Managing Configurations

XOS comes with several pre-configured environments. The main available configurations are:

• Frontend Only
• CORD Every configuration comes with different settings and different features, from GUI elements to Services.

NOTE: files should not be added by hand to this folder. They will break the configuration system.

Basic configuration

A common configuration file is saved in xos/configurations/common/xos_common_config. This file stores all the common configurations for XOS.

This is the base config: `` [plc] name=plc deployment=plc

[db] name=xos user=postgres password=password host=localhost port=5432

[api] host=localhost port=8000 ssl_key=None ssl_cert=None ca_ssl_cert=None ratelimit_enabled=0 omf_enabled=0 mail_support_address=support@localhost nova_enabled=True logfile=/var/log/xos.log

[nova] admin_user=admin@domain.com admin_password=admin admin_tenant=admin url=http://localhost:5000/v2.0/ default_image=None default_flavor=m1.small default_security_group=default ca_ssl_cert=/etc/ssl/certs/ca-certificates.crt

[observer] pretend=False backoff_disabled=False images_directory=/opt/xos/images dependency_graph=/opt/xos/model-deps logfile=/var/log/xos_backend.log

[gui] disable_minidashboard=True branding_name=Open Cloud #branding_css= #no branding css is provided by default branding_icon=/static/logo.png

``

Extending configuration

How it works

In some environments changes to the configuration are needed. To achieve this, XOS reads configurations from a xos/xos_configuration.

All the configuration files in this folder are parsed with ConfigParser.

Extending a configuration

An example is available in the CORD config

These are the basic step to extend a configuration. The following uses myConf as a placeholder for the current configuration.

Local Config

• In your configuration create a new config file named: xos_<myConf>_config Sample local config: [gui] branding_name=A BRAND NAME branding_icon=/static/my_logo.png

The file above will change the displayed brand name and the logo in the UI

Makefile Changes

• Clean the configuration folder: rm ../../xos_configuration/*
• • Add the common config: cp ../common/xos_common_config ../../xos_configuration/
• • Add the local config: cp ./xos_<myConf>_config ../../xos_configuration/ IMPORTANT: this instructions have to be executed before docker build
