout has run sucessfully (make buildout or bin/buildout)
• PSQL_USER (see Makefile) is set to a user who may create postgresql databases
• your current user can use sudo to become PSQL_USER

Once you're set, run

# make create-databases

or, if you're already logged in as an appropriate user

# psql -U postgres < scripts/create-databases.sql

and then retry make all.

Usage

Getting started

If you've run make all successfully, you can skip this section.

To set up the metabase instances:

# bin/init-metabase

or

# make init-metabase

This calls bin/init-metabase-instance (see below) for all instances with the parameters specified in the corresponding buildout sections.

After that you can log in to the metabase instances with the credentials you provided in the buildout configuration.

Making changes

To make changes to the metabase content, modify the data in oira.statistics.deployment.content. It may be convenient to make changes via the UI and then get the corresponding values via the API. You can use the ipybase shell defined in devel.cfg for this purpose.

To apply the changes to the global and country instances, again run

# bin/init-metabase

init-metabase-instance

Applies settings to a single metabase instance. Sets database connection parameters and optionally creates an additional user. Run init-metabase-instance --help for arguments.

init-metabase

Initializes all metabase instances by dropping all database content and running init-metabase-instance on each of them. Does not take any parameters; buildout writes them directly into the script. If the environment variable SKIP_DB_RESTORE is set, database contents are not dropped but kept.
