clldappconfig 1.2.0

Remote control for DLCE apps

clldappconfig

Scripted deployment and management of clld web apps. This package provides the appconfig command line utility as well as fabric tasks which can be used in fabfiles for managing individual apps.

command line utility usage

To show a help message run

appconfig --help

The appconfig command needs a configuration directory containing the global configuration file (apps.ini) and the config scripts all managed apps. I.e. the config directory (here apps/) should have the following structure:

apps
├── apps.ini
├── README.md
├── abvd
│   ├── fabfile.py
│   ├── README.md
│   └── requirements.txt
├── acc
│   ├── fabfile.py
│   ├── README.md
│   └── requirements.txt
.
.
.

The config discovery is done in the following order:

1. use argument of --config / -c
2. use the APPCONFIG_DIR environment variable
3. by default the current working directory (./) is assumed to be the config directory

So both of the following commands do the same thing:

appconfig --config ./path/to/appconfig/apps/ ls
env APPCONFIG_DIR=./path/to/appconfig/apps/ appconfig ls

using fabfiles

For every app should provide a subdirectory of the config directory, which contains a fabfile.py with the following minimal structure:

from clldappconfig.tasks import *

init()

Inside the directory containing the fabfile you can run fab -l to list all available tasks for deployment, managing databases etc.

Config discovery for the fabfiles works as follows:

1. use the APPCONFIG_DIR environment variable
2. by default the parent of the current working directory (../) is assumed to be the config directory

If you use the config directory structure as described above, you can rely on the default behavior and usually don't need to set the APPCONFIG_DIR environment variable.
