fabfile.py automation for repeating maintenance tasks
=====================================================

In our company we have automated a lot of project life cycle repeating actions. Most of them are straightforward & easy to use.

### fab up

In most of projects we implement get\_db and reinst\_db scripts. First one downloads the most recent copy of the production database,
2nd command installs it. Typically the end user-developer needs to run this to get his project fully updated:

    hg pull -uv
    fab get_db reinst_db depup patch

And usually in most of projects all this gets combined in a single command:

    fab up

which implements the following:
- **hgup** - (hg pull —update) - update to most recent source code
- **get\_db** - download latest production database
- **reinst\_db** - drop & reinstall current database from latest backup made
- **depup** ~~update external source dependencies
~~ **patch** - apply migration patches to the project

And so Fabric abstracts it on a higher level, and makes developer life easier.

### fab produp

Additionally on every production server the ‘produp’ procedure gets implemented. It is very similar to
‘up’ procedure explained above, but it also includes step to reload / restart production service software
and update required files (for example static files).

And so,

    fab produp

consists from:

* hgup
 \* depup
 \* patch
 \* prod\_reload
 \* ./manage.py collectstatic
